The study of American political economy requires focus on a very different set of actors than does the conventional study of American politics as practiced by contemporary scholars. In particular, the core questions surrounding the American political economy call for a deep understanding of the preferences, power, and tactics of organized actors – and the ways that those organized actors both influence, and are influenced by, economic and political institutions. And within the universe of US organized interests, producer and class interests are especially relevant, encompassing labor, business, and increasingly, wealthy Americans that are collectively constitutive of the political economy. Such a political economy perspective contrasts with other approaches that either do not center economic interests or treat such interests as relatively interchangeable with one another.
