Tirole

Contributions to economics

Tirole's textbook, The Theory of Industrial Organization, synthesised modern models of oligopolistic competition, analysing various cases where industries consist of a small number of firms with significant market power. He and Oliver Hart published a paper showing the conditions in which a vertical merger can result in foreclosure. Rochet and Tirole analysed the implications of 2-sided markets for competition policy. Fudenberg and Tirole also created a taxonomy of strategic effects in oligopolistic competition models.
