Question

An increase in interest rates will generally lower the prices of assets. To see this, calculate the present value of the following two assets at interest rates of 5 percent, 10 percent, and 20 percent per year: a. A perpetuity yielding $\$ 100$ per year b. A Christmas tree that will sell for $\$ 50$ one year from now Explain why the price of the long-lived asset is more sensitive to interest-rate changes than the price of the short-lived asset.

Step 1

The present value is the current worth of a future sum of money or stream of cash flows given a specified rate of return. The present value of a perpetuity can be calculated using the formula: \[PV = \frac{C}{r}\] where \(C\) is the cash flow per period and  Show more…

Key Concepts

-
Present Value
Present value is the current worth of a future stream of cash flows discounted at a chosen interest rate. It is a fundamental concept in finance because it allows investors to determine how much a future payment or series of payments is worth today, reflecting the time value of money.
Interest Rate Sensitivity
Interest rate sensitivity refers to the degree to which the present value of an asset changes in response to changes in the discount rate. Assets with cash flows that extend further into the future exhibit greater sensitivity because a small change in the rate has a more pronounced effect when discounting distant cash flows.
Time Value of Money
The time value of money is the principle that a sum of money today is worth more than the same sum in the future due to its earning potential. This concept is key to understanding why future cash flows are discounted to determine their present value, and why assets with longer time horizons are more affected by changes in interest rates.

a-what-is-the-present-value-of-a-1000-bond-which-pays-50-a-year-for-10-years-starting-one-year-fro-3

(a) What is the present value of a $\$ 1000$ bond which pays $\$ 50$ a year for 10 years, starting one year from now? Assume the interest rate is $5 \%$ per year, compounded annually. (b) since $\$ 50$ is $5 \%$ of $\$ 1000,$ this bond is called a $5 \%$ bond. What does your answer to part (a) tell you about the relationship between the principal and the present value of this bond if the interest rate is $5 \% ?$ (c) If the interest rate is more than $5 \%$ per year, compounded annually, which is larger: the principal or the present value of the bond? Why is the bond then described as trading at a discount? (d) If the interest rate is less than $5 \%$ per year, compounded annually, why is the bond described as trading at a premium?

Consider an asset that costs $120$dollars today. You are going to hold it for 1 year and then sell it. Suppose that there is a 25 percent chance that it will be worth $100$dollars in a year, a 25 percent chance that it will be worth $115$dollars in a year, and a 50 percent chance that it will be worth $140$ dollars in a year. What is its average expected rate of return? Next, figure out what the investment's average expected rate of return would be if its current price were $130$ dollars today. Does the increase in the current price increase or decrease the asset's average expected rate of return? At what price would the asset have a zero rate of return?
