Wage Shocks and the Technological Substitution of Low‐wage Jobs
研究了最低工资上涨如何通过技术替代影响低工资就业，发现认知常规性岗位就业下降，而其他低工资岗位增长，导致受影响的工人相对工资受损。
We extend the task‐based empirical framework used in the job polarisation literature to analyse the susceptibility of low‐wage employment to technological substitution. We find that increases in the cost of low‐wage labour, via minimum wage hikes, lead to relative employment declines at cognitively routine occupations but not manually‐routine or non‐routine low‐wage occupations. This suggests that low‐wage routine cognitive tasks are susceptible to technological substitution. While the short‐run employment consequence of this reshuffling on individual workers appears to be economically small, due to concurrent employment growth in other low‐wage jobs, workers previously employed in cognitively routine jobs experience relative wage losses.
