Macroeconomics Ch 9
The FE line shows the level of output at which the ________ market is in equilibrium.
Labor
The FE line
is vertical.
The FE line is vertical because the level of output at full employment doesn’t depend on the
real interest rate.
Which of the following would shift the FE line to the right?
An increase in labor supply
Which of the following would shift the FE line to the left?
A decrease in the capital stock
An increase in the money supply would cause the FE line to
remain unchanged.
An increase in investment spending would cause the FE line to
remain unchanged.
An adverse supply shock would cause the FE line to
shift to the left.
Describe what happens to the FE line if government purchases increase.
In the classical model of the labor market, the rise in government purchases reduces people’s perceived wealth, so they increase their labor supply. The increase in labor supply results in a new labor market equilibrium with increased employment and a lower real wage. The higher level of employment shifts the FE line to the right.
The IS curve shows the combinations of output and the real interest rate for which
the goods market is in equilibrium.
The IS curve
slopes downward.
Any change that reduces desired saving relative to desired investment (for a given level of output) causes the real interest rate to ________ and shifts the IS curve ________.
increase; up and to the right
A decline in expected future output would cause the IS curve to
shift down and to the left.
A decrease in the effective tax rate on capital would cause the IS curve to
shift up and to the right.
An increase in labor supply would cause the IS curve to
remain unchanged.
An increase in the money supply would cause the IS curve to
remain unchanged.
A temporary decline in productivity would cause the IS curve to
remain unchanged.
A decrease in wealth would cause the IS curve to
shift down and to the left.
An increase in the expected future marginal product of capital would cause the IS curve to
shift up and to the right.
The IS curve would unambiguously shift up and to the right if there were
an increase in both government purchases and the expected future marginal product of capital.
Draw a saving-investment diagram to show how each of the following changes shifts the IS curve.
(a) Future income rises.
(b) The future marginal productivity of capital increases.
(c) Government purchases decrease temporarily.
(d) The effective corporate tax rate increases.
(a) Future income rises.
(b) The future marginal productivity of capital increases.

(d) IS shifts down and to the left.
A rise in the price of a bond causes the yield of the bond to
fall
A decline in the price of a bond causes the yield of the bond to
rise
The LM curve
slopes upward.
Looking only at the asset market, an increase in output would cause
an increase in the real interest rate along the LM curve.
A change that increases the real money supply relative to real money demand causes
the LM curve to shift down and to the right.
A change that increases real money demand relative to the real money supply causes
the LM curve to shift up and to the left.
Banks decide to raise the interest rate they pay on checking accounts from 1% to 2%. This action would
increase money demand, shifting the LM curve up and to the left.
You have just read that the Federal Reserve has increased the money supply to avoid a recession. For a given price level, you would expect the LM curve to
shift down and to the right as the real money supply rises.
The Fed has announced that it plans to lower the rate of monetary growth from 10% per year to 2% per year. You would expect this announcement to directly
increase money demand, shifting the LM curve up and to the left.
The probable effect of introducing an increased number of automatic teller machines is to
decrease money demand, shifting the LM curve down and to the right.
An increase in wealth that doesn’t affect labor supply would cause the IS curve to ________ and the FE line to ________.
shift up and to the right; be unchanged
An increase in the effective tax rate on capital would cause the IS curve to ________ and the LM curve to ________.
shift down and to the left; be unchanged
When all markets in the economy are simultaneously in equilibrium, we say
there is general equilibrium.
To reach general equilibrium, the price level adjusts to shift the ________ until it intersects with the ________.
LM curve; FE line and IS curve
What adjusts to restore general equilibrium after a shock to the economy?
The LM curve
The IS-LM model predicts that a temporary beneficial supply shock
increases output, national saving, and investment, but not the real interest rate.
A temporary supply shock, such as a bumper crop, would
shift the FE line to the right and leave the IS curve unchanged.
A temporary supply shock, such as an increase in oil prices, would
have no effect on the IS curve.
You have just read that Australia has suffered a drought, destroying its wheat crop for this year. The effect of this adverse supply shock on Australia would probably be
an increase in prices and an increase in real interest rates.
A temporary adverse supply shock directly causes
a shift to the left of the FE line.
After a temporary beneficial supply shock hits the economy, general equilibrium is restored by
a shift down and to the right of the LM curve.
An adverse supply shock that is permanent shifts which curve in addition to the curves shifted by one that is temporary?
The IS curve
Which market adjusts the quickest in response to shocks to the economy?
The asset market
A temporary decrease in government purchases causes the real interest rate to ________ and output to ________ in the short run, before prices adjust to restore equilibrium.
fall; fall
An increase in expected inflation causes the real interest rate to ________ and output to ________ in the short run, before prices adjust to restore equilibrium.
fall; rise
Suppose the intersection of the IS and LM curves is to the left of the FE line. A decrease in the price level would most likely eliminate a disequilibrium among the asset, labor, and goods markets by
shifting the LM curve down and to the right.
Suppose the intersection of the IS and LM curves is to the left of the FE line. What would most likely eliminate a disequilibrium among the asset, labor, and goods markets?
A fall in the price level, shifting the LM curve down and to the right

Classical economists think general equilibrium is attained relatively quickly because
the price level adjusts quickly.
Keynesian economists think general equilibrium is not attained quickly because
the price level adjusts slowly.
Keynesian economists believe that in the short run,
money neutrality does not exist and prices do not adjust rapidly.
Classical economists believe that in the short run,
money neutrality exists and prices adjust rapidly.
Under monetary neutrality, an increase in the money supply causes output to ________ and the price level to ________.
not change; rise
Under an assumption of monetary neutrality, a change in the nominal money supply has
a proportionate effect on the price level.
Describe the differences between classical and Keynesian economists in terms of their views about monetary neutrality.
Keynesians believe that monetary neutrality holds in the long run but not in the short run. Classical economists are more accepting of the view that money is neutral even in the relatively short run.
