Abstract
This paper was written during stay at the Centre for Labour Economics at the London School of Economics and I am indebted to Richard Layard, David Metcalf and Steve Nickell for helpful discussions, and to Alan Blinder, John Pencavel and Albert Rees for comments on an earlier draft. Related versions of the paper were presented at the OECD Conference of Experts on the Structural Determinants of Employment and Unemployment, Paris, March 7-11, 1977 and at the Annual Conference of the Association of University Teachers of Economics, Swansea, Wales, March 28-30, 1977. I am indebted for financial support to the Guggenheim Foundation.
