This influential collection of essays focuses on the elusive concept of "value," and aims to answer the question "Why is Marx's theory of value so important?" Aboo Aumeeruddy and Ramon Tortajada introduce the key interpretive debates surrounding "value form," leading to seminal essays by Jairus Banaji and Chris Arthur. The labour theory of value is interrogated by Geoffrey Kay and Athar Hussain, and Diane Elson concludes with an argument for the importance of Marx's "Value Theory of Labour." These incisive and erudite texts provide a crucial introduction to Marxist political economy, as well as advancing critical arguments for those already well versed in the field.

Diane Elson is an Emeritus Professor of Sociology at the University of Essex. She writes on Marxist theory, development and human rights. Recently she has made vital contributions to the discourse on economic and social rights and gender inequality.
