Jean Tirole received the 2014 Nobel Memorial Prize in Economic Sciences for his analysis of market power and regulation.
The committee recognized Tirole’s research on how governments should regulate powerful firms, including monopolies and firms in concentrated industries. His models examined problems such as price setting, barriers to entry, information asymmetry, and incentives for investment.
Tirole showed that effective regulation cannot rely on a single universal rule. The best policy depends on the industry’s structure, the information available to regulators, and the strategic behavior of firms. His work influenced regulation of telecommunications, banking, and other network or infrastructure industries.
Tirole was born in Troyes, France, in 1953. He worked at the Toulouse School of Economics and was also affiliated with the Institute for Advanced Study in Toulouse. His 2017 textbook, Economics for the Common Good, addressed economic policy for a general audience.
