Using a spreadsheet and presenting your results on a single graph, calculate the present value of $1 for every year from the present (0) up to 100 years in the future, for each of the discount rates 0 percent, 1 percent, 5 percent, and 10 percent. What conclusions can you draw from your graph for the relationship of present value to: (i) how far in the future returns are received? (ii) the rate of discount? “Infinity is less than a lifetime.” Comment with respect to your graph.
