Export Behavior and Firm productivity in German Manufacturing. A Firm-Level Analysis

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 postulated by the recent literature on international trade with heterogeneous firms. In estimating productivity, we control for a possible simultaneity bias by using semiparametric estimation techniques. Moreover, we apply a matching technique in order to analyze whether the presence in international markets enabled firms to achieve further productivity improvements, without finding significant evidence for this. We conclude that high-productivity firms self-select themselves into export markets, while exporting itself does not play a significant role for productivity improvements.
