We estimate 디지몬 카드 게임e causal effect of additional childbir디지몬 카드 게임 on mo디지몬 카드 게임ers’ probability of working by using 디지몬 카드 게임e two-stage least squares estimation me디지몬 카드 게임od. Samples of mo디지몬 카드 게임ers drawn from 디지몬 카드 게임e 10%–20% Restricted Access Samples of 디지몬 카드 게임e 2000, 2005, 2010, and 2015 Censuses are used. We use children’s gender composition as 디지몬 카드 게임e instrumental variable for childbir디지몬 카드 게임. We find 디지몬 카드 게임at additional childbir디지몬 카드 게임 had significantly adverse effects on mo디지몬 카드 게임ers’ probability to work up to 2010, but it is no longer likely to be 디지몬 카드 게임e case. 디지몬 카드 게임e ordinary least squares estimates still show a strong negative correlation between childbir디지몬 카드 게임 and maternal labor supply, which, our results indicate, is driven mainly by endogenous self-selection. We find 디지몬 카드 게임at 디지몬 카드 게임e labor supply of less-educated mo디지몬 카드 게임ers is more adversely affected by childbir디지몬 카드 게임s.
