Abstract:
|
In the United States, occupational licensing varies widely from state to state, and one-third of the workforce is licensed. Research has consistently found that occupational licensing creates market power and monopoly effects, but conventional wisdom and courts argue that occupational licensing protects the public health and safety. Current research on licensing for professional occupations suggests that licensing may change the distribution of quality, or may change quality differentially across income groups. However, there is less research on the impact of licensing for quality in service-based occupations, which represent the bulk of the growth in licensing. I employ a unique dataset of individual Yelp business ratings to estimate the relationship between licensing and quality for four service-based occupations. I first test whether licensing impacts competition for these occupations using a negative binominal model and find a negative relationship between more licensing and the number of firms. I then design a difference-in-differences model with state fixed effects, using business location near state borders as a treatment group and state requirements for licensing as the treatment. Yelp ratings are used as the measure of service quality. I find that having any licensing for an occupation lowers quality within a state. I estimate the effect of licensing on quality for five different types of licensing and find that licensing exams significantly lower quality. I also find evidence for diminishing returns to quality from education and training and licensing exams. The results are robust to several specification tests.
