From Muddling Through to the Economics of Control: Views of Applied Policy from J. N. Keynes to Abba Lerner
梳理了从J. N.凯恩斯到阿巴·勒纳关于经济理论如何指导政府政策角色的三种不同观点，适合对经济学思想史和政策理论感兴趣的读者。
This essay tells a story of changing views about economists' conceptions of what economic theory has to say about the role of government in the economy. 1 It considers three views. One is the view of J. N. Keynes and Lionel Robbins, who argue that pure economic theory has little or nothing to say about policy, but that a separate branch of economics exists that should consider such policy issues. A second view is that of Alfred Marshall and A. C. Pigou, who argue that a "realistic" theory can be used to guide judgments on policy. The third view, which is most closely related to an "economics of control" view set out by Abba Lerner, connects pure theory, policy, and the role of government in the economy in a more direct way, drawing implications about policy and the role of the state from pure theory.
