Regulation of International Financial Markets and International Banking

This research group analyses causes and consequences of banks' international activities and the regulatory framework they operate in.

Internationally active banks can facilitate an efficient international allocation of capital and provide channels for international risk sharing. But they can also be a source of financial instabilities themselves, thus contributing to international contagion and risk-shifting. This is one reason for the current re-regulation of international banking.

The research group contributes to the literature in three ways. First, the group empirically analyses the channels through which shocks are transmitted by internationally active banks. Second, the group analyses the build-up of aggregate imbalances in integrated banking markets and resulting consequences for the real economy. Third, the group analyses the impact of changes in banking supervision and regulation on (inter)national activities of banks, with a special focus on the European integration process.

Finance and Wealth Inequality

Iftekhar Hasan Roman Horvath Jan Mares

in: Journal of International Money and Finance, November 2020

Abstract

Using a global sample, this paper investigates the determinants of wealth inequality capturing various economic, financial, political, institutional, and geographical indicators. Using instrumental variable Bayesian model averaging, it reveals that only a handful of indicators robustly matters and finance plays a key role. It reports that while financial depth increases wealth inequality, efficiency and access to finance reduce inequality. In addition, redistribution and education are associated with lower inequality whereas wars and openness to international trade contribute to greater wealth inequality.

Do Conventional Monetary Policy Instruments Matter in Unconventional Times?

Manuel Buchholz Kirsten Schmidt Lena Tonzer

in: Journal of Banking and Finance, No. 105874, September 2020

Abstract

This paper investigates how declines in the deposit facility rate set by the ECB affect euro area banks’ incentives to hold reserves at the central bank. We find that, in the face of lower deposit rates, banks with a more interest-sensitive business model are more likely to reduce reserve holdings and allocate freed-up liquidity to loans. The result is driven by banks in the non-GIIPS countries of the euro area. This reveals that conventional monetary policy instruments have limited effects in restoring monetary policy transmission during times of crisis.

Interactions Between Bank Levies and Corporate Taxes: How is Bank Leverage Affected?

Franziska Bremus Kirsten Schmidt Lena Tonzer

in: Journal of Banking and Finance, No. 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

Patrick Behr Alejandro H. Drexler Reint E. Gropp Andre Guettler

in: Journal of Financial and Quantitative Analysis, No. 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.

Cross-border Transmission of Emergency Liquidity

Thomas Kick Michael Koetter Manuela Storz

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.

Friend or Foe? Crowdfunding Versus Credit when Banks are Stressed

Daniel Blaseg Michael Koetter

in: IWH Discussion Papers, No. 8, 2015

Abstract

Does bank instability push borrowers to use crowdfunding as a source of external finance? We identify stressed banks and link them to a unique, manually constructed sample of 157 new ventures seeking equity crowdfunding. The sample comprises projects from all German equity crowdfunding platforms since 2011, which we compare with 200 ventures that do not use crowdfunding. Crowdfunding is significantly more likely for new ventures that interact with stressed banks. Innovative funding is thus particularly relevant when conventional financiers are facing crises. But crowdfunded ventures are generally also more opaque and risky than new ventures that do not use crowdfunding.

Explaining Regional Disparities in Housing Prices across German Districts

Lars Brausewetter Stephan L. Thomsen Johannes Trunzer

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.
