Wir untersuchen Übernahmen deutscher Unternehmen zwischen 1985 und 1993 im Hinblick auf ihren Einfluß auf den Marktwert des Käufers. In Erweiterung bisheriger Studien analysieren wir insbesondere, welche Ereignisse den größten Informationsgehalt haben und damit zu den deutlichsten...

If one abstracts from specially organized markets like stock or commodity exchanges, (international) trade relies on bargaining between the interested parties. Whereas earlier the results of bargaining were seen as unpredictable or determined by an at most vaguely defined concept of (relative)...

East-West migration in Germany peaked at the beginning of the 90s although the average wage gap between Eastern and Western Germany continues to average about 25%. We analyze the propensity to migrate using microdata from the German Socioeconomic Panel. Fitting a parametric Generalized Linear...

Spatial joins are join operations that involve spatial data types and operators. Spatial access methods are often used to speed up the computation of spatial joins. This paper addresses the issue of benchmarking spatial join operations. For this purpose, we first present a WWW-based tool to...

Likelihood ratio (LR) tests for the cointegrating rank of a vector autoregressive (VAR) process have been developed under different assumptions regarding deterministic terms. For instance, nonzero mean terms and linear trends have been accounted for in some of the tests. In this paper we provide...

Motivated by a hedging problem in mathematical finance, El Karoui and Quenez [7] and Kramkov [14] have developed optional versions of the Doob-Meyer decomposition which hold simultaneously for all equivalent martingale measures. We investigate the general structure of such optional...

We investigate the relative merits of a moment-oriented bootstrap method of Bunke (1997) in comparison with the classical wild bootstrap of Wu (1986) in nonparametric heteroscedastic regression situations. The moment-oriented bootstrap is a wild bootstrap based on local estimators of higher...
