This sequel to Marx and Non-Equilibrium Economics introduces the key advances in modern value theory. Leading authors with contrasting theoretical viewpoints debate equilibrium and non-equilibrium approaches, abstract labour and money, and provide an invaluable introduction to the rapidly growing body of new work in these fields. The authors cover cutting-edge topics in value theory including gender and money, crisis theory, the impact of technology, skilled and complex labour, and the effect of international transfers of value. All of the papers in The New Value Controversy and the Foundations of Economics concentrate on new research. The mathematical content is minimal, allowing both active researchers and new students to introduce themselves to the burgeoning critical reappraisal of the foundations of Twentieth Century economic thinking.
