My current research focuses on three broad themes: (1) occupations and wage inequality, (2) school-to-work linkages, and (3) cumulative advantage in science
Occupations and wage inequality
In 2015 I received a Veni grant to study occupations and wage inequality in Europe. Several studies show that the growth in wage inequality in the United States and the United Kingdom took place between occupations, but we do not know yet to what extent this is also the case for Europe. Furthermore, we have only very little knowledge on why some occupations increasingly pay more than others. In my Veni-project I will work on these questions. A brief (non-scientific) outline of my project can be found here.
I have already worked on the relation between occupations and wage inequality. In existing work I  have studied how occupational closure affects mean occupational wages in Germany and the UK (with Kim Weeden). A more recent project focuses on Norway, and studies how between-occupation wage inequality is explained by institutional barriers to access occupations (with Ida Drange, for the project website click here). I furthermore work on occupational polarization in the Netherlands, and study how occupational job tasks affect wage inequality in the UK (with Mark Williams).
School-to-work linkages
Second, I study school-to-work linkages in a comparative perspective. With colleagues (Tom DiPrete, Christina Ciocca, and Herman van de Werfhorst), I developed a new method to analyze school-to-work linkages. By using segregation techniques, we are able to provide a detailed description of how specific educational degrees connect to occupations, and how this is different across three institutionally diverse countries (France, Germany, and the United States). One paper investigates how the “linkage strength” of a specific educational degree affects the returns to this degree. Another paper focuses on the historical changes in linkage strength in France and Germany (with Benjamin Elbers and Tom DiPrete). A final project studies how the effects of linkage strength vary across the life course (with Andrea Forster).
Cumulative advantage in science
Together with Mathijs de Vaan and Arnout van de Rijt, I analyze the cumulative advantage in obtaining science grant acquisition in the Netherlands. We analyze the Netherlands’ Scientific Organization’s (NWO) applications data for 2000-2015, to see to what extent winners of a starting grant (Veni) are more likely to win a follow-up grant (Vidi), and why this is the case.
