In Honor of Paul Krugman: Winner of the John Bates Clark Medal
介绍1991年约翰·贝茨·克拉克奖得主保罗·克鲁格曼的研究贡献，涵盖产品多样性、垄断竞争贸易、寡头垄断与战略贸易政策、贸易与汇率动态等主题，并讨论其著作《期望减退的时代》。
Paul Krugman is the winner of the 1991 John Bates Clark Medal, given every two years to “that American economist under forty who is adjudged to have made a significant contribution to economic thought and knowledge.” I shall attempt to convey a flavor of Krugman's research contributions, grouped into some major themes: product diversity and monopolistically competitive trade; oligopoly and strategic trade policy; the dynamics of trade and exchange rates; and much more. Finally I discuss his brilliant popular book, The Age of Diminished Expectations (1991).
