In many situations the applied researcher wants to combine different data sources without knowing the exact link and merging rule. This paper introduces a theoretical framework how two different regional administrative data sources can be merged. It presents different merging schemes based on...

This paper explores the potential of an approach suggested by Manski of obtaining nonparametric bounds for treatment effects in evaluation studies without knowledge of the participation process. The practical concern is the effects of continuous vocational training in East Germany. The empirical...

In this paper we investigate the effects of region and industry?wide spillovers from foreign direct investment (FDI) on the volumes of export of Ukrainian manufacturing firms, using unpublished panel data from 1996?2000. Economic theory suggests that FDI has direct and indirect effects on firm?s...

This paper analyses the relationship between firm productivity and export behavior in German manufacturing firms. We examine whether productivity increases the probability of exporting, and assert that there is a causal relationship from high productivity to entering foreign markets, as...

For small high-tech firms international orientation is regarded as crucial for growth and long-term survival. Even newly founded technology based firms (NTBFs) are often internationally active shortly after their inception (?born globals?). However, in order to create jobs and have a sustainable...

Using the model recently developed by Jaumandreu (2003) this paper reports new results on the relationship between innovation and employment growth in Germany. The model is tailor-made for analysing firm-level employment effects of innovations using specific information provided by CIS data. It...

International engagement is often expected to improve firm performance. Especially for small technology-oriented firms, export activities may be important, being regarded as one way to amortise these firms? high product research and development costs. This paper examines the relationship between...

This paper tests some of the predictions of recent advances in trade theory that have focused on different trade patterns of firms within the same sector. Helpman, Melitz and Yeaple (2005) develop a model in which innate productivity differences between firms determine the degree of...
