to Economic Written Report 6.1 a) Consider a monopoly facing the following demand and MC curves: Demand: P = 12 – 0.002 Q MC: MC = 3 + 0.001 Q (i) Calculate the profit maximizing output of this monopoly. Ans: The output level of monopoly to maximize profit is MR=MC. As‚ P=a-bQ‚ the MR curve will be MR=a-2bQ‚ So‚ 12-2(0.002Q) = 3+0.001Q 12-0.004Q = 3+0.001Q 9 = 0.005Q Q = 1800 Monopoly Price
