Two Sides of the Same Coin
研究发现，技能价格变化——认知和人际技能价格上涨、运动技能价格下降——解释了高达40%的收入不平等加剧和20%的性别差距缩小，基于DOT、CPS和NLSY79数据的实证分析支持这一模型。
Abstract 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.
