Regulation of International Financial Markets and International Banking
The research group ‘Regulation of International Financial Markets and International Banking’ analyses international capital flows as well as the consequences of regulatory changes for financial stability and intermediation. Both aspects can facilitate an efficient allocation of capital and enable risk sharing, but spark at the same time global financial instabilities. Banking regulation and supervision has accordingly changed significantly over recent years, but the impact of these comprehensive reforms on the functionality of the financial system remain unclear. In addition banks face further challenges, such as tightening monetary policy, geopolitical risks, and the emergence of new competitors due to digitalization.
Against this backdrop, the research group contributes to the literature in three ways. First, the group empirically analyses international capital flow determinants and the implications for financial stability and credit allocation. Periods characterised by a high degree of financial integration are often followed by financial crises, causing negative spill-overs to the real economy. This work package seeks to advance our understanding of how to maintain a stable banking system that is able to efficiently channel financial resources to firms and households alike.
Second, the group analyses the impact of changes in banking supervision and regulation on (inter)national activities of banks with a specific focus on the European integration process. The establishment of the European Banking Union constantly shapes the banking sector as prudential and regulatory responsibilities are transferred from the national to the Euro area level. Integrated markets allow for an early detection of soaring risks at an early stage, but new regulations can also create distortions. This work package contributes to the scant empirical evidence on this trade-off.
Third, “traditional” banks are not only operating in a tighter regulatory framework, they also face plenty of challenges threatening their business model and longer-term profitability. For example, increasing interest rates sparked deposit withdrawals and valuation losses of banks’ fixed income investment. Distortions due to the realization of political risks and rising levels of public, private, and corporate debt might bear the risk of future non-performing loans. The emergence of non-bank financial intermediaries (FinTech) challenge current business models of banks. The consequences for banks or their new competitors should be monitored.

IWH Data Project: International Banking Library
The International Banking Library is a web-based platform for the exchange of research on cross-border banking. It provides access to data sources, academic research, both theoretical and empirical, on cross-border banking, as well as information on regulatory initiatives. The International Banking Library addresses researchers, policymakers, and students of international banking and economics in search of comprehensive information on international banking issues.
The contents of the International Banking Library are summarised and distributed in a quarterly newsletter, thereby adding to the international visibility of the IWH (with more than 700 subscribers from academia, central banks and the industry) and facilitating a regular exchange of our research ideas with policy makers.
IWH Data Project: Financial Markets Directives Database
In Europe, financial markets have undergone significant regulatory changes since the last financial and sovereign debt crisis. One key element is the harmonisation of rules for capital regulation, bank resolution and deposit insurance. In the euro area, the sizable change in the regulatory framework is also reflected by the establishment of the European Banking Union.
Another change that might have implications for financial structure is the establishment of a Capital Market Union. Evidence-based policymaking and the evaluation of (un-)intended consequences of such reforms needs information on when regulatory changes happen. In the European Union, the cornerstones of regulatory changes that apply to all member states are implemented by means of regulations or directives. The latter ones have to be implemented, with some scope for discretion, into national law by the member states. The Financial Markets Directives Database assembles the dates at which countries have published the key legal document related to several recent directives affecting financial markets.
The cornerstone of the database constitutes information on the European Banking Union including its three directives on capital requirements, bank resolution and deposit insurance (CRD IV, BRRD, DGSD). The database has been made publically available via the website “International Banking Library” and is part of the Centre for Evidence-based Policy Advice (IWH-CEP).

Capital Controls and International Interest Rate Differentials
in: Applied Economics, 2010
Abstract
Since the Asian crises it is often taken as granted that capital markets have significant functional deficits. Often these deficits are believed to be so very strong that the ability of free capital markets to guarantee a more or less correct international allocation of capital is denied. It is argued that speculation dominates capital markets so much that capital allocation is purely random. This is one of the major arguments backing the present trend to re-establish capital controls, which emerged after the capital market distortions observed during the Asian flu. In the present article it is shown that capital markets, while certainly prone to many distortions, are well capable of roughly guiding capital to the proper place. Though allocation is not model-like perfect, this steals the thunder from the idea, that closed or government-guided capital markets were able to perform better.

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.
