Changes in Union Wage Effects by Industry: A Fresh Look at the Evidence

Abstract

Unions suffered a modest decline in their capacity to increase wages over nonunion levels between the late 1970s and the middle 1990s according to evidence presented here. The decline in relative wages was significant in only 13 (of 78) industries examined; in 11 industries the differential increased significantly. The industrially disaggregated econometric evidence is broadly consistent with institutional evidence about developments in particular industries; however, more industry-grounded research is clearly warranted.
