Abstract

Popular characterizations of union preferences assume that the income of laid-off union members is exogenous. There is evidence, however, of intra-union distribution schemes such as severance payments, unemployment insurance, retraining arrangements and early retirement schemes. This paper develops a model of wage and severance pay determination by a trade union and a firm bargaining in a right-to-manage framework. The important point differentiating the model in this paper from the orthodox union model is that it is efficiency-improving in the sense that it makes full-insurance possible and marginal productivity is equal to the opportunity cost of labour. Moreover, with redundancy pay on the bargaining agenda, both the right-to-manage and the efficient bargaining union models are characterized by the same efficiency conditions. This has implications for empirical research which attempts to distinguish between these two models, since the outcome of both models is the same. Finally, the union-firm bargaining model can also be compared with the outcome of the implicit contract model with redundancy pay. There is an important difference between the two approaches, however. While the result in this paper derives from an imperfectly competitive labour market where unions and firms bargain over wages and redundancy pay, the implicit contract result derives from a perfectly competitive labour market in which competitive forces lead to an efficient outcome.
