Anknüpfend an den ersten gelungenen IWH-FIN-FIRE Workshop im Jahr 2015 fand am 8. und 9. September 2016 in den Räumen des IWH in Halle (Saale) zum zweiten Mal der vom IWH sowie dem „FIRE“ Research Center der Frankfurt School of Finance & Management gemeinschaftlich organisierte Workshop statt.

The global financial crisis of 2007-08 and its adverse effects on economic activity have put financial stability back on the agenda of both researchers and policymakers. The regulatory debate has since then revolved around the question which reforms are needed to effectively reduce the likelihood and costs of future systemic financial crises. By now, the debate has led to an update of regulatory frameworks on the national, European, and global level. This thesis contributes to the empirical research on the risks to financial stability and to the debate on the regulation of international financial markets. It builds on some of the key insights from the recent global financial crisis and the respective policy responses. Chapter 1 of the thesis analyzes the reasons behind the strong co-movements of credit risk in sovereign bond markets during the financial crisis and the subsequent euro area debt crisis. In addition, it investigates to what extent high co-movements might be the outcome of contagion and through which channels contagion occurs. Chapter 2 investigates how uncertainty in banking affects banks’ loan supply, and it analyzes if the lending behavior is heterogeneous across different types of banks. Turning to the analysis of actual policies, Chapter 3 studies the effect of liquidity provided by the Eurosystem on macroeconomic adjustment in European crisis countries. Finally, Chapter 4 of the thesis assesses the effectiveness of a macroprudential policy instrument, caps on banks’ leverage, in stabilizing credit growth during financial downturns.

Bank distress can have severe negative consequences for the stability of the financial system. Regimes for the restructuring and resolution of banks, financed by bank levies, aim at reducing these costs. This paper evaluates the German bank levy, which has been implemented since 2011. Our analysis offers three main insights. First, revenues raised through the levy were lower than expected. Second, the bulk of the payments were contributed by large commercial banks and by the central institutions of savings banks and credit unions. Third, for those banks, which were affected by the levy, we find evidence for a reduction in lending and higher deposit rates.

We study the impact of national politics on default risk of eurozone banks as measured by the stock market-based Distance to Default. We find that national electoral cycles, the power of the government as well as the government’s party ideological alignment significantly affect the stability of banks in the eurozone member countries. Moreover, we show that the impact of national politics on bank default risk is more pronounced for large as well as weakly capitalized banks.

Die deutsche Wirtschaft befindet sich nach wie vor in einem moderaten Aufschwung. Der anhaltende Beschäftigungsaufbau führt zu spürbaren Einkommenssteigerungen, und der Fall der Energiepreise hat die Kaufkraft der privaten Haushalte deutlich erhöht. Beides treibt den privaten Konsum, aber auch die Wohnungsbauinvestitionen, welche überdies von den sehr niedrigen Zinsen beflügelt werden. Allerdings bleiben die Exporte angesichts der schwachen internationalen Dynamik in diesem und im nächsten Jahr eher verhalten. Alles in allem dürfte das deutsche Bruttoinlandsprodukt in diesem Jahr um 1,8% und im Jahr 2017 um 1,6% zunehmen.

In a proposed model of a multinational bank, interest margins determine local lending by foreign affiliates and the internal funding by parent banks. We exploit detailed parent-affiliate-level data of all German banks to empirically test our theoretical predictions in pre-crisis times. Local lending by affiliates depends negatively on price margins, the difference between lending and deposit rates in foreign markets. The effect of funding cost margins, the gap between local deposit rates faced by affiliates abroad and the funding costs of their parents, on internal capital market funding is positive but statistically weak. Interest margins are central to explain the interaction between internal capital markets and foreign affiliates lending.

We investigate the determinants of sovereign bond holdings of German banks and the implications of such holdings for bank risk. We use granular information on all German banks and all sovereign debt exposures in the years 2005–2013. As regards the determinants of sovereign bond holdings of banks, we find that these are larger for weakly capitalized banks, banks that are active on capital markets, and for large banks. Yet, only around two thirds of all German banks hold sovereign bonds. Macroeconomic fundamentals were significant drivers of sovereign bond holdings only after the collapse of Lehman Brothers. With the outbreak of the sovereign debt crisis, German banks reallocated their portfolios toward sovereigns with lower debt ratios and bonds with lower yields. With regard to the implications for bank risk, we find that low-risk government bonds decreased the risk of German banks, especially for savings and cooperative banks. Holdings of high-risk government bonds, in turn, increased the risk of commercial banks during the sovereign debt crisis.

„Der Finanzplatz London wird trotz Brexit seine dominante Position in Europa behalten. Das hat zum einen die Einführung des Euro gelehrt, liegt aber auch an den maßgeblichen Standortfaktoren Londons: der Größe der Stadt, der regulatorischen Umgebung und dem Humankapital“, so Professor Reint E. Gropp, Präsident des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH).

Unternehmerische Aktivität ist ein dynamischer Treiber wirtschaftlicher Entwicklung. Finanzmarktwissen befähigt Individuen zu einer besseren Abwägung von Chancen und Risiken. In diesem Beitrag wird geprüft, ob ein höheres Maß an Finanzmarktwissen auch einen Einfluss auf die Entscheidung hat, sich selbstständig zu machen. Dieser Zusammenhang wird auf der Basis von Umfragedaten für Deutschland empirisch bestätigt.
