The Basel Committee plans to differentiate risk-adjusted capital requirements between banks regulated under the internal ratings based (IRB) approach and banks under the standard approach. We investigate the consequences for the lending capacity and the failure risk of banks in a model with endogenous interest rates. The optimal regulatory response depends on the banks' inclination to increase their portfolio risk. If IRB-banks are well-capitalized or gain little from taking risks, then they will increase their market share and hold safe portfolios. As risk-taking incentives become more important, the optimal portfolio size of banks adopting intern rating systems will be increasingly constrained, and ultimately they may lose market share relative to banks using the standard approach. The regulator has only limited options to avoid the excessive adoption of internal rating systems. JEL Klassifikation: K13, H41.
A widely recognized paper by Colin Mayer (1988) has led to a profound revision of academic thinking about financing patterns of corporations in different countries. Using flow-of-funds data instead of balance sheet data, Mayer and others who followed his lead found that internal financing is the dominant mode of financing in all countries, that financing patterns do not differ very much between countries and that those differences which still seem to exist are not at all consistent with the common conviction that financial systems can be classified as being either bank-based or capital market-based. This leads to a puzzle insofar as it calls into question the empirical foundation of the widely held belief that there is a correspondence between the financing patterns of corporations on the one side, and the structure of the financial sector and the prevailing corporate governance system in a given country on the other side. The present paper addresses this puzzle on a methodological and an empirical basis. It starts by comparing and analyzing various ways of measuring financial structure and financing patterns and by demonstrating that the surprising empirical results found by studies that relied on net flows are due to a hidden assumption. It then derives an alternative method of measuring financing patterns, which also uses flow-of-funds data, but avoids the questionable assumption. This measurement concept is then applied to patterns of corporate financing in Germany, Japan and the United States. The empirical results, which use an estimation technique for determining gross flows of funds in those cases in which empirical data are not available, are very much in line with the commonly held belief prior to Mayer’s influential contribution and indicate that the financial systems of the three countries do indeed differ from one another in a substantial way, and moreover in a way which is largely in line with the general view of the differences between the financial systems of the countries covered in the present paper.
Zweiter Band der zweiten Fassung (B) der "Römischen Octavia". Verzeichnet im Ostermesskatalog von 1713. Cf. zur vollständigen Publikationsgeschichte: Octavia römische Geschichte, [vol. 1] (Nürnberg: J. Hoffmann, 1677). Enthält mehrere teils wahrscheinlich, teils sicher autorfremde Gedichte. Zwei davon stammen von Christian Hofmann von Hofmannswaldau (vgl. HKA I, pp. CLXXIVf., Anm. 195). Gegenüber der ersten Fassung nur geringere Überarbeitung. Neu hinzugekommen ist "Fortsetzung der Geschichte/ Des Königs Monobazes und der Königin Susanna von Adiabene", pp. 808-855. Von der "Geschichte der Flavia Domitilla und der Cönis", pp. 920-1015, existiert eine Übersetzung einer unbekannten französischen Hofdame ins Französische, datiert auf den 9. März 1714 (23: Cod.Guelf. 196.1 Extravag.).
This paper analyzes empirically the distribution of unemployment durations in West- Germany before and after the changes during the mid 1980s in the maximum entitlement periods for unemployment benefits for elderly unemployed. The analysis is based on the comprehensive IAB employment subsample containing register panel data for about 500.000 individuals in West Germany. We analyze two proxies for unemployment since the data do not precisely measure unemployment in an economic sense. We provide a theoretical analysis of the link between the durations of nonemployment and of unemployment between jobs. Our empirical analysis finds significant changes in the distributions of nonemployment durations for older unemployed individuals. At the same time, the distribution of unemployment durations between jobs did not change in response to the reforms. Our findings are consistent with an interpretation that many firms and workers used the more bene cial laws as a part of early retirement packages but those workers who were still looking for a job did not reduce their search effort in response to the extension of the maximum entitlement periods. This interpretation is consistent with our theoretical model under plausible assumptions. JEL: C24, J64, J65
Thema dieser Arbeit ist eine ökonomische Einordnung der Förderung der beruflichen Weiterbildung (FbW) als Teil der Aktiven Arbeitsmarktpolitik in Deutschland. Die Analyse erfolgt im Lichte des sektoralen Wandel, der Verschiebung der qualifikatorischen Arbeitsnachfrage und der vorrauszusehenden Produktivitätseffekte im Zusammenhang mit einer alternden Gesellschaft. Auf Basis der Humankapitaltheorie wird zunächst theoretisch erörtert, inwieweit sich FbW als Teil der Aktiven Arbeitsmarktpolitik aus Effizienz- und Verteiliungsgesichtspunkten rechtfertigen lässt und in welcher Form FbW sinnvoll sein kann.
This paper evaluates the effects of Public Sponsored Training in East Germany in the context of reiterated treatments. Selection bias based on observed characteristics is corrected for by applying kernel matching based on the propensity score. We control for further selection and the presence of Ashenfelter's Dip before the program with conditional difference-in-differences estimators. Training as a first treatment shows insignificant effects on the transition rates. The effect of program sequences and the incremental effect of a second program on the reemployment probability are insignificant. However, the incremental effect on the probability to remain employed is slightly positive. JEL - Klassifikation: H43 , C23 , J6 , J64 , C14
Unter dem Stichwort "Patchwork-Biografien" wird die Tatsache, dass ein großer Teil der abhängig Beschäftigten ihren erlernten Beruf nicht mehr ausüben, in jüngster Zeit viel diskutiert. Diese Studie liefert einen empirischen Beitrag zur Anatomie der Berufswechsel für westdeutsche Männer auf Basis der BIBB/IABDaten 1998/1999. Als Grundlage für die empirische Analyse wird ein theoretisches Modell der Wahl zwischen horizontal differenzierten Berufen entwickelt. Die wichtigsten Ergebnisse sind: Ex post beobachtete Berufswechsel hängen negativ vom Durchschnittslohn im Ausbildungsberuf und positiv vom Durchschnittslohn im Erwerbsberuf ab. Der deskriptiv beobachtete durchschnittliche Entlohnungseffekt eines Berufswechsels ist signifikant positiv, verstärkt sich noch, wenn für den Ausbildungsberuf kontrolliert wird, und ist demgegenüber signifikant negativ, wenn für den Erwerbsberuf kontrolliert wird. Der geschätzte kausale durchschnittliche Entlohnungseffekt ist positiv. Die Ergebnisse sind insgesamt damit konsistent, dass Berufswechsel vor allem damit zusammenhängen, dass Beschäftigte im neuen Erwerbsberuf größere Verdienst- und Karrierechancen wahrnehmen können.

The Box-Cox quantile regression model using the two stage method introduced by Chamberlain (1994) and Buchinsky (1995) provides an attractive extension of linear quantile regression techniques. However, a major numerical problem exists when implementing this method which has not been addressed so far in the literature. We suggest a simple solution modifying the estimator slightly. This modification is easy to implement. The modified estimator is still [square root] n-consistent and its asymptotic distribution can easily be derived. A simulation study confirms that the modified estimator works well.
