If, like a typical profit-maximizing seller with market power, the union aims to maximize total “profit” for union members, it will supply the quantity of labor L₁ at point a, where the marginal cost curve and marginal revenue curve intersect. At this quantity, the wage will be W₁, the wage indicated by the labor demand curve, L^D. If the union instead aims to maximize total wage earnings, it would sell at point b, where the union’s marginal revenue equals 0. At this point, the quantity of labor supplied would be L₂ and the wage would equal W₂. Point c represents the competitive market equilibrium, where the labor demand and marginal cost curves intersect. The competitive market wage is W_C and quantity of labor is L_C. Thus, regardless of the union’s goal, it will supply a smaller quantity of labor to the market at a higher wage than in the competitive equilibrium.
