Price Floors and Employer Preferences: Evidence from a Minimum Wage Experiment - American Economic Review 2025 - 117-146

Firms posting job openings in an online labor market were randomly assigned minimum hourly wages. When facing a minimum wage, fewer firms hired, but those they did hire paid higher wages. Hours-worked fell substantially. Treated firms shifted to hiring more productive workers. Using the platform's imposition of a market-wide minimum wage after the experiment, I find that many of the experimental results also hold in equilibrium, including the substitution towards more productive workers. However, there was also a large reduction in the number of jobs posted for which the minimum wage would likely bind.
