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.

This article investigates to what extent the composition of exports is related to the export performance of eurozone countries using a data set on exports from the oldest eurozone countries to their top 20 trade partners for the period 1988-2009. The results suggest that a higher share of high technology exports in total exports is positively related to total exports. Export composition also conditions the effects of the real exchange rate and partner income growth. The effect of the real exchange rate on exports becomes smaller the higher the share of high technology exports in total exports. The effect of partner income on exports becomes larger the higher the share of high technology exports in total exports. Adapted from the source document.

We use Spanish firm-level data over the period 1998-2018 to examine the importance of the top exporter in terms of NUTS III (provincial) exports. We find that: (1) the top exporter in each province represents about one fifth of total exports per year; (2) firms contribute to export growth whilst on their way towards the top position but once the latter is reached their growth contribution becomes marginal; and (3), shocks to the top exporter of a province explain the fluctuations in aggregate exports growth.
