Matching and Inequality in the World Economy
开发了分析多商品多要素经济中要素配置与价格决定的方法，给出了罗伊式分配模型中稳健单调比较静态的充分条件，并用于揭示全球化的新影响。
This paper develops tools and techniques to analyze the determinants of factor allocation and factor prices in economies with a large number of goods and factors. The main results of our paper characterize suf-ficient conditions for robust monotone comparative statics predictions in a Roy-like assignment model. These general results are then used to generate new insights about the consequences of globalization. I.
