Michel Aglietta’s path-breaking book is the first attempt at a rigorous historical theory of the whole development of US capitalism, from the Civil War to the Carter presidency. A major document of the “Regulation School” of heterodox economics, it was received as the boldest book in its field since the classic studies of Paul Baran, Paul Sweezy and Harry Braverman. This edition includes a substantial postface by Aglietta, which situates regulation theory in the context of twenty-first-century capitalism.
