Two Sides of the Same Coin: U.S. "Residual" Inequality and the Gender Gap
研究发现，技能价格变化（认知和人际技能价格上升、运动技能价格下降）可解释美国收入不平等上升的40%和性别差距缩小的20%，基于DOT、CPS和NLSY79数据。
We show that the narrowing gender gap and the growth in earnings inequality are consistent with a simple model in which skills are heterogeneous, and the growth in skill prices has been particularly strong for skills with which women are well endowed. Empirical analysis of DOT, CPS, and NLSY79 data finds evidence to support this model. A large increase in the prices of cognitive and people skills—skills with which women are well endowed—and a decline in the price of motor skills account for up to 40 percent of the rising inequality and 20 percent of the narrowing gender gap.
