Supply, Demand, Institutions, and Firms: A Theory of Labor Market Sorting and the Wage Distribution
通过模型分析劳动力构成、劳动力需求和最低工资如何共同决定工资，发现最低工资上涨和劳动力需求冲击是1998-2012年巴西工资不平等下降的主要原因，而教育提升则通过重新分配技能工人至高工资企业来限制不平等变化。
This paper examines how workforce composition, labor demand, and minimum wage jointly determine wages through their effects on worker-task assignments, firm wage premiums, and firm-worker sorting. Using an estimated model of monopsonistic local labor markets, it finds that minimum wage hikes and labor demand shocks drove the decline in Brazilian wage inequality from 1998 to 2012. While rising educational attainment compressed skill premiums within firms, it also reallocated skilled workers to high-wage firms, limiting that shock’s effect on inequality. The analysis highlights interactions among exogenous factors, showing that concurrent supply and demand changes attenuated minimum wage impacts.
