This paper studies the role of the Community Reinvestment Act (CRA) in the recent US housing boom-bust cycle. Using a difference-in-differences matching estimation, I find that the enhancement of CRA enforcement in 1998 caused a 7.7 percentage points increase in annual growth rate of mortgage lending by CRA-regulated banks to CRA-eligible census tracts relative to a group of similar-income CRA-ineligible census tracts within the same state. Financial institutions which are not subject to the CRA, however, do not show any change in their mortgage supply between these two types of census tracts after 1998. I take advantage of this exogenous shift in mortgage supply within an instrumental variable framework to identify the causal effect of mortgage supply on housing prices. I find that every 1 percentage point higher annual growth rate of mortgage supply leads to 0.3 percentage points higher annual growth rate of housing prices. Reduced form regressions show that CRA-eligible neighborhoods experienced higher house price growth during the boom and sharper decline during the bust period. I use placebo tests to confirm that this effect is in fact channeled through the shift in mortgage supply by CRA-regulated banks and not by unobserved demand factors. Furthermore, my results indicate that CRA-induced mortgages went to borrowers with lower FICO scores, carried higher interest rates, and encountered more frequent delinquencies.

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.

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.

We analyze the inward and outward transmission of regulatory changes through German banks’ (international) loan portfolio. Overall, our results provide evidence for international spillovers of prudential instruments, these spillovers are however quite heterogeneous between types of banks and can only be observed for some instruments. For instance, foreign banks located in Germany reduce their loan growth to the German economy in response to a tightening of sector-specific capital buffers, local reserve requirements and loan to value ratios in their home country. Furthermore, from the point of view of foreign countries, tightening reserve requirements was effective in reducing lending inflows from German banks. Finally, we find that business and financial cycles matter for lending decisions.

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.

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.
