Adverse Selection in Labor Markets and International Trade
研究了因逆向选择导致劳动力市场扭曲的国家间的贸易，发现自由贸易可能使劣势国家受损，而补贴进口品生产可改善其社会福利。
This analysis considers trade between countries with labor-market distortions due to adverse selection. Comparative advantage is caused either by a better mix of high and low productivity workers or by the absence of adverse selection in one country. In either case, free trade may lead to a loss for the inferior country. A trading equilibrium is Pareto better than an equilibrium in a fully integrated economy with perfect factor mobility if both countries face adverse selection, otherwise the trading equilibrium is Pareto inferior. Subsidies for production of the imported good may improve the social utility of the 'inferior' country. Copyright 1995 by The editors of the Scandinavian Journal of Economics.
