Abstract
Using meta-analytic techniques, the author synthesizes the results of 43 published studies to investigate the effects on productivity of various forms of worker participation: worker participation in decision making; mandated codetermination; profit sharing; worker ownership (employee stock ownership or individual worker ownership of the firm's assets); and collective ownership of assets (workers' collective ownership of reserves over which they have no individual claim). He finds that codetermination laws are negatively associated with productivity, but profit sharing, worker ownership, and worker participation in decision making are all positively associated with productivity. All the observed correlations are stronger among labor-managed firms (firms owned and controlled by workers) than among participatory capitalist firms (firms adopting one or more participation schemes involving employees, such as ESOPs or quality circles).
