Regulation of International Financial Markets and Banking
The research group "Regulation of International Financial Markets and Banking" analyzes international capital flows and the effects of regulatory changes on financial stability. Financial integration promotes efficient capital allocation and risk sharing but also eases the transmission of shocks across borders.
Banking regulation has accordingly evolved in recent years, yet the full impact of these reforms remains unclear. Hence, the group focuses on two areas:
First, it investigates the drivers of international capital flows and their effects on financial stability. Periods of high financial integration often precede crises with lasting real-economy consequences. The aim is to understand how to ensure stable and effective credit allocation.
Second, it examines how changes in regulation and supervision influence cross-border banking, especially within the context of European integration. This includes evaluating the balance between regulatory harmonization and unintended market distortions.
Two data projects support this research: the International Banking Library, a web-based platform for research exchange with a quarterly newsletter reaching more than 700 subscribers, and the Financial Markets Directives Database, which documents the implementation of key EU financial regulations with a special focus on the European Banking Union. Together, they promote evidence-based policymaking and enhance the group's global visibility.

Does It Pay to Get Connected? An Examination of Bank Alliance Network and Bond Spread
in: Journal of Economics and Business, forthcoming
Abstract
This paper examines the effects of bank alliance network on bonds issued by European banks during the period 1990–2009. We construct six measures capturing different dimensions of banks’ network characteristics. In opposition to the results obtained for non-financial firms, our findings indicate that being part of a network does not create value for bank’s bondholders, indicating a dark side effect of strategic alliances in the banking sector. While being part of a network is perceived as a risk-increasing event by market participants, this negative perception is significantly lower for the larger banks, and, to a lesser extent, for the more profitable banks. Moreover, during crisis times, the positive impact on bond spread of a bank’s higher centrality or of a bank’s higher connectedness in the network is stronger, indicating that market participants may fear spillover effects within the network during periods of banks’ heightened financial fragility.
Social Capital and Accounting Conservatism
in: Journal of International Accounting, Auditing and Taxation, Vol. 60 (June), 2026
Abstract
We investigate the relationship between county-level social capital in the U.S. and asymmetric earnings timeliness (accounting conservatism). We measure social capital by the strength of civic norms and the density of social networks in a community. We find that firms headquartered in regions with higher social capital have earnings that reflect bad news more quickly than good news. Two potential mechanisms driving this connection are evident in our findings. First, the positive link between social capital and asymmetric earnings timeliness is more pronounced in firms with weaker external oversight, suggesting that social capital compensates for weaknesses in these mechanisms by discouraging managers from delaying the recognition of bad news. Second, we illustrate that firms in high social capital regions are more likely to recruit senior executives with higher asymmetric earnings timeliness coefficients. This result implies a preference for managers who adopt more conservative accounting practices. We find similar results using an international sample of firms from 21 countries. Our findings offer new insights into how local social norms influence corporate financial reporting.
Social Capital and Retail Investor Behavior: Evidence From the Corporate Social Irresponsibility Shocks in Taiwan
in: Journal of International Financial Markets, Institutions and Money, Vol. 108 (April), 2026
Abstract
In this paper, we use granular trading data from Taiwan between 2012 and 2016 to examine how local social capital influences retail investor behavior during corporate social irresponsibility (CSIR) events. Therefore, we are responding to longstanding calls in the international finance literature to explore investor behavior in non-US markets with distinct institutional and cultural characteristics. We find that investors residing in cities with higher social capital are less likely to purchase underpriced stocks following the announcements of negative events despite the potential for positive abnormal returns. This norm-driven restraint reflects a form of socially responsible investing motivated by community-based values rather than economic rationality. By documenting this behavior in an East Asian market, we extend the external validity of social norm theories developed in Western settings and contribute to a more nuanced understanding of how localized social preferences can influence asset pricing and capital allocation in a global context.
Aggregate Dynamics with Sectoral Price Stickiness Heterogeneity and Aggregate Real Shocks
in: Journal of Money, Credit and Banking, Vol. 57 (5), 2025
Abstract
This paper investigates the relationship between heterogeneity in sectoral price stickiness and the response of the economy to aggregate real shocks. We show that sectoral heterogeneity reduces inflation persistence for a constant average duration of price spells, and that inflation persistence can fall despite duration increases associated with increases in heterogeneity. We also find that sectoral heterogeneity reduces the persistence and volatility of interest rate and output gap for a constant price spells duration, while the qualitative impact on inflation volatility tends to be positive. A relevant policy implication is that neglecting price stickiness heterogeneity can impair the economic dynamics assessment.
How Do EU Banks’ Funding Costs Respond to the CRD IV? An Assessment Based on the Banking Union Directives Database
in: Journal of Financial Stability, Vol. 78 (June), 2025
Abstract
The establishment of the European Banking Union constitutes a major change in the regulatory framework of the banking system. Main parts are implemented via directives that show staggered transposition timing across EU member states. Based on the newly compiled Banking Union Directives Database, we assess how banks’ funding costs responded to the Capital Requirements Directive IV (CRD IV). Our findings show an upward trend in funding costs which is driven by an increase in cost of equity and partially offset by a decline in cost of debt. The diverging trends are most present in countries with an ex-ante lower regulatory capital stringency, which is in line with banks’ short-run adjustment needs but longer-run benefits from increased financial stability.

Friend or Foe? Crowdfunding Versus Credit when Banks are Stressed
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
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.
