much is the resulting gain in total surplus? Consider a monopoly market in which the market demand curve is given by P = 120 - 2Q, the marginal revenue curve is MR = 120 - 4Q, the marginal cost curve is MC = 2Q, and there are zero fixed costs. O 600 Suppose the government intervenes and turns the market into a competitive market, and all the firms in the market have the same marginal cost curve as the monopolist, MC = 2Q, and zero fixed costs.
