Firms in International Trade : Trade Policy Implications of the New New Trade Theory
This paper explores the implications of recent developments in firm-based trade theory and empirics for trade policy and negotiations. While traditional trade theory focused on the country, and the new trade theory of the 1980’s adopted the industry as the unit for analysis, the newest theory emphasizes the role of firms and firm heterogeneity in international trade. We describe insights from this reformulation of theory and the empirical literature that illuminates it. The realities of trade as now understood show the need for a new new trade policy. Evaluating trade at the level of the firm implies that overcoming firm-level fixed costs of trade and reducing uncertainty lead to increased trade along margins that generate the highest productivity, innovation, and welfare gains. The traditional market access agenda ought now to be less important on the multilateral agenda than services, standards, trade facilitation, procurement, and innovation policy. The analytical needs of a new new trade policy require new models and more access to firm-level data to formulate and evaluate the multi-faceted impacts of trade policy
