We propose several connectedness measures built from pieces of variance decompositions, and we argue that they provide natural and insightful measures of connectedness among financial asset returns and volatilities. We also show that variance decompositions define weighted, directed networks, so...

We examine banking competition when deposit or loan contracts contingent on macroeconomic shocks become feasible. We show that the risk allocation is efficient, provided that banks are not bailed out. In this case, banks may shift part of the risk to depositors. The private sector insures the...

Rating agencies state that they take a rating action only when it is unlikely to be reversed shortly afterwards. Based on a formal representation of the rating process, I show that such a policy provides a good explanation for the empirical evidence: Rating changes occur relatively seldom,...

Under a new Basel capital accord, bank regulators might use quantitative measures when evaluating the eligibility of internal credit rating systems for the internal ratings based approach. Based on data from Deutsche Bundesbank and using a simulation approach, we find that it is possible to...

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 describe a general equilibrium model with a banking system in which the deposit bank collects deposits from households and the merchant bank provides funds to firms. Merchant banks borrow collateralized short-term funds from deposit banks. In a financial downturn, as the value of collateral...

Foreign currency loans to the unhedged non-banking sector are remarkably prevalent in Europe and create a significant exchange-rate-induced credit risk to European banking sectors. In particular, Swiss franc (CHF)-denominated loans, popular in Eastern European countries, could trigger...

We estimate a Pareto distribution for loan losses, as an alternative to the commonly used Vasicek distribution, using simulated data. A key assumption in the construction of Vasicek distribution is that firm-level risk is idiosyncratic. It also assumes that firm exposure to systemic risk is...
