California's $20 fast-food wage made workers stay, not leave
What happened
California raised the minimum wage for large fast-food chains to $20 per hour. This made wages go up, but workers also stopped quitting their jobs as much, and few jobs were lost.
Why it matters
For years, economists debated if big minimum wage hikes would kill jobs. This paper shows that in California's fast-food industry, the main effect was workers staying put. It suggests that higher wages can reduce turnover costs for businesses, offsetting some of the wage increase.
The signal
Watch if other states or cities adopt similar large minimum wage increases, and if their labor markets show similar low job losses and reduced turnover.
