Abstract
Frank Hahn was both a Keynesian economist, active in policy debates, and an economic theorist. Placing his work in the context of attempts to make theoretical sense of Keynesian economics, this article explores the way Hahn used abstract general equilibrium theory to draw conclusions relevant to policy in an ‘imperfect’ world that does not conform to the assumptions made in the theory. Hahn’s rigorous approach to theorizing as the route to understanding is assessed in relation to the different approaches of Robert Lucas, Milton Friedman, Paul Samuelson and Axel Leijonhufvud.

不完美世界中的经济理论:弗兰克·哈恩(Frank Hahn),一般均衡和凯恩斯主义经济学

摘要
弗兰克·哈恩(Frank Hahn)既是凯恩斯主义的经济学家,活跃于政策辩论,还是一位经济理论家。本文将他的工作放在试图使凯恩斯主义经济学具有理论意义的背景下,探索哈恩使用抽象的一般均衡理论得出与“不完美”世界中与政策有关的结论不符的假设的方式,该结论不符合该理论中的假设。 。相对于罗伯特·卢卡斯(Robert Lucas),米尔顿·弗里德曼(Milton Friedman),保罗·萨缪尔森(Paul Samuelson)和阿克塞尔·莱昂洪福夫(Axel Leijonhufvud)的不同方法,对哈恩(Hahn)严格的理论化方法进行了评估。
