Are the self-employed more stressed? New evidence on an old question
利用端粒长度这一生物指标，研究了自雇与心理压力的关系，发现自雇者压力更大，且从业时间越长压力越难缓解。
Are the self-employed more stressed than the employed? Current research on entrepreneur stress are mixed. We utilize the age-adjusted telomere length to test the influence of human capital on self-employment and stress. Data from 3,580 adults in the 1999–2000 and 2001–2002 National Health and Nutrition Examination Survey were fitted to a theoretical model. Our findings support previous studies showing a positive relationship between self-employment and psychological stress. Moreover, we find that job tenure strengthens this relationship, implying that the self-employed who experience mental stress may find it challenging to recover the longer they have been self-employed.
