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

The Distorting Impact of Capital Controls
in: German Economic Review, Nr. 1, 2012
This paper uses panel data to show that capital controls have a significant impact on international interest rate differentials. Various types of controls can be distinguished within the data. The analysis shows that the aforementioned effects of capital controls on interest rates are especially strong in the case of capital import controls on portfolio capital; the implementation of these controls has been suggested in the wake of the Asian Crisis to prevent further crises. The results presented herein contradict the hypothesis that capital controls can achieve a restructuring of the maturity of capital inflows without a distortion in international capital allocation.
Protect and Survive? Did Capital Controls Help Shield Emerging Markets from the Crisis?
in: Economics Bulletin, Nr. 1, 2012
Using a new dataset on capital market regulation, we analyze whether capital controls helped protect emerging markets from the real economic consequences of the 2009 financial and economic crisis. The impact of the crisis is measured by the 2009 forecast error of a panel state space model, which analyzes the business cycle dynamics of 63 middle-income countries. We find that neither capital controls in general nor controls that were specifically targeted to derivatives (that played a crucial role during the crisis) helped shield economies. However, banking regulation that limits the exposure of banks to global risks has been highly successful.
The Impact of Fixed Exchange Rates on Fiscal Discipline
in: Scottish Journal of Political Economy, Nr. 5, 2011
In this paper, it is shown that, contrary to standard arguments, fiscal discipline is not substantially enhanced by a fixed exchange rate regime. This study is based on data from 116 countries collected from 1975 to 2004 and uses various estimation techniques for dynamic panel data, in particular a GMM estimation in the tradition Arellano and Bover (1995) and Blundell and Bond (1998). Contrary to previous papers on this topic, the present paper takes into account that the consequences of a new exchange rate regime do not necessarily fully manifest immediately.
The Role of Rating Agencies in Financial Crises: Event Studies from the Asian Flu
in: Cambridge Journal of Economics, 2010
Based on case studies from countries that have been hit hardest by the Asian financial crisis of 1997, the present paper shows that the accusation that sovereign ratings led to a severe acceleration of the crisis is unconvincing and that the empirical method often used to support accusations against rating agencies is inappropriate for the problem under analysis. Rather, it must be emphasised that ratings were downgraded in most countries very shortly before the end of the crisis. In some countries, the ratings were even further downgraded after the end of the crisis as countries started to recover. This is not in line with the thesis that the crisis was accelerated by rating agencies.
Capital Controls and International Interest Rate Differentials
in: Applied Economics, 2010
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.
Explaining Regional Disparities in Housing Prices across German Districts
in: IZA Institute of Labor Economics, March 2022
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.
