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.


David Weil is Dean and Professor at Brandeis University’s Heller School of Social Policy and Management. He served as US Wage and Hour Administrator at the Department of Labor during the last three years of the Obama administration. He is a leading international expert on workplace and labor market policy and was the Peter and Deborah Wexler Professor of Management at Boston University’s Questrom School of Business before coming to Brandeis. The materials on this site arise from analysis contained in The Fissured Workplace and a growing body of research regarding the fundamental restructuring of employment and its impacts on workers and businesses. It also discusses approaches to dealing with the fissured workplace developed during the Obama administration as well as new ideas and efforts being discussed and undertaken today.
