Essay Questions

104. Discuss the statement, "Money has a time value." Money has a time value due to the concept of opportunity cost. In other words, if receipt of funds is forgone until a later period, you lose the opportunity to earn a return on the funds in the interim. Thus, cash flows that occur in different periods cannot be directly compared without adjusting for these opportunity costs. Discounting cash flows to a common period adjusts for the time value, and makes cash flows comparable.

105. Would you prefer a savings account that paid 7% interest, compounded quarterly, over an account that paid 7.5% with annual compounding if you had \$1,000 to deposit? Would the answer change if you had \$100,000 to deposit? FV = (1 + i)n for simple interest FV = (1 + i/m)nxm for compound interest Then, FV = (1 + .07/4)1 x 4 = 1.0719 Versus FV = (1 + 0.75)1 = 1.075 Thus, the 7.5% account will earn .31% more in the first year than the 7% account with quarterly compounding. The amount to be deposited will not change your preference: In this case the compounding is not enough to overcome the difference in APR.

After the first year's addition of interest, the account has \$1,090.00 and \$395.06 is withdrawn to make the first payment. The balance of \$694.94 grows to \$757.48 at the end of the second year.

110. Some home loans involve "points," which are fees charged by the lender. Each point charged means that the borrower must pay 1% of the loan amount as a fee. For example, if 0.5 point is charged on a \$100,000 loan, the loan repayment schedule is calculated on the \$100,000 loan, but the net amount the borrower receives is only \$99,500. What is the effective annual interest rate charged on such a loan, assuming that loan repayment occurs over 360 months, and that the interest rate is 1% per month? Since the monthly payment is based on a \$100,000 loan: Mortgage payment  annuity factor(1%, 360) = 100,000 monthly mortgage payment = \$1,028.61 The net amount received is \$99,500. Therefore: \$1,028.61  annuity factor(r, 360) = \$99,500 r = 1.006% per month The effective annual rate is: (1.01006)12 - 1 = 0.1276 = 12.76%

111. In 1973 Gordon Moore, one of Intel's founders, predicted that the number of transistors that could be placed on a single silicon chip would double every 18 months, equivalent to an annual growth of 59% (i.e., 1.591.5 = 2.0). The first microprocessor was built in 1971 and had 2,250 transistors. By 2003 Intel chips contained 410 million transistors, over 182,000 times the number 32 years earlier. What has been the annual compound rate of growth in processing power? How does it compare with the prediction of Moore's law? Call g the annual growth rate of transistors over the 32-year period between 1971 and 2003. Then 2,250  (1 + g)32 = 410,000,000 (1 + g)32 = 182,222 1 + g = 182,2221/32 = 1.46 So the actual growth rate has been g = .46, or 46%, not quite as high as Moore's prediction, but not so shabby either.

112. How should we compare interest rates quoted over different time intervals—for example, monthly versus annual rates? Interest rates for short time periods are often quoted as annual rates by multiplying the period rate by the number of periods in a year. These annual percentage rates (APRs) do not recognize the effect of compound interest; that is, they annualize assuming simple interest. The effective annual rate annualizes using compound interest. It equals the rate of interest per period compounded for the number of periods in a year.

A point is reached where the benefit of more frequent compounding is overshadowed by the reduction in APR.

114. After reading the fine print in your credit card agreement, you find that the "low" interest rate is actually an 18% APR, or 1.5% per month. Now, to make you feel even worse, calculate the effective annual interest rate.

115. Why is it difficult and perhaps risky to evaluate financial projects based on APR alone? Evaluating a project by APR alone ignores the potential significant effects that accrue as a result of compounding on a more frequent than annual basis. For example, over a long period of time there is a significant difference to the value of an account that carries monthly as opposed to annual compounding. In a similar manner, the cost of a loan can best be evaluated through the effective annual rate that considers the cost of payments occurring more frequently than annually.

116. What is the difference between real and nominal cash flows and between real and nominal interest rates? A dollar is a dollar, but the amount of goods that a dollar can buy is eroded by inflation. If prices double, the real value of a dollar halves. Financial managers and economists often find it helpful to re-express future cash flows in terms of real dollars—that is, dollars of constant purchasing power. Be careful to distinguish the nominal interest rate and the real interest rate—the rate at which the real value of the investment grows. Discount nominal cash flows (that is, cash flows measured in current dollars) at nominal interest rates; discount real cash flows (cash flows measured in constant dollars) at real interest rates. Never mix and match nominal and real.

117. What problem can be caused by "mixing" real and nominal cash flows in discounting exercises? One of the primary components of a nominal interest rate is a premium for the rate of inflation that is expected during the time period that the interest rate is in effect. On the other hand, the adjustment that takes a nominal rate to a real rate is typically a downward adjustment that "backs out" the expected impact of inflation. Thus, to discount real flows with a nominal rate would be to overcompensate for the effects of inflation. Alternatively, to discount nominal flows with a real rate would be to under compensate for inflationary impact. The only safe, correct method is to discount nominal flows with nominal rates, or discount real flows with real rates.

118. In 2004 there was widespread dismay as the price of unleaded gasoline climbed to \$2.03 a gallon. Motorists looked back longingly to 20 years earlier when they were paying just \$1.19 a gallon. But how much had the real price of gasoline changed over this period, if the consumer price index was 1.81 times itself in 1984? In 2004 the consumer price index was 1.81 times its level in 1984. If the price of gasoline had risen in line with inflation, it would have cost 1.81  \$1.19 = \$2.15 a gallon in 2004. That was the cost of gasoline 20 years ago but measured in terms of 2004 dollars rather than 1984 dollars. Thus over the 20 years the real price of gasoline declined from \$2.15 a gallon to \$2.03, a fall of 6%.
