Drug use, drug abuse, and labour market outcomes
研究了非法毒品使用强度与劳动力市场成功的关系，发现对年轻工人收入有正向影响，但每日使用或问题性使用会降低收入，尤其对中年男性影响显著。
This paper examines the relationship between illicit drug use and labour market success, and in doing so addresses two shortcomings of the previous literature. First, unlike many previous analyses, ours accounts for differences in intensity of use using clinically based diagnostic measures. Second, while recent studies focus only on young adults, we analyze a prime-age (30-45-year-olds) sample as well. Our results indicate that these differences are important. Similar to previous studies, we find evidence of a positive relationship between drug use and income for young workers. However, we also find some evidence of lower incomes for young workers reporting daily use of illicit drugs. For prime-age men, we find strong evidence that problematic drug use (as indicated by either a diagnosis of pathological use or dependence or by daily use) is negatively related to income. We also find a negative relationship between problematic use and employment among prime-age, but not younger, men.
