An investor is given the opportunity to invest money today and receive $10,000 either 5 years from now or 10 years from now. Assuming the interest rate is positive and constant over the next 10 years, when should he prefer to receive the money? Why?|||Recall the formula for the present value of a single cash flow at the end of period t:
PV = x*(1+i)^-t, where:
PV = present value
x = cash flow at time t
i = effective periodic interest rate (expressed as a decimal, not a percent)
Assuming that i%26gt;0, (1+i)^-t decreases as t increases. Therefore, the PV of a given cash flow at time t decreases as t increases. In other words, the required investment at time 0 in order to get a cash flow at time t gets smaller as the cash flow gets later. Therefore, the investor would prefer to get the $10,000 in 10 years, rather than 5 years.
