A 2017 paper by University of Washington researchers examined the effects of Seattle's minimum wage ordinance.
The researchers found that:
A 2018 policy report from the Center on Wage and Employment Dynamics analyzed the effects of minimum wage increases, particularly on the food services industry, in six major cities.
The report says:
A paper published in the Journal of Foodservice Business Research in 2016 looked at the "effect that higher wages and health care benefits have on costs and prices in limited-service restaurants."
Researchers found, "In order to compensate for higher wages, prices would have to increase between 4 and 25% and/or product size would have to be scaled back between 12 and 70%."
The findings of the above paper are echoed by the results of a 2019 survey of 173 restaurants representing more than 4,000 locations about the impact of minimum wage increases.
The survey revealed that:
A paper published in the Southern Economic Journal in 2010 found that "state and federal minimum wage increases between 2003 and 2007 had no effect on state poverty rates."
Based on the simulated effects of "a proposed federal minimum wage increase from $7.25 to $9.50 per hour," the authors of the paper warned that "such an increase will be even more poorly targeted to the working poor than was the last federal increase from $5.15 to $7.25 per hour."
"Our results suggest that raising the federal minimum wage continues to be an inadequate way to help the working poor," the paper concluded.
A 2021 Congressional Budget Office report found that, as a result of raising the federal minimum wage to $15 an hour by 2025:
A 2020 analysis by the Employment Policies Institute found that raising the federal minimum wage to $15 by 2027 “would result in 2 million jobs lost across the United States.”
Looking at minimum wage hikes from 2006 through 2008 in Israel, a 2019 working paper found that the "the minimum wage hike reduced profits of companies," and that "profits declined more for lower-income business owners."
