The Network Structure of International Trade
基于法国企业出口动态的实证发现，提出贸易摩擦的新理论：企业通过直接搜索和现有联系人网络远程寻找贸易伙伴，并刻画了出口商国际网络的形成过程。
Motivated by empirical evidence I uncover on the dynamics of French firms' exports, I offer a novel theory of trade frictions. Firms export only into markets where they have a contact. They search directly for new trading partners, but also use their existing network of contacts to search remotely for new partners. I characterize the dynamic formation of an international network of exporters in this model. Structurally, I estimate this model on French data and confirm its predictions regarding the distribution of the number of foreign markets accessed by exporters and the geographic distribution of exports.
