pdt (830 KB) @ (UCL-SlbQ/l) Demand faced by a monopolist is Q : 20 0.5P. Her marginal cost is 10. Based on this information we can say that: (A) The optimal production of the monopolist is Q = 15. k (B) The price charged by the monopolist is equal to her marginal cost. (C) The deadweight loss associated with the monopolist's choice of price is less than the product of the difference between her price and marginal cost, multiplied by her optimal quantity. (D) If instead of a monopolist, the market is under perfect competition, then the optimal production of this tiny rm would be Q = 7.5
