Is there a wage bonus from drinking? Unobserved heterogeneity examined
While the result that drinkers earn more than abstainers has been remarkably persistent, only one paper in the literature on drinking and earnings has been written where individual fixed effects are included. This study improves the current literature by utilizing a much longer panel and focuses on the low end of drinking while controlling for unobserved heterogeneity with the inclusion of individual specific effects. It is found that while OLS specifications yield a positive significant coefficient on current drinking, even when a rich set of covariates is controlled for, including individual fixed effects renders the coefficient statistically insignificant.
