下面是一个SAT写作经典例子，是关于诺贝尔经济学奖获得者John Nash的生平的介绍。这篇SAT写作例子之所以经典，是因为这个人物的生平非常的跌宕起伏，遭遇了很多的挫折，但是又取得了很多的成绩，非常具有代表性。下面是详细内容。 Key words: economist illness Nobel price winner John Nash When the young Nash had applied to graduate school at Princeton in 1948, his old Carnegie Tech professor, R.J. Duffin, wrote only one line on his letter of recommendation: This man is a genius. It was at Princeton that Nash encountered the theory of games, then recently launched by John von Neumann and Oskar Morgenstern. However, they had only managed to solve non-cooperative games in the case of pure rivalries . The young Nash turned to rivalries with mutual gain. His trick was the use of best-response functions and a recent theorem that had just emerged - Kakutanis fixed point-theorem. His main result, the Nash Equilibrium, was published in 1950 in the Proceedings of the National Academy of Sciences. He followed this up with a paper which introduced yet another solution concept - this time for two-person cooperative games - the Nash Bargaining Solution in 1950. A 1951 paper attached his name to yet another side of economics - this time, the Nash Programme, reflecting his methodological call for the reduction of all cooperative games into a non-cooperative framework. |
