Question 21
A monopolist can produce at a constant average (and marginal) cost of AC = MC = $5. It faces a market demand curve given by Q = 53 – P.
Based on the above data, answer the given subquestions.
Suppose a second firm enters the market. Let Q1 be the output of the first firm and Q2 be the output of the second. Market demand is now given by Q1 + Q2 = 53 – P. Assuming that this second firm has the same costs as the first and the firms are competing as per the Cournot competition, find out the equilibrium quantity for both firms, equilibrium price and difference in profit of a firm compared to monopolist case.
