Results from portfolio models for credit risk tell us that loan concentration in certain industry sectors can substantially increase the value-at-risk (VaR). The purpose of this paper is to analyze whether a tractable infection modelʺ can provide a meaningful estimate of the impact of...

Modern trade theory emphasizes firm-level productivity differentials to explain the cross-border activities of non-financial firms. This study tests whether a productivity pecking order also determines international banking activities. Using a novel dataset that contains all German banks’...

Recent developments on international financial markets have called the benefits of bank globalization into question. Large, internationally active banks have acquired substantial market power, and international activities have not necessarily made banks less risky. Yet, surprisingly little is...

Lending specialization on certain industry sectors can have opposing effects on monitoring (including screening) abilities and on the sectoral concentration risk of a credit portfolio. In this paper, we examine in the first part if monitoring abilities of German cooperative banks and savings...

The purpose of this paper is to measure the potential impact of business-sector concentration on economic capital for loan portfolios and to explore a tractable model for its measurement. The empirical part evaluates the increase in economic capital in a multi-factor asset value model for...

This paper provides new evidence on the foreign direct investment stocks of German firms. We use firm-level data for the years 1990-2000 to describe the regional and sectoral patterns of German FDI through gravity-type equations. We provide evidence on the patterns of FDI by sector, by size of...

Does more FDI make the world a riskier place for workers? We analyze whether an increase in multinational firms' activities is associated with an increase in firm-level employment volatility. We use a firm-level dataset for Germany which allows us to distinguish between purely domestic firms,...

This paper studies the sectoral and geographical dimensions of the response of bank lending to sectoral growth. We use several bank-level datasets provided by the Deutsche Bundesbank for the 1996-2002 period. Our results show that bank heterogeneity affects how lending responds to domestic...

From a theoretical point of view, greater trade openness affects firm-level volatility by changing the exposure and the reaction of firms to macroeconomic shocks. The net effect is ambiguous, though. This paper provides firm-level evidence on the link between openness and volatility. Using two...
