Question
Suppose that the real interest rate is 6%. 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.
FIGURE 10.5 The investment demand curve. The investment demand curve is constructed by arraying all potential investment projects in descending
order of their expected rates of return. The curve slopes downward, reflecting an inverse relationship between the real interest rate (the financial "price" of
each dollar of investing) and the quantity of investment demanded.
