Mit einem Paneldatensatz für sämtliche niedersächsischen Industriebetriebe der Jahre 1995 bis 2002 werden drei Hypothesen aus dem Modell von Hopenhayn (Econometrica 1992) getestet: (H1) Firmen, die in der Periode t aus dem Markt ausscheiden, waren in der Periode t-1 weniger produktiv als...

Using a knowledge production framework and a rich set of plant level data this study demonstrates that in Germany firms that are active on international markets as exporters or foreign direct investors do generate more new knowledge than firms which sell on the national market only. These...

This paper presents the first empirical test with German establishment level data of a hypothesis derived by Helpman, Melitz and Yeaple in a model that explains the decision of heterogeneous firms to serve foreign markets either trough exports or foreign direct investment: only the more...

This paper presents the first nonparametric test whether German works councils go hand in hand with higher labor productivity or not. It distinguishes between establishments that are covered by collective bargaining or not. Results from a Kolmogorov-Smirnov test for first order stochastic...

Using OLS and quantile regression methods and rich cross-section data sets for western and eastern Germany, this paper demonstrates that the impact of works council presence on labor productivity varies between manufacturing and services, between plants that are or are not covered by collective...

Mikroökonometrische Studien mit Firmendaten aus vielen Ländern zeigen, dass exportierende Firmen eine höhere Produktivität aufweisen als Firmen, die lediglich den jeweiligen Binnenmarkt ihres Sitzlandes beliefern, und dass es einen Selbstselektionsprozess der produktiveren Firmen auf...

Many plant-level studies find that average wages in exporting firms are higher than in non-exporting firms from the same industry and region. This paper uses a large set of linked employer-employee data from Germany to analyze this exporter wage premium. We show that the wage differential...

A recent survey of 54 micro-econometric studies reveals that exporting firms are more productive than non-exporters. On the other hand, previous empirical studies show that exporting does not necessarily improve productivity. One possible reason for this result is that most previous studies are...

Using unique recently released nationally representative high-quality longitudinal data at the enterprise level for Germany, this paper presents the first comprehensive evidence on the relationship between exports and profitability. It documents that the positive profitability differential of...
