If the Fed decreases the money supply at the same time as taxes increase, the:
equilibrium level of output will definitely fall.
In the standard IS-LM model, a decrease in the money supply causes an ______ for real money balance at an initial interest rate, and thus the interest rate has to ______ to equate the quantity money demanded and the money supply, and this shifts the ______.
excess demand; rise; LM curve to the left
According to the market for real money and the IS-LM model, an increase in money supply will cause __________ real money, interest rate must ________ to bring the money market to the equilibrium. Thus, LM curve will shift to the _________.
excess supply of; fall; right
In the classical model with fixed income, if the demand for goods and services is greater than the supply, the interest rate will:
increase
In this graph, starting from the level of capital per worker k1, the amount of capital per worker will: (see graph in Solow Model Practice Problems #7)
increase
The reason that the income response to a fiscal expansion is generallyless in the IS-LM model than it is in the Keynesian-cross model is that the Keynesian-cross model assumes that:
investment is not affected by the interest rate, whereas in the IS-LM model fiscal expansion raises the interest rate and crowds out investment.
In the classical model developed in Chapter 3, when there is an investment incentive scheme that leads to an increased in investment demand,
investment is unchanged, but interest rate rises.
In the classical model, the demand for loanable funds is equivalent to:
investment.
If the production function describing an economy is Y = 100 K0.25L0.75, then the share of total income going to capital owners:
is 25 percent.
If the production function describing an economy is Y = 100 K0.25L0.75, then the share of output going to labor:
is 75 percent.
According to the AD/AS model (assuming the upward-sloping short-run aggregate supply curve), starting from long-run equilibrium, without policy intervention, the long-run impact (based on the self-corrective mechanism) of an adverse supply shock is that:
prices will return to the old level and output will be restored to the natural rate.
Suppose the following equations describe a closed economy: Y=C+I+G C=200+0.75(Y−T) I=200−25r G=100 T=100 Ms=1,000 P=2 (MP)d=Y−100r From the information given above, what are the short-run equilibrium values of r and Y? (Solve for the values of r and Y and write your answers in the space provided.) r* = _____________ Y* = ______________
r* = 6 Y* = 1100
If MPC = 0.75, when G increases by 100 and T increases by 100, then the IS curve for any given interest rate:
shift to the right by 100.
