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.
This paper investigates the magnitude and the main determinants of share price reactions to buy-back announcements of German corporations. Based on a sample of 224 announcements from the period May 1998 to April 2003 we find average cumulative abnormal returns around -7.5% for the thirty days preceding the announcement and around +7.0 % for the ten days following the announcement. We regress postannouncement abnormal returns with multiple firm characteristics and provide evidence which supports the undervaluation signaling hypothesis but not the excess cash hypothesis. In extending prior empirical work, we also analyze price effects from an initial statement by management that it intends to seek shareholder approval for a buy-back plan. Observed cumulative abnormal returns on this initial date are in excess of 5% implying a total average price effect between 12% and 15% from implementing a buy-back plan. We conjecture that the German regulatory environment is the main reason why market variations to buy-back announcements are much stronger in Germany than in other countries and conclude that initial statements by managers to seek shareholders’ approval for a buy-back plan should also be subject to legal ad-hoc disclosure requirements.

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 enableme 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.
Intangible assets as goodwill, licenses, research and development or customer relations become in high technology and service orientated economies more and more important. But comparing the book values of listed companies and their market capitalization the financial reports seems to fail the information needs of market participants regarding the estimate of the proper firm value. Moreover, with the introduction of Anglo-American accounting systems in Europe and Asia we can observe even in the accounts of companies sited in the same jurisdiction diverging accounting practices for intangible assets caused by different accounting standards. To assess the relevance of intangible assets in Japanese and German accounts of listed companies we therefore measure certain balance sheet and profit and loss relations according to goodwill and self-developed software. We compare and analyze valuation rules for goodwill and software costs according to German GAAP, Japanese GAAP, US GAAP and IAS to determine the possible impact of diverging rules in the comparability of the accounts. Our results show that the comparability of the accounts is impaired because of different accounting practices. The recognition and valuation of goodwill and self-developed software varies significantly according to the accounting regime applied. However, for the recognition of self-developed software, the effect on the average impact on asset coefficients or profit is not that high. Moreover, an industry bias can only be found for the financial industry. In contrast, for goodwill accounting we found major differences especially between German and Japanese Blue Chips. The introduction of the new goodwill impairment only approach and the prohibition of the pooling method may have a major impact especially for Japanese companies’ accounts.
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.
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.
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.
Ziel dieser Präsentation (anlässlich des Seminars „Die Auswirkungen von Asset Securitisation auf die Stabilität des Finanzmarktes“ Österreichische Nationalbank (ÖNB), Wien 1. Oktober 2003) ist es, eine Verbindung zwischen Verbriefung und Finanzmarkstabilität unter Berücksichtigung veränderter Finanzintermediation herzustellen. In der folgenden Abhandlung soll nun zunächst auf die Natur der Verbriefung per se eingegangen werden, um sodann anhand theoretischer Überlegungen und empirischer Beobachtungen mögliche Quelle systemischen Risikos in der Kreditverbriefung aufzuzeigen. In diesem Fall handelt es sich um die Informationsasymmetrien und die durch Handelbarkeit von Kreditrisiko bestimmte Transaktionsstruktur („security design“), die bei regulatorischer Nichtberücksichtigung eine destabilisierende Wirkung nicht nur im Bereich der Verbriefung, sondern auch hinsichtlich der gegenseitigen Zahlungsverpflichtungen von Finanzintermediären begründen könnte.
Asset-backed securitisation (ABS) is an asset funding technique that involves the issuance of structured claims on the cash flow performance of a designated pool of underlying receivables. Efficient risk management and asset allocation in this growing segment of fixed income markets requires both investors and issuers to thoroughly understand the longitudinal properties of spread prices. We present a multi-factor GARCH process in order to model the heteroskedasticity of secondary market spreads for valuation and forecasting purposes. In particular, accounting for the variance of errors is instrumental in deriving more accurate estimators of time-varying forecast confidence intervals. On the basis of CDO, MBS and Pfandbrief transactions as the most important asset classes of off-balance sheet and on-balance sheet securitisation in Europe we find that expected spread changes for these asset classes tends to be level stationary with model estimates indicating asymmetric mean reversion. Furthermore, spread volatility (conditional variance) is found to follow an asymmetric stochastic process contingent on the value of past residuals. This ABS spread behaviour implies negative investor sentiment during cyclical downturns, which is likely to escape stationary approximation the longer this market situation lasts.
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.
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.
This paper is focused on the coordination of order and production policy between buyers and suppliers in supply chains. When a buyer and a supplier of an item work independently, the buyer will place orders based on his economic order quantity (EOQ). However, the buyer s EOQ may not lead to an optimal policy for the supplier. It can be shown that a cooperative batching policy can reduce total cost significantly. Should the buyer have the more powerful position to enforce his EOQ on the supplier, then no incentive exists for him to deviate from his EOQ in order to choose a cooperative batching policy. To provide an incentive to order in quantities suitable to the supplier, the supplier could offer a side payment. One critical assumption made throughout in the literature dealing with incentive schemes to influence buyer s ordering policy is that the supplier has complete information regarding buyer s cost structure. However, this assumption is far from realistic. As a consequence, the buyer has no incentive to report truthfully on his cost structure. Moreover there is an incentive to overstate the total relevant cost in order to obtain as high a side payment as possible. This paper provides a bargaining model with asymmetric information about the buyer s cost structure assuming that the buyer has the bargaining power to enforce his EOQ on the supplier in case of a break-down in negotiations. An algorithm for the determination of an optimal set of contracts which are specifically designed for different cost structures of the buyer, assumed by the supplier, will be presented. This algorithm was implemented in a software application, that supports the supplier in determining the optimal set of contracts.
Die zunehmende Monopolisierung auf dem Markt für Informationsressourcen im akademischen Sektor führte in den vergangenen Jahren zu einer verstärkten Bildung von Bibliothekskonsortien auf der Abnehmerseite, die einen Gegenpol in Form einer Einkaufsgenossenschaft darstellen sollten [McCa02]. Diese Tendenzen lassen sich in verschiedenen Ländern wie etwa in Deutschland, England, der Schweiz und der Niederlande beobachten [Okerso]. In den USA sind Konsortien eher selten zu finden; das größte Konsortium ist hier OHIO-Link (http://www.lib.ohio-state.edu/). In Deutschland richten sich die meisten Konsortien wegen der föderalen Finanzierungsstrukturen regional aus; überregionale bzw. deutschlandweite Konsortien sind derzeit noch selten. Ein Zusammenschluss auf thematischer Grundlage findet derzeit so gut wie gar nicht statt, vielmehr werden möglichst viele Bibliotheken in Konsortien unabhängig von den an den jeweiligen Standorten betriebenen Forschungsschwerpunkten eingebunden [AnDe02]....
Elektronische Informationsressourcen, wie beispielsweise elektronische Zeitschriften und Datenbanken, gewannen in den letzten Jahren zunehmend an Bedeutung im Feld der akademischen Literaturversorgung. Mit diesem Trend einhergehend konnten Veränderungen der Bezugspraxis bei Bibliotheken einerseits und neue Preis- und Geschäftsmodelle bei Verlagen andererseits beobachtet werden. Neben der bequemeren Nutzbarkeit für die Leser bietet das neue Medium auch neue Formen des Kostencontrollings und der Optimierung für die Abnehmer. Dieser Workshop soll sich mit der Frage der Kostenrechnung und -verteilung für Konsortien für elektronische Informationsressourcen insbesondere eJournals beschäftigen. Dabei werden die neuen Möglichkeiten der Nutzungsmessung besonders berücksichtigt. Neben den theoretischen Ansätzen werden auch konkrete Beispielrechnungen durchgeführt und die Praktikabilität für die Umsetzung in der Praxis im besonderen Maße diskutiert.
Diese Arbeit untersucht empirisch den Zusammenhang von Beschäftigung und Lohnstrukturen zwischen sowie innerhalb von Qualifikations- und Altersgruppen. Zunächst werden Substitutionselastizitäten zwischen Qualifikations- und Altersgruppen geschätzt und die Lohnveränderungen bestimmt, die notwendig gewesen wären, um im Jahre 1997 die qualifikationsspezifischen Arbeitslosenquoten zu halbieren. Die geschätzten Substitutionselastizitäten sind sehr hoch. Die notwendige Lohnreduktion liegt nominal zwischen 9% und 10,6% und fällt umso höher aus, je geringer die Qualifikation der Arbeitnehmergruppe ist. Der zweite Teil der Arbeit befasst sich mit dem Zusammenhang zwischen residualer Lohnungleichheit und Beschäftigungsdynamik. Es werden konkurrierende Implikationen aus der Theorie der Grenzproduktivitätsentlohnung und der Suchtheorie abgeleitet und empirisch untersucht. Die Ergebnisse sind für keine der beiden Theorien überzeugend. Das robuste Ergebnis einer signifikant positiven Korrelation zwischen dem Niveau der Arbeitslosenquote und der residualen Lohnungleichheit legt allerdings nahe, dass Suchfriktionen zur Erklärung der residualen Lohndispersion beitragen können.

Despite the apparent stability of the wage bargaining institutions in West Germany, aggregate union membership has been declining dramatically since the early 90's. However, aggregate gross membership numbers do not distinguish by employment status and it is impossible to disaggregate these sufficiently. This paper uses four waves of the German Socioeconomic Panel in 1985, 1989, 1993, and 1998 to perform a panel analysis of net union membership among employees. We estimate a correlated random effects probit model suggested in Chamberlain (1984) to take proper account of individual specfic effects. Our results suggest that at the individual level the propensity to be a union member has not changed considerably over time. Thus, the aggregate decline in membership is due to composition effects. We also use the estimates to predict net union density at the industry level based on the IAB employment subsample for the time period 1985 to 1997. JEL - Klassifikation: J5
This paper is a draft for the chapter German banks and banking structure of the forthcoming book The German financial system . As such, the paper starts out with a description of past and present structural features of the German banking industry. Given the presented empirical evidence it then argues that great care has to be taken when generalising structural trends from one financial system to another. Whilst conventio nal commercial banking is clearly in decline in the US, it is far from clear whether the dominance of banks in the German financial system has been significantly eroded over the last decades. We interpret the immense stability in intermediation ratios and financing patterns of firms between 1970 and 2000 as strong evidence for our view that the way in which and the extent to which German banks fulfil the central functions for the financial system are still consistent with the overall logic of the German financial system. In spite of the current dire business environment for financial intermediaries we do not expect the German financial system and its banking industry as an integral part of this system to converge to the institutional arrangements typical for a market-oriented financial system.

Im Rahmen einer Ereignisstudie am deutschen Kapitalmarkt wird untersucht, ob Adhoc- Mitteilungen korrekt eingesetzt werden. Die Ergebnisse belegen, daß Nemax-50-Unternehmen die Veröffentlichung potentiell positiver Meldungsinhalte bevorzugen und die Bekanntmachung negativer Mitteilungen verzögern. Außerdem veröffentlichen Nemax-50-Werte in positiven Marktphasen besonders viele Mitteilungen und einen besonders hohen Anteil an positiven Meldungsinhalten, um von der positiven Stimmung der Marktteilnehmer zu profitieren. Dax-30-Werte verhalten sich dagegen regelgerecht. Die Befunde belegen die Notwendigkeit einer stärkeren Überwachung des Veröffentlichungsverhaltens der Emittenten, die in 2002 am Neuen Markt gelistet waren.
