2Objectives
- Explain inside and outside lags for monetary and
fiscal policy. - Define the crowding-out and the Barro-Ricardo
effect. - Explain the effects of crowding-out within the
short-run AD and AS model. - Explain how the Barro-Ricardo effect can reduce
the crowing-out effect while simultaneously
reducing the effects of the fiscal policy. - Demonstrate the use of monetary policy to lessen
or reinforce the crowding-out effect.
3Introduction
- This lesson discusses the lags associated with
monetary and fiscal policy making and analyzes
the direct and indirect effects of government
budget deficits. - The direct effect of these deficits is an
increase in interest rates. - When the government borrows money to finance its
deficit, this results in an increase in the
demand for money, or, alternatively, the demand
for loanable funds. This in turn results in an
increase in the interest rate.
4- A higher interest rate causes decreases in
investment and other interest sensitive
components of AD. - Crowding-out is the decrease in private demand
for funds that occurs when the governments
demand for funds causes the interest rate to
rise - The demand by government for loanable funds
decreases or crowds-out the private demand for
loanable funds.
5Lags Associated With Policy Making
- The inside lag consists of the time it takes for
data to be collected, policy makers to recognize
that policy action is necessary, the decision
about which policy should be taken and the
implementation of the policy. - The outside lag is the time it takes the economy
to respond to the new policy. These lags differ
in length for monetary policy and fiscal policy.
6Activity 43 Monetary and Fiscal Policy
- Part A Tools of Monetary and Fiscal Policy
- Both monetary and fiscal policy can be used to
influence the inflation rate and real output.
Indicate what effect each specific policy has on
inflation and real output in the short-run (9 to
18 months).

9Part B Lags in Policy Making
- As the economic situation changes, policy makers
must decide when to take action and what policy
action to take. Then they must implement the
policy. - The economy then responds to the policy. The
amount of time it takes policy makers to
recognize and take action is called inside-lags. - The amount of time it takes the economy to
respond to the policy changes is called outside
or impact lags.
10- The inside lag is estimated to be short for
monetary policy, but long for fiscal policy. - The inside lag is long for fiscal policy because
the legislative branch must come to agreement
about the appropriate action. - The outside lag, however, is long and variable
for monetary policy but very short for the fiscal
policy.
11- Explain why the inside lag can be short for
monetary policy, but the outside lag is long and
variable.
The Federal Reserve can change the money supply
on a daily basis through open market operations.
Thus, once the Open Market Committee decides on a
particular policy, the policy can be implemented
immediately. However, monetary policy works
through changes in interest rates and the
response of interest-sensitive components of AD
to the interest rate changes. The response of
investment and consumption takes time.
12- Explain why the outside lag is short for fiscal
policy.
The outside lag is short for fiscal policy for
several reasons (1) Fiscal policy has been
debated in Congress and discussed extensively in
the media. Thus, as soon as it is enacted,
people can respond. (2) If the fiscal policy is a
tax change, the effects will be within a years
time. (3) If the fiscal policy is an expenditure
change, the effect will be felt almost
immediately as the affected agency changes its
spending pattern.
13- Explain why lags are important to the discussion
of stabilization policy.
The existence of policy lags implies that policy
actions could be out of sequence with the
economy. For example, expansionary policy might
have its impact after the economy has started to
recover from a recession. As a result, the
expansionary policy may create inflation because
it over stimulates the economy. This problem has
led some economies to recommend policy
rules. Examples of policy rules are that money
supply should grow at 5 a year and nominal GDP
should grow at 6 a year. Theres a second
reason why understanding lags is important for
stabilization policy. Policy makers should not
think that policy can fine-tune the economy at
any point in time.

- Given the change in interest rates, what happens
in the short-run AS and AD graph?
AD shifts back to AD2 because the increase in
interest rates reduces some private domestic
investment and interest-sensitive consumer
spending. This is crowding-out.

- How could a monetary policy action prevent the
changes in interest rates and output you
identified in (B) and (C)? Shift a curve in the
money market graph, and explain how this shift
would reduce crowding-out.
Shift the money supply curve to MS1. If the
money supply is increased to MS1, interest rates
would move back to i. If interest rates are at
i, there would be no crowding-out (or reduction)
of investment spending, and the AD would be AD1.
21Loanable Funds Market
Note The original demand curve is for the
private sector ONLY. At the beginning there is
no borrowing or debt by the federal government.
The increase in government demand for funds
crowds-out private investment.

- I2 is the quantity of loanable funds demanded by
the new equilibrium because at i1 (the
equilibrium interest rate), I2 is the quantity of
investment funds the private sector demands, as
shown by the private-sector demand curve.
23Barro-Ricardo Effect
- According to Barro-Ricardo effect budget deficit
has no effect on the real interest rate or
investment. This means that financing government
purchases by taxes or by borrowing is equivalent.

24Barro-Ricardo Effect
- The supply curve for funds will shift rightward.
The rightward shift in the supply curve reduces
the increase in the interest rate and reduces the
decrease in the private sector demand for funds.
Thus, the crowding-out effect is reduced if there
is a Barro-Ricardo effect.

26Part B Using the Loanable Funds Market
- The loanable funds market provides another
approach to looking at the effects of increases
in the budget deficit. - The demand for funds in the loanable funds
market comes from the private sector (business
investment and consumer borrowing), the
government sector (budget deficits) and the
foreign sector. - The supply of funds in the loanable funds market
comes from private savings (businesses and
households), the government sector (budget
surpluses), the Federal Reserve (money supply)
and the foreign sector.

- Shift one of the curves on Fig 44.2 to indicate
what occurs in the loanable funds market if
government spending increases without any
increases in tax revenue or the money supply.
The demand increases, shifting the demand curve
to D1. D1 represents the private plus public
demand for loanable funds.

There is an increase in the demand for loanable
funds to pay for the increased government
spending. The interest rate rises to i1

Q
- C. An accommodating monetary policy could
prevent the effects you described in (A) and (B).
Shift a curve in the diagram to show how the
accommodating monetary policy would counteract
the effects of crowding-out. Explain what would
happen to interest rates and the level of private
demand for loanable funds as a result of this new
curve.
If the monetary authorities expanded the money
supply to keep interest rates constant at the
original level, a larger quantity of loanable
funds would be available, and there would be no
crowding-out. The new supply curve in S1,
interest rates return to i and the private sector
receives the original level of loanable funds.
31Part C Applications
- Indicate whether you agree (A), disagree (D) or
are uncertain (U) about the truth of the
following statement and explain your reasoning.
Exhaustion of excess bank reserves inevitably
puts a ceiling on every business boom because
without money the boom cannot continue.
Uncertain. The answer should depend on the
assumptions that are made. The boom could
continue to grow if the velocity of circulation
increases. Increased demand for a fixed money
stock would tend to increase interest rates, and
increased velocity is associated with higher
interest rates. However, the higher interest
rates could cause investment to decrease and slow
economic growth.
32- Answer the questions that follow each of the
scenarios below. - The Federal Reserve Open Market Committee wishes
to accommodate or reinforce a contractionary
fiscal policy. - Would the Fed buy bonds, sell bonds or neither?
- What effect would this policy have on bond prices
and interest rates?
Sell bonds.
Bond prices would decrease, and the interest rate
would increase.
33- What effect would this policy have on bank
reserves and the money supply? - What effect would this policy have on the
quantity of loanable funds demanded by the
private sector?
Bank reserves would decrease, and the money
supply would decrease.
The bond sale would decrease the supply of
loanable funds the increase in the interest rate
would decrease the quantity demanded of loanable
funds (movement along the demand curve).
34- What effect would the change in interest rates
you identified in (B) have on aggregate demand?
AD would decrease because the higher interest
rates would curtail the interest-sensitive
components of consumption and investment.
35- The Federal Reserve Open Market Committee wishes
to accommodate or reinforce an expansionary
fiscal policy. - Would the Fed buy bonds, sell bonds or neither?
- What effect would this policy have on bond prices
and interest rates?
Buy bonds.
The price of bonds would increase, and the
interest rate would decrease.
36- What effect would this policy have on bank
reserves and the money supply? - What effect would this policy have on the
quantity of loanable funds demanded by the
private sector?
Bank Reserves would increase and the money supply
would increase.
The quantity demanded of loanable funds would
increase.
37- What effect would the change in interest rates
you identified in (B) have on AD?
AD would increase because of the lower interest
rates and the resulting increase in
interest-sensitive components of consumption and
investment.
