San Francisco's minimum wage will increase to $14 an hour this Saturday.
The jump from $13 was part of an increase approved by voters in 2014. In San Francisco, 128,00 workers starting July 1 will get a pay raise on average about $700 more for the year.
But does it really make a difference? Labor researchers have been looking into the impact of raising the minimum wage, particularly in the restaurant business.
Ken Jacobs, chairman for UC Berkeley's Center for Labor Research and Education, said there is no measurable effect on jobs to date.
Jacobs said the primary reason is that workers are not just labor, they are also consumers. Or in the case of restaurants, workers are also customers -- if they make more they spend more.
"And what the research has shown is those two things really balance things out," Jacobs said.
San Jose is also raising the minimum wage on July 1 from $10.50 to $12 an hour.
