UC Santa Cruz Study Reveals the Real Impact of California's $20 Fast Food Wage: Higher Pay, Fewer Hours, and an Automation Surge

California's AB 1228 was signed into law in September 2023 with a promise: $20 per hour for fast food workers, enforced by a new Fast Food Council, would lift wages without destroying jobs. Supporters cited economic models suggesting modest, manageable tradeoffs. Opponents warned of significant job losses and price hikes. Now, more than a year after the law took effect in April 2024, the first rigorous academic study built on franchise-level interview data has landed, and the picture it paints sits uncomfortably between both camps.

UC Santa Cruz Economics Lecturer Stephen Owen spent months conducting interviews with owners and managers at more than 100 fast food franchise restaurants across the state. His findings, released in March 2026, offer something that aggregate Bureau of Labor Statistics data cannot: granular, ground-level evidence of how specific operators actually responded to the wage mandate. The results are instructive, and in some respects alarming, for the industry nationwide.

The Study's Central Findings#

The Owen study's most striking single data point comes from one McDonald's franchisee operating 18 locations in the Central Valley. After the $20 law took effect, employee hours at those restaurants dropped 11.5%. Owen calculated that reduction as equivalent to roughly 62 full-time jobs eliminated across the group, not through layoffs per se, but through hour reductions, frozen hiring, and a deliberate pullback on overtime.

That's not a rounding error. It represents a concrete, documentable response from a single operator that aggregate state-level employment figures would never isolate. The franchise owner didn't announce layoffs. The jobs didn't disappear from a BLS quarterly report. Workers simply found their paychecks lighter, even as their hourly rate climbed.

Across the broader sample, Owen found that menu prices at franchise fast food locations had risen 8 to 12 percent since September 2023, when the law was signed and operators began preparing for the April 2024 effective date. CalMatters summarized the triad of effects in a March 2026 op-ed: "higher prices, fewer jobs, more automation." Owen's data supports all three legs of that characterization.

Why This Study Is Different#

To understand why this research matters, it helps to understand what it is not. Most analyses of AB 1228's impact have relied on aggregate employment data from the BLS Quarterly Census of Employment and Wages or the California Employment Development Department. Those datasets are lagging, smoothed by sector-wide averaging, and structurally unable to separate wage-law effects from broader macroeconomic shifts, pandemic recovery patterns, or the simultaneous opening and closing of individual locations.

Owen's methodology flips that script. By interviewing franchise owners and general managers directly, he captured behavioral responses that aggregate counts miss entirely: the owner who stopped replacing departing part-timers, the GM who pulled back all overtime after June 2024, the franchisee who accelerated a kiosk rollout originally planned for 2026. These are real decisions made by real operators in response to a specific policy, and they show up in labor cost spreadsheets long before they register in state employment statistics.

This is the first academic study in California specifically to use franchise-level interview data to assess AB 1228's impact, making it an unusually direct window into operator behavior.

The Automation Response#

One of the clearest patterns Owen identified is an acceleration in technology investment. Operators interviewed for the study cited self-service kiosks, mobile ordering platforms, and reductions in scheduled overtime as the primary levers they pulled to manage the new labor cost baseline.

This tracks with broader industry investment patterns. Self-service kiosk adoption has surged across QSR since 2023, driven by a combination of post-pandemic labor tightening and the rising cost of frontline labor in high-minimum-wage states. California's $20 mandate appears to have moved the timeline for many franchisees who were already considering kiosk investment but had been weighing it against the capital cost. At $20 per hour, the math changed.

The practical effect is a structural shift in labor demand. A kiosk doesn't reduce the total number of people who can work in a restaurant, but it reduces the number required per transaction, which means a franchise owner can produce the same throughput with a smaller scheduled headcount. Multiplied across a system of hundreds or thousands of locations, the aggregate impact on available hours, and therefore on working-class California incomes, is substantial even if no single layoff announcement ever makes the news.

The Spillover Problem#

One of the more underreported consequences the study captures is the spillover effect on independent restaurants that were never subject to AB 1228 at all.

The law applied specifically to fast food chains with 60 or more locations nationally. Local independent restaurants, neighborhood taqueiras, family-owned burger stands, and regional diners were technically exempt. In practice, many raised wages anyway.

The reason is labor market competition. When McDonald's and Jack in the Box started paying $20 an hour, workers who had previously cycled between chain and independent employment had a clear reason to prefer the chains. Independent operators who wanted to retain experienced staff, particularly cooks, shift leads, and morning prep workers, found themselves competing in a labor market now anchored at $20 for entry-level chain work.

The result, per Owen's interviews, was wage increases at independent restaurants that had no obligation under the law, followed by price increases to cover the added labor cost. The policy's wage floor, intended to target large chains, effectively set a floor for the entire sector in California's labor market.

What the Numbers Tell Operators#

For multi-unit operators and franchisees outside California, Owen's study offers a useful preview of what to model if a $20 floor arrives in their state.

An 11.5% reduction in employee hours across 18 locations is not a worst-case scenario. It is a documented, mid-range response from a single franchise group trying to preserve unit economics without triggering visible layoffs. Operators who cut hours rather than headcount preserve flexibility, avoid unemployment claims, and maintain the appearance of a stable workforce, while meaningfully reducing their labor cost exposure.

Menu price increases of 8 to 12 percent over roughly 18 months are steep but have not, so far, appeared to crater traffic at California fast food locations. Consumers adjusted, particularly given that grocery prices were also elevated through much of the same period. But price elasticity has limits, and several of the chains reporting California-specific traffic softness in 2025 earnings calls cited the price environment as a contributing factor.

The kiosk and mobile ordering investment is the piece with the longest tail. Capital deployed today to reduce labor dependency at the counter or drive-thru has a multi-year payback period, but it also permanently lowers the labor content of each transaction. Operators who moved early are now running leaner than their competitors. Those who waited are now facing both elevated wages and a capital investment catch-up.

The Policy Debate Isn't Settled#

Owen's study is rigorous by academic standards, but it is not the final word. Labor economists who support the $20 floor will correctly note that one franchisee's 18 locations in the Central Valley, while detailed and instructive, is not a statewide sample. They will also note that employment in California's food service sector has not collapsed in the way some pre-law models predicted, and that the workers who are still employed are meaningfully better paid.

Both things can be true simultaneously. A policy can raise wages for those who remain employed while also reducing the total hours available to the workforce. The net welfare effect of that tradeoff is genuinely contested terrain in labor economics, and the Owen study does not try to resolve it. What it does, more valuably for practitioners, is document exactly how operators behaved in response to the law and give other operators a concrete basis for modeling their own exposure.

What Operators in Other States Should Do Now#

At least a dozen states have active legislative proposals to raise fast food or restaurant wage floors to $18 or above. For franchise operators and multi-unit owners watching those bills, the Owen study provides several directly applicable lessons.

Model hours, not just headcount. The politically visible response to a wage mandate is layoffs. The operationally practical response, as the Central Valley McDonald's franchise demonstrated, is hour reduction. Model your labor budget as total scheduled hours times blended rate, and stress-test it against a 10 to 15 percent hours reduction to see what your unit economics look like.

Front-run the technology investment. Every operator who waited until $20 took effect to begin kiosk evaluations paid a premium in rushed procurement and compressed installation timelines. If your state is moving toward a $20 floor, the time to evaluate self-service infrastructure, mobile ordering integration, and labor scheduling software is now, not the month before the law takes effect.

Price incrementally, not in a single jump. Operators who implemented 8 to 12 percent price increases gradually over 18 months maintained more customer goodwill than those who adjusted prices in large, visible steps. A consumer who sees a $0.30 increase on a value item in March and another in September is less likely to reconsider their habits than one who sees a $1.10 increase appear on a board overnight.

Watch your independent competitors. If your state implements a chain-specific wage floor, the spillover dynamic Owen documented in California means your independent competitors will face labor market pressure too, even if they are technically exempt. That creates temporary pricing paralysis for independents and, potentially, a competitive opening for chains that can absorb the cost more efficiently through scale.

Track per-transaction labor cost, not just wages. The operators who are managing best in California are those who shifted their internal benchmarking from dollars-per-hour to labor dollars per transaction or labor dollars per order. That reframe drives different investment decisions, and better ones.

California's $20 fast food wage law is now permanent policy in the largest restaurant market in the country. Owen's research gives operators outside the state their clearest look yet at what permanent looks like in practice. The headline is not that jobs disappeared overnight. The headline is that hours contracted, prices rose, capital accelerated toward automation, and the effects spread well beyond the chains the law was designed to target. That is a more complex and more useful picture than either side of the policy debate typically offers.
