During his time as Chief Economist, he advised the Competition Commissioner on all competition cases and policy initiatives (in particular State Aid Modernization) and led the economic analysis on many large mergers (e.g. Deutsche Börse/NYSE, UPS/TNT, Univeral/EMI, H3G/Orange Austria, Western Digital/Hitachi, Outokumpu/Inoxum) and antitrust cases (e.g. Google, e-books, and the Standard Essential Patent cases), often in close cooperation with counterparts at the US agencies. Prof. Kühn spent most of his academic career as a tenured Associate Professor of Economics at the University of Michigan. His research includes theoretical, experimental, and empirical industrial organization covering a wide range of topics including durable goods, vertical integration, vertical restraints, market foreclosure, the impact of credit constraints on market behaviour, as well as collusion and the coordinated effects of mergers.
