The economics of worker cooperatives is a branch of economic inquiry with a long and esteemed pedigree, dating at least from the work of John Stuart Mill in the mid-nineteenth century. Since then, leading economists have paid intermittent attention to the topic, but the collapse of state-sponsored socialism in Eastern Europe and growing discontent with loosely-fettered capitalism have resulted in a resurgence of interest in worker co-operatives as a method of enhancing productivity and reducing income inequalities without heavy government regulation.
