1. The real risk-free rate (r*) is 2.80% and is expected to remain constant into the future. Inflation is expected to be 6.80% per year for each of the next two years and 5.60% thereafter.

The maturity risk premium (MRP) is determined from the formula: 0.10 x (t – 1)%, where t is the security’s maturity. The liquidity premium (LP) on all National Transmissions Corp.’s bonds is 1.20%. The following table shows the current relationship between bond ratings and default risk premiums (DRP):

Rating

Default Risk Premium

U. S. Treasury —
AAA 0.60%
AA 0.80%
A 1.05%
BBB 1.45%
National Transmissions Corp. issues thirteen-year, AA-rated bonds. What is the yield on one of these bonds? (Hint: Disregard cross-product terms; that is, if averaging is required, use an arithmetic average.)

10.58%

11.78%

6.00%

2. Based on your understanding of the determinants of interest rates, if everything else remains the same, which of the following will be true?

A) The yield on a AAA-rated bond will be lower than the yield on a AA-rated bond.

B) The yield on a AAA-rated bond will be higher than the yield on a BB-rated bond.

Consider the local telephone company, a natural monopoly. the following graph shows the monthly demand curve for phone services and the company’s marginal revenue (mr), marginal cost (mc), and average total cost (atc) curves. 0 2 4 6 8 10 12 14 16 18 20 100 90 80 70 60 50 40 30 20 10 0 price (dollars per subscription) quantity (thousands of subscriptions) d mr mc atc 8, 60 suppose that the government has decided not to regulate this industry, and the firm is free to maximize profits, without constraints. complete the first row of the following table. pricing mechanism short run long-run decision quantity price profit (subscriptions) (dollars per subscription) profit maximization marginal-cost pricing average-cost pricing suppose that the government forces the monopolist to set the price equal to marginal cost. complete the second row of the previous table. suppose that the government forces the monopolist to set the price equal to average total cost. complete the third row of the previous table. under average-cost pricing, the government will raise the price of output whenever a firm’s costs increase, and lower the price whenever a firm’s costs decrease. over time, under the average-cost pricing policy, what will the local telephone company most likely do

Amanager of a store that sells and installs spas wants to prepare a forecast for january and june of next year. her forecasts are a combination of trend and seasonality. she uses the following equation to estimate the trend component of monthly demand: ft = 30+5t, where t = 1 in january of this year. seasonal relatives are 0.60 for january and 1.50 for june. what demands should she predict for january and june of next year

Until recently, hamburgers at the city sports arena cost $4.70 each. the food concessionaire sold an average of 13 comma 000 hamburgers on game night. when the price was raised to $5.40, hamburger sales dropped off to an average of 6 comma 000 per night. (a) assuming a linear demand curve, find the price of a hamburger that will maximize the nightly hamburger revenue. (b) if the concessionaire had fixed costs of $1 comma 500 per night and the variable cost is $0.60 per hamburger, find the price of a hamburger that will maximize the nightly hamburger profit.
