Sektorale Investitionsentwicklung und Liquiditätseinfluß. Eine Längsschnitts-Querschnitts-Untersuchung für den Unternehmenssektor der Bundesrepublik Deutschland Die vorliegende empirische Arbeit stellt einen Beitrag zur aktuellen Diskussion um die Bedeutung der Liquidität für das...

The paper explores the investment behaviour of German firms in the context of the Qapproach, which plays a dominant role in empirical investment research. The analysis is based on the Deutsche Bundesbank's corporate balance sheet statistics. The panel data set contains some 2,300 German firms'...

In our analysis we discuss several dynamic panel data estimators proposed in the literature and assess their performance in Monte Carlo simulations. It is a well known fact that the natural choice, the least squares dummy variable estimator is biased in the context of dynamic estimation. The...

Banks face a tradeoff between diversifying and focusing their loan portfolio. In this paper we carry out an empirical study for the German market to shed light on the question whether or not the benefits of risk sharing outweigh those of specialization. We use data from the Bundesbank's...

The question of whether or not mergers and acquisitions have helped to enhance banks' efficiency and profitability has not yet been conclusively resolved in the literature. We argue that this is partly due to the severe methodological problems involved. In this study, we analyze the effect of...

The stochastic frontier analysis (Aigner et al., 1977, Meeusen and van de Broeck, 1977) is widely used to estimate individual efficiency scores. The basic idea lies in the introduction of an additive error term consisting of a noise and an inefficiency term. Most often the assumption of a...

We suggest a new parametric approach to estimate the extent of downward nominal wage rigidity in ten European countries between 1994 and 2001. The data base used throughout is the User Data Base (UDB) of the European Community Household Panel (ECHP). The proposed approach is based on the very...

We analyse differences between the wage distributions in the USA and Germany in 2001 both for women and men. The empirical analysis is based on the decomposition of differences using Cox's marginal (partial) likelihood. The approach based on rank invariant estimators such as Cox's is borrowed...

Evidence on female firm leadership is scarce and often confined to a small number of firms included in share price indices. Our large firm level data set from 2011 contains 441287 firms from 14 EU states. Based on management information, we provide evidence for the extent and the performance of...

We analyze the effect of local supplier and customer densities on employment growth, using a sample of 19 275German firms. We suggest a new approach to estimating firm-specific customer and supply densities through combining input-output data from the German Federal Statistical Office and...
