1.If Consolidated Power is priced at $50.00 with dividend, and its price falls to $46.50 when a dividend of $5.00 is paid, what is the implied marginal rate of personal taxes for its stockholders? Assume that the tax on capital gains is 40% of the personal income tax.
2. You are comparing the dividend policies of three dividend-paying utilities. You have collected the following information on the ex-dividend behavior of these firms. NE Gas SE Bell Western Electric Price before 50 70 100 Price after 48 67 95 Dividends/share 4 4 5 If you were a tax-exempt investor, which company would you use to make “dividend arbitrage” profits? How would you go about doing so?
3. Southern Rail has just declared a dividend of $1. The average investor in Southern Rail faces an ordinary tax rate of 50%. Although the capital gains rate is also 50%, it is believed that the investor gets the advantage of deferring this tax until future years (the effective capital gains rate will therefore be 50% discounted back to the present). If the price of the stock before the ex-dividend day is $10 and it drops to $9.20 by the end of the ex-dividend day, how many years is the average investor deferring capital gains taxes? (Assume that the opportunity cost used by the investor in evaluating future cash flows is 10%.)
4. LMN Corporation, a real estate company, is planning to pay a dividend of $0.50 per share. Most of the investors in LMN are other corporations that pay 40% of their ordinary income and 28% of their capital gains as taxes. However, they are allowed to exempt 85% of the dividends they receive from taxes. If the shares are selling at $10 per share, how much would you expect the stock price to drop on the ex-dividend day?
9. WeeMart, a retailer of children’s clothes, announces a cut in dividends following a year in which both revenues and earnings dropped significantly. How would you expect its stock price to react? Explain.

1. The US Department of Education was established as a new cabinet department in 1982. College costs (tuition, room, board, books, expenses), after adjustment for inflation, have gone up from $8,000 in 1980 to more than $20,000 today. Is this a coincidence? Discuss how the government may be helping colleges raise total costs through collusive behavior and first-degree price discrimination.
2. Drug firms engage in third-degree price discrimination when they sell their products overseas for a lower price than in the US. Why do drug firms choose to serve markets in which the price is controlled, such as Canada? How did they get the US FDA to help them keep the two markets separate (high demanders in the US, low demanders in Canada)?
3. Concert promoters are monopolists, yet they often choose not to charge the profit-maximizing price for their concerts. Explain and illustrate with one or more diagrams how they set ticket prices, the impact their decision has on the size of the crowd, and the opportunity this situation creates for ticket scalpers.
