In 2017, researchers from the University of Washington studied the effects of Seattle’s minimum wage increase to $15 an hour.
They found that the average workers’ earnings dropped by $125 a month due to cuts in workers’ hours.
Overall, costs to workers outweighed the benefits by 3 to 1.
The study also estimated that there are about 5,000 fewer low-wage jobs in the city than there would have been without the law.
A UC Berkeley paper released in 2018 analyzed the effects of minimum wage increases on earnings and employment on the food services industry in six large cities.
On average, researchers found that a 10 percent increase in the minimum wage increases earnings in the food services industry between 1.3-2.5 percent.
Researchers did not detect negative significant employment effects in any of the individual cities, or when pooling them together.
A Purdue University study released in 2015 found that raising wages to $15 an hour for limited service restaurant employees would lead to an estimated 4.3 percent increase in prices at those restaurants.
The findings of the Purdue study are echoed by the results of a 2019 survey of 173 restaurants representing more than 4,000 locations about the impact of hikes in the minimum wage.
The survey revealed:
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 and that the working poor face a disproportionate share of the job losses.
"Our results suggest that raising the federal minimum wage continues to be an inadequate way to help the working poor."
The Congressional Budget Office found that raising the federal minimum wage to $15 an hour by 2025 would reduce employment by 1.4 million workers.
The number of people in poverty would be reduced by 900,000.
UC Irvine researchers studied the effects of Israel’s minimum wage hike on business owners from 2006 to 2008.
Businesses with 60-80% minimum wage staff saw their profits nearly cut in half.
Profits fell more for low-income owners than for high-income owners.
A study 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.”
