"In the late nineteenth century, influenced by the drive to create a science of society modeled after developments in the hard sciences, William Jevons and Alfred Marshall, among others, established the neoclassical paradigm that continues to provide a model for mainstream economics. Choosing to concentrate on describing, preferably through a set of mathematical equations, the outcomes of different combinations of productive factors (land, labor, and capital), this school of thought eliminated most of the political from political economy.

In the twentieth century, the neoclassical view became what Kuhn (1970) calls “normal science,” or textbook economics. Not unlike the way Newtonian mechanics came to mean physics, the neoclassical approach came to mean economics. But the process of normalizing economics was one of continuous intellectual and political ferment that itself merits a volume on the political economy of economics (Foley, 2006). The so-called Austrian and Cambridge wings of the mainstream neoclassical school debated the centrality of markets and the role of the state. Institutional, Marxian, and corporatist approaches leveled more fundamental criticisms at the paradigm’s assumptions, concepts, conclusions, and engagement (or lack of engagement) with political and social life."
