Abstract: A key distinction which has emerged from heterogeneous firm models of international trade is that of exporting at the intensive and extensive margins. Empirically however, the two are often conflated, leading to biased estimates of the impact of falling trade costs. This paper exploits detailed firm level data, which includes information on the destination of exports to investigate causal links between enterprise productivity and the number of markets a firm serves as well as the relative size of those markets. Our focus is Sweden’s Food and Beverage sector, which is not only highly open, but has been subject to policy induced changes in trade costs (as well as falling natural barriers) over our sample period. We have data on almost 10,000 firm / time / destination observations across 6 years and 138 destinations. Our results confirm that conflating adjustment at the internal and external margins does bias trade resistance effects. Combining detailed firm specific information with data on destination characteristics confirms the importance of a range of country specific characteristics (including exchange rate risk) and facilitates the estimation of both distance and market size elasticities, from firm level data.
