‘A Participatory Economy’ presents a fascinating, new alternative to capitalism. It proposes and defends concrete answers to how all society’s economic decisions can be made without resort to unaccountable and inhumane markets (capitalism) or central planning authorities (communism). It explains the viability of early socialism’s vision of an economy in which the workers come together to decide among themselves what to produce and consume. At the same time, Hahnel proposes new features to this economic model including proposing how “reproductive labor” might be socially organized, how to plan investment and long-term development to maximize popular participation and efficiency, and finally, how a participatory economy might engage in international trade and investment without violating its fundamental principles in a world where economic development among nations has been historically unfair and unequal.
