This paper provides an update of de Nardis and Vicarelli (2003) estimates of the euro effect on trade integration of EMU economies, taking into account aggregate bilateral exports of 23 OECD countries for the sample period 1988-2003. In this paper we utilize the dynamic panel data estimator proposed by Blundell and Bond (1998) and introduce controls for heterogeneity. The results of our dynamic specification of the gravity equation lead to an estimate of the intra-Eurozone pro-trade effect, following the adoption of the single currency, as high as around 4%. This finding, slightly lower than our previous work results, is in line with very recent empirical literature using dynamic specification of gravity equation. It is also consistent with the already tight trade links characterizing the economies that embraced the euro and with the possibility that the trade impact involved the introduction of new goods rather than the expansion, due to lower transaction costs, of the incumbent products
