The Effects of Licensing on the Wages of Radiologic Technologists

  • Edward J. Timmons

We analyze the effect that state licensing of radiologic technologists (RTs) has had upon RT wages with a unique dataset that allows us to control for place of work and job specialization. Using OLS and several measures of licensing, we find evidence that RTs working in states with licensing statutes earn as much as 3.3% more than RTs working in states without licensing. When we control for endogeneity using instrumental variables (IV) estimation, our estimate of the licensing premium doubles (6.9%). Our results provide further support for existing theories of the effects of occupational licensing on the wages of practitioners.
