Do Dutch dentists extract monopoly rents?

We exploit lottery-determined admission to dental school to estimate the payoffs to the study of dentistry in the Netherlands. Using data from up to 22 years after the lottery, we find that in most years after graduation dentists earn around 50,000 Euros more than they would earn in their next-best profession. The payoff is larger for men than for women but does not vary with high school GPA.

Among the applicants for medical school, people who attended medical school have on average 1.5 more years of completed education than people who did not.
