A paper company invests $4m to clear a tract of land and plant some young pine trees The trees will mature in 10 years, at which time the forest will have a market value of $8m What is the expected rate of return for the paper company's investment? A 1987 advertisement in the New Yorker solicited offers on a 1967 Mercury Cougar XR7 (Motor Trend's 1967 car of the year) that had been stored undriven in a climate controlled environment for 20 years If the original owner paid $4000 for this car in 1967, what price would he have to receive in 1987 to obtain a 10 percent annual return on his investment? Vincent Van Gogh sold only one painting during his lifetime, for about $30 A sunflower still life he painted in 1888 sold for $39.85 million in 1988,, more than three times the highest price paid previously for any work of art If this painting had been purchased for $30 in 1888 and sold in 1988 for $39.85 million, what would have been the annual rate of return? In 1940, your grandmother put $1000 into a special trust to be paid to a future grandchild (you) 60 years later, in the year 2000 How much will this trust be worth in the year 2000 if it has been earning 8%?

(Hint: compare the present value of each contract by assuming a range of interest rate, say 8% - 14%) 13 Assume it is now January 1, 2000, and someone offers the following deal: starting from year 2000, you will be paid each year the amount of dollars equal to the year, i.e., $2000, $2001, $2002, until year 3000 inclusive If payments occur at the year end and the interest rate remains at 10%, what is the PV of such a deal? What is the PV if the payments covers only the years from 2000 to 2050 inclusive? What can you conclude for the comparison? 14 When you use the effective annual yield on a semi-annual coupon bond to price the corresponding annual coupon bond, you get the same price? Answers to Addition Exercise Questions on Time Value of Money MGTC03, Prof Jason Z Wei a a b c $530 $561.80 $471.70 $445.00 kmonth = 0.0094888, monthly payment = $307.10 a a b $1210 $1207.50 $1207.50 Generally speaking, if the average returns for different investments are the same, then the one with the smallest variation in returns has the highest total return (hence a) is better than b) or c) b) and c) are the same, because the sequence of returns not matter a b $6,515.58 $5,187,48 $1,241.84 r = 7.18% $26,910 r = 15.14% $101,257 and $897,597 10 $268,923.89 11 a b c d $385,543.29 $8,518.55 $72.57 $0.618 12 Interest rate 8.00% 9.00% 10.00% 11.00% 12.00% 13.00% 14.00% PV of A ($m) $7.9854 $7.7793 $7.5816 $7.3918 $7.2096 $7.0345 $6.8662 PV of B ($m) $8.0762 $7.7892 $7.5163 $7.2566 $7.0093 $6.7738 $6.5493 Choice B B A A A A A 13 PV = 2000/1.1 + 2001/1.12 + 2002 /1.13 + … + 3000 /1.11001 (1) Multiply both sides by (1.1): PV(1.1) = 2000 + 2001/1.1 + 2002/1.12 + 2003 /1.13 + … + 3000 /1.11000 (2) Subtract (1) from (2): PV(0.1) = 2000 + 1/1.1 + 1/1.12 + … + 1/ 1.11000 !3000 /1.11001 (3) Notice that the middle part of (3) is an annuity of one dollar for 1000 years Therefore, PV(0.1) = 2000 + PVIFA10%, 1000 ! 3000 /1.11001 (4) Therefore, PV = 2010 / (0.1) = $20,100 When the deal covers only 2000 - 2050, we only need to replace the number of periods in (4) by 50 and 51, and replace the last payment by $2050: PV(0.1) = 2000 + PVIFA10%, 50 ! 2050 /1.151 = 1994.04 Therefore, PV = 1994.04 / (0.1) = $19,940.40 The difference between the two cases is only $20,100 - $19,940.40 = $159.60 Implication: Money promised beyond 50 years is practically worthless! 14 The answer is no For example, suppose the price for a two-year, 10% coupon (paid semiannually) bond is $965.35 Then the semi-annual yield, k can be solved from 965.35 = 50/(1+k) + 50/(1+k)2 + 50/(1+k)3 + 1050/(1+k)4 to obtain k = 0.06 Therefore the effective annual yield is, (1 + 0.06)2 - = 0.1236 Using this yield to price the same bond assuming the coupon is paid annually, we get 100/(1 + 0.1236) + 1100 / (1 + 0.1236)2 = 960.30, which is different from 965.35 Why? The reason lies in interest on interest Although we are using the effective annual yield to discount the annual coupon, we can not take into account the fact that we are not earning the interest on interest when the coupons are paid semi-annually For example, look at the first annual coupon In the case of semi-annual payment, we get $50 every months, and in the annual case, we get $100 in one year Let k be the semi-annual yield Then, the present value of the coupon in the first case is, 50/(1+k) + 50/(1+k)2 ; and that for the second case is 100/(1+k)2, which can be re-written as 50/(1+k)2 + 50/(1+k)2 We can easily see that the second expression is smaller, since we missed the interest on the first half of the coupon earned in the second 6-month period ... annual coupon bond, you get the same price?
