Causal effects of alcoholism on earnings: estimates from the NLSY
使用倾向得分匹配法，基于1989和1994年NLSY数据，估计酒精中毒对年轻男性和女性收入的因果效应，发现酒精中毒导致生产力损失，且随生命周期加剧、男女有别。
Propensity score matching is used to investigate the causal relationship between alcoholism and earnings in a young cohort of males and females drawn from the 1989 and 1994 National Longitudinal Survey of Youth (NLSY) in order to investigate productivity losses attributed to alcoholism and to quantify these effects. Results suggest that there are productivity losses attributable to alcoholism; that they become more pronounced over the life cycle; and that they differ between men and women. Ways in which estimates from propensity score matching may or may not improve on instrumental variables estimates are discussed.
