The Effects of Major Retailers Raising Their Minimum Wages

Minimum wage announcements by national firms have striking spillovers to other firms. Many employers responded to Amazon’s $15 minimum wage by matching it.
Between 2014 and 2019, five major national retailers — Amazon, Walmart, Target, CVS, and Costco — implemented company-wide minimum wages. Ellora Derenoncourt, Clemens Noelke, David Weil, and Bledi Taska investigate the impacts of these policies on low-wage workers who are not employed by these firms in Spillover Effects from Voluntary Employer Minimum Wages (NBER Working Paper 29425). They first illustrate their findings using Amazon’s $15 minimum wage, which was announced in October 2018 and took effect that November 1. They then show these patterns generalize to the other large retailer minimum wages.
