In January 2016, Seattle’s minimum wage jumped from $11 an hour to $13 for large employers, the second big increase in less than a year. New research released Monday by a team of economists at the University of Washington suggests the wage hike may have come at a significant cost: The increase led to steep declines in employment for low-wage workers, and a drop in hours for those who kept their jobs. Crucially, the negative impact of lost jobs and hours more than offset the benefits of higher wages — on average, low-wage workers earned $125 per month less because of the higher wage, a small but significant decline.
The paper’s findings are preliminary and have not yet been subjected to peer review. And the authors stressed that even if their results hold up, their research leaves important questions unanswered, particularly about how the minimum wage has affected individual workers and businesses. The paper does not, for example, address whether displaced workers might have found jobs in other cities or with companies such as Uber that are not included in their data.
