A reduction in the real interest rate will increase investment spending, other things equal, because firms will make an investment purchase only if the expected return is

greater than or equal to the real interest rate at which it can borrow.

If a $50 billion initial increase in spending leads to a $250 billion change in real GDP, how big is the multiplier?

5.0

A downshift of the consumption schedule typically involves an equal upshift of the saving schedule. The exception to this relationship occurs when

upward downward

A substantial increase in household borrowing to finance auto purchases. The consumption schedule will shift ___________ The saving schedule will shift ___________

upward downward

Assume there are no investment projects in the economy that yield an expected rate of return of 25 percent or more. But suppose there are $10 billion of investment projects yielding expected returns of between 20 and 25 percent; another $10 billion yielding between 15 and 20 percent; another $10 billion yielding between 10 and 15 percent; and so forth. a. Cumulate these data and present them graphically using the graph below, putting the expected rate of return (and the real interest rate) on the vertical axis and the amount of investment on the horizontal axis.

Draw this relationship between the expected rate of return and the amount of investment expenditure. Plot points 0,25 10,20 20,15 30,10 40,55 0,0 What will be the equilibrium level of aggregate investment if the real interest rate is as follows: 15 percent: 20 Billion 10 percent: 30 Billion 5 percent: 40 Billion

The difference between the MPC and the APC is that

the MPC is the change in consumption divided by the change in income, whereas the APC is total consumption divided by total income.
