Feenstra and Ma (2008) develop a monopolistic competition model where firms choose their optimal product scope by balancing the profits from a new variety against the costs of "cannibalizing" sales of existing varieties. While more productive firms always have a higher market share, there is no...

We examine how foreign ownership of a firm affects the variety of goods that the firm exports and the number of countries it trades with. We construct a simple theoretical model of how foreign ownership may affect these extensive margins of exports and take this model to data from Germany, one...

This paper uses micro-data fromtheWorld Bank Investment Climate Surveys 2002-2006 to investigate how foreign ownership and access to external finance affect the likelihood of manufacturers in emerging markets to export and/or import. Applying propensity score matching to control for differences...

This paper uses unique new data for German manufacturing enterprises from matched regular surveys and a special purpose survey to investigate the causal effect of relocation of activities to a foreign country on various dimensions of firm performance. Enterprises that relocated activities abroad...

A stylized fact from the emerging literature on the micro-econometrics of international trade and a central implication of the heterogeneous firm models from the new new trade theory is that exporters are more productive than non-exporters. However, many firms from the lower end of the...

This note uses a new tailor-made data set to investigate the link between firm age and the extensive margins of imports empirically for the first time for Germany. Results turn out to be fully in line with the theoretical considerations. Older firms are more often importers, import more...

This paper uses an approach recently suggested by Gabaix (Eonometrica 2011) to investigate for the first time the role of idiosyncratic shocks to the largest firms in the dynamics of imports by firms from manufacturing industries. For Germany we find evidence that imports are power-law...

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...
