The Impact of Unionization on Productivity: A Case Study

This study examines the effect of unionization on productivity through the use of time-series data on selected establishments in the U.S. cement industry. The analysis combines statistical estimation of the union impact and interviews with union and management officials to forge a link between econometric estimation and the traditional institutional analysis of union policy and management practice. The econometric analysis deals primarily with the problem of controlling for interfirm differences in variables such as the quality of management and also for the possible union impact on labor quality. The case studies are designed to show the specific ways in which unionization affects productivity. The empirical results indicate that unionization leads to productivity gains, deriving in large part from a series of extensive changes in management personnel and procedures.
