A Nobel Prize for Game Theorists: The Contributions of Harsanyi, Nash and Selten
庆祝哈萨尼、纳什和泽尔腾对经济学的贡献，重点追溯其工作对经济分析的影响，指出他们分别代表了博弈论中均衡、不对称信息和可信性这三个核心思想。
The purpose of this essay is to celebrate the contributions of John C. Harsanyi, John F. Nash, and Reinhard Selten to economics. The emphasis is on tracing the influence of their work on economic analysis rather than giving a detailed account of each of their contributions. The three researchers are identified with the three most important ideas in game theory: equilibrium, asymmetric information, and credibility. These three ideas have dominated not only theoretical research but also numerous other fields within economics since the 1950s.
