Consider a price competition model with two firms, 1 and 2, whose demand functions are as follows:
Q1 =48−3P1 +2P2 Q2 =80−4P2 +3P1
Each firm incurs costs; C1(Q1) = 8Q1 and C2(Q2) = 13Q2.
a) Write down firms 1’s and 2’s profit functions.
b) Compute and graph firms 1’s and 2’s best response functions as a function of the other firm’s prices.
c) Find the Nash equilibrium of the game.
d) Calculate the profit of each firm in the Nash equilibrium.
