Next, assume that some factors changes, such that the expected rate of return, declines by  two percentage points at each prospective level of investment. Assuming no change in the real interest rate, by how much and in what direction will the investment change?  which of the following might cause this change: (a) a decision to increase inventories; (b) an increase in excess production capacity.Suppose that the typical consumer has a salary of $30,000 in 2017. His salary grows by 2% per year. What can we say about his ability to pay for his consumption basket over time? (A) He can never pay for his consumption basket without going into debt. (B) In 2017 and 2018, he can pay for his own consumption, but will be unable to in 2019 and 2020 without taking on debt. (C) From 2017-2019, he can pay for his own consumption, but will be unable to in 2020 without taking on debt. (D) He can always pay for his own consumption basket without taking on debt.
