A³
d. Using the profit function above and assuming that firm A produces QĄ, calculate what
firm B's best response is to firm A's decision to produce QA-
Note: Firm B's best response should be a function of QA

1. Best responses in a Cournot Oligopoly
Firm A and Firm B sell identical goods
Total market demand for the good is:
The inverse demand function is therefore
Q(P) = 35, 100 - 45P
P(QM) = 780 - Q = 780 -0.02222QM
1
45
QM is total market production (i.e., combined production of firm's A and B.
That is:
P(QA, QB) = 780-
As a result, the inverse demand curve for each firm is:
1
LA
2M = A +QB
-QB = 780 -0.02222QA -0.02222QB

Unlike the example in class, the two firms have different costs.
TCA (QA) = 4000A
TCB (QB) = 260QB
a. Using the demand function and the cost functions above, what is firm A's profit
function.
b. Using the profit function above and assuming that firm B produces QB, calculate what
firm A's best response is to firm B's decision to produce QB-
Note: Firm A's best response should be a function of
c. Using the demand function and the cost functions above, what is firm B's profit
function
