This article addresses the differences in margins across exporting and nonexporting firms. We jointly estimate a translog cost function, a variable factor share equation and price-cost margin equations to analyse the effect of persistence in export activity on margins. Results indicate that nonexporters have smaller margins than persistent exporters and firms that entered foreign markets during the nineties. However, larger export ratio is negatively associated with margins for persistent exporters. It suggests that efficiency advantages for exporters are partially compensated by higher competitive pressure in international markets. These results are in accordance with the predictions of Melitz and Ottaviano (2005 Melitz, MJ and Ottaviano, GIP. 2005. Market size trade, and productivity, NBER Working Paper Series No. 11393 (forthcoming in The Review of Economic Studies) [Google Scholar]).
