In this paper, I analyze the effect that the introduction of barber licensing requirements in Alabama has had on the market for barbering services in the state. By comparing data on beauty shops and barber shops in Alabama, barber shops in Alabama and bordering states, and barber shops in Alabama counties bordering Georgia and Florida, I consistently find evidence suggesting that the introduction of barber licensing in Alabama is associated with a reduction in barber shop growth in the state. I also generally find evidence that barber shop receipts increases in Alabama after the adoption of barber licensing. These results are supportive of the economic theory that licensing primarily has negative supply-side effects, restricting competition in the marketplace and thus harming consumers. As policymakers reconsider the costs and benefits of occupational licensing, this case study of barbering services in Alabama should serve as an example of the possible negative consequences of such laws.
