18. Dividends and Taxes. Investors require an after-tax rate of return of 10% on their stock invest- ments. Assume that the tax rate on dividends is 30% while capital gains escape taxation. A firm will pay a $2 per share dividend 1 year from now, after which it is expected to sell at a price of $20. (LO5)

a. Find the current price of the stock.

b. Find the expected before-tax rate of return for a 1-year holding period.

c. Now suppose that the dividend will be $3 per share. If the expected after-tax rate of return is still 10%, and investors still expect the stock to sell at $20 in 1 year, at what price must the stock now sell?

d. What is the before-tax rate of return? Why is it now higher than in part (b)?
