The financial crisis of 2007–8 has been widely understood as a result of the financial system’s exceeding its proper place in society; the system became unbalanced, unsustainable, and deprived of a solid foundation. Even as capitalist finance seeks to reinvent itself in the wake of massive upheaval, critics continue to portray the financial system as fundamentally irrational—an unstable, destructive inventor of fictitious money. Characterizing finance in this way, however, neglects the growing connection between the worlds of high finance and consumer credit. The essays in this special issue take the financial crisis as an opportunity for much-needed conceptual innovation. Its contributors move beyond strictly moralistic criticisms of financialization to rethink core economic categories such as money, speculation, measure, value, and the wage, as well as the relationship among labor, finance, and money.
