Paul Heidhues

Paul Heidhues worked on topics in competition economics such as input-market bargaining power, merger control, collusion, and the functioning of markets when consumers are partly driven by psychological factors that the classical consumer model abstracts from. Much of his ongoing research focuses on the implications of consumer mistakes for imperfect competition and consumer-protection regulation. Paul is a member of DG Competition’s European Advisory Group on Competition Policy, of the UK‘s Competition and Markets Authority’s Academic Panel, and of the Bundeskartellamt’s Arbeitskreis Kartellrecht. His work appeared in leading academic journals such as the American Economic Review, Econometrica, the Quarterly Journal of Economics, and the Review of Economic Studies.
