Industrial Economics Homework

Problem 1: A typical bank offers you a Visa credit card that charges interest on unpaid balance at 1.5% per month compounded monthly. This means that the nominal interest (annual percentage) rate for this account is A and the effective annual interest rate is B. Suppose your beginning balance was $500 and you make only the required minimum monthly payment (payable at the end of each month) of $20 for the next 3 months. If you made no new purchases with this card during this period, your unpaid balance (after your 3^rd payment) will be C at the end of 3 months. What are the values of A, B, and C?

Problem 2: In January 1989, C&S, the largest mutual saving bank in Georgia, published the following information: interest, 7.55%; effective annual yield, 7.842%. The bank did not explain how the 7.55% is connected to the 7.842%, but you can figure out that the compounding scheme used by the bank should be ________.

Problem 8: While snooping around in Professor Sadighian's office, Jason uncovered an equation that describes the conversion of a cash flow into an equivalent equal-payment series with n = 8. Help him figure out the original cash flow by drawing the original cash flow diagram. Assume an interest rate of 10% compounded annually.

Problem 9: For computing the equivalent equal-payment series (A) of the following cash flow with i = 10%, which of the following statements is (are) correct?

a. A=100(F/A, 21%, 4)(A/F, 10%, 8)

b. A=[100(P/F, 10%, 2) + 100(P/F, 10%, 4) + 100(P/F, 10%,6) + 100(P/F, 10%, 8)](A/P, 10%, 8)

c. A=100(A/F, 10%, 2)

d. A=[100(F/P, 10%, 2) + 100(F/P, 10%, 4) + 100(F/P, 10%,6) + 100(F/P, 10%, 8)](P/F, 10%, 10)(A/F, 10%, 8)

e. A=100(F/A, 10%, 4)(A/F, 10%, 8)

f. A=100(P/A, 21%, 4)(A/P, 10%, 8)

g. A=100(P/A, 10%, 4)(A/P, 10%, 8)

Problem 10: A couple with a 7-year-old daughter wants to save for their child's college expenses in advance. Assuming that the child enters college at the age 18 (the couple has 11 year to collect the money). They estimate that an amount of $24,000 per year in terms of today's dollars will be required to support the child's college expenses for 4 years. The future inflation rate is estimated to be 8% per year and they can invest their savings at 12% compounded monthly.

a. Determine the equal monthly amounts the couple must save until they send their child to college.

b. If the couple has decided to save only $1,000 each quarter, how much will the child have to borrow each year to support her college education?

Problem 11: Suppose you have the choice of investing in (1) a municipal bond that costs $1,000 today, pays $67 in interest semiannually, and matures at the end of 5 years or (2) zero-coupon bond that costs $525 today, pays nothing during its life, and then pays $1,000 after 5 years. Which bond would provide the higher yield to maturity (or return on your investment)?

Problem 12: NPI Corp., ice cube producer company, generates a continuous constant after-tax cash flow at the rate f(t) = $250,000 for a 10-year planning horizon.

a. Find the present value of this cash flow stream over 10 years at 12% compounded continuously.

b. The profit per year is expected to increase continuously because of increased productivity and the new cash flow rate can be expressed as f(t) = 250,000(2.0-e^-0.2t) where t is time in year. Find the present value of this cash flow stream.

c. Productivity increases as in part b, but competition reduces the profit continuously by 8% per year. Find the present value of the cash flow.

Problem 13: State the immediate effect (increase, decrease, no effect) of the following transactions on:

a. Current Ratio (assume current ratio = 1 at start of each question)

c. Working Capital

d. ROE
