Suppose that the monthly market demand schedule for Frisbee is
Price | $8 | $7 | $6 | $5 | $4 | $3 | $2 | $1 |
Quantity demanded | 1,000 | 2,000 | 4,000 | 8,000 | 16,000 | 32,000 | 64,000 | 150,000 |
Suppose further that the marginal and average costs of Frisbee production for every competitive firm are
Rate of output | 100 | 200 | 300 | 400 | 500 | 600 |
Marginal cost | $2.00 | $3.00 | $4.00 | $5.00 | $6.00 | $7.00 |
Average total cost | 2.00 | 2.50 | 3.00 | 3.50 | 4.00 | 4.50 |
Finally, assume that the equilibrium market price is $6 per Frisbee.
a) How much profit is the typical firm making?
b) In view of the profits being made, more firms will want to get into Frisbee production. In the long run, these new firms will shift the market supply curve to the right and push the price down to average total cost, thereby eliminating profits. At what equilibrium price are all profits eliminated? How many firms will be producing Frisbees at this price?
a) At a market price of $6
Here
P = Price
ATC = Average total cost
Q = Quantity
Profit = (P-ATC)*Q
Profit = (6-4)*500
Profit = $1000
b) Long-run equilibrium price is the price which is determined at the minimum of average cost which is equal to 2.
At a price of $2
Quantity demanded = 64000
Output = 100 units
Number of firms = 64000 / 100
Number of firms = 640
