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.   What are the equilibrium quantities?  What is the total quantity supplied on this market? What is the equilibrium price in this market?

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.
