Rising U.S. Earnings Inequality and Family Labor Supply: The Covariance Structure of Intrafamily Earnings
研究1980年代初工资不平等加剧时期，劳动供给对个人和家庭收入不平等的影响，发现丈夫劳动供给弹性为0.05，妻子为0.40，劳动供给解释了家庭不平等上升的20%以上和女性不平等上升的50%。
This paper studies the labor supply contributions to individual and family earnings inequality during the period of rising wage inequality in the early 1980's. Working couples have positively correlated labor market outcomes, which are almost entirely attributable to permanent factors. An intertemporal family labor supply model with this feature is used to estimate labor supply elasticities for husbands of 0.05, and wives of 0.40. This implies that labor supply explains little of the rising annual earnings inequality for married men, but over 20 percent of the rise in family inequality and 50 percent of the modest rise in female inequality.
