Abstract

A recent survey of 54 micro-econometric studies reveals that exporting firms are more productive than non-exporters. However, previous empirical studies show that exporting does not necessarily improve productivity. One possible reason for this result is that most previous studies are restricted to analysing the relationship between a firmís export status and the growth of its labour productivity, using the firmsí export status as a binary treatment variable and comparing the performance of exporting and non-exporting firms. In this paper, we apply the newly developed generalised propensity score (GPS) methodology that allows for continuous treatment, that is, different levels of the firmsí export activities. Using the GPS method and a large panel data set for German manufacturing firms, we estimate the relationship between a firmís export-sales ratio and its labour productivity growth rate. We find that there is a causal effect of firmsí export activities on labour productivity growth. However, exporting improves labour productivity growth only within a sub-interval of the range of firmsí export-sales ratios.
