Cournot exercises
1. Consider a market with the inverse demand p(Q) = 7 − Q. Two firms operate in this market as Cournot competitors. Both firms have the cost function c(q) = q . Find both firms’ best response functions, and find the Nash equilibrium quantities.
2. Consider a market with the inverse demand p(Q) = 200 − Q. Two firms operate in this market as Cournot competitors. Both firms have the cost function c(q) = 65q . Find both firms’ best response functions, and find the Nash equilibrium quantities.
3. Consider a market with the inverse demand p(y) = 16 − Q. Two firms operate in this market as Cournot competitors. Firm 1 has the cost function c1 (q1 ) = 8q1 . Firm 2 has the cost function c2 (q2 ) = 6q2 . Find both firms’ best response functions, and find the Nash equilibrium quantities.
4. Consider a market with the inverse demand p(Q) = 100 − 2Q. Two firms operate in this market as Cournot competitors. Firm 1 has the cost function c1 (q1 ) = 8q1 . Firm
2 has the cost function c2 (q2 ) = 4q2 . Find both firms’ best response functions, and find the Nash equilibrium quantities.
