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
