A. A perfect competitive market has the following demand curve QD = 200- P. Suppose this perfectly competitive market has now became a monopoly with the following demand curve P = 400 2Q The monopoly marginal cost curve is MC = 4Q, and the competitive market supply curve is QSP. Calculate the monopolist deadweight loss (DWL). - B. Explain what happens for a firm in a perfectly competitive market if the price of the product they sell is greater than its average cost. (Draw all the necessary curves, show whether the firm exhibits positive, negative, or zero profit and explain the reason). C. A monopolist has a TC = 2F + 80Q function is operating in a given industry, where F represents the fixed costs. Q = 120-P is the demand function for this monopolist. Knowing that when the price is 120 their total profit is zero, what will be their total profit if they charge the profit maximizing price?
