Macroeconomics Chp. 10, 11, 12
Changes in monetary policy shift the
LM curve.
In the Keynesian-cross model, fiscal policy has a multiplied effect on income because fiscal policy
changes income, which changes consumption, which further changes income.
In the IS-LM model, changes in taxes initially affect planned expenditures through
consumption.
An unexpected deflation can change demand by redistributing wealth from
debtors to creditors, thus lowering consumption.
According to the IS-LM model, if Congress raises taxes but the Fed wants to hold the interest rate constant, then the Fed must ______ the money supply
decrease
If a liquidity trap does exist, then ______ policy will not be effective in increasing income when interest rates reach very ______ levels
monetary; low
When drawn on a graph with income along the horizontal axis and the interest rate along the vertical axis, the IS curve generally
slopes downward and to the right.
Using the IS-LM analysis, if the LM curve is not horizontal, the multiplier for an increase in government spending is ______ for an increase in government purchases using the Keynesian-cross analysis
smaller than the multiplier
Equilibrium levels of income and interest rates are ______ related in the goods and services market, and equilibrium levels of income and interest rates are ______ related in the market for real money balances
negatively; positively
The IS-LM model is generally used
only in the short run.
A short-run aggregate supply curve shows fixed ______, and a long-run aggregate supply curve shows fixed ______
prices; output
According to the theory of liquidity preference, if the supply of real money balances exceeds the demand for real money balances, individuals will
purchase interest-earning assets in order to reduce holdings of non-interest-bearing money.
If expected inflation equals 3 percent and monetary policymakers push the nominal interest rate to 1 percent, the real interest rate equals ______ percent
-2
(Exhibit: Short Run to Long Run) Based on the graph, if the economy starts from a short-term equilibrium at A, then the long-run equilibrium will be at ____ with a _____ price level
B; lower
An increase in income raises money ______ and ______ the equilibrium interest rate
demand; raises
The short run refers to a period
during which prices are sticky and unemployment may occur.
If the Fed reduces the money supply by 5 percent and the quantity theory of money is true, then
every point on the aggregate demand curve moves 5 percent to the left.
(Exhibit: Keynesian Cross) In this graph, if firms are producing at level Y1, then inventories will ______, inducing firms to ______ production
fall; increase
According to the quantity theory of money, if output is higher, ______ real balances are required, and for fixed M this means ______ P
higher; lower
Most economists believe that the classical dichotomy
holds approximately in the long run but not at all in the short run.
A 5 percent reduction in the money supply will, according to most economists, reduce prices 5 percent of what but
in the long run but lead to unemployment in the short run.
An explanation for the slope of the LM curve is that as
income rises, money demand rises, and a higher interest rate is required.
The version of Okun's law studied in Chapter 10 assumes that with no change in unemployment, real GDP normally grows by 3 percent over a year. If the unemployment rate fell by 1 percentage point over a year, Okun's law predicts that real GDP would
increase by 5 percent.
In the IS-LM model under the usual conditions in a closed economy, an increase in government spending increases the interest rate and crowds out
investment.
The monetary transmission mechanism works through the effects of changes in the money supply on
investment.
According to the theory of liquidity preference, the supply of real money balances
is fixed.
If the Fed accommodates an adverse supply shock, output falls ______ and prices rise ______
less; more
If Congress passed a tax increase at the request of the president to reduce the budget deficit, but the Fed held the money supply constant, then the two policies together would generally lead to ______ income and a ______ interest rate
lower; lower
The IS curve plots the relationship between the interest rate and ______ that arises in the market for ______
national income; goods and services
The aggregate demand curve is the ______ relationship between the quantity of output demanded and the ______
negative; price level
Okun's law is the ______ relationship between real GDP and the ______
negative; unemployment rate
If the short-run aggregate supply curve is horizontal and the Fed increases the money supply, then
output and employment will increase in the short run.
Starting from long-run equilibrium, if the velocity of money increases (due to, for example, the invention of automatic teller machines) and no action is taken by the government
output will rise in the short run and prices will rise in the long run.

r2, Y3
(Exhibit: IS-LM Fiscal Policy) Based on the graph, starting from equilibrium at interest rate r1 and income Y1, a decrease in government spending would generate the new equilibrium combination of interest rate and income:
r3, Y2

raises; and may also lower
Monetary neutrality, the irrelevance of the money supply in determining values of _____ variables, is generally thought to be a property of the economy in the long run
real
An increase in the interest rate
reduces planned investment, because the interest rate is the cost of borrowing to finance investment projects.
Stabilization policy refers to policy actions aimed at
reducing the severity of short-run economic fluctuations.
When bond traders for the Federal Reserve seek to increase interest rates, they ______ bonds, which shifts the ______ curve to the left
sell; LM
Long-run growth in real GDP is determined primarily by ______, while short-run movements in real GDP are associated with ______
technological progress; variations in labor-market utilization
A supply shock does not occur when
the Fed increases the money supply.
Possible explanations put forth for the Great Depression do not include
the Pigou effect.
The interaction of the IS curve and the LM curve together determine
the equilibrium level of the interest rate and output.
The natural level of output is
the level of output at which the unemployment rate is at its natural level.
The vertical long-run aggregate supply curve satisfies the classical dichotomy because the natural rate of output does not depend on
the money supply.
The aggregate demand curve generally slopes downward and to the right because, for any given money supply M a higher price level P causes a ______ real money supply M/P, which ______ the interest rate and ______ spending
lower; raises; reduces
A movement along an aggregate demand curve corresponds to a change in income in the IS-LM model ______, while a shift in an aggregate demand curve corresponds to a change in income in the IS-LM model ______
resulting from a change in the price level; at a given price level
The relationship between the quantity of goods and services supplied and the price level is called
aggregate supply.
An increase in investment demand for any given level of income and interest rates—due, for example, to more optimistic "animal spirits"—will, within the IS-LM framework, ______ output and ______ interest rates
increase; raise
The IS and LM curves together generally determine
both income and the interest rate.
Business cycles are
irregular and unpredictable.

this represents a movement down the aggregate demand curve.

400.

investment rises but consumption falls.
Over the business cycle, investment spending ______ consumption spending

When firms experience unplanned inventory accumulation, they typically
lay off workers and reduce production.
The spending hypothesis suggests that the Great Depression was caused by a
leftward shift in the IS curve.
John Maynard Keynes wrote that responsibility for low income and high unemployment in economic downturns should be placed on
low aggregate demand.
The theory of liquidity preference implies that, other things being equal, an increase in the real money supply will
lower the interest rate.
