Female Earnings Inequality: The Changing Role of Family Characteristics and Its Effect on the Extensive and Intensive Margins
利用PSID三个队列的女性数据，发现1960年代末至1990年代中期女性年收入不平等大幅下降，主要源于广延边际的贡献下降；模型显示超过80%的下降可归因于家庭因素（子女、伴侣及其收入）与收入决定边际之间关联的减弱。
Using data for three cohorts of women in the PSID, we show that annual earnings inequality fell sharply between the late 1960s and the mid-1990s, with a large decline in the component attributable to the extensive margin. We then fit earnings-generating models that incorporate both intensive- and extensive-margin dynamics to data for the three cohorts. Our models suggest that more than 80% of the decline in female earnings inequality can be attributed to a weakening of the link between family-based factors (i.e., children and the presence and incomes of partners) and the intensive and extensive margins of earnings determination.
