This paper examines how shared capitalism compensation systems - those that link employee pay to company performance - affect diverse employee outcomes. It uses two data sets: the national GSS survey that provides a broad representative view of the extent of the programs; and the NBER Shared Capitalism Project surveys of workers in 14 companies that use shared capitalism programs extensively. We find that greater involvement in the programs is generally linked to greater participation in decisions, higher quality supervision and treatment of employees, more training, higher pay and benefits, greater job security, and higher job satisfaction. We also find positive interactions of shared capitalism with high-performance policies in predicting participation in decisions and overall job satisfaction, and negative interactions of shared capitalism with close supervision in affecting almost all of the outcomes. Overall the results support the idea that workers can gain by sharing, but whether this happens is contingent on other workplace policies.
