Trade, Labor Market Frictions, and Residual Wage Inequality across Worker Groups
利用巴西雇主-雇员匹配数据，研究贸易自由化对不同教育水平工人群体残差工资不平等的差异化影响，发现高教育工人工资离散度增幅更大。
Using a matched employer-employee data set, we study the effects of trade liberalization on wage dispersion in Brazil across heterogeneous worker groups, keeping in mind that the assignment of workers to firms may be non-random and determined by the time-invariant productivity of workers specific to the firms with which they are matched. We find differential effects of trade reform on residual wage inequality across worker groups. High education workers experience greater increases in wage dispersion relative to low education workers following trade liberalization. This finding is broadly consistent with the theoretical predictions that emerge from models with heterogeneous firms, heterogeneous workers, and labor market frictions.
