You are a manager of company with market power, and your demand and cost functions are given by:
Q = 142,000 – 500P + 6M – 400PR and
C(Q) = 500,000 + 200Q – 0.024Q2 + 0.000006Q2
Where Q is the amount demanded, P is price, M is income, and PR is the price of a related good. The estimated values for M and PRare $25,000 and $200, respectively.
a. What is the profit maximizing (or loss minimizing) output for this firm?
b. What is the firm’s profit maximizing (optimal) price?
c. What are the firm’s maximum profit (loss)?
d. Do you think this firm enjoy much market power? Why?
Q142000 - 50 p+ 6 M- 400 PR (1)
C(Q) 500000 + 200Q -0.024 + 0.000006
now M = 25000
PR = 200
put these values in equation 1
1 ) Q = 142000-500 P +6(25000)-400(200)
Q = 142000-500 P +150000 - 80000
Q = 212000 - 500 P
500 P = 212000 -Q
P =
P = 424 - 0.002 Q equation 2
now TR = PQ
= (424- 0.002 Q)Q
= 424Q - 0.002
so profit maximizing
put
224 = 0.043988 Q
Q =
Q = 5092.29
so profit maximizing output is 5092.29
b) put this value in equation 2
P = 424 -0.002(5092.30)
P =
so the profit maxi maximizing price is
c) now put the value of Q = 5092.30 in equation (3)
so firms profit is
d ) as profit is so heavy
so firm is njoying the market powers.
