The Effect of Illicit Drug Use on the Wages of Young Adults
研究可卡因和大麻使用对年轻成年人工资的影响，使用两阶段最小二乘法处理内生性，发现药物使用与更高工资相关，且该关系不随年龄减弱。
This article examines the effects of cocaine and marijuana use on the wages of young adults. The endogeneity of drug use in a wage equation is considered and a two-stage least squares procedure is implemented. The results suggest that increased use of marijuana or cocaine is associated with higher wages. The positive relationship between drug use and the wage does not diminish with age. The author also investigates whether systematic differences in the return to measures of human capital investments can explain the positive relationship between drug use and wages.
