Error Number 10
Question 1 (e)
Based on the real interest rate change in part (d), what
is the effect on the long-run economic growth rate?
(The real interest rate increased due to an increase in
government borrowing to finance spending.)
Decrease
Error Number 9
Question 1 (c)
If the marginal propensity to consume is equal to 0.75,
calculate the maximum possible change in real gross
domestic product that could result from the $100 billion
increase in government spending.
$400 billion
Error Number 8
Question 2 (a) (i)
Assume that the Federal Reserve targets a lower federal
funds rate. (i) Which open market operation can the
Federal Reserve use to achieve the lower target?
Buy Bonds
Error Number 7
Question 3 (b) (ii)
Based on the change in United States exports in part (a),
answer each of the following. (Exports Increased)
(i) Will the United States current account balance remain at zero, be in surplus,
or be in deficit?
(ii) What will happen to real gross domestic product in the
United States in the short run? Explain.
Increase because an increase in exports increases
aggregate demand.
Error Number 6
Question 3 (c)
The South Korean currency is the won. Draw a
correctly labeled graph of the foreign exchange market
for the United States dollar. Show the effect of the lower
inflation rate in the United States on the won price per
United Stated dollar.
There are two points. One for a proper graph and one
for showing the effect on the won price per US dollar.
This point is about the latter.
Error Number 6

D’ for $
D for $
Also correct is a decrease in supply, or both.
Q of $
Error Number 5
Question 1 (f)
Now assume that instead of financing the $100 billion
increase in government spending by borrowing, the
United States government increases taxes by $100
billion. With this equal increase in government spending
and taxes, will the real gross domestic product
increase, decrease, or remain the same? Explain.
Increase
Error Number 4
Question 2 (c)
Assume that the Federal Reserve buys government
bonds from commercial banks. Based only on this
transaction, will the level of required reserves in the
commercial banks increase, decrease, or remain the
same?
Remain the same
Error Number 3
Question 2 (d)
Another monetary policy action involves the discount
rate. Define the discount rate.
The discount rate is the interest rate charged by the
Federal Reserve to commercial banks for funds
borrowed from the Federal Reserve.
Error Number 2
Question 1 (f)
Now assume that instead of financing the $100 billion increase in
government spending by borrowing, the United States government
increases taxes by $100 billion. With this equal increase in
government spending and taxes, will the real gross domestic product
increase, decrease, or remain the same? Explain.
Real GDP increases because the multiplier for
government spending is larger than the multiplier
for taxes.
Error Number 1
Question 1 (e)
Based on the real interest rate change in part (d), what is the effect
on the long-run economic growth rate? Explain.
(The real interest rate increased due to an increase in
government borrowing to finance spending.)
The economic growth rate decreases because
a higher real interest rate reduces the
growth rate of the stock of capital.
