This note uses data from the National Longitudinal Study of Adolescent Health to examine the relationship between body weight and wages. Ordinary least squares (OLS) and individual fixed effects estimates provide evidence that overweight and obese white women are paid substantially less per hour than their slimmer counterparts. Two-stage least squares (2SLS) estimation confirms this relationship, suggesting that it is not driven by time-variant unobservables.
本文使用来自全国青少年健康纵向研究的数据，考察了体重与工资之间的关系。普通最小二乘法（OLS）和个体固定效应估计提供的证据表明，超重和肥胖的白人女性每小时的工资明显低于身材较苗条的女性。两阶段最小二乘法（2SLS）估计证实了这种关系，表明这不是由时变不可观测因素驱动的。
