Study Questions on Monetary Policy and Fiscal Policy

1. What is Monetary policy? What is the general strategy of monetary policy? Use an AS/AD graph to explain your answer.

2. What is Keynes’s Liquidity preference theory? According to this theory,what happens in the short-run when the supply of money exceeds the demand for money? …when supply of money is less than the demand for money?

3. Suppose there is an increase in the money supply. Using a graph show the impact this has on the real rate of interest in the SR. What happens to I and AD?

4. When the Fed describes its monetary policy actions, it usually does so in terms of an interest-rate target. Explain why an interest-rate target effectively amounts to a money supply target. Use a graph to explain your answer.

5. What is the federal funds rate?

6. What is Fiscal Policy? What is general strategy of fiscal policy?

7. What is the crowding-out effect? Provide a detailed explanation of the crowding-out effect.

8. What is the primary argument against active fiscal policy and monetary policy?

9. Explain what is meant by the term “automatic stabilizers”.

10. Multiple choice questions. Select the best answer.

10a. The crowding-out effect implies that an increase in G (holding taxes constant) would lead to all of the following EXCEPT:

  1. a decrease (leftward shift) in money demand.
  2. an increase in the real rate of interest.
  3. a decrease in investment spending.
  4. an offset to the initial increase in aggregate demand.
  5. it would lead to all of the above.

10b. The federal funds rate is:

  1. is the interest rate that the Fed charges banks for short-term loans.
  2. is the interest rate that banks charge each other for short-term loans of reserves.
  3. is the interest rate that banks charge their best corporate customers.
  4. is the interest rate that banks pay on savings accounts.
  5. None of the above.

10c. An example of an automatic stabilizer is:

  1. the President and Congress agree to new legislation that will cut taxes during a recession.
  2. the drop in income taxes that occurs during recessions from the general drop in incomes.
  3. the President and Congress agree to new legislation that will increase government spending during a recession.
  4. All of the above.
  5. None of the above.

10d. According to the AS/AD framework, if there is an unanticipated drop in consumer wealth and if policy makers wanted to avoid a drop in real output and employment, they should:

  1. increase government spending.
  2. cut taxes.
  3. increase the growth rate of the money supply.
  4. any of the above.
  5. none of the above.

10e. See graph below. The initial money supply and money demand are MS1 and MD1, respectively. Suppose the Fed expects money demand to increase in MD2. If the Fed desires to maintain the interest rate at r* it would have to , because if the Fed kept the money supply constant at MS1 the interest rate would .

  1. increase the money supply to MS2; fall.
  2. increase the money supply to MS2; rise.
  3. decrease the money supply to MS0; fall..
  4. decrease the money supply to MS0; rise.

ANSWERS

1. Monetary Policy refers to changes in the money supply that are designed to reduce fluctuations in output, employment and the price level.

The general strategy of monetary policy is to increase the growth rate of the money supply during periods of recessions (high unemployment and low output growth) and reduce the money supply growth rate during periods of high inflation.

For example, suppose there is unexpected decrease in consumer confidence. This would ordinarily lead to a drop in AD (see arrow 1)and consequently a decline in Y (a recession). However, if the Fed expands the money supply this will increase AD (see arrow 2) and thereby offset the initial decline in AD. There will therefore be no change in Y, or if Y has already started to fall it will dampen the decline and speed up recovery from the recession.

2. It claims that the interest rate adjusts to bring about equilibrium between money supply and money demand. If the supply of money exceeds the demand for money, then the public will attempt to reduce their excess holdings of money by buying bonds and/or depositing funds into banks. This will cause the real rate of interest to fall. As the interest rate falls, the opportunity cost of holding money declines. This in turn results in an increase in the demand for money (movement down along the MD curve) until money supply and money demand are again equal.

If the demand for money exceeds the supply of money, then the public will attempt to increase their holdings of money by selling bonds and/or withdrawing funds from banks. This will cause the real rate of interest to rise. As the interest rate increases, the opportunity cost of holding money rises. This in turn results in a decrease in the demand for money (movement up along the MD curve) until money supply and money demand are again equal.

At r1, MS>MD*. At r1, MS<MD*.

The interest rate is bid down to r2. The interest rate is bid up to r2.

The increase in the money supply will initially create an excess supply of money at r1 (that is, MS2 > MD1 at r1). The public reduces excess holdings of money by buying bonds

and/or depositing it in a deposit at the bank. This causes the real rate of interest to decline to r2. The lower interest rate means that the cost of borrowing is lower and this will cause investment spending (which if financed by borrowing) to rise. The increase in investment leads to an increase in aggregate demand (i.e., the AD curve shifts to the right).

4. Suppose the Fed desires to lower the interest rate to r* (so r* is the target interest rate).

To do so would require an increase in the money supply to MS2. In other words, to adopt a policy that lowers r is to adopt a policy that increases the money supply since the increase in the money supply is necessary to achieve the lower interest rate.

Suppose the Fed desires to raise the interest rate to r* (so r* is the target interest rate).

To do so would require a decrease in the money supply to MS2. In other words, to adopt a policy that raises r is to adopt a policy that decreases the money supply since the decrease in the money supply is necessary to achieve the higher interest rate. See graph below.

5. The federal funds rate is the interest rate that banks charge each other for short-term loans of reserves. In recent years, the Fed has conducted monetary policy by targeting this rate of interest.

6. Fiscal policy refers to the use of government spending (G) and/or taxes (T) by the government to reduce to fluctuations in such macro variables as real output and employment. The general strategy behind fiscal policy is to raise government spending and/or cut taxes during recessions. Either an increase in G or decrease in T will raise aggregate demand.

7. Crowding-out effect: the offset in aggregate demand that results when expansionary fiscal policy (increase G and/or cut in T) raises the interest rate and thereby reduces investment spending.

The (unanticipated) increase in G causes the AD curve to shift to right (to AD2 in the graph below). The increase in AD leads to an increase in P and Y. The increase in P and Y lead to higher money demand (MD shifts to MD2 in graph below) and this causes the interest rate to be bid up to r2. The higher interest rate leads to a drop in investment and a reduction in AD (the AD shifts back to the left-- AD3 in the graph). This reduction in AD partially offsets the initial increase in AD. Thus, fiscal policy has a smaller impact on real output and employment.

Summary: G↑  AD↑ to AD2 P and Y↑  MD↑ to MD2 r↑I↓ AD↓ to AD3 .

8. Monetary and fiscal policy affect the economy with a long lag.

For fiscal policy, before legislation can be passed the legislators must (a) agree or recognize that the economy is in a recession, (b)then they must agree on what type fiscal policy (spending increase? tax cut? Both? Which type of spending increase? which type of tax cut?), and (c) once the legislation is passed there is lag between the time G and/or T are changed and when these changes have an impact on the economy.

Monetary policy works by cutting interest rates to affect investment. But many firms make investment plans far in advance. Thus, investment spending is not immediately affected.

The lags imply that policy makers will generally act too late. In fact, these policies may make matters worse—that is, they may destabilize the economy since their effects may be felt when the problem they were designed to solve no longer exists.

9. During recessions income tax revenue falls as there is a general decline in incomes. Also, government spending programs like welfare and unemployment insurance increase as employment declines. Thus, without the passage of any new legislation government spending automatically rises and taxes automatically fall during recessions—hence the name “automatic stabilizers”.
