Productivity Differences and the Marriage Wage Premium for White Males
利用美国青年纵向调查数据，发现已婚与未婚男性之间的劳动生产率差异不太可能是婚姻工资溢价的原因。
Attempts to account for the positive, and often large, wage premium paid to married men based on their greater productivity have been inconclusive. Using data from the National Longitudinal Survey of Youth, this paper provides new evidence that labor productivity differences between married and never-married men are unlikely to be the cause of the marriage premium.
