Teaching

I stopped teaching at Aarhus University at the end of 2023 after almost twenty years commuting from Copenhagen. Here are the study materials for the last courses I was teaching at AU.

• Applied Public Policy (Click here for information about the course)

  This class was aimed at students in their final year of studies. The goal was to help students figure out how to come up with a thesis project and do policy oriented research.

• Danish Society: Culture, Institutions and Markets (Click here for my lecture slides)

  This class was offered to international students at Aarhus University. The goal was to expose them to university level ideas, and to help them reflect on culture, institutions and markets in Denmark, and draw comparisons across time and place.

Both classes were discussion friendly courses, and my teaching evaluations were in the 4 out of 5 range. The evaluations were much better than what I would get teaching pure economic theory in the mathematics department, and this helped me see that students needed a lot more engagement and context than what I tended to offer in the past. Programs like DIS in Copenhagen offer a great way to realize that ideal.

Rowing club

Clubs and associations are a vital part of Danish society. Anyone living or working in Denmark should consider joining one — they’re a great way to meet people and become part of the local community. Denmark has a long tradition of participating in sports and shared activities through foreninger (associations). If you are living in Copenhagen, I can highly recommend that you look into my rowing club!

Publications

My research is generally about how markets work and how people and policies interact. Some of my research papers have a macroeconomic flavor, while other research papers are more microeconomic in orientation. Others simply try to establish a causal connection between a treatment A and an outcome B using an experimental design to establish a control group. The first three papers on the following list of publications give examples of all these approaches related to understanding childcare.
