Why do married men earn more: productivity or marriage selection?
利用1999年当前人口调查数据，研究发现已婚男性的工资溢价并非源于其更高的潜在收入能力，而是由家庭内部分工所致，质疑了高能力男性选择结婚导致溢价的观点。
Using data from the Current Population Survey March Supplement 1999, this study examines why married men earn more than men who have never married. We find that the marriage wage premium cannot be attributed to the unobservable higher earnings capability of married men. Instead, wage gains from marriage are explained by the degree of specialization within the household. Our findings cast doubt on the argument that the selection of high-ability men into marriage is the cause of the marriage wage premium.
