1. Suppose firm A’s stock is current sold at $30 per share in the market 23. After careful
analysis, you have determined that a firm’s dividends should grow at 7%, on average, in
the foreseeable future. The firm’s last dividend was $3. If your required return is 18%, is
firm A’s stock a good investment?
𝑃0 = $3 ×
1.07
= $29.18
−0.18 − 0.07
It is not a good investment as the stock is worth less than its current price, $29.18 which is $ 30.
2. Can a person with rational expectations expect the price of a share of Google to rise by
10% in the next month?
No, if the person similar information to the rest of the market. An expected price increase by10%
over the next month implies over a 100% annual return on Google stock, which certainly exceeds
its equilibrium return. This would mean that there is an unexploited profit opportunity in the
market, which would have been eliminated in an efficient market. The only time that the
person’s expectations could be rational is if the person had information unavailable to the market
that allowed him or her to beat the market.
3. Angus Bank holds no excess reserves but complies with the reserve requirement. The
required reserves ratio is 9%, and reserves are currently $27 million. Determine the
amount of deposits, the reserve shortage created by a deposit outflow of $5 million, and the
cost of the reserve shortage if Angus Bank borrows in the federal funds market (assume the
federal funds rate is 0.25%).
Deposits = 27/0.09 = 300. The reserve shortage is calculated as outstanding reserves after the
deposit outflow, minus required reserves after the deposit outflow:
22 ‒ 295 × 0.09 = ‒ 4.55
Angus Bank has to borrow $4.55 million. Borrowing from the Fed will cost Angus Bank:
0.0025 × 4.5 = $11,250 dollars.
4. Suppose you are the manager of a bank whose $100 billion of assets have an average
duration of four years and whose $90 billion of liabilities have an average duration of six
years. Conduct a duration analysis for the bank and show what will happen to the net
worth of the bank if interest rates rise by 2 percentage points.
The assets decrease by $8 million = $100 million× –2% ×4 years while liabilities decrease by
$10.8 million (= $90 million × –2% × 6 years. Given that the liabilities’ decrease in value is
more than the decrease n the value of assets by $2.8 million, the bank’s net worth rises by the
same value.
5. If the Fed lends five banks a total of $100 million but depositors withdraw $50 million
and hold it as currency, what happens to reserves and the monetary base? Use T-accounts
to explain your answer.

6. Suppose that currency in circulation is $600 billion, the amount of checkable deposits is $900
billion, and excess reserves are $15 billion.
a. Calculate the money supply, the currency deposit ratio, the excess reserve ratio, and the
money multiplier.
The money supply M = C + D = $600 billion + $900 billion = $1,500 billion;
c = C/D = 600/900 = 0.667;
e = ER/D = 15/900 = 0.017;
m = (1 + c)/(rr + e + c) = (1+0.667)/(0.1+0.017+0.667) = 1.667/0.783 = 2.13.
b. Suppose the central bank conducts an unusually large open market purchase of bonds
held by banks of $1,400 billion due to a sharp contraction in the economy. Assuming the
ratios you calculated in part (a) remain the same, predict the effect on the money supply.
The monetary base will decrease to $800 + $80 + $18 - $30 = $868 billion. Based on the money
multiplier calculated previously, this implies the money supply should decrease to $868 * 1.94 =
$ 1683.92 billion
c. Suppose the central bank conducts the same open market purchase as in part (b), except
that banks choose to hold all of these proceeds as excess reserves rather than loan them out,
due to fear of a financial crisis. Assuming that currency and deposits remain the same,
what happens to the amount of excess reserves, the excess reserve ratio, the money supply,
and the money multiplier?
ER = $1415 billion;
e = $1415/$900 = 1.57;
m = (1 + 0.667)/(0.1 + 1.57 + 0.667) = 0.71.
The money supply is remains at $1,500 billion, since the currency and deposits are the same.
7. Using the supply and demand analysis of the market for reserves, indicate what happens to the
federal funds rate, borrowed reserves, and nonborrowed reserves, holding everything else
constant, under the following situations.
a. The Fed raises the target federal funds rate.
To raise the target fed funds rate, the Fed will have to conduct an open market sale of securities,
which will shift the supply of nonborrowed reserves to the left. The fed funds rate will increase,
and as long as the equilibrium fed funds rate remains below the discount rate, borrowed reserves
will remain the same.

b. The Fed reduces reserve requirements and then offsets this action by conducting an open
market sale of securities.
With the decrease in required reserves, this reduces reserve demand as shown in part (e) above.
This will decrease the equilibrium fed funds rate. In order to sterilize the effects and keep the fed
funds rate unchanged, the Fed will conduct an open market sale of securities, shifting the reserve
supply line to the left. The end result is that the fed funds rate and borrowed reserves will be
unchanged, and nonborrowed reserves will decrease.

8. If the Fed has an interest rate target, why will an increase in the demand for reserves
lead to a rise in the money supply? Use a graph of the market for reserves to explain.
An increase in the demand for reserves will raise the federal funds rate. In order to maintain the
interest rate target, the Fed will buy bonds, thereby increasing the amount of nonborrowed
reserves, which shifts the supply curve for reserves to the right, thereby keeping the fed funds
rate from rising, as shown below. The open market purchase will then cause the monetary base
and the money supply to rise.

9. What does the Taylor rule imply that policymakers should do to the fed funds rate under the
following scenarios?
a. Unemployment rises due to a recession.
If unemployment rises, this would lower the output gap, and trigger a lower fed funds rate
according to the Taylor rule.
b. An oil price shock causes the inflation rate to rise by 1% and output to fall by 1%.
If inflation rises by 1%, this alone would prompt the fed funds rate to rise by 1.5 percentage
points. The decrease in the output gap alone would imply the fed funds rate would fall by 0.5
percentage points. Thus, the two factors together imply a net effect of increasing the fed funds
rate by one percentage point according to the Taylor rule.
c. The economy experiences prolonged increases in productivity growth while actual output
growth is unchanged.
Longer increases in productivity growth would increase potential output, and with the same rate
of actual output growth this would cause the output gap to decline, resulting in a decline in the
fed funds rate according to the Taylor rule.
