# solve for net present value

Question 2

A doctor spent two weeks doing charity medical work in Mexico. In calculating her taxable income for the year, her accountant deducted as business expenses her round-trip airline ticket, meals, and hotel bill for the two-week stay. She was surprised to learn that the accountant, following IRS rules, could no deduct as cost of the trip the $8,000 of income she lost by being absent from her medical practice for two weeks. She asked the accountant, "Since lost income is not deductible as an expense, should I ignore it when I make my decision next year to go to Mexico for charity work?" Can you give the doctor some advice on decision making?

Question 5

An article in The Wall Street Journal discusses a trend among some large U.S. corporations to base the compensation of outside members of their boards of director partly on the performance of the corporations. "This growing practice more closely aligns the director to the company. (Some) companies link certain stock or stock-option grants for directors to improved financial performance, using a measure such as annual return on equity."

How would such a linkage tend to reduce the agency problem between managers and shareholders as a whole? Why could directors be more efficient than shareholders at improving managerial performance and changing their incentives?

Question 7

Fortune magazine reported that SkyWest, an independent regional airline, negotiated a financial arrangement with Delta and United to provide regional jet service for the two major airlines. For its part of the deal, SkyWest agreed to paint its jets the colors of Delta Connection and United Express and to fly routes specified by the two airlines. In return, Delta and United agreed to pay SkyWest a predetermined profit margin and to cover most of the regional airline's costs. Fortune explained that while the deal limited volatility in earnings since Delta and United covered SkyWest's fuel costs, increased its load factor (the percentage of seats occupied), and managed its ticket prices.

Fortune suggested that Wall Street liked the deal because SkyWest's market valuation instead from $143 million to $1.1 billion after it began its service with the two major airlines. Explain carefully how this arrangement with Delta and United could have caused the value of SkyWest to increase dramatically even though it limited the amount of profit SkyWest could earn.

14) A manufacturer must decide whether to build a small or a large plant at a new location. Demand at the location

can be either small or large, with probabilities estimated to be 0.4 and 0.6 respectively. If a small plant is built,

and demand is large, the production manager may choose to maintain the current size or to expand. The net

present value of profits is $223,000 if the firm chooses not to expand. However, if the firm chooses to expand,

there is a 50% chance that the net present value of the returns will be 330,000 and 50% chance the estimated net

present value of profits will be $210,000. If a small facility is built and demand is small, there is no reason to

expand and the net present value of the profits is $200,000. However, if a large facility is built and the demand

and the demand turns out to be small, the choice is to do nothing with a net present value of $40,000 or to

stimulate demand through local advertising. The response to advertising can be either modest with a

probability of .3 or favorable with a probability of .7. If the response to advertising is modest the net present

value of the profits is $20,000. However, if the response to advertising is favorable, then the net present value of

the profits is$220,000. Finally, the when large plant is built and the demand happens to be high, the net present

value of the profits $800,000. Draw a decision tree and determine the payoff for each decision and event node.

Which alternative should the manufacturer choose and what is the expected value?
