Alienazione e autogestione - Marx’s alienation theory and the firm managed by workers, by Bruno Jossa The paper is about Marx’s theory of alienation and the economics of producer cooperatives. The author argues that alienation has different degrees and that the highest form of it is recorded in capitalism, owing to hired labour. For this reason a labour-managed firm will reduce the alienation. In a system of labour-managed firms, however, alienation will persist, in conseguence of scarsity and the necessity of work for a living. In the paper there is also a discussion of a thesis of Bigo. The last section is about Marx’s idea that capitalism is a world turned upside down. JEL Classification: B14, B5, P13, P14, P2.
