The Minimum Wage Study is a research effort dedicated to providing rigorous analysis of the impact of minimum wage ordinances in metropolitan regions and states. We seek to provide insights that will be useful for policymakers and scholars. As more states and localities move forward with plans to raise the minimum wage, this research will infuse the debate with data on the effects on workers, households, employers, and the local economy. We focus our analysis on the impacts of recently passed ordinances in Seattle and Chicago, as well as other areas.

Seattle’s Minimum Wage
In January 2014, Mayor Ed Murray formed an Income Inequality Advisory Committee to address the growing public call for a meaningful increase in the compensation for Seattle workers. This committee included representatives from Seattle City Council, local businesses, unions, and the Chamber of Commerce. After the committee reached an agreement on a recommendation, it was proposed as a plan by the Mayor, and then passed as legislation by the Seattle City Council. The minimum wage ordinance (Ordinance 124490), which when approved was the highest minimum wage in the country, provides for an increase in the minimum wage in the City of Seattle to $15 an hour, phased on over time. The rate at which it increases depends on the size of the company, and whether or not they pay toward their employee’s medical benefits plan.
In December 2014, after issuing a public request for proposals, the City of Seattle contracted with our team to conduct this evaluation.
