ABC Co is estimating next year’s profit. Due to the presidential election and pandemic market demand is uncertain. The estimated inverse demand that shows that 40% of the time P=5,000 – 10Q and the 60% time P= 4,000 – 20Q. The firm’s cost function is C(Q) = 100,000+ 400Q. What is the expected profit maximizing quantity and expected profit?
The estimated inverse demand shows that 40% of the time P = 5,000 - 10Q and the 60% of the time P = 4,000 - 20Q
Derive expected demand function -
P = [0.40 * (5,000 - 10Q)] + [0.60 * (4,000 - 20Q)]
P = [2,000 - 4Q] + [2,400 - 12Q]
P = 4,400 - 16Q
Derive the expected total revenue -
TR = P * Q = [4,400 - 16Q] * Q = 4,400Q - 16Q2
Derive the expected marginal revenue -
MR = dTR/dQ
MR = d(4,400Q - 16Q2)/dQ
MR = 4,400 - 32Q
Total cost function is as follows -
TC = 100,000 + 400Q
Derive the marginal cost function -
MC = dTC/dQ
MC = d(100,000 + 400Q)/dQ
MC = 400
Profit-maximization condition is as follows -
MR = MC
4,400 - 32Q = 400
32Q = 4,000
Q = 4,000/32 = 125
The expected profit-maximizing quantity is 125 units.
Calculate the expected profit -
Expected profit = Total revenue - Total cost
Expected profit = [4,400Q - 16Q2] - [100,000 + 400Q]
Expected profit = [(4,400 * 125) - 16(125)2] - [100,000 + (400 * 125)]
Expected profit = 300,000 - 150,000
Expected profit = 150,000
The expected profit is $150,000.
