Most large firms are controlled by shareholders, who choose the board of directors and can replace the firms management. In rare instances, however, control over the firm rests with the workforce. Many explanations for the rarity of workers’ control have been offered, but there have been few attempts to assess these hypotheses in a systematic way. This book draws upon economic theory, statistical evidence, and case studies to frame an explanation. The fundamental idea is that labor is inalienable, while capital can be freely transferred from one person to another. This implies that worker controlled firms typically face financing problems, encounter collective choice dilemmas, and have difficulty creating markets for control positions within the firm. Together these factors can account for much of what is known about the incidence, behavior, and design of worker- controlled firms. A policy proposal to encourage employee buyouts is developed in the concluding chapter.
