1. List the three different types of unemployment and briefly discuss their respective causes.
Structural unemployment, caused by changes in the underlying structure of the economy. Frictional
unemployment, caused by short-run job/skill matching problems between workers and firms. Cyclical
unemployment, caused by the business cycle such that there is higher unemployment during recessions
and depressions.

2. Suppose an economy produced only automobiles and bicycles. Illustrate graphically how an
improved automobile technology would affect the production possibility frontier (PPF). Is it
true that all points on the frontier are efficient? Why or why not?
Automobiles
A
B
Bicycles
All points on the frontier, such as point A above, are efficient by definition of the PPF. The only
inefficient points are those that are strictly below the frontier, such as point B.
3. Suppose the goods market is in disequilibrium, such that planned aggregate expenditures are
greater than aggregate output. Briefly describe how this market would reach equilibrium, and
whether aggregate output would increase or decrease in equilibrium. Draw a graph illustrating
this situation.
When planned aggregate expenditures exceed aggregate output, planned investment does not equal
actual investment, resulting in a decrease in unplanned inventories. Firms respond to this decrease by
increasing production in subsequent production periods until planned aggregate expenditures equal
aggregate output. Thus, aggregate output increases in equilibrium. Graphically:

period:
Good A

$400
Find real GDP for this economy in each year if the base year is year 2 and a fixed-weight
procedure is used.
If year 2 is the base year, real GDP for good A in year 1 is $200 and real GDP for good B in year 1 is
$700. Therefore, real GDP for the economy in year 1 is $200 + $700 = $900. In year 2, real GDP is
$400 for both goods A and B. Therefore, real GDP for the economy in year 2 is $800.
5. Suppose the money market is in equilibrium. Discuss and illustrate graphically how a
contractionary monetary policy would affect the quantity of money supplied and demanded, as
well as the equilibrium interest rate.

We have MS ↓ → r ↑ → I ↓ → Y ↓ → Md ↓ → r ↓. Therefore, the money supply curve would shift to the
left, decreasing the quantity of money supplied and demanded, and increasing the interest rate.
Secondarily, the money demand curve would shift to the left, decreasing the interest rate by an amount
smaller in absolute value than the initial increase. Thus, the quantity of money supplied and demanded
would decrease (from M0 to M1), and the equilibrium interest rate would increase (from r0 to r2).

1. Read the following excerpt from an article that appeared on Bloomberg.com on March 3, 2008:
Australia to Raise Interest Rate to 12-Year High, Survey Shows
“Australia's central bank will probably increase interest rates to a 12-year high to cool an
economic expansion stoking the fastest inflation in almost two decades. Governor Glenn Stevens
will raise the overnight cash rate target by a quarter point to 7.25 percent, adding to last month's
increase, according to all 27 economists surveyed by Bloomberg News. Accelerating inflation,
stoked by a shortage of skilled workers and rising fuel prices, is forcing Stevens to raise rates as
counterparts in the U.S. and the U.K. signal cuts to cushion their economies from slower
growth.”
1.1 Describe the three main functions of the U.S. central bank. (1 point)
The three main functions of the U.S. central bank (the Federal Reserve) are to: 1) control the money
supply through open market operations, the required reserve requirement, and the discount rate; 2) serve
as a lender of last resort for commercial banks; and 3) to clear interbank payments.
1.2 According to the article, what are some of the reasons why Australia’s central bank may increase
interest rates? (1 point)
Australia’s central bank may increase interest rates to slow an economic expansion in that country. The
economic expansion is producing inflation due to skilled worker shortages and rising fuel prices.
1.3 Illustrate graphically how the action by the Australian central bank described in the article above will
affect the money market, the goods market, and the level of planned investment in Australia. (3 points)

2. Read the following excerpt from an article which appeared in the Economist on February 28, 2008:
Russia’s Economy: Smoke and Mirrors
“Productivity remains far below that of most developed countries. In the first years after the 1998
crisis, labour and capital efficiency went up by 5.8% a year. But that growth was driven by using
spare capacity left from Soviet times. Sustaining it will require more investment. Meanwhile the
economy, unable to digest the money generated by the oil-and-gas boom, is clearly overheating.
Inflation moved into double digits in late 2007, pushed up by, among other things, a huge inflow
of capital attracted by swelling reserves and the strong rouble. Unlike oil revenues, which can be
partially channelled into the stabilisation fund, this money cannot easily be absorbed.”
2.1 Define inflation and deflation. (1 point)
Inflation (deflation) is an increase (decrease) in the overall price level.
2.2 If the Russian economy continues to experience the inflationary changes suggested by the article,
what would happen to the demand for money balances in Russia? Why would this occur? (1 point)
We would expect the demand for money balances to increase. This occurs because the value of economic
transactions increases with increases in the price level, and therefore more money is needed to conduct
these transactions. If the central bank does nothing to change the money supply, there will be an increase
in interest rates.
2.3 What policy options does the central bank have in this situation, and what would be the result of
each? (1 point)
1) They can increase the money supply, which will reduce the tendency of interest rates to rise and will
induce further expansion of the economy; 2) they can do nothing and accept the higher interest rates; 3)
they can decrease the money supply, increasing interest rates still further and slowing the economy down.

2.4 Suppose the Russian economy experiences an increase in planned investment of $20 billion in an
effort to sustain the current growth rate. By how much will the equilibrium level of output change
if we assume that the goods market is independent of the money market and the MPC is 0.80?
(2 points)
The equilibrium level of output would increase by ($20 billion)*(1/(1 – 0.80) = $100 billion. Since we
are assuming the goods market is independent of the money market, we can ignore secondary effects.
