PRICE FLOORS AND EMPLOYER PREFERENCES: EVIDENCE FROM A MINIMUM WAGE EXPERIMENT
ABSTRACT
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. The reduction in hiring was fairly small, even at the highest minimum wage imposed. In contrast, minimum wages substantially reduced hours-worked, across cells. Firms facing a higher minimum wage shifted to hiring more productive workers. This labor-labor substitution margin of adjustment would presumably be less effective in equilibrium, if all firms sought out 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 and a shift to using non-wage based contracts.
