Suppose an individual faces a decision of whether or not to make an investment 2 years from now. The investment will cost $10,125, and it will yield a benefit b 2 years later. a. Suppose the individual treats a dollar 1 year from now the same way as $0.90 now. How low can b be for this individual to plan to make the investment in two years?

b. Now suppose that the individual's tastes are better characterized by the beta-delta model. Suppose delta is 0.9. For what values of beta will the individual plan the same course of action 2 years from now as he would in the typical delta model (with the same delta)? c. Suppose beta is 0.9 (with delta also equal to 0.9). How low can b be in order for the individual to be willing to undertake the investment when he faces the choice in 2 years? d. For what range of values for b does the individual from (c) plan to undertake the investment but then decides not to when the time comes? What will be an ideal response?
