ABSTRACTThe main focus of this paper is the relationship between export diversification and export performance. The key difference with respect to the previous literature is that export diversification is measured and related to export volume by destination country. The approach is empirical and an aggregate export demand setting is adopted to test the significance and influence of export diversification, measured via the Herfindahl index, on export performance by destination country. The econometric estimation is performed using export data for Spain to its partner countries for the period 1999–2011. The main finding is the positive relationship between Spanish export concentration and export performance by destination market. This finding is shown to be robust to several econometric specifications.

This paper contributes to the flourishing literature on exports and productivity by using a unique newly available panel of exporting establishments from the manufacturing sector of Germany from 1995 to 2004 to test three hypotheses derived from a theoretical model by Hopenhayn (Econometrica 1992): (H1) Firms that stop exporting in year t were in t-1 less productive than firms that continue to export in t. (H2) Firms that start to export in year t are less productive than firms that export both in year t-1 and in year t. (H3) Firms from a cohort of export starters that still export in the last year of the panel were more productive in the start year than firms from the same cohort that stopped to export in between. While results for West Germany support all three hypotheses, this is only the case for (H1) and (H2) in East Germany.
