In an industry with a dominant structure, firms with fringe competition are known to have: The market demand function Q = D(P) = 200 - P, while the supply function of several other small competitive firms Q = S(P) = P - 40. The marginal cost function of dominant firm MC = AC = 40. a. Derive the residual demand function for the dominant firm, calculate its marginal cost, determine its price and the amount of production that maximizes its profit. b. Calculate the amount of production offered by other small competitive firms and the total production in that industry Lastly, compare consumer surplus in a market structure like this with a monopoly
