Suppose you have been tasked with regulating a single monopoly form that sells 50-pound bags of concrete. The firm has a fixed cost of $30 million per year and a variable cost of $4 per bag no matter how many bags are produced.
a) Average total cost
AFC = Total fixed cost / Quantity
AFC = 30 / 30
AFC = 1
ATC = AFC + AVC
ATC = 1+4
ATC = 5
Here, price is equal to 5 which is equal to average total cost so there will be no profit or loss.
b) AFC = Total fixed cost / Quantity
AFC = 30 / 40
AFC = 0.75
ATC = AFC + AVC
ATC = 0.75+4
ATC = 4.75
Profit = (P-ATC)*Q
Profit = (5-4.75)*30
Profit = $7.5 million
c) ATC = AFC + AVC
ATC = 30 / 40 +4
ATC = 4.75
To earn the fair return, the price should be charged to average total cost which will be equal to 4.75.
Perfectly Inelastic supply occurs when the supply is zero and as the demand increases then the price increases and quantity remains the same. It shows that price and quantity changes due to change in demand curve.
