- Messung individueller Risikoeinstellungen (1997)
- Es werden verschiedene Methoden zur Messung der Risikoeinstellung einzelner Individuen vorgestellt und kritisch diskutiert. Berücksichtigt werden unter anderem Selbsteinschätzungen und experimentell orientierte Verfahren. Die Zusammenstellung wendet sich insbesondere an Wissenschaftler und Praktiker, die nach anwendbaren Verfahren zur Risikoeinstellungsmessung suchen.
- Performance and market share : evidence from the German mutual fund industry (1997)
- In this paper we analyze the relation between fund performance and market share. Using three performance measures we first establish that significant differences in the risk-adjusted returns of the funds in the sample exist. Thus, investors may react to past fund performance when making their investment decisions. We estimated a model relating past performance to changes in market share and found that past performance has a significant positive effect on market share. The results of a specification test indicate that investors react to risk-adjusted returns rather than to raw returns. This suggests that investors may be more sophisticated than is often assumed.

- Finanzierungstheorie: Ein selektiver Überblick (1998)
- Seit zwanzig Jahren befaßt sich die Finanzmarktforschung einerseits mit Fragen der Bewertung und des Managements von Finanztiteln auf effizienten Kapitalmärkten und mit Fragen der Managementkontrolle auf unvollkommenen Märkten. Der folgende selektive Überblick konzentriert sich auf zentrale Aspekte der Theorie und Empirie der Managementkontrolle bei asymmetrischer Information. Ziel ist die Auseinandersetzung mit der unlängst vorgetragenen These zu den Mythen der Unternehmenskontrolle (Martin Hellwig 1997). Der aktuelle Überblick wird entwickelt vor dem Hintergrund der Gutenberg’schen Position eines eigenständigen Unternehmensinteresses, losgelöst von den Interessen der shareholder oder anderer stakeholder. Diese Position von Gutenberg verbindet sich im dritten Band der „Grundlagen der BWL: Die Finanzen“ von 1969 mit der Forderung nach Einhaltung eines sog. finanziellen Gleichgewichts. Erst in jüngster Zeit werden auch kapitalmarkttheoretisch fundierte Modelle entwickelt, die auch Raum bieten für eine Autonomie des Managements gegenüber dessen stakeholders.
- Where do we stand in the theory of finance? : a selective overview with reference to Erich Gutenberg (1998)
- For the past 20 years, financial markets research has concerned itself with issues related to the evaluation and management of financial securities in efficient capital markets and with issues of management control in incomplete markets. The following selective overview focuses on key aspects of the theory and empirical experience of management control under conditions of asymmetric information. The objective is examine the validity of the recently advanced hypothesis on the myths of corporate control. The present overview is based on Gutenberg's position that there exists a discrete corporate interest, as distinct from and separate from the interests of the shareholders or other stakeholders. In the third volume of Grundlagen der BWL: Die Finanzen, published in 1969, this position of Gutenberg's is coupled with an appeal for a so-called financial equilibrium to be maintained. Not until recently have models grounded in capital market theory been developed which also allow for a firm's management to exercise autonomy vis-à-vis its stakeholder. This paper was prepared for the Erich Gutenberg centenary conference on December 12 and 13, 1997 in Cologne.
- Is relationship lending special? : Evidence from credit-file data in Germany (1998)
- The German financial market is often characterized as a bank-based system with strong bank-customer relationships. The corresponding notion of a housebank is closely related to the theoretical idea of relationship lending. It is the objective of this paper to provide a direct comparison between housebanks and "normal" banks as to their credit policy. Therefore, we analyze a new data set, representing a random sample of borrowers drawn from the credit portfolios of five leading German banks over a period of five years. We use credit-file data rather than industry survey data and, thus, focus the analysis on information that is directly related to actual credit decisions. In particular, we use bank-internal borrower rating data to evaluate borrower quality, and the bank's own assessment of its housebank status to control for information-intensive relationships.
- Collateral, default risk, and relationship lending : an empirical study on financial contracting (1999)
- This paper provides further insights into the nature of relationship lending by analyzing the link between relationship lending, borrower quality and collateral as a key variable in loan contract design. We used a unique data set based on the examination of credit files of five leading German banks, thus relying on information actually used in the process of bank credit decision-making and contract design. In particular, bank internal borrower ratings serve to evaluate borrower quality, and the bank's own assessment of its housebank status serves to identify information-intensive relationships. Additionally, we used data on workout activities for borrowers facing financial distress. We found no significant correlation between ex ante borrower quality and the incidence or degree of collateralization. Our results indicate that the use of collateral in loan contract design is mainly driven by aspects of relationship lending and renegotiations. We found that relationship lenders or housebanks do require more collateral from their debtors, thereby increasing the borrower's lock-in and strengthening the banks' bargaining power in future renegotiation situations. This result is strongly supported by our analysis of the correlation between ex post risk, collateral and relationship lending since housebanks do more frequently engage in workout activities for distressed borrowers, and collateralization increases workout probability.

- Information production in credit relationships : on the role of internal ratings in commercial banking (2000)
- This paper discusses the role of internal corporate ratings as a means by which commercial banks condense their informational advantage and preserve it vis-à-vis a competitive lending market. In drawing on a unique data set collected from leading universal banks in Germany, we are able to evaluate the extent to which non-public information determines corporate ratings. As a point of departure, the paper describes a sample of rating systems currently in use, and points at methodological differences between them. Relying on a probit analysis, we are able to show that the set of qualitative, or soft, factors is not simply redundant with respect to publicly available accounting data. Rather, qualitative information tends to be decisive in at least one third of cases. It tends to improve the firms' overall corporate rating. In the case of conflicting rating changes, i.e. when qualitative and quantitative rating changes have opposing signs, quantitative criteria dominate the overall rating change. Furthermore, the more restrictive the weighting scheme as part of the rating methodology is, the stronger is the impact of qualitative information on the firms' overall rating. The implications of our results underline the need to define stringent rating standards, from both a risk management and a regulatory point of view.

- Generally accepted rating principles: a primer : [This version: February 14, 2000] (2000)
- Bank internal ratings of corporate clients are intended to quantify the expected likelihood of future borrower defaults. This paper develops a comprehensive framework for evaluating the quality of standard rating systems. We suggest a number of principles that ought to be met by 'good rating practice'. These 'generally accepted rating principles' are potentially relevant for the improvement of existing rating systems. They are also relevant for the development of certification standards for internal rating systems, as currently discussed in a consultative paper issued by the Bank for International Settlement in Basle, entitled 'A new capital adequacy framework'. We would very much appreciate any comments by readers that help to develop these rating standards further. Simply send us an E-mail, or give us a call.
- Corporate debt restructuring : evidence on lender coordination in financial distress (2001)
- In the recent theoretical literature on lending risk, the coordination problem in multi-creditor relationships have been analyzed extensively. We address this topic empirically, relying on a unique panel data set that includes detailed credit-file information on distressed lending relationships in Germany. In particular, it includes information on creditor pools, a legal institution aiming at coordinating lender interests in borrower distress. We report three major findings. First, the existence of creditor pools increases the probability of workout success. Second, the results are consistent with coordination costs being positively related to pool size. Third, major determinants of pool formation are found to be the number of banks, the distribution of lending shares, and the severity of the distress shock.
