The following is a demand schedule for shoes:

Price (Per Pair) $120 $100 $80 $60 $40

 

Quantity Demanded 8 15 25 28 30

(in pairs per year)

 

(a) As the price drops from $80 to $60 a pair, is demand elastic or inelastic?

(b) Based on your answer in (a), a shoes salesman should raise or cut price to increase the total revenue?

(b) Assume the wage per worker is $24, please compute the marginal cost of each additional pair from 78 to 81 pairs of jeans.

 

Q9: (5%)

Suppose a company incurs the following costs:

 

Labor $5,000

Equipment $3,000

Materials $1,000

 

It owns the building, so it doesn’t have to pay the usual $2,000 in rent.

(a) What is the total economic cost?

(b) How would accounting and economic costs change if the company sold the building and then leased it back?

Q10: (15%)

Suppose that the monthly market demand schedule for Frisbees is:

 

Price

$8

$7

$6

$5

$4

$3

$2

$1

Quantity Demanded

100

200

400

800

1,600

3,200

6,000

15,000

 

 

Suppose further that the marginal and average costs of Frisbee production for every competitive firm are

Rate of Output

10

20

30

40

50

60

Marginal Cost

$2.00

$3.00

$4.00

$5.00

$6.00

$7.00

Average Cost

$2.00

$2.50

$3.00

$3.50

$4.00

$4.50

 

Finally, assume that the equilibrium market price is $5 per Frisbee.

 

(a) How many Frisbees are being sold in equilibrium?

(b) How many (identical) firms are initially producing Frisbees?

(c) How much profit is the typical firm making?

(d) 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?
