Unions and the financial performance of british private sector establishments

This paper considers the relationship between unions and financial performance using data from the 1980 and 1984 Workplace Industrial Relations Surveys. A qualitative indicator of financial performance is utilized and ordered probit estimates presented. These indicate that unionized establishments are characterized by lower performance levels than are non-union concerns. The interface between union effects and relative market power is also explored and the ability of unions to extract a share of the available rents is found to be greater if the plants in which they are located possess a higher market share.
