The Impact of Psychiatric Disorders on Labor Market Outcomes
利用美国全国共病调查数据，通过工具变量法纠正内生性，发现精神疾病显著降低男女就业率，并减少男性工作小时及男女收入。
Data on 2225 men and 2401 women from the National Comorbidity Survey were used to examine the impact of psychiatric disorders on employment and conditional work hours and income. Two-stage instrumental variables methods were used to correct for the potential endogeneity of psychiatric disorders. The instruments used (the psychiatric disorder history of the respondent and respondent's parents) passed tests of the overidentifying restrictions. Psychiatric disorders significantly reduced employment among both men and women. Evidence was also found of small reductions in the conditional work hours of men and a substantial drop in the conditional earnings of men and women, although these findings were somewhat more sensitive to the estimation methods and specification of the model.
