With a growing prominence ofsophisticated econometric research in a much-expanded field of New Economics ofParticipation (NEP), it is of particular value to learn about real-worldexamples of participatory and labor-managed firms in the advanced market economiesthrough extensive case studies. In this volume of Advances in the Economic Analysis of Participatory and Labor-ManagedFirms, the authors present such case studies. The real-world examples ofparticipatory organizations described vividly in this volume will helpresearchers in NEP to design empirical strategies better, and to interprettheir econometric results more sensibly. Furthermore, they will helppolicymakers and practitioners in their efforts to construct better publicpolicy and design management practices.
