This paper uses a static and dynamic gravity model of trade to investigate the link between German development aid and exports from Germany to the recipient countries. The findings indicate that in the long run,German aid is associated with an increase in exports of goods that is larger than the...

Using data from Germany, Japan, UK, and the U.S., we explore possible threshold cointegration in nominal short- and long-run interest rates with corresponding inflation rates. Traditional cointegration implies perfect mean reversion in real rates and hence confirms the Fisher hypothesis....

The empirical joint distribution of return-pairs on stock indices displays high tail-dependence in the lower tail and low tail-dependence in the upper tail. The presence of tail-dependence is not compatible with the assumption of (conditional) joint normality. The presence of asymmetric-tail...

This paper questions traditional approaches for testing the day-of-the-week effect on stock returns. We propose an alternative approach based on the closure test principle introduced by Marcus, Peritz and Gabriel (1976), which has become very popular in Biometrics and Medical Statistics. We test...

In this paper we study the sources of wage growth. We identify the contribution to such growth of general, sector specific and firm specific human capital. Our results are interpretable within the context of a model where the returns to human capital may be heterogeneous and where firms may...

The German Environmental Liability Law (ELL) of 1991 has introduced far-reaching civil liability for environmental damages with the aim to increase firms? efforts to prevent accidents. Previous studies find poor evidence that this goal has actually been achieved. One and a half decades after the...

Das Handwerk gilt in Hinblick auf den Umsatz und die Beschäftigung als Konjunkturstabilisator. Dieser Einschätzung widersprechen allerdings verschiedene wissenschaftliche Untersuchungen. Welche Kräfte hier prozyklisch und welche antizyklisch wirken, lässt sich durch eine...

The aim of this paper is to analyze and estimate salient characteristics of unemployment dynamics. Movements in unemployment are viewed as "chain reactions" of responses to labour market shocks, working their way through systems of interacting lagged adjustment processes. In the context of...
