A Swiss watchmaker opens a factory in the US. This in an example of Swiss
foreign direct investment
If Germany purchased more abroad than it sold abroad last year, then it had
negative net exports which is a trade deficit
An open economy’s GDP is always given by

If the exchange rate is 125 yen = $1, a bottle of rice wine that costs 2500 yen costs

Which part of real GDP fluctuate most over the course of the business cycle?
Which of the following explains why productions rises in most years
Aggregate demand shifts left when the government
cuts military expenditures (when G goes down)
The aggregate quantity of goods and services demanded changes as the price level falls because
real wealth rises, interest rates fall, and the dollar depreciates
Which of the following is not a determinant of the long-run level of GDP?
the price level
The long run aggregate supply curve shifts right if
All of the above
The variables on the vertical and horizontal axes of the AD and AS graph are
the price level (P) and real output (Y)
AS curve is upward sloping in
the short run, not the long run
refer to graph 33-1) If the economy starts at C, an increase in the money supply moves the economy
to A in the long run (up the vertical line)
(grap 33-1) If the economy is at A and there is a fall in AD curve, in the short run the economy
moves to D
According to liquidity preference theory, the money-supply curve would shift rightward
if the Federal Reserve chose to increase money supply
When the interest rate increases, the opportunity cost of holding money
increases, so the quantity of money demanded decreases
Which of the following events would shift the money demand to the right?
an increase in the price level, but not an increase in the interest rate
(figure 34-4) A shift of the money demand curve from MD2 to MD1 (shift down) is consistent with which of the following events?
The government reduces government spending, resulting in a decrease in people’s incomes
Assume MPC is .75. The multiplier is
If Congress cuts spending to balance the federal budget, the Fed can act to prevent unemployment and recession by
buying bonds to increase the money supply
What actions could be taken to stabilize output in response to a large decrease in US net exports?
increase government expenditure or increase money supply
Fiscal policy refers to the idea that AD is affected by changes in
government spending and taxes
The government buys new weapons systems. The manufacturers of weapons pay their employees. The employees spend this money on goods and services, the firm from which the employees ut the g and s pay their empliyees. this sequence of events illustrates
the multiplier effect
a decrease in government spending initialy and primarily shifts
AD to the left
According to the Phillips Curve, unemployment and inflation are inversely related in
the short run, but not the long run
Which of the following is correct concerning the long run Phillips curve
Its position depends on the natural rate of unemployment
(figure 35-4). If the economy starts at C and the money supply growth rate increases, then in the short run the economy moves to
An adverse supply sock causes inflation to
rise and the short run Phillips curve to shift right
Variables that Influence Net Exports
preferences for foreign and domestic goods
of goods at home and abroad
of consumers at home and abroad
exchange rates at which foreign currency trades for domestic currency
an excess of imports over exports
an excess of exports over imports
Net capital outflow (NCO):
residents’ purchases of foreign assets
foreigners’ purchases of domestic assets
NCO is also called net foreign investment
Foreign direct investment
residents actively manage the foreign investment, e.g.,
McDonalds opens a fast-food outlet in Moscow.
Foreign portfolio investment
residents purchase foreign stocks or bonds, supplying “loanable funds” to a
NCO = NX
Y = C + I + G + NX accounting identity
Y – C – G = I + NX rearranging
S = I + NX since S = Y – C – G
S = I + NCO
Real exchange rate
(e x P)/P*
P = domestic
P* = foreign
price (in foreign currency)
e = nominal exchange rate, i.e.,
currency per unit of domestic currency
theory of exchange rates whereby a unit of
any currency should be able to buy the same quantity of goods in all countries
of the following statements about a country with a trade deficit is not true?
A. Exports < imports
B. Net capital outflow < 0
C. Investment < saving
D. Y < C + I + G
separation of variables into two groups:
– quantities, relative prices
– measured in terms of money
increase in P reduces the quantity of g&s
event that changes C, I, G, or NX—except
a change in P—will shift the AD
A stock market boom makes households feel wealthier, C rises,
curve shifts right.
Why the AD Curve Might Shift
re: consumption/saving tradeoff
buy new computers, equipment, factories
rates, monetary policy
Tax Credit or other tax incentives
& local spending, e.g.,
in countries that buy our exports
resulting from international speculation in foreign exchange market
Why the LRAS
Curve Might Shift
in L or natural rate of unemployment
policies reduce natural u-rate
in K or H
in factories, equipment
people get college degrees
destroyed by a hurricane
in natural resources
of new mineral deposits
in supply of imported oil
weather patterns that affect agricultural production
improvements from technological progress

The variables that influence money demand
Y, r, and P
A. Suppose r rises, but Y and P are
unchanged. What happens to money demand?
B. Suppose P rises, but Y and r are
unchanged. What happens to money demand?
curve is vertical: Changes in r do not affect MS,
which is fixed by the Fed.
A fall in r increases money demand.
How the Interest-Rate Effect Works
A fall in P reduces money demand, which lowers r.
A fall in r increases I and
the quantity of g&s demanded
federal funds rate
which banks charge each other on
change the interest rate and
shift the AD
the Fed conducts open market operations
to change MS.
The Effects of Reducing the Money Supply
Fed can raise r by reducing the money supplyAn
increase in r reduces the quantity of g&s
policy stimulates aggregate demand by reducing the interest rate.
when the interest rate is zero
liquidity trap, mon. policy may not work, since nominal
interest rates cannot be reduced further.
central bank can make real interest rates negative by raising inflation
§Expansionary fiscal policy
increase in G and/or decrease in T
§Contractionary fiscal policy
decrease in G and/or increase in T
the additional shifts in AD
that result when fiscal policy increases income and thereby increases consumer
The Crowding-Out Effect
policy has another effect on AD
that works in the opposite direction.
fiscal expansion raises r,
which reduces investment,
which reduces the net increase in agg demand
Changes in Taxes
cut increases households’ take-home pay.
respond by spending a portion of this extra income, shifting AD to
size of the shift is affected by the multiplier and crowding-out effects.
factor: whether households perceive the
tax cut to be temporary or permanent.
permanent tax cut causes a bigger increase in C—and
a bigger shift in the AD
curve—than a temporary tax cut.
claim that unemployment eventually returns to its normal or “natural” rate,
regardless of the inflation rate
natural rate of unemp-(a(actual inflation -expected inflation))
How an Adverse Supply Shock Shifts the PC
SRAS shifts left, prices rise, output &
& u-rate both increase as the PC shifts upward.
reduction in the inflation rate
Fed must slow the rate of money growth,
which reduces agg demand.
Output falls and unemployment rises.
Output & unemployment return to their natural rates.
