UNION MEMBERSHIP, COLLECTIVE-BARGAINING COVERAGE AND THE TRADE-UNION MARK-UP FOR BRITAIN

This paper estimates the union mark-up using British General Household Survey data. The wage gap is decomposed both for the mean and the variance of the earnings distribution. The results indicate that the union mark up is larger than previously estimated and that structural effects account for a major part of the differences that are found in the earnings distributions of covered union members, covered non-unionists and uncovered non-unionists. © 1991.
