Diversity and Trade
构建了一个竞争模型，研究禀赋相似国家间的贸易模式，发现劳动力才能分布的差异决定贸易方向，并分析了贸易对收入分配和企业构成的影响。
We develop a competitive model of trade between countries with similar aggregate factor endowments. The trade pattern reflects differences in the distribution of talent across the labor forces of the two countries. The country with a relatively homogeneous population exports the good produced by a technology with complementarities between tasks. The country with a more diverse workforce exports the good for which individual success is more important. Imperfect observability of talent strengthens the forces of comparative advantage. Finally, we examine the effects of trade on income distribution and the composition of firms in each industry.
