We explore the impact of large banks and of financial openness for aggregate growth. Large banks matter because of granular effects: if markets are very concentrated in terms of the size distribution of banks, idiosyncratic shocks at the bank-level do not cancel out in the aggregate but can...

The global financial crisis has brought to an end a rather unprecedented period of banks' international expansion. We analyze the effects of the crisis on international banking. Using a detailed dataset on the international assets of all German banks with foreign affiliates for the years...

Does the mere presence of big banks affect macroeconomic outcomes? Gabaix (2011) shows that idosyncratic shocks can have aggregate effects if the distribution of firm sizes in manufacturing follows a power law distribution. Our contribution is two-fold. First, we expand the theory of granularity...

There is growing consensus that the conduct of monetary policy can have an impact on stability through the risk-taking incentives of banks. Falling interest rates might induce a 'search for yield' and generate incentives to invest into risky activities. This paper provides evidence on the link...

The World Financial Crisis has shaken the fundamentals of international banking and triggered a downward spiral of asset prices. To prevent a further meltdown of markets, governments have intervened massively through rescues measures aimed at recapitalizing banks and through liquidity support....

The German banking market is notorious for its low degree of market penetration by foreign financial institutions, suggesting that markets serviced by domestic and foreign banks are segmented. This paper employs a number of tests to determine whether activities of domestic and foreign banks are...

One key focus of the on-going debate on the integration of international financial markets have been measures to lengthen the maturity of foreign debt. Short-term debt is typically considered to be volatile and thus a potential trigger of currency crises. In contrast to the vivid policy debate...

There is growing consensus that the conduct of monetary policy can have an impact on financial and economic stability through the risk-taking incentives of banks. Falling interest rates might induce a 'search for yield' and generate incentives to invest into risky activities. This paper provides...

The interplay between banks and the macroeconomy is of key importance for financial and economic stability. We analyze this link using a factor-augmented vector autoregressive model (FAVAR) which extends a standard VAR for the U.S. macroeconomy. The model includes GDP growth, inflation, the...
