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.
