A MANY-COUNTRY, MANY-GOOD MODEL OF LABOR MARKET RIGIDITIES AS A SOURCE OF COMPARATIVE ADVANTAGE
将Cuñat和Melitz（2007）的理论框架扩展到多国情境，发现劳动力市场更灵活的国家在波动性更大的行业具有比较优势。
We extend the theoretical framework in Cuñat and Melitz (2007) to a many-country setup where countries exhibit different degrees of labor market fexibility. We rely on the insights from a recent paper by Costinot (2009) to obtain precise predictions about comparative advantage in this setting: countries with more fexible labor markets specialize in more volatile industries.
