,Section A - Measuring GDP AND National Income
Q1.
In a closed economy, if the marginal propensity to consume is 0.8, and the government
increases spending by $100 billion while simultaneously raising taxes by $100 billion,
what is the net change in equilibrium GDP?
A. Increase by $100 billion B. Increase by $500 billion
C. No change D. Increase by $20 billion
Correct: A - Increase by $100 billion
Rationale:The balanced budget multiplier is 1. The spending multiplier is 5 (1/(1-0.8)=5), and
the tax multiplier is -4 (-MPC/(1-MPC)). The net effect is 5*100 + (-4)*100 = 100. Thus, GDP
increases by $100 billion.
Q2.
According to the Phillips curve, if the natural rate of unemployment is 5% and the current
unemployment rate is 3%, what must be the relationship between actual and expected
inflation if the economy is experiencing stagflation?
A. Actual inflation equals expected inflation B. Actual inflation is less than expected
inflation
C. Actual inflation is greater than expected D. Actual inflation is zero
inflation
Correct: C - Actual inflation is greater than expected inflation
Rationale:Stagflation combines high unemployment and high inflation. With unemployment
below the natural rate, the short-run Phillips curve suggests higher inflation. For stagflation,
actual inflation exceeds expected inflation, shifting the short-run curve upward.
Q3.
If the velocity of money is constant and real GDP grows at 3% per year, what is the
long-run inflation rate if the money supply grows at 7% per year?
A. 10% B. 4%
C. 3% D. 7%
Correct: B - 4%
Rationale:Using the quantity equation (MV=PY) in growth rates: %”M + %”V = %”P + %”Y.
With constant velocity (%V=0), %P = %M - %Y = 7% - 3% = 4%.

Q4.
Which of the following best explains why a country with a high savings rate may
experience slower economic growth in the long run?
A. Higher savings reduce aggregate B. Diminishing returns to capital eventually
demand, leading to recessions limit output per worker
C. Savers are less likely to invest in new D. High savings cause inflation, reducing
technology real returns
Correct: B - Diminishing returns to capital eventually limit output per worker
Rationale:In the Solow growth model, higher savings increase the steady-state capital per
worker, but due to diminishing returns, the marginal product of capital falls. Eventually, the
economy converges to a steady state with no further growth per capita.
Q5.
In an open economy with perfect capital mobility and a flexible exchange rate, an
expansionary fiscal policy will lead to:
A. An increase in output and a depreciation B. No change in output and an appreciation
of the currency of the currency
C. An increase in output and an appreciation D. No change in output and a depreciation
of the currency of the currency
Correct: C - An increase in output and an appreciation of the currency
Rationale:Under flexible exchange rates and perfect capital mobility, the Mundell-Fleming
model shows that fiscal expansion raises output and the interest rate, attracting capital
inflows, which appreciate the currency. The appreciation reduces net exports, partially
offsetting the output increase.
Q6.
If the central bank announces a new inflation target of 2% but the public does not believe
it, what is the most likely short-run effect on the Phillips curve?
A. The short-run Phillips curve shifts B. The short-run Phillips curve shifts upward
downward
C. The long-run Phillips curve shifts left D. No shift occurs
Correct: B - The short-run Phillips curve shifts upward
Rationale:If the public's expected inflation remains higher than the target, the short-run
Phillips curve shifts upward (higher inflation for any given unemployment rate). This reflects
the trade-off between credibility and inflation expectations.
