Abstract: The paper describes the growth and organization of workers' production co-operatives in Denmark. Various theoretical propositions concerning workers' co-operatives are tested empirically. All these propositions entail comparisons between co-operatives and conventional firms in the same industry and are concerned with firms' lifespans, scale elasticities, factor intensities and productivity. In the light of empirical findings the paper briefly discusses the applicability to workers' co-operatives of the theory of labour-managed firms.
