FIGURE 17.3 Labor supply and labor demand in (a) a purely competitive labor market and (b) a single competitive firm. In a purely competitive labor market (a), market labor supply S and market labor demand D determine the equilibrium wage rate W. and the equilibrium number of workers Q.. Each individual competitive firm (b) takes this competitive wage W, as given. Thus, the individual firm's labor supply curve s = MRC is perfectly elastic at the going wage W. Its labor demand curve, d, is its MRP curve (here labeled mrp). The firm maximizes its profit by hiring workers up to where MRP = MRC. Area Oabc represents both the firm's total revenue and its total cost. The green area is its total wage cost the blue area is its nonlabor costs, including a normal profit-that is, the firm's payments to the suppliers of land, capital, and entrepreneurship. ($10) W.
