 abstract = {In this paper, we test some propositions about international trade flows that are derived from a model of monopolistic competition developed by Elhanan Helpman. We investigate whether the volume of trade between OECD countries is consistent with the predictions of a modal in which all trade is intra-industry trade in differentiated products. We then repeat the test with non-OECD countries. We also investigate whether the share of intra-industry trade is consistent with a more general theoretical model in which some, but not all, trade is intra-industry trade. Our results lead us to question the apparent empirical success of these models.},
