Altruism, union utility and outsiders Available to Purchase

Provides a general approach for the incorporation of the influence of insiders and outsiders in the union utility. In particular, the specification is such that the weight of the influence of the outsiders can vary; and this makes it possible to consider different degrees of union altruism and also to embrace all the previous work on the subject. Examines both the monopoly union and the efficient bargain cases. Comparative statics analysis provides some interesting results, such as that wages are more inflexible downwards.
