Employer Wage Subsidy Caps and Part-Time Work
利用美国人口普查数据，研究发现当工资补贴设有上限时，企业会增加兼职员工的使用，尤其是在补贴上限可能起作用的地区，同时也会转向雇佣技能较低的工人。
Using tract-level US Census data and triple-difference estimators, the authors test whether firms increase their use of part-time workers when faced with capped wage subsidies. By limiting the maximum subsidy per worker, such subsidies create incentives for firms to increase the share of their payroll that is eligible for the subsidy by increasing use of part-time or low-wage workers. Results suggest that firms located in federal Empowerment Zones in the United States responded to the program’s capped wage subsidies by expanding their use of part-time workers, particularly in locations where the subsidy cap is likely to bind. Results also show a shift toward hiring lower-skill workers.
