Abstract
Bank efficiency estimates often serve as a proxy of managerial skill since they quantify sub-optimal production choices. But such deviations can also be due to omitted systematic differences among banks. In this study, we examine the effects of heterogeneity on bank efficiency scores. We compare different specifications of a stochastic cost and alternative profit frontier model with a baseline specification. After conducting a specification test, we discuss heterogeneity effects on efficiency levels, ranks and the tails of the efficiency distribution. We find that heterogeneity controls influence both banks’ optimal costs and profits and their ability to be efficient. Differences in efficiency scores are important for more than only methodological reasons. First, different ways of accounting for heterogeneity result in estimates of foregone profits and additional costs that are significantly different from what we infer from our general specification. Second, banks are significantly re-ranked when their efficiency is estimated with a specification other than the preferred, general specification. Third, the general specification gives the most reliable estimates of the probability of distress, although differences to the other specifications are low.

Bank Regulation and Supervision in Bank-dominated Financial Systems: A Comparison between Japan and Germany

European Journal of Law and Economics,
2009
Abstract
This paper compares bank regulation and supervision in Japan and Germany. We consider these countries because they both have bank-dominated financial systems and their banking systems are often lumped together as one model, yet, bank stability differs significantly. We show that Japan and Germany have chosen different approaches to bank regulation and supervision and ask why they made their choices. We argue that bank regulation and supervision were less efficient in Japan than in Germany and that these differences were decisive for bank behavior.

Are there Gender-specific Preferences for Location Factors? A Grouped Conditional Logit-model of Interregional Migration Flows in Germany

IWH Discussion Papers,
No. 5,
2009
Abstract
The article analyses the question whether women and men differ in their tastes for location factors. The question is answered by quantifying the impact of location characteristics on interregional migration flows across Germany. The analysis is based on a grouped conditional logit approach. We augment the framework by controlling for violation of the independence of irrelevant alternatives assumption and for overdispersion. As a result, we find no differences in terms of direction of impact. However, the regressions confirm gender differences in terms of intensity, particularly regarding regional wage levels and the availability of educational institutions.

Analysis of location of large-area shopping centres - A probalistic gravity model for the Halle-Leipzig area

Jahrbuch für Regionalwissenschaft,
No. 1,
2007
Abstract
A profund analysis of large-area shopping centres from the perspective of retail, but also of communes is of importance for the choice of site selection. In central Germany, the Halle–Leipzig area represents an example of strong competitiveness between the different participants in retail. The analysis described in this article is based on the MCI Model of Nakanishi and Cooper, which is used to investigate the regional influences of nine large shopping centres in the area of interest. The analysis demonstrates, that the studied shopping centres intensely affect the structure of retail in the region and exert a strong influence on the structural weakness of the surrounding cities due to their relative success in comparison to other retail locations city centres. An important volume of the turnover of the administrative districts flows to the analysed shopping centres. On the other hand, the article describes the influence of a systematic location decision on the reachable turnover potential of the modelized large-area shopping centres among each other. The shopping centres Saale Park (today Nova Eventis) near Leipzig and the Paunsdorf Center in Leipzig show the biggest influence on the competing centres.

Local Taxes and Capital Structure Choice

Abstract
This paper investigates the question of taxation and capital structure choice in Germany. Germany represents an excellent case study for investigating the question of whether and to what extent taxes influence the debt-equity decision of firms, because the relative tax burdens on debt and equity vary greatly across communities. German communities levy local taxes on profits and long-term debt payments in addition to personal and corporate taxes on the federal level. A stylized model is presented incorporating these taxes. The model shows that local taxes create substantial incentives for firms to use debt financing. Furthermore, the paper empirically investigates the effect of local business taxes on the share of debt used to finance incremental investments by German firms. I find that local taxes significantly influence the capital structure choice of firms, controlling for a large number of other factors. In an extensive sensitivity analysis the tax effect are found to be robust across several different specifications.
