Did a higher fast food minimum wage reduce fast food employment?
Core argument: Employment in California's fast food sector fell 2.7% relative to the fast food sector elsewhere in the United States from September 2023 through September 2024, in unadjusted Quarterly Census of Employment and Wages data.
We analyze the effect of California's $20 fast food minimum wage [up from $16], which was enacted in September 2023 and went into effect in April 2024, on employment in the fast food sector. We document that AB 1228 increased wages substantially, with a roughly 8% increase in California’s fast food sector relative to the fast food sector elsewhere in the country. In unadjusted data from the Quarterly Census of Employment and Wages, we find that employment in California's fast food sector declined by 2.7% relative to employment in the fast food sector elsewhere in the United States from September 2023 through September 2024. In Figures 1b, 1c, and 1d, for which each series has been indexed relative to September 2023, the magnitude of the relative decline through late 2024 is readily observed from the graphs as being on the order of 2 to 4%. Indexing, detrending, and seasonally adjusting the data make the series more visually comparable but do not substantively alter the relative movements that underlie our regression estimates. Our median estimate translates into a loss of 18,000 jobs in California's fast food sector relative to the counterfactual.
