Die Öffnung des deutschen Bilanzrechts bewirkt eine zunehmende Anwendungsbreite von internationalen Rechnunungslegungsnormen (wie insbesondere der US-GAAP und der IAS) für deutsche Rechtsanwender;1 die heterogenen Normtypen und die – damit einhergehend – unterschiedlichen ökonomischen Eigenschaften dieser Normen erfordern für einen sinnvollen Rechnungslegungsvergleich eine komparative Rechnungslegungstheorie. Eine Besinnung auf die ökonomische Theorie ist – auch ausgelöst durch die Internationalisierung der Rechnungslegung – hier grundsätzlich festzustellen,2 wie auch das moderne deutsche Bilanzrecht seine heutige Prägung durch die ökonomische Theorie – und nicht vornehmlich durch die Anwender – erhielt.3 Es ist das Ziel des Aufsatzes, einen Beitrag zu einer institutionenökonomischen Theorie der Rechnungslegung zum Zweck der Bestimmung von Informationsinhalten und Gewinnansprüchen sowie zur vergleichenden Rechnungslegungstheorie zu leisten. In einem ersten Hauptteil (2) wird im folgenden – auf dem institutionenökonomischen Forschungsprogramm aufbauend – skizziert, welche Bedeutung Institutionen im Rahmen des Nutzenkalküls von Entscheidern zuzumessen ist; danach werden die einzelnen für eine vergleichende Rechnungslegung relevanten Institutionsarten typisiert (in formale und informelle Regeln) sowie deren Attribute im individuellen Zielstromkalkül eingeführt (nämlich Prädikate der Manipulationsfreiheit und Prädikate der Entscheidungsverbundenheit). Das Verhältnis der Institutionen zueinander wird im folgenden Abschnitt (3) anhand eines rechtlich geprägten und eines ökonomischen Systemverständnisses entwickelt. Es wird gezeigt, daß beide Systembegriffe auf einer Nichtadditivität der sie konstituierenden Institutionen gründen, die den qualitativen Vergleich unterschiedlicher Systeme erschweren; man überschätzt hingegen die Unterschiede zwischen juristischem und ökonomischem Systemverständnis: beide sind funktionsähnlich. Im letzten Hauptteil (4) werden schließlich vor dem Hintergrund einer gestaltenden Theorie die hierfür relevanten Teilbereiche (Sub-Systeme) der Rechnungslegungsordnung vorgestellt sowie einzelne Publizitätsnormen funktional ausgelegt. Der Beitrag schließt mit zusammenfassenden Thesen (5).

Mängel bei der Abschlußprüfung : Tatsachenberichte und Analysen aus betriebswirtschaftlicher Sicht
(2001)
Unternehmenskrisen, „überraschende“ zumal, standen am Anfang der gesetzlichen Normierung der Abschlußprüfung in Deutschland. Es entspricht daher einem legitimen Anliegen von Öffentlichkeit und Fachwelt, die herrschende Maßstäblichkeit der Qualität von Abschlußprüfungen und die Glaubwürdigkeit4 von Abschlußprüfern insbesondere dann in gesteigertem Maße als Problem zu begreifen, wenn den gesetzlichen Schutzzwecken und Schutznormen der etablierten Abschlußprüfung zum Trotz Unternehmen in eine Krise geraten: Denn innerhalb der institutionellen Mechanismen ihrer Früherkennung – eines funktionalen Teils des deutschen Systems von corporate governance – gilt die Pflichtprüfung mit Recht als pivotales Element. Vieles an festzustellender Kritik mag hierbei einem der Komplexität der zu verhandelnden Sachzusammenhänge unüberbrückbaren Laienverständnis geschuldet sein; manches aber ist sicherlich erklärlich durch verbesserbare gesetzliche Vorschriften, zu lösende theoretische (ökonomische und rechtswissenschaftliche) Problemstellungen und eine zu fördernde gute Berufspraxis. Jüngste fragliche Mängel der Abschlußprüfung geben den Anlaß zu vorliegenden Tatsachenberichten und betriebswirtschaftlichen Analysen. Die getroffene Auswahl der Unternehmen ist hierbei ebenso willkürlich wie die der betroffenen Wirtschaftsprüfungsgesellschaften – nicht zufällig ist indes die Auswahl der betriebswirtschaftlichen Grundprobleme: Betreffen diese doch wesentliche Erwartungen an die Abschlußprüfung, die offenbar so regelmäßig enttäuscht wurden, daß selbst in Regierungsbegründungen von Gesetzesvorlagen nunmehr eine „sog. Erwartungslücke“5 bemüht wird. Die Erwartungslücken ergeben sich hierbei insbesondere aus der Vorstellung, daß (a) der gesetzliche Pflichtprüfer bei einer ordnungsmäßigen Prüfung zwingend doloses Handeln aufzudecken habe, daß (b) bilanzielle Wertansätze hinreichend zuverlässige Größen bilden, die über die Vermögenslage des Unternehmens berichten und schließlich (c) die Prüfung der tatsächlichen wirtschaftlichen Lage des Unternehmens und die Unterrichtung hiervon in Prüfungsbericht und Bestätigungsvermerk eine Selbstverständlichkeit der Pflichtprüfung sei. Diesen Erwartungen folgt der Gang der Untersuchung.

During the last years the relationship between financial development and economic growth has received widespread attention in the literature on growth and development. This paper summarises in its first part the results of this research, stressing the growth-enhancing effects of an increased interpersonal re-allocation of resources promoted by financial development. The second part of the paper seeks to identify the determinants of financial development based on Diamond's theory of financial intermediation as delegated monitoring. The analysis shows that the quality of corporate governance of banks is the key factor in financial system development. Accordingly, financial sector reforms in developing countries will only succeed if they strengthen the corporate governance of financial institutions. In this area, financial institution building has an important contribution to make.

In den letzten Jahren wurden verschiedene Modelle entwickelt, um das Ausfallrisiko von Banken unter Berücksichtigung von Portfolioeffekten zu quantifizieren. Bisher hat sich kein Ansatz als allgemein akzeptierter Standard durchsetzen können. Da die Modelle grundlegende konzeptionelle Unterschiede aufweisen und unterschiedliche empirische Inputdaten verwenden, hat die Auswahl eines Kreditrisikomodells unter Umständen einen erheblichen Einfluß auf die Kreditportfoliosteuerung der Bank. In diesem Beitrag soll deshalb geklärt werden, ob die Modelle systematisch abweichende Value-at-Risk-Werte berechnen und worin die Ursachen für auftretende Abweichungen liegen. Zunächst wird gezeigt, daß die bestehenden Kreditrisikomodelle in zwei grundlegende Klassen eingeteilt werden können: Assetwert-basierte Modelle und auf Ausfallraten basierende Modelle. Am Beispiel eines Musterportfolios von Krediten an deutsche Baufirmen werden zwei Vertreter der Modellklassen (CreditMetrics und CreditRisk+) verglichen und der Effekt der unterschiedlichen empirischen Inputparameter auf die Risikoergebnisse abgeschätzt. Die Analyse zeigt erhebliche Unterschiede zwischen den Modellen. Eine Analyse der Abweichungsursachen ergibt allerdings, daß der Grund für die großen Value-at-Risk-Unterschiede in erster Linie in den unterschiedlichen empirischen Inputdaten liegt, welche zu unterschiedlichen impliziten Korrelationsannahmen führen. Es wird gezeigt, wie die Modellparameter gewählt werden müssen, um identische Korrelationen zu erzeugen. Bei konsistenten Korrelationsannahmen stimmen die Ergebnisse beider Modelle weitgehend überein. Keywords: Credit Risk Models, credit risk correlation

Motivated by the recent discussion of the declining importance of deposits as banks´ major source of funding we investigate which factors determine funding costs at local banks. Using a panel data set of more than 800 German local savings and cooperative banks for the period from 1998 to 2004 we show that funding costs are not only driven by the relative share of comparatively cheap deposits of bank´s liabilities but among other factors especially by the size of the bank. In our empirical analysis we find strong and robust evidence that, ceteris paribus, smaller banks exhibit lower funding costs than larger banks suggesting that small banks are able to attract deposits more cheaply than their larger counterparts. We argue that this is the case because smaller banks interact more personally with customers, operate in customers´ geographic proximity and have longer and stronger relationships than larger banks and, hence, are able to charge higher prices for their services. Our finding of a strong influence of bank size on funding costs is also in an in- ternational context of great interest as mergers among small local banks - the key driver of bank growth - are a recent phenomenon not only in European banking that is expected to continue in the future. At the same time, net interest income remains by far the most important source of revenue for most local banks, accounting for approximately 70% of total operating revenues in the case of German local banks. The influence of size on funding costs is of strong economic relevance: our results suggest that an increase in size by 50%, for example, from EUR 500 million in total assets to EUR 750 million (exemplary for M&A transactions among local banks) increases funding costs, ceteris paribus, by approximately 18 basis points which relates to approx. 7% of banks´ average net interest margin.

This paper is one of the first to analyse political influence on state-owned savings banks in a developed country with an established financial market: Germany. Combining a large dataset with financial and operating figures of all 457 German savings banks from 1994 to 2006 and information on over 1,250 local elections during this period we investigate the change in business behavior around elections. We find strong indications for political inflence: the probability that savings banks close branches, lay-off employees or engage in merger activities is significantly reduced around elections. At the same time they tend to increase their extraordinary spendings, which include support for social and cultural events in the area, on average by over 15%. Finally, we find that savings banks extend significantly more loans to their corporate and private customers in the run-up to an election. In further analyses, we show that the magnitude of political influence depends on bank specific, economical and political circumstances in the city or county: political influence seems to be facilitated by weak political majorities and profitable banks. Banks in economically weak areas seem to be less prone to political influence.

Im Rahmen des Value Based Managements sollen alle Manahmen der Unternehmensfhrung auf die Steigerung des intrinsischen Marktwertes des Eigenkapitals ausgerichtet werden.

In allen Anwendungsbereichen des VBM zeigt sich nämlich aus theoretischer Sicht die Problematik der Verwendung eines risikoangepassten Zinssatzes zur Berechnung von Kapitalkosten: Schon die Verwendung eines risikoangepassten Kapitalkostensatzes im Rahmen der Planung kann problematisch sein. Die Verwendung risikoangepasster Kapitalkosten als Benchmark bei der Performancemessung ist sogar ganz abzulehnen, und bei der Managemententlohnung ist die Verrechnung von risikoangepassten Kapitalkosten zwingend mit Fehlanreizen verbunden. Aber auch praxisübliche Modifikationen erweisen sich als problematisch, da Erfolgskomponenten nicht bzw. nicht vollständig berücksichtigt werden. Im Gegensatz zu herkömmlichen Konzepten weist das VBM-Konzept ERIC eine tatsächliche theoretische Fundierung auf. In Velthuis (2003c) werden grundlegende theoretische und praktische Anforderungen für die einzelnen Anwendungsbereiche herausgearbeitet und es wird gezeigt, dass ein integriertes VBM-Konzept auf Basis des Residualgewinns ERIC diese Anforderungen stets erfüllt. Ziel dieses Aufsatzes ist es, die Grundkonzeption von ERIC theoretisch weiter zu entwickeln. Während in Velthuis (2003c) stets von einer sehr einfachen Idealwelt ausgegangen wird, soll hier zum einen verdeutlicht werden, wie ein erfolgreiches Value Based Management auf Basis von ERIC in komplexeren und realitätsnäheren Situationen erfolgen kann. Zum anderen gilt es, zusätzliche praktische Problembereiche zu erkennen und Lösungsmöglichkeiten aufzuzeigen. Der Aufsatz ist wie folgt aufgebaut: Zunächst wird gezeigt, wie der Residualgewinn ERIC zu berechnen ist, und es wird ein Überblick über die Anwendungsbereiche gegeben. Anschließend wird die grundlegende Entscheidungssituation für die späteren Darstellungen erörtert und es werden fundamentale Prinzipien des Value Based Managements und ihre Bedeutung für die einzelnen Anwendungsbereichen erläutert. Sodann wird für die einzelnen Bereichen des Value Based Managements, der Planung, Performancemessung, Managemententlohnung und der Bereichssteuerung gezeigt, wie ERIC anzuwenden ist, damit eine tatsächliche Shareholder-Orientierung gewährleistet wird. Die Darstellungen erfolgen dabei jeweils zunächst vor dem Hintergrund einer Idealwelt. In einem zweiten Schritt wird die Entscheidungssituation jeweils modifiziert, um der Realität ein Stück näher zu kommen.

This paper analyses the long-term effects of improved small-scale lending, often provided by microfinance institutions set up with the support of development aid. The analysis shows that some common assumptions about microfinance are not true at all: First, it shows that the impact on income will accrue not to the microenterprises themselves, but rather to the consumers of their products. Second, microfinance will have a significant positive effect on the wage levels of employees in the informal sector. Third, microfinance will cause high growth rates in the informal production sector, whereas the trade sector will either contract or at best grow very little.

The theoretical derivation of credit market segmentation as the result of a free market process
(2003)
Information asymmetries make it difficult for banks to assess accurately whether specific entrepreneurs are able and/or willing to repay their loans. This leads to implicit interest rate ceilings, i.e. banks "refuse" to increase their interest rates beyond this ceiling as this would lower their net returns. Although the maximum interest rate increases as the size of enterprises decreases, such ceilings nonetheless constrain the banks’ ability to set interest rates at a level that would enable them to cover costs. If transaction costs are high, the total costs associated with granting small and medium-sized loans will exceed the maximum average return which the banks can earn by issuing such loans. For this reason, banks do not lend to small and medium-sized enterprises, and, as a consequence, these businesses have no access to formal sector loans. Because micro and small enterprises have a very high RoI, it is worthwhile for them to rely on expensive informal loans to finance their operations, at least until they reach a certain size. Once they have reached this size, however, it does not make economic sense for them to continue taking out informal credits, and thus they face a growth constraint imposed by the credit market. Medium-sized enterprises earn a lower RoI than small ones, which is why borrowing in the informal credit market is not a worthwhile option for them. Moreover, they do not have access to credit from formal financial institutions, and are thus excluded from obtaining any kind of financing in either of the two credit markets. As the result of free, unregulated market forces we get a stable equilibrium in which the credit market is segmented into an informal (small loan) segment, a formal (large loan) segment and, in between, a "non-market" (medium loan) segment.

The extension of long-term loans, e.g. to finance housing, is adversely affected by inflation. For one thing, the higher nominal interest rates charged by the banks in response to inflation mean that borrowers have to make (nominally) higher interest payments, which unnecessarily reduces their borrowing capacity. For another, long-term loans with variable interest rates increase the probability that borrowers will become unable to meet their payment obligations. The present paper examines these two assertions in detail. At the same time, it presents a concept for substantially reducing the weaknesses of conventional lending methodologies. We start by investigating the consequences of a stable inflation rate on the borrowing capacity of credit clients, then go on to analyze the impact of fluctuating inflation rates on the risk of default.

Die externe Performance-Messung beurteilt auf Basis öffentlich verfügbarer Daten die Leistung des Fondsmanagements. Es wird zunächst geprüft, inwieweit die für die Beurteilung von Aktienfonds entwickelten Maße auf Rentenfonds anwendbar sind. Anschließend wird die Performance einer Stichprobe deutscher Rentenfonds untersucht. Es zeigt sich, daß die risikoadjustierte Rendite in den meisten Fällen nicht über der eines geeigneten Marktindex liegt. Einige Fonds weisen ein signifikantes Aktien-Exposure auf. Ein systematischer Zusammenhang zwischen der Nettorendite und der Gebührenhöhe kann nicht nachgewiesen werden.

Die mit unterschiedlichen Organisationsformen des Wertpapierhandels einhergehende Liquidität und ihre Messung ist eine der zentralen Fragen im Zusammenhang mit der Gestaltung von Wertpapiermärkten. Zunächst wird die Eignung verschiedener in der Literatur vorgeschlagener Liquiditätsmaße diskutiert. Anhand einer Serie von Marktexperimenten wird dann die Liquidität der grundsätzlichen Ausgestaltungsformen des Wertpapierhandels - Gesamtkursermittlung, kontinuierliche Auktion und Market-Maker-System - miteinander verglichen.
Sowohl das Handelsvolumen als auch das von ROLL (1984) vorgeschlagene Maß sind offenbar für den Vergleich der Liquidität unterschiedlich organisierter Wertpapiermärkte nicht geeignet. Eine aufgrund theoretischer Überlegungen prognostizierte Überschätzung der Transaktionskosten bei der Gesamtkursermittlung kann empirisch bestätigt werden.
Die explizite Geld-Brief-Spanne ist dagegen grundsätzlich ein geeignetes Liquiditätsmaß. Mit den Daten der experimentellen Märkte läßt sich auch für die Gesamtkursermittlung eine solche Spanne ermitteln. Sie erweist sich als niedriger als die Spanne in der kontinuierlichen Auktion und dem Market-Maker-Markt. Jedoch ist auch die Geld-Brief-Spanne mit Vorsicht zu interpretieren. Es wird gezeigt, daß unter bestimmten Umständen systematische Verzerrungen existieren können. In den hier untersuchten experimentellen Märkten ließen sich diese identifizieren. Bei Untersuchungen anhand von Felddaten ist dies jedoch nicht ohne weiteres möglich, so daß hier die Gefahr von Verzerrungen durchaus real ist.

Der Neue Markt soll wachstumsorientierten Unternehmen den Zugang zur Börse eröffnen. Die für dieses Marktsegment neu geschaffene Institution des Betreuers soll Vorbildcharakter für andere Marktsegmente haben. In der vorliegenden Arbeit werden Vor- und Nachteile des Betreuer-Konzeptes erarbeitet. Die daraus abgeleiteten Fragen werden empirisch untersucht. Dabei zeigt sich, daß der Neue Markt eine hohe Handelsintensität und niedrige Geld-BriefSpannen aufweist. Auch eine schriftliche Befragung der notierten Unternehmen ergab eine positive Einschätzung des neuen Marktsegments.
Überlegungen zur Profitabilität der Betreuer-Funktion deuten darauf hin, daß diese nicht an sich profitabel ist. Es findet offenbar eine Quersubventionierung aus Erträgen des Emissionsgeschäftes statt. Diese Abhängigkeit sollte berücksichtigt werden, wenn die Übertragung des Betreuerkonzepts auf andere Marktsegmente diskutiert wird.

Joseph E. Stiglitz (1943 - )
(2000)
Am 24.11.1999 gibt Joseph E. Stiglitz seinen vorzeitigen Rücktritt als Chief Economist und Senior Vice President der Weltbank zum Jahresende bekannt. Er will sich wieder ausschließlich der Forschung und Lehre widmen und kehrt auf seinen Lehrstuhl am Economics Department der Stanford University zurück. Stiglitzs Rückzug aus der aktiven Entwicklungspolitik erfolgt nicht ganz freiwillig. Er selbst kommentiert seinen Entschluß: „It has become obvious to me that it would be difficult to continue to speak out as forcefully and publicly as I have on a variety of issues and still remain as chief economist. Rather than muzzle myself, or be muzzled, I decided to leave.“ (New York Times, 1.12.1999). Seit geraumer Zeit galt seine öffentliche Kritik am Washington Consensus, dem ökonomischen Glaubensbekenntnis, auf das sich die politische Linie des US Treasury genauso stützt wie die Stabilisierungs- und Reformpolitik des IWF, als Dorn im Auge der Vertreter dieser Institutionen. Für sie war Stiglitz - so die Metapher der Financial Times vom 26.11.99 - „a veritable gadfly“, eine wahre Viehbremse, deren lästiges Summen aufgrund von Position und Intellekt nicht einfach ignoriert werden konnte. ...

We present an empirical study focusing on the estimation of a fundamental multi-factor model for a universe of European stocks. Following the approach of the BARRA model, we have adopted a cross-sectional methodology. The proportion of explained variance ranges from 7.3% to 66.3% in the weekly regressions with a mean of 32.9%. For the individual factors we give the percentage of the weeks when they yielded statistically significant influence on stock returns. The best explanatory power – apart from the dominant country factors – was found among the statistical constructs „success“ and „variability in markets“.

In der Literatur zur Abschlußprüfung ist ein negativer Effekt eines ökonomischen Vorteils aus der wiederholten Mandatsannahme, der aufgrund von Transaktionskosten entsteht, auf die Unabhängigkeit des Abschlußprüfers diskutiert worden. Anders als die bisher vorgestellten Ansätze wird im Rahmen des vorliegenden Modells rationales Verhalten der Kapitalmarktakteure unterstellt, die ihre Ansprüche in Abhängigkeit der Reputation des Prüfers und damit der Glaubwürdigkeit des Testats stellen. Als Ergebnis kann festgehalten werden, daß transaktionskostenbedingte Quasirenten die Urteilsfreiheit nicht gefährden, sondern daß vielmehr Informationsrenten für das Berichtsverhalten des Prüfers ausschlaggebend sind. Auch ergeben sich neue Ansatzpunkte zur Diskussion der externen Pflichtrotation und von Maßnahmen zur Steigerung der Kapitalmarkteffizienz.

The objective of this paper is to test the hypothesis that in particular financially constrained firms lease a higher share of their assets to mitigate problems of asymmetric information. The assumptions are tested under a GMM framework which simultaneously controls for endogeneity problems and firms’ fixed effects. We find that the share of total annual lease expenses attributable to either finance or operating leases is considerably higher for financially strained as well as for small and fast-growing firms – those likely to face higher agency-cost premiums on marginal financing. Furthermore, our results confirm the substitution of leasing and debt financing for lessee firms. However, we find no evidence that firms use leasing as an instrument to reduce their tax burdens. Keywords: Leasing; financial constraints; capital structure; asymmetric information.

Despite a lot of re-structuring and many innovations in recent years, the securities transaction industry in the European Union is still a highly inefficient and inconsistently configured system for cross-border transactions. This paper analyzes the functions performed, the institutions involved and the parameters concerned that shape market and ownership structure in the industry. Of particular interest are microeconomic incentives of the main players that can be in contradiction to social welfare. We develop a framework and analyze three consistent systems for the securities transaction industry in the EU that offer superior efficiency than the current, inefficient arrangement. Some policy advice is given to select the 'best' system for the Single European Financial Market.

Efficient systems for the securities transaction industry : a framework for the European Union
(2003)
This paper provides a framework for the securities transaction industry in the EU to understand the functions performed, the institutions involved and the parameters concerned that shape market and ownership structure. Of particular interest are microeconomic incentives of the industry players that can be in contradiction to social welfare. We evaluate the three functions and the strategic parameters - the boundary decision, the communication standard employed and the governance implemented - along the lines of three efficiency concepts. By structuring the main factors that influence these concepts and by describing the underlying trade-offs among them, we provide insight into a highly complex industry. Applying our framework, the paper describes and analyzes three consistent systems for the securities transaction industry. We point out that one of the systems, denoted as 'contestable monopolies', demonstrates a superior overall efficiency while it might be the most sensitive in terms of configuration accuracy and thus difficult to achieve and sustain.

Academic contributions on the demutualization of stock exchanges so far have been predominantly devoted to social welfare issues, whereas there is scarce empirical literature referring to the impact of a governance change on the exchange itself. While there is consensus that the case for demutualization is predominantly driven by the need to improve the exchange's competitiveness in a changing business environment, it remains unclear how different governance regimes actually affect stock exchange performance. Some authors propose that a public listing is the best suited governance arrangement to improve an exchange's competitiveness. By employing a panel data set of 28 stock exchanges for the years 1999-2003 we seek to shed light on this topic by comparing the efficiency and productivity of exchanges with differing governance arrangements. For this purpose we calculate in a first step individual efficiency and productivity values via DEA. In a second step we regress the derived values against variables that - amongst others - map the institutional arrangement of the exchanges in order to determine efficiency and productivity differences between (1) mutuals (2) demutualized but customer-owned exchanges and (3) publicly listed and thus at least partly outsider-owned exchanges. We find evidence that demutualized exchanges exhibit higher technical efficiency than mutuals. However, they perform relatively poor as far as productivity growth is concerned. Furthermore, we find no evidence that publicly listed exchanges possess higher efficiency and productivity values than demutualized exchanges with a customer-dominated structure. We conclude that the merits of outside ownership lie possibly in other areas such as solving conflicts of interest between too heterogeneous members.

In recent years stock exchanges have been increasingly diversifying their operations into related business areas such as derivatives trading, post-trading services and software sales. This trend can be observed most notably among profit-oriented trading venues. While the pursuit for diversification is likely to be driven by the attractiveness of these investment opportunities, it is yet an open question whether certain integration activities are also efficient, both from a social welfare and from the exchanges' perspective. Academic contributions so far analyzed different business models primarily from the social welfare perspective, whereas there is only little literature considering their impact on the exchange itself. By employing a panel data set of 28 stock exchanges for the years 1999-2003 we seek to shed light on this topic by comparing the factor productivity of exchanges with different business models. Our findings suggest three conclusions: (1) Integration activity comes at the cost of increased operational complexity which in some cases outweigh the potential synergies between related activities and therefore leads to technical inefficiencies and lower productivity growth. (2) We find no evidence that vertical integration is more efficient and productive than other business models. This finding could contribute to the ongoing discussion about the merits of vertical integration from a social welfare perspective. (3) The existence of a strong in-house IT-competence seems to be beneficial to overcome.

One of the most acute problems in the world today is provision of a respectable living for the elderly. Today the process of aging population (as a result of a declined birth rate and increased life expectancy) has touched all countries of the world - developed countries as well as countries like Russia. Consequently, reforming traditional pension systems to deal with the changing situation has become an important issue around the world. These reforms typically center on the implementation of some form of funding of future pension benefits. This also holds for Russia, where in 1995 pension reform legislation introduced the so-called “accumulation pension”. In this context, this article will deal with the issues concerning the establishment of mutual funds, legal aspects of their operating and their investing opportunities. There will be carried out a comparative analysis of mutual funds with the other forms of public investments, namely: Common Funds of Bank Management, Voucher Investment Funds and Joint-stock Investment Funds.

Both banks and open end real estate funds effectuate liquidity transformation in large amounts and high scales. Because of this similarity the latter should be analyzed using the same methodologies as usually applied for banks. We show that the work in the tradition of Diamond and Dybvig (1983), especially Allen and Gale (1998) and Diamond and Rajan (2001), provides an applicable theoretical framework. We used this as the basis for our model for open end real estate funds. We then examined the usefulness of the modeling structure in analyzing open end real estate funds. First, we could show that withdrawing of capital resulting in a run is not always inefficient. Instead, withdrawing can as well be referred to the situation where the low return of an open end fund unit in comparison to other opportunities makes, (partial) withdrawal viewed from the risk-sharing perspective optimal. Even with costly liquidation, this result will hold, though we will have deadweight losses in such a situation. Second, introducing a secondary market in our model does, not in general, resolve the problem of deadweight losses associated with foreclosure. If assets are sold during a run, we do not only have a transfer of value but it can also create an economic cost. Because funds are forced to liquidate the illiquid asset in order to fulfill their obligations, the price of the real estate asset is forced down making the crisis worse. Rather than providing insurance, such that investors receive a transfer in negative outcomes, the secondary market does the opposite. It provides a negative insurance instead. Third, our model proves that the open end structure provides a monitoring function which serves as an efficient instrument to discipline the funds management. Therefore, we argue that an open end structure can represent a more adequate solution to securitize real estate or other illiquid assets. Instead of transforming open end in closed end structures, fund runs should be accepted as a normal phenomenon to clear the market from funds with mismanagement.

In the early 1990s, a consensus emerged among the leading experts in the field of small and micro business finance. It is based on three elements: The focus of projects should be on improving the entire financial sector of a given developing country; a commercial approach should be adopted, which implies covering costs and keeping costs as low as possible; and institutions should be created which are both able and willing to provide good financial services to the target group on a lasting basis. The starting point for this paper, which wholeheartedly endorses these three elements, is the proposition that putting these general principles into practice is much more difficult than some of their proponents seem to believe - and also more difficult than some of them have led donors to believe. The paper discusses the central issues of small and micro business financing in three areas: credit in general and the cost-effectiveness of lending methodologies in particular (Section II); savings in general and the role of deposit-taking in the growth of a target group-oriented financial institution in particular (Section III); and the process of creating viable target group-oriented financial institutions in developing countries (Section IV). We argue that donor institutions must be willing, and prepared, to play a role here which differs in important respects from their conventional role if they really wish to support sustainable financial sector development.

Financial development and financial institution building are important prerequisites for economic growth. However, both the potential and the problems of institution building are still vastly underestimated by those who design and fund institution building projects. The paper first underlines the importance of financial development for economic growth, then describes the main elements of “serious” institution building: the lending technology, the methodological approaches, and the question of internal structure and corporate governance. Finally, it discusses three problems which institution building efforts have to cope with: inappropriate expectations on the part of donor and partner institutions regarding the problems and effects of institution building efforts, the lack of awareness of the importance of governance and ownership issues, and financial regulation that is too restrictive for microfinance operations. All three problems together explain why there are so few successful micro and small business institutions operating worldwide.

Der folgende Beitrag geht der Frage nach, wie die Verteilung von Entscheidungs- und Handlungsrechten in Unternehmen im Rahmen der Corporate Governance ausgestaltet werden kann. Im Zentrum der Überlegungen steht die Frage, welcher der am Unternehmen beteiligten Interessengruppen diese Rechte sinnvollerweise zukommen sollten. Insbesondere die beiden polaren Systeme - das auf dem Shareholder-Value-Primat aufbauende System einer ausschließlich im Interesse der Aktionäre geführten Unternehmung auf der eine Seite - und einem Corporate Governance-System, das die Interessen aller am Unternehmen beteiligten Stakeholder berücksichtigt, auf der anderen Seite - werden geschildert und mit den Mitteln der ökonomischen Theorie bewertet. Spezifische Investitionen möglicher Stakeholder und die Institutionen und Mechanismen, die eine Absicherung der daraus entstehenden ökonomischen Renten für die jeweiligen Stakeholder erlauben, sind damit wichtige Bestimmungsparameter für die Unternehmensverfassung. Insbesondere die Existenz und Güte von Märkten innerhalb des Finanzsystems, in dem ein Unternehmen tätig ist, lassen das ein oder das andere Corporate Governance-System vorteilhafter erscheinen. Überlegungen zu anderen möglichen Mechanismen, die auf der internen Organisation von Unternehmungen basieren und dadurch eine Feinsteuerung von Entscheidungs- und Handlungsrechten - und der damit verbundenen Machtverteilung zwischen den Interessengruppen im Unternehmen - erlaubt, schließen die Arbeit ab.

The paper is a follow-up to an article published in Technique Financière et Developpement in 2000 (see the appendix to the hardcopy version), which portrayed the first results of a new strategy in the field of development finance implemented in South-East Europe. This strategy consists in creating microfinance banks as greenfield investments, that is, of building up new banks which specialise in providing credit and other financial services to micro and small enterprises, instead of transforming existing credit-granting NGOs into formal banks, which had been the dominant approach in the 1990s. The present paper shows that this strategy has, in the course of the last five years, led to the emergence of a network of microfinance banks operating in several parts of the world. After discussing why financial sector development is a crucial determinant of general social and economic development and contrasting the new strategy to former approaches in the area of development finance, the paper provides information about the shareholder composition and the investment portfolio of what is at present the world's largest and most successful network of microfinance banks. This network is a good example of a well-functioning "private public partnership". The paper then provides performance figures and discusses why the creation of such a network seems to be a particularly promising approach to the creation of financially self-sustaining financial institutions with a clear developmental objective.

At present, the question of how national pension or retirement payment systems should be organised is being hotly debated in various countries, and opinions vary widely as to what should be regarded as the optimal design for such systems. It appears to the authors of the present paper that in this entire discussion one aspect is largely overlooked: What relationships exist between the pension system and the financial system in a given country? As such relationships might prove to be important, the present paper investigates the following questions: (1) Are there differences between the national pension systems of three major European countries – Germany, France and the U.K. – and between the financial systems of these countries? (2) And if the existence of such differences can be demonstrated, is there a correspondence between the differences with respect to the various national pension systems and the differences as regards the countries’ financial systems? (3) And if such a correspondence exists, is there any kind of interrelationship between the national financial and pension systems of the individual countries which goes beyond a mere correspondence? Looking mainly at two aspects – namely, risk allocation and the incentives to create human capital – the authors of this paper argue (1) that there are indeed considerable differences between the financial and pension systems of the three countries; (2) that in both Germany and the U.K. there are also systematic correspondences between the respective pension systems and financial systems and their economic characteristics, but that such a correspondence cannot be identified in the case of France; and (3) that these parallels are, in the final analysis, based on complementarities and are therefore likely to contribute to the efficiency of the German and the British systems. The paper concludes with a brief look at policy implications which the existence of, or the lack of, consistency between national pension systems and national financial systems might have.

What constitutes a financial system in general and the German financial system in particular?
(2003)
This paper is one of the two introductory chapters of the book "The German Financial System". It first discusses two issues that have a general bearing on the entire book, and then provides a broad overview of the German financial system. The first general issue is that of clarifying what we mean by the key term "financial system" and, based on this definition, of showing why the financial system of a country is important and what it might be important for. Obviously, a definition of its subject matter and an explanation of its importance are required at the outset of any book. As we will explain in Section II, we use the term "financial system" in a broad sense which sets it clearly apart from the narrower concept of the "financial sector". The second general issue is that of how financial systems are described and analysed. Obviously, the definition of the object of analysis and the method by which the object is to be analysed are closely related to one another. The remainder of the paper provides a general overview of the German financial system. In addition, it is intended to provide a first indication of how the elements of the German financial system are related to each other, and thus to support our claim from Section II that there is indeed some merit in emphasising the systemic features of financial systems in general and of the German financial system in particular. The chapter concludes by briefly comparing the general characteristics of the German financial system with those of the financial systems of other advanced industrial countries, and taking a brief look at recent developments which might undermine the "systemic" character of the German financial system.

We investigate the connection between corporate governance system configurations and the role of intermediaries in the respective systems from a informational perspective. Building on the economics of information we show that it is meaningful to distinguish between internalisation and externalisation as two fundamentally different ways of dealing with information in corporate governance systems. This lays the groundwork for a description of two types of corporate governance systems, i.e. insider control system and outsider control system, in which we focus on the distinctive role of intermediaries in the production and use of information. It will be argued that internalisation is the prevailing mode of information processing in insider control system while externalisation dominates in outsider control system. We also discuss shortly the interrelations between the prevailing corporate governance system and types of activities or industry structures supported.

Pensions- und Finanzsysteme in Europa : ein Vergleich unter dem Gesichtspunkt der Komplementarität
(2001)
Die Debatte über die optimale Ausgestaltung der Alterssicherung wird in jüngster Zeit äußerst kontrovers und hitzig geführt. Dabei scheint uns ein zentraler Aspekt nicht genügend beachte zu werden: Welcher Zusammenhang besteht zwischen den Merkmalen des Finanzsystems und des Pensionssystems eines Landes? Weil dieser Zusammenhang wichtig sein könnte, wird in diesem Beitrag untersucht, ob es Unterschiede zwischen den Finanz- und Pensionssystemen in drei großen europäischen Ländern, Deutschland, Frankreich und Großbritannien, gibt, ob sich diese Unterschiede in charakteristischer Weise entsprechen und ob sich über diese Entsprechungen hinaus auch Wechselwirkungen zwischen dem Finanzsystem und dem Pensionssystem eines Landes nachweisen lassen.
Zur Beantwortung dieser Fragen wird in einem ersten Schritt kurz die Unterschiedlichkeit der Finanz- und Pensionssysteme zwischen den drei Ländern skizziert, und es werden parallelen zwischen diesen Unterschieden nachgewiesen. Daran anschließend werden die Zusammenhänge zwischen der Ausgestaltung der gesetzlichen Alterssicherung und der volkswirtschaftlichen Risikoallokation sowie der Ausgestaltung der betrieblichen Alterssicherung für die Unternehmensstrategien, -finanzierung und –verfassung betrachtet. Dabei lässt sich zeigen, dass es sowohl in Deutschland als auch in Großbritannien eine – wenn auch vollkommen unterschiedlich ausgeprägte – Komplementarität zwischen Finanz- und Pensionssystem gibt, während sich ein solcher Zusammenhang für Frankreich nicht konstatieren lässt. Abschließend werden wirtschaftspolitische Implikationen dieses Zusammenhangs angesprochen

Access to loans and other financial services is extremely valuable for micro-, small- and medium-sized enterprises in developing and transition countries as it enables their owners as well as their employees to exploit their economic potential and to increase their income. Although this insight has lead development aid institutions to undertake many attempts to create sustainable microfinance institutions, only a small fraction of these has been successful so far. This article analyses what determines the success of attempts to provide financial services in general, and credit in particular, to low income target groups in these countries. We argue that it is crucial to understand, and to mitigate or even eliminate in practice, the serious and numerous incentive problems at the level of the lending operations as well as those at the levels of the human resource management and the governance of microfinance institutions. We attempt to show moreover, that unsolved incentive problems at only one level will ultimately undermine any potential success at the other levels. In our paper, we first analyse information and incentive problems from a theoretical perspective, using and extending the well-known Stiglitz-Weiss model of credit rationing, and derive theoretical requirements for solutions of these problems. In the light of these considerations, we then discuss how problems are solved in practice. Section 3 deals with the credit relationship. Section 4 extends the argument by showing how incentive problems within the institution can be handled, and section 5 analyses corporate governance-related problems of development finance institutions as incentive problems. In section 6 it is demonstrated why, and how, the incentive problems at the different levels, as well as their solutions, are interrelated. From this we derive the proposition that, as the institutional devices for dealing with these problems constitute a complementary system, any sustainable solution requires consistent arrangements of all elements and at all levels of the system. In the last section we will show the potential of strategic networks to set up institutions which we consider to be consistent systems for successfully solving the problems at all three levels simultaneously.

Während sich die Entwicklungsfinanzierung in Theorie und Praxis generell mit dem Finanzwesen in Entwicklungs- und Transformationsländern befasst, steht im Teilgebiet der Microfinance die Frage im Vordergrund, wie in diesen Ländern der Zugang ärmerer Bevölkerungsgruppen und speziell von Klein- und Kleinstunternehmer(innen), Kleinbauern und sonstigen wirtschaftlich Selbständigen aus eher niedrigen sozialen Schichten zu Kredit und anderen Finanzdiensleistungen verbessert werden kann. Obwohl es einige Vorläufer gibt, die schon früh die allgemeine Politik der Entwicklungsländer bezüglich ihrer Finanzsektoren und ebenso die dazu passende Entwicklungshilfe-Politik der Industrieländer der 60er und 70er Jahre mit ökonomisch-theoretischen Argumenten scharf kritisiert haben,1 waren in der Vergangenheit weder Entwicklungsfinanzierung im allgemeinen noch Microfinance im besonderen ein wirklich ernst genommener Gegenstand der ökonomischen Literatur, die man zum mainstream rechnen kann. Dem entspricht es, dass sich auch die Praxis der Entwicklungsfinanzierung sehr lange weitgehend unabhängig von ökonomisch- theoretischen Überlegungen vollzogen hat. Diese Situation hat sich seit mehr als einem Jahrzehnt grundlegend verändert. Dies hat einen wesentlichen Grund darin, dass sich in der entwicklungspolitischen Praxis auf dem Gebiet der Finanzierung von Klein- und Kleinstbetrieben, eben Microfinance, Erfolge erzielen ließen, die vorher unvorstellbar waren. Mit einer deutlichen commercial orientation und einer Ausrichtung auf die genuinen Probleme des financial institution building konnte erreicht werden, dass es inzwischen einige Dutzend Finanzinstitutionen in Entwicklungs- und Transformationsländern gibt, die ökonomisch stabil und sogar profitabel sind und mit ihrem Leistungsangebot eine große Anzahl von "armen" Kunden erreichen, die bei den Kreditabteilungen der herkömmlichen Banken kaum über die Schwelle gelassen würden.2 Dies hat die Aufmerksamkeit von Forschern aus dem mainstream erweckt. Mindestens ebenso wichtig sind aber die immanenten Entwicklungen innerhalb der ökonomischen Theorie. Mit ihrer Hinwendung zum institutionalistischen Denkansatz hat die Wirtschaftstheorie auf einmal eine neue Aufmerksamkeit für die Phänomene entwickelt, die für die Praktiker der Entwicklungsfinanzierung seit langem von zentraler Bedeutung sind: Inzwischen kann man theoretisch nachweisen, dass es in der Tat Zugangsprobleme zu Kredit für "kleine Leute" gibt, dass das Angebot von Kredit für sie beschränkt ist und dass es nicht genügt, einfach nur staatlich auferlegte Restriktionen – die so genannte financial repression – zu beseitigen, um ....

In a series of recent papers, Mark Roe and Lucian Bebchuk have developed further the concept of path dependence, combined it with concepts of evolution and used it to challenge the wide-spread view that the corporate governance systems of the major advanced economies are likely to converge towards the economically best system at a rapid pace. The present paper shares this skepticism, but adds several aspects which strengthen the point made by Roe and Bebchuk. The present paper argues that it is important for the topic under discussion to distinguish clearly between two arguments which can explain path dependence. One of them is based on the role of adjustment costs, and the other one uses concepts borrowed from evolutionary biology. Making this distinction is important because the two concepts of path dependence have different implications for the issue of rapid convergence to the best system. In addition, we introduce a formal concept of complementarity and demonstrate that national corporate governance systems are usefully regarded as – possibly consistent – systems of complementary elements. Complementarity is a reason for path dependence which supports the socio-biological argument. The dynamic properties of systems composed of complementary elements are such that a rapid convergence towards a universally best corporate governance systems is not likely to happen. We then proceed by showing for the case of corporate governance systems shaped by complementarity, that there even is the possibility of a convergence towards a common system which is economically inferior. And in the specific case of European integration, "inefficient convergence" of corporate governance systems is a possible future course of events.

Nationale rechtliche Rahmenbedingungen beeinflussen die Möglichkeiten für wirtschaftliche Aktivitäten multinationaler Unternehmen (MNU) in einem Gastland und der Koordination zwischen den Unternehmensteilen in verschiedenen Ländern. Sie sind damit wichtige Bestimmungsfaktoren für Standortentscheidungen von MNU. Die Bedeutung von Recht und Standortwahl unterscheidet sich aber je nach verfolgter MNUStrategie. Seit etwa 10 Jahren verändern MNU ihre strategische Ausrichtung. Gleichzeitig gab es wesentliche Fortschritte bei der Forschung über Geschäftsfeld- und Gesamt-unternehmensstrategien von MNU. Aufbauend auf diesen beiden Entwicklungen wird in diesem Aufsatz die These vertreten, daß heute - im Zeitalter integrierter MNU-Strategien - Einfachheit, Flexibilität und Verläßlichkeit des relevanten nationalen Rechts in einem Land und seine Ähnlichkeiten mit dem Recht anderer Länder eine zentrale Bedeutung erlangt haben. Dies stellt einen wesentlichen Unterschied zu einer – allerdings noch nicht gänzlich überwundenen – Situation dar, in der MNU mehr an einer rechtlichen Situation interessiert sind, die ihnen eine maximale Anpassung an die jeweiligen lokalen Umstände der einzelnen Gastländer erlaubt, worin der Kern von ”multi-domestic” MNU-Strategien besteht. Die Veränderung von MNU-Strategien bietet auch eine Erklärung für die in jüngster Zeit zu beobachtende Veränderung der Lobbyingaktivitäten von MNU bezüglich der rechtlichen Rahmenbedingungen in ihren jeweiligen Gastländern.

Die Empfehlung, das Shareholder-Value-Konzept zur Grundlage der Unternehmenspolitik zu machen, erscheint um so überzeugender und wird vermutlich um so eher akzeptiert, (1) je lohnender die Shareholder-Value-Orientierung für die Aktionäre ist, (2) je eindeutiger es ist, wie die Empfehlung umgesetzt werden kann und soll, und (3) je problemloser sie aus theoretischen und wohlfahrtsökonomischer Sicht ist. Der Beitrag diskutiert die in Wissenschaft und Praxis verbreiteten Positionen zu diesen drei Aspekten und erläutert, warum sie bzw. die emprischen, praktischen und theoretischen Argumente, durch die sie gestützt werden sollen, auf Mißverständnissen beruhen.

Since the beginning of the 1990s, it has been widely expected that the implementation of the European Single Market would lead to a rapid convergence of Europe’s financial systems. In the present paper we will show that at least in the period prior to the introduction of the common currency this expected convergence did not materialise. Our empirical studies on the significance of various institutions within the financial sectors, on the financing patterns of firms in various countries and on the predominant mechanisms of corporate governance, which are summarised and placed in a broader context in this paper, point to few, if any, signs of a convergence at a fundamental or structural level between the German, British and French financial systems. The German financial system continues to appear to be bank-dominated, while the British system still appears to be capital market-dominated. During the period covered by the research, i.e. 1980 – 1998, the French system underwent the most far-reaching changes, and today it is difficult to classify. In our opinion, these findings can be attributed to the effects of strong path dependencies, which are in turn an outgrowth of relationships of complementarity between the individual system components. Projecting what we have observed into the future, the results of our research indicate that one of two alternative paths of development is most likely to materialise: either the differences between the national financial systems will persist, or – possibly as a result of systemic crises – one financial system type will become the dominant model internationally. And if this second path emerges, the Anglo-American, capital market-dominated system could turn out to be the “winner”, because it is better able to withstand and weather crises, but not necessarily because it is more efficient.

The paper presents an empirical analysis of the alledged transformation of the financial systems in the three major European economies, France, Germany and the UK. Based on a unified data set developed on the basis of national accounts statistics, and employing a new and consistent method of measurement, the following questions are addressed: Is there a common pattern of structural change; do banks lose importance in the process of change; and are the three financial systems becoming more similar? We find that there is neither a general trend towards disintermediation, nor towards a transformation from bank-based to capital market-based financial systems, nor for a loss of importance of banks. Only in the case of France strong signs of transformation as well as signs of a general decline in the role of banks could be found. Thus the three financial systems also do not seem to become more similar. However, there is also a common pattern of change: the intermediation chains are lengthening in all three countries. Nonbank financial intermediaries are taking over a more important role as mobilizers of capital from the non-financial sectors. In combination with the trend towards securitization of bank liabilites, this change increases the funding costs of banks and may put banks under pressure. In the case of France, this change is so pronounced that it might even threaten the stability of the financial system.

Die durch jahrzehntelange Planwirtschaft geprägten Strukturen sind in Russland noch fest verwurzelt. Dementsprechend ist das Bankensystem auch zwölf Jahre nach dem Ende des kommunistischen Regimes unterentwickelt. Die markantesten Merkmale der Finanzwirtschaft sind die ungewöhnliche Größenstruktur der Banken; deren Schwierigkeiten, die rapide zunehmende Zahl kleinster, kleiner und mittlerer Unternehmen mit Finanzdienstleistungen zu versorgen sowie die geringe Rolle ausländischer Banken. Überdies sind die weiterhin bestehenden Systemrisiken nicht zu unterschätzen.

Wenn man untersuchen möchte, ob sich die Finanzsysteme verschiedener Länder im Verlauf der letzten Jahre aneinander angeglichen haben oder demnächst angleichen werden, braucht man ein Konzept zur Beschreibung von Finanzsystemen, durch das wesentliche Strukturen, deren Unterschiede und Veränderungen erkennbar werden, ohne dabei in "Systemgeschwafel" (D. Schneider) abzugleiten. Wir haben dafür das Konzept der Komplementarität als nützlich identifiziert. Der Beitrag stellt dieses Konzept vor und soll und seine Eignung belegen. Letztlich geht es dabei auch um die Frage, ob reale Finanzsysteme konsistente Systeme mit komplementären Elementen darstellen. Nach der Vorstellung der formalen Konzepte der Komplementarität und der Konsistenz wird "das Finanzsystem" auf seine Komple mentarität untersucht. Dazu wird ein Finanzsystem aus der Sicht von Unternehmen des nichtfinanziellen Sektors als ein System gekennzeichnet, das aus drei Teilsystemen besteht. Das erste Teilsystem ist das Finanzierungssystem einschließlich Finanzsektor und Mustern der Unternehmensfinanzierung, das zweite das Corporate Governance-System und das dritte das Unternehmens-Strategie-System. Für alle drei Teilsysteme wird – allgemein und mit Bezug auf die Finanzsysteme Deutschlands, Japans und der USA - gezeigt, inwieweit die Elemente der betreffenden Teilsysteme untereinander komplementär sind, und geprüft, ob sie in ihren Ausprägungen auch konsistent sind, d.h. wirklich "zueinander passen". Untersucht wird auch die Komplementarität und Konsistenz zwischen den Teilsystemen selbst. Der Beitrag endet mit Überlegungen über die Anwendung des Komplementaritätskonzepts. Dass ein Finanzsystem die Eigenschaft der Komplementarität aufweist, hat nicht nur weitreichende Implikationen für die Methodik der Analyse von Finanzsystemen, sondern auch für die Vorhersehbarkeit der Entwicklung von Finanzsystemen und damit für die Wahrscheinlichkeit einer Konvergenz von Finanzsystemen, für deren Effizienzeigenschaften und für die Möglichkeiten, Finanzsysteme durch gestaltende Eingriffe zu verbessern.

„Bedeutende Finanzplätze“ oder Finanzzentren sind eng abgegrenzte Orte mit einer beträchtlichen Konzentration wichtiger professioneller Aktivitäten aus dem Finanzdienstleistungsbereich und der entsprechenden Institutionen. Allerdings: „Finance is a footloose industry“: Die Finanzbranche kann abwandern, ein Finanzzentrum kann sich verlagern, möglicherweise auch einfach auflösen. Die Möglichkeit der Auflösung und der Abwanderung stellt eine Bedrohung dar, die in der Zeit der Globalisierung und der rasanten Fortschritte der Transport- und der Informations- und Kommunikationstechnik ausgeprägter sein dürfte, als sie je war. Frankfurt ist zweifellos ein „bedeutender Finanzplatz“, und manchen gilt er auch als bedroht. Allein deshalb ist unser Thema wichtig; und auch wenn die Einschätzungen von Bedeutung und Bedrohtheit keineswegs neu sind, ist es doch aktuell. Der Aspekt der Bedrohtheit prägt, wie wir die Frage im Titel verstehen und diskutieren möchten. Was ist ein „bedeutender Finanzplatz“? Selbst wenn man das Attribut „bedeutend“ erst einmal beiseite lässt, ist die Frage keineswegs trivial. Sie zielt ja nicht nur auf eine Begriffsklärung, eine Sprachregelung ab. Hinter dem Begriff steht oft auch eine Vorstellung vom „Wesen“ dessen, was ein Begriff bezeichnet. Also: Was macht einen Finanzplatz aus? Und weiter: Warum gibt es überhaupt Finanzplätze als beträchtliche Konzentrationen von bestimmten wichtigen Aktivitäten und Institutionen? Welche Kräfte führen - oder zumindest führten - zu der räumlichen Konzentration der Aktivitäten und Institutionen, wie wirken diese Kräfte, und wie ändern sie sich gegebenenfalls? Diesen Fragen ist dieser Beitrag im Wesentlichen gewidmet, und sie prägen seinen Aufbau. Im Abschnitt II wird diskutiert, was ein „bedeutender Finanzplatz“ ist oder woran man ihn erkennt und „was er braucht“. Im Abschnitt III gehen wir zuerst auf die Frage nach der in letzter Zeit unter dem Stichwort „the end of geography“ heftig diskutierten Vorstellung einer Auflösung oder Virtualisierung der Finanzplätze ein – nicht weil dies die wichtigere Bedrohung wäre, sondern weil es die grundlegendere Frage darstellt. Dann diskutieren wir den Wettbewerb von Finanzplätzen in Europa. Den Abschluss bilden Überlegungen zu den Perspektiven des Finanzplatzes Frankfurt und der möglichen Förderung seiner Entwicklung.

Aus dem weiten Spektrum ökonomisch relevanter Fragen, die die europäische Integration und das Gesellschaftsrecht verbinden, soll hier diejenige herausgegriffen werden, ob sich die nationalen Corporate-Governance-Systeme in den großen europäischen Volkswirtschaften Deutschlands, Frankreichs und Großbritanniens unter dem Einfluß der europäischen Integration bereits aneinander angeglichen haben und ob es demnächst zu einer solchen Angleichung kommen wird. Unser Thema deckt nur einen Teil des Gesellschaftsrechts ab und geht zugleich hinsichtlich der angesprochenen rechtlichen Materie über das Gesellschaftsrecht hinaus, denn die Corporate Governance fügt sich nicht einfach in herkömmliche juristische Klassifikationen ein. Unser Vorhaben unterscheidet sich aber vor allem dadurch von einer juristischen Behandlung des Themas, daß primär ökonomische Mechanismen und Zusammenhänge angesprochen werden. Ökonomen betrachten die Corporate Governance im weiteren Kontext des Finanzsystems, denn das Corporate-Governance-System ist ein Teil des Finanzsystems eines Landes. Die Fragen, wie unterschiedlich die nationalen Systeme der Corporate Governance waren, ehe zu Beginn der 80er Jahre der Prozeß der Angleichung in Europa einsetzte, wie unterschiedlich sie heute noch sind, wie sehr sie sich somit bereits angeglichen haben und wie ein möglicher Angleichungsprozeß weitergehen könnte, sind deshalb ein Teil der weiteren Frage nach der Angleichung der Finanzsysteme in Europa. In diesem Beitrag konzentrieren wir uns aber nur auf Entwicklungen der 90er Jahre.

Although the world of banking and finance is becoming more integrated every day, in most aspects the world of financial regulation continues to be narrowly defined by national boundaries. The main players here are still national governments and governmental agencies. And until recently, they tended to follow a policy of shielding their activities from scrutiny by their peers and members of the academic community rather than inviting critical assessments and an exchange of ideas. The turbulence in international financial markets in the 1980s, and its impact on U.S. banks, gave rise to the notion that academics working in the field of banking and financial regulation might be in a position to make a contribution to the improvement of regulation in the United States, and thus ultimately to the stability of the entire financial sector. This provided the impetus for the creation of the “U.S. Shadow Financial Regulatory Committee”. In the meantime, similar shadow committees have been founded in Europe and Japan. The specific problems associated with financial regulation in Europe, as well as the specific features which distinguish the European Shadow Financial Regulatory Committee from its counterparts in the U.S. and Japan, derive from the fact that while Europe has already made substantial progress towards economic and political integration, it is still primarily a collection of distinct nation-states with differing institutional set-ups and political and economic traditions. Therefore, any attempt to work towards a European approach to financial regulation must include an effort to promote the development of a European culture of co-operation in this area, and this is precisely what the European Shadow Financial Regulatory Committee (ESFRC) seeks to do. In this paper, Harald Benink, chairman of the ESFRC, and Reinhard H. Schmidt, one of the two German members, discuss the origin, the objectives and the functioning of the committee and the thrust of its recommendations.

This paper discusses the so-called commercial approach to microfinance under economic and ethical aspects. It first shows how microfinance has developed from a purely welfare-oriented activity to a commercially relevant line of banking business. The background of this stunning success is the – almost universal – adoption of the so-called commercial approach to microfinance in the course of the last decade. As the author argues, this commercial approach is the only sound approach to adopt if one wanted microfinance to have any social and developmental impact, and therefore the wide-spread “moralistic” criticism of the commercial approach, which has again and again been expressed in the 1990s, is ill-placed from an economic and an ethical perspective. However, some recent events in microfinance raise doubts as to whether the commercial approach has not, in a number of cases, gone too far. The evident example for such a development is the Mexican microfinance institution Compartamos, which recently undertook a financially extremely successful IPO. As it seems, some microfinance institutions have by now become so radically commercial that all of those social and development considerations, which have traditionally motivated work in the field of microfinance, seem to have lost their importance. Thus there is a conflict between commercial and developmental aspirations. However, this conflict is not inevitable. The paper concludes by showing that, and how, a microfinance institution can try to combine using the strengths of the capital market and at the same time maintaining its developmental focus and importance.

A financial system can only perform its function of channelling funds from savers to investors if it offers sufficient assurance to the providers of the funds that they will reap the rewards which have been promised to them. To the extent that this assurance is not provided by contracts alone, potential financiers will want to monitor and influence managerial decisions. This is why corporate governance is an essential part of any financial system. It is almost obvious that providers of equity have a genuine interest in the functioning of corporate governance. However, corporate governance encompasses more than investor protection. Similar considerations also apply to other stakeholders who invest their resources in a firm and whose expectations of later receiving an appropriate return on their investment also depend on decisions at the level of the individual firm which would be extremely difficult to anticipate and prescribe in a set of complete contingent contracts. Lenders, especially long-term lenders, are one such group of stakeholders who may also want to play a role in corporate governance; employees, especially those with high skill levels and firm-specific knowledge, are another. The German corporate governance system is different from that of the Anglo-Saxon countries because it foresees the possibility, and even the necessity, to integrate lenders and employees in the governance of large corporations. The German corporate governance system is generally regarded as the standard example of an insider-controlled and stakeholder-oriented system. Moreover, only a few years ago it was a consistent system in the sense of being composed of complementary elements which fit together well. The first objective of this paper is to show why and in which respect these characterisations were once appropriate. However, the past decade has seen a wave of developments in the German corporate governance system, which make it worthwhile and indeed necessary to investigate whether German corporate governance has recently changed in a fundamental way. More specifically one can ask which elements and features of German corporate governance have in fact changed, why they have changed and whether those changes which did occur constitute a structural change which would have converted the old insider-controlled system into an outsider-controlled and shareholder-oriented system and/or would have deprived it of its former consistency. It is the second purpose of this paper to answer these questions.

At least in the past, banking in continental Europe has been characterised by a number of features that are quite specific to the region. They include the following: (1) banks play a strong role in their respective financial systems; (2) universal banking is prevalent; (3) not strictly profit-oriented banks play a significant role; and (4) there are considerable differences between national banking systems. It can be safely assumed that the future of banking in Europe will be shaped by three major external developments: deregulation and liberalisation; advances in information technology; and economic, financial and monetary integration. The overall consequences of these developments would be much too vast a topic to be addressed in one short paper. Therefore the present paper concentrates on the following question: Are the traditional peculiarities of the banking and financial systems of continental Europe likely to disappear as a consequence of the aforementioned external developments or are they more likely to remain in spite of these developments? The external developments affect the features specific to banking in continental Europe only indirectly and only via the strategies selected and pursued by the various players in the financial systems, notably the banks themselves, and in ways which strongly depend on the structure of the banking industry and the level of competition between banks and other providers of financial services. The paper develops an informal model of the relationships between (1) external developments, (2) bank strategies and the structure of the banking industry, and (3) the peculiarities of banking in Europe, and derives a hypothesis predicting which of the traditional peculiarities are likely to disappear and which are likely to remain. It argues that, overall, the peculiarities are not likely to disappear in the short or the medium term. First version June 2000. This version March 2001.

Paper Presented at the Conference on Workable Corporate Governance: Cross-Border Perspectives held in Paris, March 17-19, 1997 To appear in: A. Pezard/J.-M. Thiveaud: Workable Corporate Governance: Cross-Border Perspectives, Montchrestien, Paris 1997. The paper discusses the role of various constituencies in the corporate governance of a corporation from the perspective of incomplete contracts. A strict shareholder value orientation in the sense of a rule that at any time firm decisions should be made strictly in the interest of the present shareholders would make it difficult for the firm to establish long-term relationships as the potential partners would have to fear that, at a later stage of the co-operation, the shareholders or a management acting only on their behalf could exploit them because of the inevitable incompleteness of long-term contracts. One way of mitigating these problems is to put in place a corporate governance system which gives some active role to the other stakeholders or constituencies, or which makes their interests a well-defined element of the objective function of the firm. A commitment not to follow a policy of strict shareholder value maximization ex post can be efficient ex ante. Such a system would clearly differ from what is advocated by proponents of a "stakeholder approach", as it would limit the rights of the other constituencies to those which would have been agreed upon in a constitutional contract concluded between them and the founder of the firm at the time when long-term contracts are first established.

Major differences between national financial systems might make a common monetary policy difficult. As within Europe, Germany and the United Kingdom differ most with respect to their financial systems, the present paper addresses its topic under the assumption that the United Kingdom is already a part of EMU. Employing a comprehensive concept of a financial system, the author shows that there are indeed profound differences between the national financial systems of Germany and the United Kingdom. But he argues that these differences are not likely to create great problems for a common monetary policy. In the context of the present paper, one important difference between the two financial systems refers to the structure of the respective financial sector and, as a consequence, to the strength with which a given monetary policy impulse set by the central bank is passed on to the financial sector. The other important difference refers to the typical relationship between the banks and the business sector in each country which determines to what extent the financial sectors and especially the banks pass on pressure exerted on them by a monetary policy authority to their clients in their national business sector. In Germany, the central bank has a stronger influence on the financial sector than in England, while, for systemic reasons, German banks tend to soften monetary policy pressures on their customers more than British banks do. As far as the transmission of a restrictive monetary policy of the ECB to the real economy is concerned, these two differences tend to offset each other. This is good news for the advocates of a monetary union as it eases the task of the ECB when it comes to determining the strength of its monetary policy measures.

Stakeholderorientierung, Systemhaftigkeit und Stabilität der Corporate Governance in Deutschland
(2006)
Since the time of Germany’s belated industrialisation, corporate governance in Germany has been stakeholder oriented in the dual sense of attaching importance to the interests of stakeholders who are not at the same time shareholders, and of providing certain opportunities for these stakeholders to influence corporate decisions. Corporate governance is also systemic. It is a system of elements that are complementary to each other, and also consistent. In other word, it is composed of elements for which it is important that they fit together well, and in the German case these elements did fit together well until quite recently. Corporate governance as a system is itself an element of the German bank-based financial system at large and possibly even of the entire German business and economic system. Stakeholder orientation of governance is consistent with the general structure this system, and even represents one of its central elements. In retrospect, German corporate governance has also proved to be surprisingly stable. Its fundamental traits date back to the turn from the 19th to the 20th century. There are strong reasons to assume that the systemic features, that is, its complementarity and consistency, have greatly contributed to its past stability. Since about ten years now, there are growing tendencies to question the viability and stability of the German corporate governance system and even the financial system as a whole. One of the central topics in the new debate concerns the stakeholder orientation of the system, which some observers and critics consider as the main weakness of the “German model” under the increasing pressures of globalisation and European integration. As far as their development over time is concerned, systems of complementarity elements exhibit certain peculiarities: (1) They do not adjust easily to changing circumstances. (2) Changes concerning important individual elements, such as the stakeholder orientation of governance, tend to jeopardize the viability and the stability of the entire system. (3) While they appear to be stable, systems shaped by complementary may simply be rigid and tend to break under strong external pressure. “Breaking” means that a system undergoes a fundamental transformation. It seems plausible to assume that the German financial system is already in the middle of such a transformation. It is yet another consequence of its systemic character that this transformation is not likely to be a smooth and gradual process and that it will not lead to a “mixed model” but rather to the adoption of a capital market-based financial system as it prevails in the Anglo-Saxon countries. In such a system, corporate governance cannot be geared to catering to the interests of stakeholders, and an active role for them would not even make any economic sense.

Untersuchungsgegenstand ist der empirische Gehalt der ökonomischen Theorie eines Hedgings auf Unternehmensebene. In den USA wurde die Hedging-Theorie in einer Reihe von empirischen Studien aufgegriffen. Die Befunde sind zumeist konsistent mit dem Erklärungsansatz von Froot/Scharfstein/Stein (1993), wonach eine Verringerung der Cashflow-Volatilität – unter der Annahme steigender Außenfinanzierungskosten – zu einer Reduzierung von Unterinvestitionskosten führt. Bei deutschen Unternehmen besitzt dieser Ansatz bemerkenswerterweise jedoch nur einen geringen Erklärungsgehalt. Die Ergebnisunterschiede können auf unterschiedliche Kapitalmarktverhältnisse zurückgeführt werden: Die unterstellten steigenden Kosten der Außenfinanzierung besitzen für deutsche Unternehmen aufgrund der Dominanz des Bezugsrechtsverfahrens sowie der Rolle der Hausbank als Mechanismus zur Überwindung von Informationsproblemen eine vergleichsweise geringere Bedeutung. Die Managerinteressen erweisen sich bei deutschen Unternehmen als eine wesentliche Hedging-Determinante. Zwischen der Höhe des gebundenen Managervermögens und der Hedging-Wahrscheinlichkeit besteht entsprechend der Hedging-Theorie ein signifikanter positiver Zusammenhang. Entgegen den amerikanischen Befunden kann jedoch eine disziplinierende Wirkung von Großaktionären auf die Hedging-Entscheidung nicht beobachtet werden. Zur Berücksichtigung der spezifischen deutschen Kapitalmarktverhältnisse wird der Einfluss von Bankenbeteiligungen und Familienunternehmen auf die Hedging-Entscheidung untersucht. Ein Bankeneinfluss auf die Derivateeinsatz-Entscheidung kann jedoch nicht festgestellt werden. Entgegen Diversifikations- und Kapitalmarktüberlegungen besteht bei Familienunternehmen interessanterweise eine signifikant geringere Hedging-Wahrscheinlichkeit.

Sowohl die Diversifikation als auch die Fokussierung von Unternehmensaktivitäten werden häufig mit der Maximierung des Unternehmenswertes begründet. Wir untersuchen die Auswirkungen auf den Aktienkurs für 184 Akquisitionen sowie 139 Desinvestitionen deutscher Konzerne im Zeitraum von 1996-2005. Unternehmensdiversifikationen üben, entgegen der oft geäußerten Kritik, keinen signifikant negativen Einfluss auf den Marktwert aus. Fokussierende Unternehmensakquisitionen hingegen sind mit einem signifikanten Wertaufschlag verbunden. Der Verkauf von Unternehmensteilen führt generell zu einer Marktwertsteigerung. Dabei führen Abspaltungen außerhalb des Kerngeschäfts zu einer – allerdings insignifikant – höheren Wertsteigerung als Desinvestitionen von Kerngeschäftsaktivitäten. Statt eines systematischen Diversifikationsabschlags finden wir somit einen „Fokussierungsaufschlag“ für den deutschen Markt.

Kapitalmarktorientierte Risikosteuerung in Banken : Marktwertsteuerung statt Marktzinsmethode
(2005)
In diesem Beitrag wird das Konzept der Marktzinsmethode als Grundlage der dualen Risikosteuerung von Kredit- und Marktpreisrisiken in Frage gestellt. Die Kreditrisiken einer Bank implizieren bonitätsinduzierte Marktpreisrisiken und bankspezifische Refinanzierungskosten. Während die bonitätsinduzierten Marktpreisrisiken in der dualen Risikosteuerung keine Berücksichtigung finden, werden die bankspezifischen Refinanzierungskosten zwar erkannt, aber bankintern nicht verursachungsgerecht zugeordnet. Das Grundmodell der Marktzinsmethode bietet keine Lösungsansätze zur Behebung dieser Probleme. Demgegenüber lassen sich die Fehlsteuerungsimpulse von vornherein durch eine konsequente Marktbewertung (Mark to Market) aller Finanzinstrumente vermeiden. Als Ausblick werden erste Überlegungen zur Implementierung einer umfassenden Marktwertsteuerung in Banken entwickelt und exemplarisch ein hierfür geeignetes Bewertungsmodell vorgestellt.

This study contributes to the valuation of employee stock options (ESO) in two ways: First, a new pricing model is presented, admitting a major part of calculations to be solved in closed form. Designed with a focus on good replication of empirics, the model fits with publicly observable exercise characteristics better than earlier models. In particular, it is able to account for the correlation of the time of exercise and the stock price at exercise, suspected of being crucial for the option value. The impact of correlation is weak, however, whereas cancellations play a central role. The second contribution of this paper is an examination to what extent the ESO pricing method of SFAS 123 is subject to discretion of the accountant. Given my model were true, the SFAS price would be a good proxy. Yet, outside shareholders usually cannot observe one of the SFAS input parameters. On behalf of an example I show that there is wide latitude left to the accountant.

This paper determines the cost of employee stock options (ESOs) to shareholders. I present a pricing method that seeks to replicate the empirics of exercise and cancellation as good as possible. In a first step, an intensity-based pricing model of El Karoui and Martellini is adapted to the needs of ESOs. In a second step, I calibrate the model with a regression analysis of exercise rates from the empirical work of Heath, Huddart and Lang. The pricing model thus takes account for all effects captured in the regression. Separate regressions enable me to compare options for top executives with those for subordinates. I find no price differences. The model is also applied to test the precision of the fair value accounting method for ESOs, SFAS 123. Using my model as a reference, the SFAS method results in surprisingly accurate prices.

Seit der Einführung des Deutschen Corporate Governance Kodex (Kodex) im Jahr 2002 sind deutsche börsennotierte Unternehmen zur Abgabe der Entsprechenserklärung gemäß § 161 AktG verpflichtet (Comply-or-Explain-Prinzip). Auf der Basis dieser Information soll durch den Druck des Kapitalmarkts die Einhaltung des Kodex überwacht und gegebenenfalls sanktioniert werden. Dabei wird regelmäßig postuliert, dass bei überdurchschnittlicher Befolgung bzw. Nichtbefolgung der Kodex-Empfehlungen eine Belohnung durch Kurszuschläge bzw. eine Sanktionierung durch Kursabschläge erfolgt. Die Ergebnisse einer Ereignisstudie zeigen, dass die Abgabe der Entsprechenserklärung keine erhebliche Kursbeeinflussung auslöst und die für das Enforcement des Kodex angenommene (und erforderliche) Selbstregulierung durch den Kapitalmarkt nicht stattfindet. Es wird daher kritisch hinterfragt, ob der für den Kodex gewählte und grundsätzlich zu begrüßende flexible Regulierungsansatz im System des zwingenden deutschen Gesellschaftsrechts einen geeigneten Enforcement-Mechanismus darstellt. This paper studies the short-run announcement effects of compliance with the German Corporate Governance Code (‘the Code’) on firm value. Event study results suggest that firm value is unaffected by the announcement, although such market reactions to the first time disclosure of the declaration of conformity were widely assumed by the private and public promoters of the Code. This result from acceptance of the German Code add evidence to the hypothesis that regulatory corporate governance initiatives that rely on mandatory disclosure without monitoring and enforcement are ineffective in civil law countries.

Ja, der Ablauf der Lock-up-Frist ist ein kursrelevantes Ereignis. Wir untersuchen Kursreaktionen auf das Ende der Lock-up-Frist bei 142 Unternehmen des Neuen Marktes. Da der Ablauf der Sperrfrist bereits zum Zeitpunkt des Börsengangs bekannt ist, erwarten wir bei einem (semi-)informationseffizienten Kapitalmarkt durchschnittlich keine Kursreaktion. Im Rahmen einer Ereignisstudie zeigen wir aber, dass sich am Ende der Sperrfrist signifikant negative Überrenditen ergeben. Durch eine differenzierte Analyse stellen wir fest, dass firmenspezifische Faktoren (Volatilität, Performance, Free Float) die Kursreaktionen am Ende der Lock-up-Periode beeinflussen. Die Befunde unserer Untersuchung belegen die Notwendigkeit klarer Regeln für mehr Transparenz nach dem Börsengang. Bedeutsam sind die vorliegenden Ergebnisse vor allem vor dem Hintergrund der aktuellen Diskussion um eine Erweiterung der insiderrechtlichen Meldepflichen im Rahmen des 4. Finanzmarktförderungsgesetzes. This paper explores the materiality of expirations of lock-up provisions that prevent insiders from selling their shares after the initial public offering (IPO). We examine 172 lock-up agreements of 142 IPOs floated on Germany’s New Market. Since the date of the lock-up expiration is common knowledge at the IPO, we would not expect to find abnormal returns surrounding the event day, assuming that markets are informationally efficient. However, using an event-study methodology we detect statistically significant negative abnormal returns and a twenty-five percent increase in trading volume surrounding lock-up expiration. The negative abnormal returns are larger for firms with high volatility, superior performance after the IPO, and low free float. The results of our study raise important regulatory issues with respect to disclosure rules of firms going public. We argue that insiders should be legally required to disclose their sell transactions in order to protect new and less informed shareholders.

This paper investigates the impact of IT standardization on bank performance based on a panel of 457 German savings banks over the period from 1996 to 2006. We measure IT standardization as the fraction of IT expenses for centralized services over banks' total IT expenses. Bank efficiency, in turn, is measured by traditional accounting performance indicators as well as by cost and profit efficiencies that are estimated by a stochastic frontier approach. Our results suggest that IT standardization is conducive to cost efficiency. The relation is positive and robust for small and medium-sized banks but vanishes for very large banks. Furthermore, our study confirms the often cited computer paradox by showing that total IT expenditures negatively impact cost efficiency and have no influence on bank profits. To the best of our knowledge, this paper is first to empirically explore whether IT standardization enhances efficiency by employing genuine data of banks' IT expenditures.

The use of catastrophe bonds (cat bonds) implies the problem of the so called basis risk, resulting from the fact that, in contrast to traditional reinsurance, this kind of coverage cannot be a perfect hedge for the primary’s insured portfolio. On the other hand cat bonds offer some very attractive economic features: Besides their usefulness as a solution to the problems of moral hazard and default risk, an important advantage of cat bonds can be seen in the presumably lower transaction costs compared to (re)insurance products. Insurance coverage usually incurs costs of acquisition, monitoring and loss adjustment, all of which can be reduced by making use of the financial markets. Additionally, cat bonds are only weakly correlated with market risk, implying that in perfect financial markets these securities could be traded at a price including just small risk premiums. Although these aspects have been identified in economic literature, to our knowledge there has been no publication so far that formally addresses the trade-off between basis risk and transaction cost. In this paper, therefore, we introduce a simple model that enables us to analyze cat bonds and reinsurance as substitutional risk management tools in a standard insurance demand theory environment. We concentrate on the problem of basis risk versus transaction cost, and show that the availability of cat bonds affects the structure of optimal reinsurance contract design in an interesting way, as it leads to an increase of indemnity for small losses and a decrease of indemnity for large losses.

It is the objective of this paper to determine the voting premium for French shares by comparing the values of voting and non-voting shares, and to analyze the value of the voting rights. The study uses data for 25 French companies which had both types of shares outstanding and traded on the stock exchange during the entire period from 1986 to 1996, or for some time during this interval. The average value of the voting premium is 51,35%.
The paper analyzes the reasons for this surprisingly high value by testing different hypotheses based on dividend differences, the revival) of the voting right, capitalization, shareholder structure, and the share of non-voting capital in total equity capital. The regressions show that the shareholder structure strongly influences the value of the voting premium.
A case study of the attempted takeover of Casino by Promodes shows that investors attach a much higher value to the voting right during relevant situations than at other tomes. Both companies involved had, at the time, two types of shares outstanding and listed. Furthermore the paper shows that non-voting shares have never played an important role in equity finance in France since the companies have different alternatives.
In an international cumparison, France is found to have the second highest voting premium, exceeded only by that of Italy. A probable reason is the low quality of the national accounting standards and the low level of minority shareholder protection.

This paper examines intraday stock price effects and trading activity caused by ad hoc disclosures in Germany. The evidence suggests that the observed stock prices react within 90 minutes after the ad hoc disclosures. Trading volumes take even longer to adjust. We find no evidence for abnormal price reactions or abnormal trading volume before announcements. The bigger the company that announces an ad hoc disclosure, the less severe is the abnormal price effect following the announcement. The number of analysts is negatively correlated to the trading volume effect before the ad hoc disclosure. The higher the trading volume on the last trading day before the announcement, the greater is the price effect after the ad hoc disclosures and the greater the trading volume effect. Keywords: ad hoc disclosure rules, intraday stock price adjustments, market efficiency.

Substantial research attention has been devoted to the pension accumulation process, whereby employees and those advising them work to accumulate funds for retirement. Until recently, less analysis has been devoted to the pension decumulation process – the process by which retirees finance their consumption during retirement. This gap has recently begun to be filled by an active group of researchers examining key aspects of the pension payout market. One of the areas of most interesting investigation has been in the area of annuities, which are financial products intended to cover the risk of retirees outliving their assets. This paper reviews and extends recent research examining the role of annuities in helping finance retirement consumption. We also examine key market and regulatory factors.

As past research suggest, currency exposure risk is a main source of overall risk of international diversified portfolios. Thus, controlling the currency risk is an important instrument for controlling and improving investment performance of international investments. This study examines the effectiveness of controlling the currency risk for international diversified mixed asset portfolios via different hedge tools. Several hedging strategies, using currency forwards and currency options, were evaluated and compared with each other. Therefore, the stock and bond markets of the, United Kingdom, Germany, Japan, Switzerland, and the U.S, in the time period of January 1985 till December 2002, are considered. This is done form the point of view of a German investor. Due to highly skewed return distributions of options, the application of the traditional mean-variance framework for portfolio optimization is doubtful when options are considered. To account for this problem, a mean-LPM model is employed. Currency trends are also taken into account to check for the general dependence of time trends of currency movements and the relative potential gains of risk controlling strategies.

This article presents an overview of the contemporary German insurance market, its structure, players, and development trends. First, brief information about the history of the insurance industry in Germany is provided. Second, the contemporary market is analyzed in terms of its legal and economic structure, with statistics on the number of companies, insurance density and penetration, the role of insurers in the capital markets, premiums split, and main market players and their market shares. Furthermore, the three biggest insurance lines—life, health, and property and casualty—are considered in more detail, such as product range, country specifics, and insurance and investment results. A section on regulation outlines its implementation in the insurance sector, offering information on the underlying legislative basis, supervisory body, technical procedures, expected developments, and sources of more detailed information.

The purpose of this paper is to compare three different index construction methodologies of commercial property investments. We examine for different European countries (i) appraisal-based indices and methods of „unsmoothing“ the corresponding return series, (ii) indices that trace average ex-post transaction prices over time, and (iii) indices based on Real Estate Investment Trust share prices.

Real estate is an important asset, but as a direct investment subject to several difficulties. Shares of public open end funds or of real estate stock corporations represent a possible way for an investor to avoid these problems. The focus of this paper is the analysis of inflation risk of European real estate securities. An overview of the institutional frameworks regarding these companies is given. The returns of real estate securities in France, Germany, Switzerland and the United Kingdom are examined for the period 1980:1-1998:12. Besides the classical Fama/Schwert-approach, shortfall risk measurements have been used. In this context, transaction costs in particular have been taken into account.

In this paper, we analyze economies of scale for German mutual fund complexes. Using 2002-2005 data of 41 investment management companies, we specify a hedonic translog cost function. Applying a fixed effects regression on a one-way error component model there is clear evidence of significant overall economies of scale. On the level of individual mutual fund complexes we find significant economies of scale for all of the companies in our sample. With regard to cost efficiency, we find that the average mutual fund complexes in all size quartiles deviate considerably from the best practice cost frontier.

Past research suggests that international real estate markets show return characteristics and interrelationships with other asset classes, which probably qualify them as an interesting component of national and international asset allocation decisions. However, the special characteristics of real estate assets are quite distinct from that of financial assets, such as stocks and bonds. This is also the case for real estate return distributions. Therefore, the proper integration of real estate markets into asset allocation decisions requires profound understanding of real estate returns' distributional characteristics .
Because of the particular characteristics of real estate, representing real estate markets through reliable a time-series is a complex task. Consequently, reliable real estate indices with a sufficiently long history in major international real estate markets are only scarcely available. Most of the research that has been done on real estate returns was done for the U.K. and U.S., where eligible indices exist. On the other hand, in other important real estate markets, such as Germany, either little or no research has been perfoimed.
In this analysis, the methodology of Maurer, Sebastian and Stephan (2000) for indirectly deriving an appraisal-based index for the German commercial real estate market will be applied. This approach is solely based on publicly available data from German open-ended real estate investment trusts. It could also provide a solution to deriving a reliable real estate time-series for other markets.
We will extend previous analyses for the U.K. and U.S. to provide additional fundamental insights into the return characteristics of the German commercial real estate market. Despite univariate considerations, the main focus is the interrelationships between various international real estate markets, as well as between those respective markets and the international stock and bond markets.

Open-end real estate funds (so called “Offene Immobilienfonds”) play a major role in the German market for securitised real estate investments. Such funds are pools of money from many investors, which are invested in real estate by special investment management companies. This study seeks to identify the risk and return profile of this investment vehicle (before and after income taxes), to compare them with those of other major asset classes, and to provide implications for their appropriate role in a mixed-asset portfolio. Addition-ally, an overview of the institutional architecture and role of German open-end real estate funds is given. Empirical evidence suggests that the financial characteristics of open-end real estate funds are in many respects similar to those reported for direct real estate invest-ments. Accordingly, German open-end real estate funds qualify for medium and long-term investment horizons, rather than for shorter holding periods.

The present paper seeks to study the possible diversification potential by the integration of indirect real estate investments in international portfolios. To this end, monthly index-return time-series in the time-period from January 1985 till December 1998 from real estate investment companies as well as common stocks and bonds in Germany, France, Switzerland, Great Britain and the USA were used. We utilize, due to the critical normal distribution assumption, a mean/lower-partial-moment framework. In order to take into account the influence of the currency risk for international investments the analyses have been undertaken both with as well as without hedging the currency risk. We take the viewpoint of a German as well as that of a US-investor to gain insight into the dependency of the diversification potential on the reference currency of the investor.

Der vorliegende Beitrag zeigt auf, wie hedonische Preisindizes für Immobilien auf der Basis von Transaktionen berechnet werden können. Der Heterogenität der Immobilien wird dabei durch ein ökonometrisches Modell Rechnung getragen, wobei in dieser Arbeit das Problem der Wahl einer geeigneten Funktionsform durch eine Transformation nach dem Ansatz von Box/Cox (1964) explizit berücksichtigt wird. Die Datenbasis deckt etwa 65% der Transaktionen des Wohnungsmarktes im Zeitraum 1990-1999 ab. Die Korrektur aufgrund unvollständiger Angaben führt zu einem Datensatz von 84 686 Transaktionen. Dieser Datensatz ist ein Vielfaches dessen, was bisher vergleichbaren Studien zugrunde lag und stellt damit eine international einmalige Datengrundlage dar.

Public employee pension systems throughout the developed world have traditionally been of the pay-as-you-go (PAYGO) defined benefit (DB) variety, where pensioner payments are financed by taxes (contributions) levied on the working generation. But as the number of retirees rises relative to the working-age group, such systems have begun to face financial distress. This trend has been exacerbated in many countries, among them Germany, by high unemployment rates producing further deterioration of the contribution base. In the long run, public sector pension benefits will have to be cut or contributions increased, if the systems are to be maintained. An alternative path sometimes offered to ease the crunch of paying for public employee pensions is to move toward funding: here, plan assets are gradually built up, invested, and enhanced returns devoted to partly defray civil servants’ pension costs. In this study, we evaluate the impact of introducing partial prefunding, paired with a strategic investment policy for the German federal state of Hesse. The analysis assesses the impact of introducing a supplementary tax-sponsored pension fund whose contributions are invested in the capital market and used to relieve the state budget from (some) pension payments. Our model determines the expectation and the Conditional Value-at-Risk of economic pension costs using a stochastic simulation process for pension plan assets. This approach simultaneously determines the optimal contribution rate and asset allocation that controls the expected economic costs of providing the promised pensions, while at the same time controlling investment risk. Specifically, we offer answers to the following questions: 1. How can the plan be designed to control cash-flow shortfall risk, so as to mitigate the potential burden borne by future generations of taxpayers? 2. What is the optimal asset allocation for this fund as it is built up, to generate a maximum return while simultaneously restricting capital market and liability risk? 3. What are reasonable combinations of annual contribution rates and asset allocation to a state-managed pension fund, which will limit costs of providing promised public sector pensions? We anticipate that this research will interest several sorts of policymaker groups. First, focusing on the German case, the state and Federal governments should find it relevant, as these entities face considerable public sector pension liabilities. Second, our findings will also be of interest to other European countries, as most have substantial underfunded defined benefit plans for civil servants. In what follows, we first offer a brief description of the structure of civil servant pensions in Germany, focusing on their benefit formulas, their financing, and the resulting current as well as future plan obligations for taxpayers. Next, we turn to an analysis of the actuarial status of the Hesse civil servants’ pension plan and evaluate how much would have to be contributed to fund this plan in a nonstochastic context. Subsequently we evaluate the asset-liability and decision-making process from the viewpoint of the plan sponsor, to determine sensible plan asset allocation behavior. A final section summarizes findings and implications.

In this paper we study the benefits derived from international diversification of stock portfolios from German and Hungarian point of view. In contrast to the German capital market, which is one of the largest in the world, the Hungarian Stock Exchange is an emerging market. The Hungarian stock market is highly volatile, high returns are often accompanied by extremely large risk. Therefore, there is a good potential for Hungarian investors to realize substantial benefits in terms of risk reduction by creating multi-currency portfolios. The paper gives evidence on the above me ntioned benefits for both countries by examining the performance of several ex ante portfolio strategies. In order to control the currency risk, different types of hedging approaches are implemented.

This paper analyzes the relation between demographic structure and real asset returns on treasury bills, bonds and stocks for the G7-countries (United States, Canada, Japan, Italy, France, the United Kingdom and Germany). A macroeconomic multifactor model is used to examine a variety of different demographic factors from 1951 to 2002. There was no robust relationship found between shocks in demographic variables and asset returns in the framework of these models, which suggests that Asset Meltdown is rather fiction than fact.

Many tax-codes around the world allow for special taxable treatment of savings in retirement accounts. In particular, profits in retirement accounts are usually tax exempt which allow investors to increase an asset’s return by holding it in such a retirement account. While the existing literature on asset location shows that risk-free bonds are usually the preferred asset to hold in a retirement account, we explain how the tax exemption of profits in retirement accounts affects private investors’ asset allocation. We show that total final wealth can be decomposed into what the investor would have earned in a taxable account and what is due to the tax exemption of profits in the retirement account. The tax exemption of profits can thus be considered a tax-gift which is similar to an implicit bond holding. As this tax-gift’s impact on total final wealth decreases over time, so does the investor’s equity exposure.

The tax codes in many countries allow for special tax advantages for investments in special retirement plans. Probably the most important advantage to these plans is that profits usually remain untaxed. This paper deals with the question, which assets are preferable in a taxdeferred account (TDA). Contrary to the conventional wisdom that one should prefer bonds in the TDA, it is shown that especially in early years, stocks can be the preferred asset to hold in the TDA for an investor maximizing final wealth, given a certain asset allocation. The higher the performance of stocks compared to bonds, the higher the tax burden put on stocks compared to bonds. Simultaneously, the longer the remaining investment horizon, the larger the relative outperformance of the optimal asset location strategy compared to the myopic strategy of locating bonds in the TDA. An algorithm is provided to determine the investment strategy that maximizes (expected) funds at the end of a given investment horizon when there is an analytical solution.

Who knows what when? : The information content of pre-IPO market prices : [Version March/June 2002]
(2002)
To resolve the IPO underpricing puzzle it is essential to analyze who knows what when during the issuing process. In Germany, broker-dealers make a market in IPOs during the subscription period. We examine these pre-issue prices and find that they are highly informative. They are closer to the first price subsequently established on the exchange than both the midpoint of the bookbuilding range and the offer price. The pre-issue prices explain a large part of the underpricing left unexplained by other variables. The results imply that information asymmetries are much lower than the observed variance of underpricing suggests.

Rating agencies state that they take a rating action only when it is unlikely to be reversed shortly afterwards. Based on a formal representation of the rating process, I show that such a policy provides a good explanation for the empirical evidence: Rating changes occur relatively seldom, exhibit serial dependence, and lag changes in the issuers’ default risk. In terms of informational losses, avoiding rating reversals can be more harmful than monitoring credit quality only twice per year.

Die Altersvorsorge in Russland - Theoretische Analyse, aktuelle Rahmenbedingungen und ihre Umsetzung
(2005)
Das russische Rentenversicherungssystem befindet sich in der Krise. Wie in einer Vielzahl entwickelter Staaten auch, erodiert die Basis des umlagefinanzierten Rentensystems („Generationenvertrag“) auf Grund des demografischen Wandels. Dies wird verstärkt durch die mangelnde Wirtschaftskraft Russlands. Ausgangspunkt der Diskussion des russischen Rentenmodells in diesem Artikel ist die Darstellung der theoretischen Grundannahmen, die Analyse der aktuellen und zukünftigen Rahmenbedingungen sowie eine Prognose der natürlichen und räumlichen Bevölkerungsbewegung in Russland. Hierauf folgt die Präsentation der gegenwärtigen Situation einschließlich der bereits erfolgten ersten Schritte zu einer umfassenden Neuordnung des Rentenversicherungssystems sowie die Darstellung von „hot steps“ auf dem Weg zu einer nachhaltigen Alterssicherung.

Economic theory suggests that a commitment by a firm to increased levels of disclosure should lower the information asymmetry component of the firm’s cost of capital. But whi le the theory is compelling, so far empirical results relating increased levels of disclosure to measurable economic benefits have been mixed. One explanation for the mixed results among studies using data from firms publicly registered in the US is that, under current US reporting standards, the disclosure environment is already rich. In this paper, we study German firms that have switched from the German to an international reporting regime (IAS or US -GAAP), thereby committing themselves to increased le vels of disclosure. We show that proxies for the information asymmetry component of the cost of capital for the switching firms, namely the bid-ask spread and trading volume, behave in the predicted direction compared to firms employing the German reporti ng regime.

This paper studies the incentives of German firms to voluntarily disclose cash flow statements over time. While cash flow statement are mandated under many GAAP regimes, its disclosure has not been mandatory in Germany until recently. Nevertheless, an increasing number of firms provides cash flow statements voluntarily. These firms are likely to be influenced by recommendations of the German accounting profession, IAS 7 as well as the respective standards of other countries. The idea of the paper is to study this influence by looking at the adoption pattern over time and the format of the cash flow statement. It documents the development of voluntary cash flow statement disclosures by German firms with respect to ”milestones” in the evolution of German professional recommendations and respective international standards. The cross-sectional determinants of voluntary and international cash flow statements are analyzed using probit regressions and factor analysis. The results are generally consistent with the idea that capital-market forces drive voluntary cash flow statements that are in line with international reporting practice.

Discretionary disclosure theory suggests that firms' incentives to provide proprietary versus nonproprietary information differ markedly. To test this conjecture, the paper investigates the incentives of German firms to voluntarily disclose business segment reports and cash flow statements in their annual financial reports. While the former is likely to reveal proprietary information to competitors, the latter is less proprietary in nature. Using these proxies for proprietary and non-proprietary disclosures, respectively, I find that the determinants or at least their relative magnitudes differ in a way consistent with the proprietary cost hypothesis. That is, cash flow statement disclosures appear to be governed primarily by capital-market considerations, whereas segment disclosures are more strongly associated with proxies for product-market and proprietary-cost considerations.

This paper investigates whether firms employing IAS or US GAAP exhibit measurable differences in proxies for information asymmetry and market liquidity. Sample firms are drawn from the "New Market" at the Frankfurt Stock Exchange. All firms listed in this market segment are required to provide financial statements in accordance with either IAS or US GAAP as part of the listing agreement. The sample choice provides a market-based comparison of the two standards holding disclosure requirements and standard enforcement constant. I find that differences in the bid-ask spread and trading volume are relatively small and more likely to be driven by firm characteristics than the choice of accounting standards. In contrast, New Market firms have lower spreads and higher turnover when compared with size-matched firms in other market segments following German GAAP. The results suggests that rigid disclosure regulation of the New Market matters in terms of information asymmetry and liquidity, but that the choice between IAS and US GAAP is of second order importance.

Open source projects produce goods or standards that do not allow for the appropriation of private returns by those who contribute to their production. In this paper we analyze why programmers will nevertheless invest their time and effort to code open source software. We argue that the particular way in which open source projects are managed and especially how contributions are attributed to individual agents, allows the best programmers to create a signal that more mediocre programmers cannot achieve. Through setting themselves apart they can turn this signal into monetary rewards that correspond to their superior capabilities. With this incentive they will forgo the immediate rewards they could earn in software companies producing proprietary software by restricting the access to the source code of their product. Whenever institutional arrangements are in place that enable the acquisition of such a signal and the subsequent substitution into monetary rewards, the contribution to open source projects and the resulting public good is a feasible outcome that can be explained by standard economic theory.

This paper studies a setting in which a risk averse agent must be motivated to work on two tasks: he (1) evaluates a new project and, if adopted, (2) manages it. While a performance measure which is informative of an agent´s action is typically valuable because it can be used to improve the risk sharing of the contract, this is not necessarily the case in this two-task setting. I provide a sufficient condition under which a performance measure that is informative of the second task is worthless for contracting despite the agent being risk averse. This shows that information content is a necessary but not a sufficient condition for a performance measure to be valuable.

It is widely believed that the ideal board in corporations is composed almost entirely of independent (outside) directors. In contrast, this paper shows that some lack of board independence can be in the interest of shareholders. This follows because a lack of board independence serves as a substitute for commitment. Boards that are dependent on the incumbent CEO adopt a less aggressive CEO replacement rule than independent boards. While this behavior is inefficient ex post, it has positive ex ante incentive effects. The model suggests that independent boards (dependent boards) are most valuable to shareholders if the problem of providing appropriate incentives to the CEO is weak (severe).

Im Rahmen wertorientierter Unternehmensführung gewinnen Erfolgsbeteiligungen immer größere Verbreitung. Besonders populär ist das EVA-Bonussystem, das auf dem Erfolgskonzept "Economic Value Added" von STERN STEWART & Co. beruht. In der vorliegenden Arbeit wird gezeigt, daß dieses Bonussystem gegen die Bedingung der Anreizkompatibilität verstößt: Der Entscheidungsträger kann finanzielle Vorteile erzielen, indem er Investitionsentscheidungen trifft, die aus Sicht der Anteilseigner nachteilig sind. Insbesondere besteht die Tendenz zur Unterinvestition. Die Darstellungen beruhen auf der Annahme, daß nicht nur die Anteilseigner zukünftige Einkünfte (bzw. Überschüsse) mit einem risikoangepaßten Zinssatz diskontieren, sondern auch der Entscheidungsträger. Zunächst werden die theoretischen Grundlagen dargestellt. Wenn bei gegebener Risikoklasse der Entscheidungsträger erwartete Prämien mit dem Kalkulationszinsfuß k +D diskontiert und die Anteilseigner erwartete Überschüsse des Leistungsbereichs mit k diskontieren, besteht bei einem im Zeitablauf konstanten Prämiensatz f und Überschußbeteiligung nur dann Anreizkompatibilität, wenn D= 0 gilt. Für D> 0 besteht die Tendenz zur Unterinvestition. Sie ist um so größer, je höher D ist und je später die potentiellen Projektüberschüsse anfallen. Bei Beteiligung am Residualgewinn ergeben sich dieselben Anreizwirkungen wie bei Überschußbeteiligung, sofern die kalkulatorischen Zinsen mit dem risikolosen Zinssatz r ermittelt werden. Werden sie mit k ermittelt, so wird (für k>r ) im Vergleich zu einer Überschußbeteiligung die Tendenz zur Unterinvestition ausgelöst (sofern D= 0) oder verstärkt (sofern D> 0). Die Tendenz zur Unterinvestition ist jeweils um so gravierender, je später aktivierte Anschaffungsauszahlungen als Abschreibungen zu verrechnen sind und je höher der für die Ermittlung der kalkulatorischen Zinsen auf die (Rest-)Buchwerte maßgebliche Zinssatz k ist. Der Economic Value Added stellt eine Konkretisierung des Residualgewinns dar. Auch bei dem darauf aufbauenden (EVA-)Bonussystem besteht die Tendenz zu Fehlentscheidungen (insbesondere zur Unterinvestition). Sie resultiert vor allem aus der Ermittlung der kalkulatorischen Zinsen mit dem risikoangepaßten Zinssatz k, den geforderten "Bereinigungen" bei der Ermittlung des investierten Kapitals bzw. des Periodenerfolges und gegebenenfalls der Wahl der Erfolgsänderung gegenüber dem Vorjahr als Bemessungsgrundlage.

Vor dem Hintergrund allgemeiner Bedingungen der Anreizkompatibilität wird für verschiedenen Kapitalmarktmodelle untersucht, ob zwischen den Anteilseignern eines Unternehmens Einmütigkeit besteht und, wenn ja, mit welchem Unternehmensziel der finanzielle Nutzen der Anteilseigner maximiert wird. Von besonderer Bedeutung für die Anreizkompatibilität der üblichen linearen Erfolgsteilung ist die Bedingung pareto-effizienter Risikoteilung. Sind für den Erfolg des Unternehmens spezifische Störterme relevant und soll der Entscheidungsträger in relativ starkem Umfang am Erfolg beteiligt werden, ist die Risikoteilung zwischen ihm und den (anderen) Anteilseignern pareto-inferior. Anreizkompatible erfolgsorientierte Belohnungs- bzw. Prämienfunktionen für den Entscheidungsträger sind dann konvex und zustandsabhängig. Aktienoptionsprogramme können als Approximationen an solche Prämienfunktionen interpretiert werden.

Mutual insurance companies and stock insurance companies are different forms of organized risk sharing: policyholders and owners are two distinct groups in a stock insurer, while they are one and the same in a mutual. This distinction is relevant to raising capital, selling policies, and sharing risk in the presence of financial distress. Up-front capital is necessary for a stock insurer to offer insurance at a fair premium, but not for a mutual. In the presence of an owner-manager conflict, holding capital is costly. Free-rider and commitment problems limit the degree of capitalization that a stock insurer can obtain. The mutual form, by tying sales of policies to the provision of capital, can overcome these problems at the potential cost of less diversified owners.

When performance measures are used for evaluation purposes, agents have some incentives to learn how their actions affect these measures. We show that the use of imperfect performance measures can cause an agent to devote too many resources (too much effort) to acquiring information. Doing so can be costly to the principal because the agent can use information to game the performance measure to the detriment of the principal. We analyze the impact of endogenous information acquisition on the optimal incentive strength and the quality of the performance measure used.

We analyze the effect of committee formation on how corporate boards perform two main functions: setting CEO pay and overseeing the financial reporting process. The use of performance-based pay schemes induces the CEO to manipulate earnings, which leads to an increased need for board oversight. If the whole board is responsible for both functions, it is inclined to provide the CEO with a compensation scheme that is relatively insensitive to performance in order to reduce the burden of subsequent monitoring. When the functions are separated through the formation of committees, the compensation committee is willing to choose a higher pay-performance sensitivity as the increased cost of oversight is borne by the audit committee. Our model generates predictions relating the board committee structure to the pay-performance sensitivity of CEO compensation, the quality of board oversight, and the level of earnings management.

Performance measures shall enhance the performance of companies by directing the attention of decision makers towards the achievement of organizational goals. Therefore, goal congruence is regarded in literature as a major factor in the quality of such measures. As reality is affected by many variables, in practice one has tried to achieve a high degree of goal congruence by incorporating an increasing number of these variables into performance measures. However, a goal congruent measure does not lead automatically to superior decisions, because decision makers’ restricted cognitive abilities can counteract the intended effects. This paper addresses the interplay between goal congruence and complexity of performance measures considering cognitively-restricted decision makers. Two types of decision quality are derived which allow a differentiated view on the influence of this interplay on decision quality and learning. The simulation experiments based on this differentiation provide results which allow a critical reflection on costs and benefits of goal congruence and the assumptions regarding the goal congruence of incentive systems.
