The Evolution of Technological Substitution in Low-Wage Labor Markets
利用最低工资上调评估低工资就业受技术替代的影响，发现2008-2009金融危机后自动化加速取代更多低工资常规岗位，而人际岗位增长不足以完全抵消损失，非亚裔有色人种就业损失最大。
Abstract This paper uses minimum wage hikes to evaluate the susceptibility of low-wage employment to technological substitution. We find that automation is accelerating and supplanting a broader set of low-wage routine jobs since the 2008–2009 financial crisis. Simultaneously, low-wage interpersonal jobs are increasing and offsetting routine job loss. However, interpersonal job growth does not appear to be enough, as it was prior to the financial crisis, to fully offset the negative effects of automation on low-wage routine jobs. Employment losses are most evident among non-Asian people of color who experience outsized losses at routine jobs and smaller gains at interpersonal jobs.
