Some empirical observations of relevance to the analysis of union wage determination

Abstract

Six important empirical characteristics of the union sector need to be incorporated into future research on wage determination. These are 1) the extent of unionization, 2) the statistical correlates of unionization, 3) divergent trends in union and nonunion earnings, 4) union/nonunion wage differentials, 5) the determinants of union and nonunion wage change, and 6) wage imitation. Examination of these characteristics suggests the following about union wage determination. Union wages have advanced relative to nonunion since the mid 1950s, despite relative shrinkage of the union sector. Union wage changes show less sensitivity to business-cycle pressures than nonunion. Limited spheres of wage imitation surround certain major union negotiations. These observations can be fitted into recent analyses of wage determination under long-term employer employee relationships, and have relevance for anti-inflation policy.
