/in /by

In a response to critics who accuseWal-Mart of providing poverty-level wages and a few benefits, Wal-Mart chiefexecutive H.Lee Scott  said Wal-Martoffered good, stable jobs, noting that when it opens a store, more than 3000people often apply for 300 jobs. “It doesn’t make sense”, Mr. Scott said “thatpeople would line up for jobs that are worse than they could get elsewhere,with fewer benefits and less opportunities”. Do you agree with Mr.Scot’s assessment? Explain.

In a recent year, the scores for the reading portion of a test were normally distributed, with a mean oi 20.4 and a standard deviation of 5.5. Complete parts (a)through (d) below. (a) Find the probability that a randomly selected high school student who took the reading portion of the test has a score that is less than 13. The probability ot a student scoring less than 18 is :|.(Round to tour decimal places as needed.) (b) Find the probability that a randomly selected high school student who took the reading portion of the test has a score that is between 13.5 and 27.3. The probability ot a student scoring between 13.5 and 2?.3 is D.(Round to four decimal places as needed.) (c) Find the probability that a randomly selected high school student who took the reading portion of the test has a score that is more than 31.7. The probability ot a student scoring more than 31.? is D.(Round to tour decimal places as needed.) (d) Identify any unusual events. Explain your reasoning. Choose the correct answer below. 0 A. The event in part {a} is unusual because its probability is less than [1.115. O B. The event in part (c) is unusual because its probability is less than 11.05. C) C. None of the events are unusual because all the probabilities are greater than 0.05. O D. The events in parts {a} and (b) are unusual because its probabilities are less than 0.05.

In A Recent Trading Session The Benchmark 30 Year Treasury Bond S Market Price W

/in /by

A. In a recent trading session, the benchmark 30-year Treasury bond’s market price went up A1 dollars per $1000 face value to A2 dollars, while its yield fell from .07 to .068. The bond’s market price then went up another A3 dollars per $1000 face value as the yield fell further to .0665 from .068. Report answers for the following (using average of latest two bond prices for duration and average of latest three bond prices for convexity):

1. Convexity, using the average of all three market prices of the bond in the denominator of the formula.

2. First modified duration, using average of first two market prices of the bond in the denominator of the formula.

3. Second modified duration, using average of second and third prices of the bond.

4. The expected rise in bond price if the interest rate were to fall another 20 basis points (.002) from .0665, using the average of two modified durations and convexity.

B. Estimate term structure of discount factors, spot rates and forward rates by using data on five semi-annual coupon paying bonds with $100 face value each: The bonds, respectively, have 1.25, 5.35, 10.4, 15.15 and 20.2 years to maturity; pay coupon at annual rates of B1, B2, B3, B4, and B5 percent of face value; and are trading at quoted spot market prices in dollars of B6, B7, B8, B9 and B10. Specify the discount factor function d(t) by a third degree polynomial with unknown parameters a, b, and c, as done in class. Using estimated d(t) function, determine spot rate and forward rate functions by assuming half-year compounding. Then write the values of the following based on your estimation.

5. Coefficient of parameter a in first bond price equation.

6. Coefficient of parameter b in first bond price equation.

7. Coefficient of parameter c in first bond price equation.

8. Coefficient of parameter a in second bond price equation.

9. Coefficient of parameter b in second bond price equation.

10.Coefficient of parameter c in second bond price equation.

23.Current price of a dollar at 5th year.

24.Current price of a dollar at 7th year.

25.Current price of a dollar at 10th year.

26.Current price of a dollar at 15th year.

27.Spot rate for term 2 year.

28.Spot rate for term 5 year.

29.Spot rate for term 10 year.

30.Spot rate for term 17 year.

31.Forward rate for half year period 2.5 to 3.0 years.

32.Forward rate for half year period 5.5 to 6.0 years.

33.Forward rate for half year period 10.5 to 11.0 years.

34.Forward rate for half year period 15.5 to 16.0 years.

C. Estimate the 2-year, 5-year, and 10-year key rate durations of a 20-year bond carrying a coupon of C1 percent on face value $100 paid semi-annually. The given term structure starts with C2 percent spot rate of interest at time zero and rises at a rate of 0.002 (.2%) per half year thereafter. Take a 20 basis point (.002) move in each key interest rate to calculate the key rate durations by the method done in class and given in textbook. Report answers for the following:

35. Current fair price of the bond with the given term structure.

36. Price change needed to calculate 2-year key rate duration.

37. Price change needed to calculate 5-year key rate duration.

38. Price change needed to calculate 10-year key rate duration.

39. 2-year key rate duration.
