This article contributes to the literature by examining product-level dynamics within firms in the context of Mexican trade integration under NAFTA. The data show intense product churning within firms and confirm the existence of within-firm product heterogeneity. The data indicate that new exporters enter foreign markets with a small number of varieties, most of which were previously sold at home, and with a small export small volume. The data also suggest that export discoveries are relatively rare and are imitated within a short period of time.ENFirm Behavior: Empirical Analysis D220Multinational FirmsInternational Business F230Production, Pricing, and Market StructureSize Distribution of Firms L110Production Management M110Journal ArticleWorld Bank
