Earnings Inequality and the Minimum Wage: Evidence from Brazil
结合行政和调查数据与巴西劳动力市场均衡模型，发现1996至2018年间实际最低工资上涨128%对工资分布产生广泛溢出效应，解释了同期收入不平等大幅下降的45%，且对就业和产出的影响因工人向高生产率企业再配置而减弱。
Increases in the minimum wage can substantially reduce earnings inequality. To demonstrate this, we combine administrative and survey data with an equilibrium model of the Brazilian labor market. We find that a 128 percent increase in the real minimum wage in Brazil between 1996 and 2018 had far-reaching spillover effects on wages higher up in the distribution. The increased minimum wage accounts for 45 percent of a large fall in earnings inequality over this period. At the same time, the effects of the minimum wage on employment and output are muted by reallocation of workers toward more productive firms..
