About Claes Ek

I am Senior Lecturer at the Department of Economics at the University of Gothenburg. I obtained my PhD from Lund University in September 2016. My research interests are in in environmental and behavioral economics, applied econometrics and public economics.

My main current projects include field experiments on household waste and recycling behavior. One recent project successfully applies norm-based feedback nudges (similar to the well-known Home Energy Reports) in the waste domain. Another ongoing project relates to power calculations for experiments with panel data, including for cluster-randomized field experiments.

I've also done research on the issue of within-individual spillovers across prosocial activities, for instance in response to policy meant to encourage one particular such activity. For example, if local government incentivizes recycling, will people become more or less inclined to buy organic food or bike to work?
