PRODUCT MARKET COMPETITION, PROFIT SHARING AND EQUILIBRIUM UNEMPLOYMENT***

Preliminary version We investigate the implications of product market imperfections on profit sharing, wage negotiation and equilibrium unemployment. The optimal profit share, which the firms use as a wage-moderating commitment device, is below the bargaining power of the trade union. Intensified product market competition decreases profit sharing, but increases the negotiated base wage, because the wage-increasing effect of reduced profit sharing dominates the wage-reducing effect associated with a higher wage elasticity of labor demand. Finally, we show that intensified product market competition does not necessarily reduce equilibrium unemployment, because it induces both higher wage mark-ups and lower optimal profit shares
