# Supply and Demand Essay

Instructions: Round your responses to 2 decimal places.

a. The instant before it pays out current profits as dividends. $ million

b. The instant after it pays out current profits as dividends.

$ million

(page 18)

Explanation:

a. The value of the firm before it pays out current dividends is:

PVfirm = $1,000,000((1 + 0.06) / (0.06 - 0.04) = $52.75 million

b. The value of the firm immediately after paying the dividend

b. Profits grow at an annual rate of 2 percent.

billion

c. Profits grow at an annual rate of 0 percent.

billion

d. Profits decline at an annual rate of 5 percent.

billion Explanation:

a. Since the profits grow faster than the interest rate, the value of the firm would be infinite. This illustrates a limitation of using these simple formulas to estimate the value of a firm when the assumed growth rate is greater than the interest rate.

b. PVfirm = π((1 + i) / (i - g)) = $4.5(1.08 / 0.06) = $81 billion

c. PVfirm = π((1 + i) / (i - g)) = $4.5(1.08 / 0.08) = $60.75 billion

d. PVfirm = π((1 + i) / (i - g)) = $4.5(1.08 / 0.13) = $37.38 billion

7. The demand curve for product X is given by QXd = 420 - 4PX.

a. Find the inverse demand curve.

PX = - QXd

Instructions: Round your answer to the nearest penny (2 decimal places).

b. How much consumer surplus do consumers receive when Px = $50?

$

c. How much consumer surplus do consumers receive when Px = $25?

$

d. In general, what happens to the level of consumer surplus as the price of a good falls?

The level of consumer surplus as the price of a good falls.

Explanation:

a. Solve the demand function for Px to obtain the following inverse demand function: PX = 105 - 0.25QXd.

b. Notice that when Px = $50, QXd = 420 - 4(50) = 220 units. Also, from part a, we know
