Regulierung internationaler Finanzmärkte und Banken
Diese Forschungsgruppe analysiert Ursachen und Konsequenzen von internationalen Aktivitäten von Banken sowie den regulatorischen Rahmen, innerhalb dessen globale Banken operieren.
International aktive Banken können eine effiziente internationale Kapitalallokation vereinfachen und zur internationalen Risikoteilung beitragen. Allerdings können sie auch Instabilitäten generieren und zu einer Übertragung von Schocks über nationale Grenzen hinaus beitragen. Dies ist einer der Gründe für die aktuelle Re-Regulierung des internationalen Bankensystems.
Die Forschungsgruppe trägt auf drei verschiedenen Wegen zur Literatur bei. Erstens analysiert die Gruppe empirisch, warum internationale Banken global aktiv sind und wie Schocks im Finanzsystem übertragen werden. Zweitens untersucht die Gruppe das Entstehen von systemischen Risiken und Ungleichgewichten im integrierten Bankenmarkt und die sich daraus ergebenden Konsequenzen für die Realwirtschaft. Drittens werden die Auswirkungen von Änderungen bezüglich der Bankenaufsicht und Bankenregulierung analysiert, mit einem besonderen Fokus auf dem europäischen Integrationsprozess

Interactions Between Bank Levies and Corporate Taxes: How is Bank Leverage Affected?
in: Journal of Banking and Finance, Nr. 105874, September 2020
Abstract
Regulatory bank levies set incentives for banks to reduce leverage. At the same time, corporate income taxation makes funding through debt more attractive. In this paper, we explore how regulatory levies affect bank capital structure, depending on corporate income taxation. Based on bank balance sheet data from 2006 to 2014 for a panel of EU-banks, our analysis yields three main results: The introduction of bank levies leads to lower leverage as liabilities become more expensive. This effect is weaker the more elevated corporate income taxes are. In countries charging very high corporate income taxes, the incentives of bank levies to reduce leverage turn insignificant. Thus, bank levies can counteract the debt bias of taxation only partially.

Financial Incentives and Loan Officer Behavior: Multitasking and Allocation of Effort under an Incomplete Contract
in: Journal of Financial and Quantitative Analysis, Nr. 4, 2020
Abstract
We investigate the implications of providing loan officers with a nonlinear compensation structure that rewards loan volume and penalizes poor performance. Using a unique data set provided by a large international commercial bank, we examine the main activities that loan officers perform: loan prospecting, screening, and monitoring. We find that when loan officers are at risk of losing their bonuses, they increase prospecting and monitoring. We further show that loan officers adjust their behavior more toward the end of the month when bonus payments are approaching. These effects are more pronounced for loan officers with longer tenures at the bank.

Banks’ Equity Performance and the Term Structure of Interest Rates
in: Financial Markets, Institutions and Instruments, Nr. 2, 2020
Abstract
Using an extensive global sample, this paper investigates the impact of the term structure of interest rates on bank equity returns. Decomposing the yield curve to its three constituents (level, slope and curvature), the paper evaluates the time-varying sensitivity of the bank’s equity returns to these constituents by using a diagonal dynamic conditional correlation multivariate GARCH framework. Evidence reveals that the empirical proxies for the three factors explain the variations in equity returns above and beyond the market-wide effect. More specifically, shocks to the long-term (level) and short-term (slope) factors have a statistically significant impact on equity returns, while those on the medium-term (curvature) factor are less clear-cut. Bank size plays an important role in the sense that exposures are higher for SIFIs and large banks compared to medium and small banks. Moreover, banks exhibit greater sensitivities to all risk factors during the crisis and postcrisis periods compared to the pre-crisis period; though these sensitivities do not differ for market-oriented and bank-oriented financial systems.

The Dilemma of International Diversification: Evidence from the European Sovereign Debt Crisis
in: Asia-Pacific Journal of Financial Studies, Nr. 2, 2020
Abstract
This paper tests how capital markets value the international diversification of banks in good and in bad economic times by investigating changes in domestic and foreign sovereign debt ratings before and during the European sovereign debt crisis. Tracing 320 European banks in 29 countries and 226 credit rating announcements for European sovereigns between 1 January 2001 and 15 August 2012, we show that the market values banks with access to foreign funds. Despite occasional adverse effects immediately following negative news regarding sovereign credit rating changes, international diversification was found to be beneficial to European banks, especially during periods of distress.

Cross-border Transmission of Emergency Liquidity
in: Journal of Banking and Finance, April 2020
Abstract
We show that emergency liquidity provision by the Federal Reserve transmitted to non-U.S. banking markets. Based on manually collected holding company structures, we identify banks in Germany with access to U.S. facilities. Using detailed interest rate data reported to the German central bank, we compare lending and borrowing rates of banks with and without such access. U.S. liquidity shocks cause a significant decrease in the short-term funding costs of the average German bank with access. This reduction is mitigated for banks with more vulnerable balance sheets prior to the inception of emergency liquidity. We also find a significant pass-through in terms of lower corporate credit rates charged for banks with the lowest pre-crisis leverage, US-dollar funding needs, and liquidity buffers. Spillover effects from U.S. emergency liquidity provision are generally confined to short-term rates.

Explaining Regional Disparities in Housing Prices across German Districts
in: IZA Institute of Labor Economics, March 2022
Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.
