Economics has long modeled its theories on bakers and butchers rather than husbands, wives, lovers, and prostitutes. This book argues that exchanges involving sex and intimacy, far from being external or exceptional in relation to the workings of the economy, come closest to the reality of capitalist money. Undertaking an inquiry into the sexual economy of capitalism, Noam Yuran analyzes the erotic and gendered meanings that suffuse basic economic concepts, from money to the commodity. It is not entirely true, Yuran shows, that in capitalism everything has its price. In fact, the category of things money cannot buy, including love, forms a central axis around which capitalist economic life is organized. It is inscribed on goods and economic motivations and conduct, and distinguishes capitalism from precapitalist economies in which marriage was an exchange and wives were owned. In conversation with psychoanalysis, feminist theory, and the heterodox tradition of economic thought, this book maps the erotic dimension of capitalism onto concrete economic questions around money, goods, private property, and capital. Yuran offers readers a powerful understanding of capitalism in its unique articulation of love, sex, and money.
