Question
Consider a duopoly market with 2 firms. Aggregate demand in this market is given by
Q = 500 – P,
where P is the price on the market. Q is total market output, i.e., Q = QA + QB, where QA is the output by Firm A and QB is the output by Firm B. For both firms, marginal cost is given by MCi = 20, i=A,B.
Assume the firms compete a la Cournot.
