Is There a Causal Effect of Working Part‐Time on Current and Future Wages?
使用随机效应模型和动态多项probit模型，研究兼职工作对当前和未来工资的因果效应，发现少量兼职会大幅降低当前工资，而两种兼职都会带来长期负面工资影响。
Abstract In this paper, I study the causal effects of part‐time work on current and future wages. To estimate these effects, I use a random effects model with a wage equation capturing the employment history and a dynamic multinomial probit component for the choice of employment status. Exclusion restrictions from the institutional context are exploited to support identification. The results suggest that working part‐time with few hours has a large causal effect on current wages, but more extensive part‐time work does not reduce current wages. However, both types of part‐time work lead to negative long‐term wage effects.
