Two firms, A and B, produce goods A and B, respectively. The linear demand function for the two goods are respectively,
Qa = 100 - 4Pa + 1.5Pb
Qb = 120 - 2Pb + 0.5Pa
Production costs are given by Ca (Qa) = 2Qa and Cb (Qb) = 3Qb
The two firms engage in a price war.
A) Derive the equations for the best response functions for each firm
B) Sketch a graph of the best response functions
C) If firm A expects firm B to set its price at $20, what is firm A's best response? If firm B predicts that firm A will price good A at $36, what is firm B's best response?
D) What is the NASH EQUILIBRIUM price and quantity for each firm?
E) How much profit does each firm earn in Nash Equilibrium?
