Unequal Effects of Trade on Workers with Different Abilities
研究贸易如何影响不同能力工人的工资和失业率，发现中等能力工人在开放经济中平均工资下降、失业率上升，而低能力和高能力工人受影响较小。
In recent research, we have proposed a new framework for examining the determinants of income inequality, which emphasizes firm and worker heterogeneity and selection into export markets. In this paper, we use our framework to examine how wage inequality and unemployment vary across workers with different abilities. Both in the closed and open economy, the unemployment rate is decreasing in worker ability, whereas both the average wage and wage inequality are increasing in worker ability. Upon opening the economy to trade, however, intermediate-ability workers experience reductions in average wages and increases in unemployment rates relative to both lower and higher ability workers.
