This paper examines the introduction of monopolistic competition into wage bargaining models : in addition to capital-labour substitution, we also consider a cost-push effect. The right-to-manage model requires strong restrictions on the objective functions and leads to problematic conclusions because the wage claims of the union are generally not compatible with the mark-up requirement contained in the firm’s price equation. In the efficient bargaining model, the union negotiates also the employment level, which gives it a way of extracting part of the monopoly rent : the firm’s commitment to an efficient wage-employment combination forces it to follow a pricing rule such that part of the surplus is transferred to the union.
