Using survey data from 2015 to 2018, this article analyses the occupational licensing wage premium in the United States. The estimates show a robust 4–6 per cent wage differential for licensed workers. This premium is robust to careful control for location/local labour market effects and occupation effects. The premium is also positive for the majority of individual occupations and groups of occupations estimated. Similar results are found using additional techniques, including a matching estimator and an analysis of border metropolitan statistical areas.
