The breakdown of the interbank money markets in the face of the recent financial crisis has forced central banks and governments to take extraordinary measures to sustain financial stability. In this paper we investigate which influence central bank activity has on interbank markets. In our...

This paper explores the economics of interbank lending and borrowing using bank-balance sheet data for Germany, the largest European economy. Our 2002 - 2014 panel data set allows us to analyze the cross section and the dynamics of the observed interbank exposures. Our findings suggest a genuine...

In this paper, we report a descriptive investigation of the structural evolution of two of the most important over-the-counter markets for liquidity in Germany: the interbank market for credit and for derivatives. We use end-of-quarter data from the German large credit register between 2002 and...

We examine the effect of ex-post information contagion on the ex-ante level of systemic risk defined as the probability of joint default of banks. Because of counterparty risk or common exposures, bad news about one bank reveals valuable information about another bank and trigger information...

Emerging markets are characterized by frequent periods of large and unexpected exchange rate depreciations. These events create opportunities for foreign investors to purchase domestic assets at a discount, especially if these assets have sticky prices. We show this to be the case in the housing...

Consistent with theoretical predictions, we show that investors incorporate expected joint liquidation costs in their portfolio decisions. Using detailed security-level holdings of U.S. Money Market Mutual Funds (MMFs), we construct a new measure of portfolio similarity among investors and show...

Formal collaboration between researchers via co-authorship has been shown to have a positive impact on academic productivity. But most academic collaboration is informal, e.g. in the form of commentary on research papers. We present and discuss a novel dataset on informal collaboration in...

Banks face different but potentially correlated risks from outside the financial system. Financial connections can share these risks, but they also create the means by which shocks can be propagated. We examine this tradeoff in the context of a new stylized fact we present: German banks are more...

When banks choose similar investment strategies the financial system becomes vulnerable to common shocks. We model a simple financial system in which banks decide about their investment strategy based on a private belief about the state of the world and a social belief formed from observing the...
