The Incredible Shrinking Elasticities
利用三月当前人口调查数据，发现已婚女性劳动供给弹性在过去25年大幅下降，小时工资弹性下降60%，参与工资弹性下降95%，且人口特征变化只能解释一小部分，表明不同出生队列的工作偏好发生了改变。
Abstract This paper demonstrates the extent to which married women's labor supply elasticities have changed over the past quarter century. Estimates from March Current Population Survey data suggest that these elasticities have decreased substantially, by 60 percent for the hours wage elasticity (from 0.36 to 0.14), 70 percent for the hours income elasticity (from -0.053 to –0.015), 95 percent for the participation wage elasticity (from 0.66 to 0.03), and 60 percent for the participation income elasticity (from –0.13 to –0.05). Changing demographic characteristics explain little of the drop in these elasticities, suggesting that preferences toward work have changed across birth cohorts.
