Most academic economics rely on concepts laid down at the beginning of the twentieth century by the British economist Alfred Marshall, who said that “nature does not make leaps.” Yet we economists find ourselves increasingly disturbed by the apparent inadequacy of the neo-Marshallian toolkit that we have built to explain our world.
大多数学院派经济学理论都建立在20世纪初英国经济学家阿尔弗雷德·马歇尔提出的概念上。他曾说过，“自然不允许跃进”。然而我们经济学家却发现自己越来越被我们构建出来解释世界的新马歇尔主义的明显不足所困扰。
