Do Dutch dentists extract monopoly rents?
- 2018
-
Reports (other academic/artistic)abstract
- We exploit admission lotteries to estimate the payoffs to the dentistry study 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. The large payoffs cannot be attributed to longer working hours, larger human capital investments or sacrifices in family outcomes. The natural explanation is that Dutch dentists extract a monopoly rent, which we attribute to the limited supply of dentists in the Netherlands. We discuss policies to curtail this rent.

The Returns to Medical School: Evidence from Admission Lotteries
- 2016
-
In: American Economic Journal: Applied Economics. - : American Economic Association. - 1945-7782 .- 1945-7790. ; 8:2, s. 225-254

Journal article (peer-reviewed)abstract
- We exploit admission lotteries to estimate the returns to medical school in the Netherlands. Using data from up to 22 years after the lottery, we find that in every single year after graduation doctors earn at least 20 percent more than people who end up in their next-best occupation. Twenty-two years after the lottery the earnings difference is almost 50 percent. Only a small fraction of this difference can be attributed to differences in working hours and human capital investments. The returns do not vary with gender or ability, and shift the entire earnings distribution.

Expanding schooling opportunities for 4-year-olds
- 2010
-
In: Economics of Education Review. - : Elsevier BV. - 0272-7757 .- 1873-7382. ; 29:3, s. 319-328
-
Journal article (peer-reviewed)abstract
- We use a novel quasi-experimental strategy to estimate the effect of expanding early schooling enrollment possibilities on early achievement. It exploits two features of the school system in The Netherlands. The first is rolling admissions; children are allowed to start school immediately after their 4th birthday instead of at the beginning of the school year. The second is that children having their birthday before, during and after the summer holiday are placed in the same class. These features generate sufficient exogenous variation in children’s enrollment opportunities to identify its effects on test scores. Making available one additional month of time in school increases language scores of disadvantaged pupils by 6 percent of a standard deviation and their math scores by 5 percent of a standard deviation. For non-disadvantaged pupils we find no effect.

Information Frictions, Internet, and the Relationship between Distance and Trader
- 2022
-
In: American Economic Journal. - : American Economic Association. - 1945-7782 .- 1945-7790. ; 14:1, s. 133-163
-
Journal article (peer-reviewed)abstract
- We examine how the adoption of information communication technology affects bilateral trade. The context is a public program in Norway that rolled out broadband access points leading to plausibly exogenous variation in the availability and adoption of broadband by firms. We find that broadband makes trade patterns more sensitive to distance and economic size. These results are consistent with a model of trade with variable elasticity of demand. The model predicts that adoption of a technology that lowers information frictions enlarges the choice set of exporters and importers. This makes demand more elastic with respect to trade costs and thus distance.
