Economists warned California not to raise the minimum wage to $20. They were wrong in almost every way so far, another economist says

Following California implementing a law raising its minimum wage to $20 for more than 500,000 fast-food workers in the state in 2024, Christopher Thornberg, founding partner of research firm Beacon Economics, offered a warning about the state raising its minimum wage.

“California’s well-intended push to reduce income inequality via wage floors is beginning to have a significant negative impact on some of our most vulnerable workers—our youth, particularly those from lower income households,” he wrote earlier this year.

His concerns echoed those of fast-food franchise owners, one of whom told Fortune in 2024 that higher wages would be unsustainable for smaller chains with slim margins.

But nearly two years after the law’s passage, economists are seeing very different results than what was initially feared. A working paper from University of California at Berkeley released this month found the policy increased average weekly wages for eligible workers by 11% and did not reduce employment. Prices increased modestly, about 1.5%, or the equivalent of about six cents for a $4 item.

“The results are nowhere as dire as predicted,” Michael Reich, the study author and chair of the Center on Wage and Employment Dynamics at the Berkeley institute, told Fortune.

The study compiled payroll data from Glassdoor job postings and Square and collected data on how many workers entered a fast-food establishment on a given date using Advan Research, a firm aggregating cell phone locations. It tracked changes to food price using Doordash. The analysis uses a vastly different set of data to come to the same conclusion as previous research on California’s minimum wage, which likewise found little impact of the law on employment, as well as benefits and hours.

California’s raised minimum wage for fast-food workers is part of a wider conversation the state is having around the distribution of wealth, particularly as wage growth for low-income Americans is dwarfed by those of higher-income households. California voters will decide in November if the state will impose a one-time wealth tax on residents making more than $1 billion. A survey released last month in partnership with the Los Angeles Times, found that 52% of Californians were in favor of the ballot initiative.

“Minimum wage is by far the most popular issue out there right now,” Saru Jayaraman, president of national advocacy group One Fair Wage, which is campaigning for a $30 minimum wage, told Fortune in March. “But the billionaires tax is a close second.”

Though Californians’ concerns mirror a nationwide anxiety about a growing K-shaped, or two-tiered economy, the Golden State is nearly its own economic case study. California has a $4 trillion GDP, making its economy about the same size as that of the United Kingdom’s. Home to more than 200 billionaires, the state also has the highest percentage of residents living below the poverty line in the country, 18%, in part as a result of its high cost of living.

Why economists believe panic over California’s minimum wage law was overblown

Reich said evidence from his research suggests the concerns associated with raising minimum wages are overblown. For example, the 11% increase in wages found in the study is below that approximate 25% leap in California’s $16 wage prior to the 2024 law. That’s likely because many chains were already paying their workers above the minimum. In-N-Out, for example, was offering workers a starting salary of $17.50 in 2023. California cities like San Francisco and Los Angeles already had starting wages above the state minimum prior to the law.

Moreover, labor is 30% of a restaurant’s operating costs, meaning that an 11% increase in wages would mean overall costs for a business would increase by just 3%, half of which is passed down to customers, resulting in a modest 1.5% price increase, according to Reich.

The study went as far as to say that increasing minimum wages could even increase revenue for fast-food restaurants. Higher wages are associated with increased productivity and lower turnover, Reich noted. Turnover can cost a fast-food restaurant an average of $5,864 per worker, per Cornell School of Hotel Administration data, incentivizing companies to keep their employees. The small price increase could also be beneficial to restaurants, as the tick up would likely be negligible to customers.

“When faced with small increases in fast food prices, [consumers] reduce the amount they spend by an even smaller amount,” Reich said.

Other research has contradicted Reich’s findings. A Cato Institute report from November 2025 found, using Bureau of Labor Statistics data, that the fast-food sector lost 18,000 jobs relative to the rest of the labor market. The research backs up economist Christopher Thornberg’s claims around hiked minimum wage having an outsized impact on workers who are younger and lower-income, characteristics disproportionately represented in fast food.
