Intermediation and Economic Integration
指出国际贸易理论长期忽视市场制度，而现实中中介在实现贸易收益中起核心作用，并展示了一个中介模型来说明其如何促进贸易收益的实现。
The theory of international trade has paid scant attention to market institutions. Neither neoclassical theory nor new trade models typically specify the process by which supply and demand meet. Yet in the real world, intermediaries play a central role in materializing the gains from exchange outlined by standard trade theories. In Antr’and Costinot (2010), we have developed a stylized but explicit model of intermediation in trade. In this short paper, we present a variant of this model that illustrates the potential role of intermediaries in facilitating the realization of the gains from trade.
