I am a Professor of Economics at BI Norwegian Business School. I hold a Ph.D in Economics from the London School of Economics, where I also was employed as Lecturer. In the academic year 2004-2005 I was visiting professor at Northwestern University. From 2011-2016 I was non-voting member of the board of Norges Bank, which is also the board of the Government pension fund (NBIM). My area of research is mostly within economic theory, with applications mainly to labor economics and industrial organization. I have also done empirical works within labor economics. I have published in leading journals like the Journal of Political Economy, the Review of Economic Studies, and American Economic Review. I am Research Fellow at the CEPR (Center for Economic Policy Research), and Fellow of the European Economic Association. In 2011 I was Scientific Chairman for the EEA annual congress in Oslo. I am also associated editor (previously editor) of the Scandinavian Journal of Economics and partner in the consulting firm Oeconomica. I have undertaken projects within several different industries, including telecommunication, agriculture, energy and housing. I have testified in court as an expert witness on a number of occasions, for the Supreme court in 2014.
