According to the neoclassical perspective, what mainly determines the level of real GDP in the long run?
The economy's productive capacity
✓
The level of consumer spending
The size of government budgets
The quantity of money in circulation
Correct Answer
The economy's productive capacity
The neoclassical perspective holds that long-run output is set by aggregate supply, meaning the economy's capacity to produce with its labor, capital and technology. The level of consumer spending is part of aggregate demand, which in this view moves output only in the short run. The size of government budgets also works through aggregate demand and so has no lasting effect on output in this model. The quantity of money in circulation affects the price level in the long run, not real output.

Question 2
Potential GDP is the level of output an economy produces when
Its unemployment rate reaches zero
All its resources are fully employed
✓
Aggregate demand is at its highest
Its price level stops changing
Correct Answer
All its resources are fully employed
Potential GDP is the output produced when land, labor, capital and entrepreneurial ability are all fully employed. Its unemployment rate reaches zero is wrong because frictional and structural unemployment remain even at full employment. Aggregate demand is at its highest is wrong because potential GDP is a supply-side measure of capacity, not a demand peak. Its price level stops changing is wrong because the economy can be at potential while prices are rising.

Question 3
When an economy is producing exactly at potential GDP, which type of unemployment is equal to zero?
Frictional unemployment
Structural unemployment
Cyclical unemployment
✓
Seasonal unemployment
Correct Answer
Cyclical unemployment
Cyclical unemployment comes from output falling below potential GDP, so it disappears when the economy is at potential. Frictional unemployment remains because people are always between jobs or entering the labor force. Structural unemployment remains because some workers' skills or locations do not match available jobs. Seasonal unemployment remains because some work, such as farm or resort work, rises and falls with the time of year.

Question 4
In the neoclassical model, which change would shift the long-run aggregate supply curve to the right?
An increase in government purchases
An increase in the money supply
A rise in consumer confidence
An increase in human capital per worker
✓
Correct Answer
An increase in human capital per worker
Long-run aggregate supply sits at potential GDP, and it moves right when productivity rises through more human capital, more physical capital per worker or better technology. An increase in government purchases shifts aggregate demand, not long-run supply. An increase in the money supply works through aggregate demand and in the long run raises only the price level. A rise in consumer confidence increases consumption and shifts aggregate demand.
Category: Potential GDP
Question 5
How does the neoclassical perspective view inflation?
As a cost that buys no lasting drop in unemployment
✓
As a price worth paying for lower unemployment
As a sign that output has reached a new high
As a problem only tax changes can control
Correct Answer
As a cost that buys no lasting drop in unemployment
Because the neoclassical model has no long-run tradeoff, inflation is seen as a cost with no offsetting long-run gain in employment. A price worth paying for lower unemployment describes the Keynesian view of the short-run tradeoff. A sign that output has reached a new high is wrong because, in this model, rising prices do not raise long-run output. A problem only tax changes can control is wrong because the neoclassical view treats aggregate demand in general, including monetary policy, as useful for controlling inflation.

Question 6
An economy is at potential GDP of 800 with a price level of 100. Aggregate demand increases, and in the short run real GDP rises to 840 and the price level to 104. According to the neoclassical model, what is real GDP in the long run once wages adjust?
840
800
✓
820
880
Correct Answer
800
In the neoclassical model, output above potential creates labor shortages, wages rise, and short-run aggregate supply shifts left until real GDP returns to potential, 800, at a higher price level. 840 is the short-run result before wages adjust. 820 assumes the economy keeps half of the short-run gain, which the model does not predict. 880 adds the short-run gain again instead of reversing it.
Category: Adjusting to Demand Shocks
Question 7
Starting from potential GDP, aggregate demand shifts to the right. What does the neoclassical model predict for the long run?
Higher output with the price level unchanged
Higher output and a higher price level
A higher price level with output unchanged
✓
Lower output and a lower price level
Correct Answer
A higher price level with output unchanged
With a vertical long-run aggregate supply curve, the extra demand ends up only raising the price level while real GDP returns to potential. Higher output with the price level unchanged would require a horizontal supply curve, which is not the long-run neoclassical case. Higher output and a higher price level describes the short-run result before wages adjust. Lower output and a lower price level is what a decrease in aggregate demand would cause in the short run.
Category: Adjusting to Demand Shocks
Question 8
After a positive demand shock pushes output above potential GDP, what causes the short-run aggregate supply curve to shift left in the neoclassical model?
Falling wages as workers compete for scarce jobs
Lower energy prices for producers
Faster growth in labor productivity
Rising wages as employers compete for scarce workers
✓
Correct Answer
Rising wages as employers compete for scarce workers
When unemployment is below its natural rate, firms bid up wages to attract scarce workers, which raises costs and shifts short-run aggregate supply left. Falling wages as workers compete for scarce jobs is what happens after a negative demand shock and would shift the curve right. Lower energy prices for producers reduce costs and would also shift the curve right. Faster growth in labor productivity lowers costs per unit of output and shifts supply to the right.
Category: Adjusting to Demand Shocks
Question 9
A fall in aggregate demand pushes output below potential GDP. According to the neoclassical model, how does the economy return to potential?
Wages and input prices fall, shifting short-run supply right
✓
Wages rise, shifting short-run supply left
Aggregate demand shifts back right on its own
Long-run supply shifts left to meet the lower output
Correct Answer
Wages and input prices fall, shifting short-run supply right
With unemployment above the natural rate, wages stagnate or fall, lowering costs so the short-run aggregate supply curve shifts right until output is back at potential at a lower price level. Wages rise, shifting short-run supply left would push output even further below potential. Aggregate demand shifts back right on its own is not the adjustment the model describes; the self-correction works through wages and prices. Long-run supply shifts left to meet the lower output is wrong because a demand shock does not change potential GDP.
Category: Adjusting to Demand Shocks
Question 10
According to neoclassical economists, how should aggregate demand grow over time?
Only during recessions
In line with the gradual growth of potential GDP
✓
Faster than potential GDP to lower unemployment
Whenever the inflation rate is falling
Correct Answer
In line with the gradual growth of potential GDP
Because demand has no long-run effect on output or unemployment in the neoclassical model, it should grow in step with the gradual rightward shift of long-run aggregate supply, which keeps the price level stable. Only during recessions reflects active stabilization, which neoclassical economists are skeptical of. Faster than potential GDP to lower unemployment would, in this model, produce inflation without lasting job gains. Whenever the inflation rate is falling ties demand to a short-run signal rather than to long-run capacity.

Question 11
A worker expects inflation next year to be about what it has been in recent years and revises that belief slowly as new data arrive. This behavior matches which idea?
Rational expectations
Say's law
Adaptive expectations
✓
The Phillips curve
Correct Answer
Adaptive expectations
Adaptive expectations describe people who look at past experience and gradually adjust their beliefs and behavior as circumstances change. Rational expectations would have the worker use all available information, including announced policy, to form the most accurate forecast possible. Say's law is the classical idea that supply creates its own demand. The Phillips curve is a relationship between inflation and unemployment, not a theory of how people form beliefs.
Category: Expectations
Question 12
Suppose firms and workers hold rational expectations and know that long-run aggregate supply is vertical. If an increase in aggregate demand is announced, what does this theory predict?
A long period of output above potential
A permanent fall in unemployment
A drop in the price level
A quick move to a higher price level with little change in output
✓
Correct Answer
A quick move to a higher price level with little change in output
People with rational expectations understand that a demand increase will raise the price level and only temporarily raise output, so they adjust wages and prices right away and skip the swing in hiring and output. A long period of output above potential is what slow adjustment would produce, not rational expectations. A permanent fall in unemployment cannot occur when long-run supply is vertical. A drop in the price level is the opposite of what higher demand causes.

Question 13
The months it takes for government statisticians to measure GDP and for policymakers to realize that a recession has started are called the
Recognition lag
✓
Implementation lag
Impact lag
Adjustment lag
Correct Answer
Recognition lag
The recognition lag is the delay before policymakers can see that the economy has turned, partly because preliminary GDP estimates take months and are later revised. The implementation lag is the time after a policy is passed for funds to reach agencies and programs to start, not the time to notice a downturn. The impact lag is the later delay while an enacted policy works its way into spending and production. Adjustment lag is not the name of a policy lag; the time wages and prices take to adjust is part of the economy's self-correction, not of policymaking.
Category: Policy Lags
Question 14
A proposed tax cut takes several months to be debated and passed by Congress. This delay is an example of the
Recognition lag
Legislative lag
✓
Implementation lag
Impact lag
Correct Answer
Legislative lag
The legislative lag is the time the political process needs to pass a tax or spending bill, which is what the months of debate in Congress represent. Recognition lag is the earlier delay in realizing that a recession has begun. Implementation lag comes after the bill passes, while funds reach the agencies and programs get started. Impact lag is the later delay while the change works its way into spending and output.
Category: Policy Lags
Question 15
Why do neoclassical economists argue that active stabilization policy can do harm?
It tends to lower the price level
It permanently shrinks potential GDP
It may take effect late and worsen economic swings
✓
It can only be used during expansions
Correct Answer
It may take effect late and worsen economic swings
Because it takes time to recognize a recession (the recognition lag), to pass a policy (the legislative lag) and for the policy to change spending and output, a policy aimed at a recession may arrive after recovery is underway and push an already expanding economy too far, making cycles worse. It tends to lower the price level is wrong because stimulus policy tends to raise prices. It permanently shrinks potential GDP is not the concern; the argument is about timing. It can only be used during expansions is wrong because stabilization policy is designed for both recessions and booms.
Category: Policy Lags
Question 16
In the neoclassical model, what shape does the long-run Phillips curve have?
Downward sloping across all unemployment rates
Horizontal at a zero inflation rate
Upward sloping as unemployment rises
Vertical at the natural rate of unemployment
✓
Correct Answer
Vertical at the natural rate of unemployment
With output fixed at potential in the long run, unemployment stays at its natural rate whatever the inflation rate, so the long-run Phillips curve is a vertical line. Downward sloping across all unemployment rates describes the short-run tradeoff, not the long run. Horizontal at a zero inflation rate would mean unemployment changes with no change in inflation, which the model does not predict. Upward sloping as unemployment rises is not a shape the neoclassical model gives.
Category: Phillips Curve
Question 17
An economy's unemployment rate fell to 3% while inflation rose, later rose to 7% in a recession while inflation fell, and each time returned to 5%. Using the neoclassical approach, what is the best estimate of its natural rate of unemployment?
5%
✓
3%
7%
0%
Correct Answer
5%
The natural rate is the rate the economy keeps returning to after demand shocks, which here is 5%. 3% is a temporary low reached when demand was strong and inflation was rising. 7% is a temporary high reached during a recession. 0% is wrong because frictional and structural unemployment keep the natural rate above zero.
Category: Phillips Curve
Question 18
A lender charges a nominal interest rate of 7% and expects inflation of 3% over the loan. What real interest rate does the lender expect to earn?
10%
4%
✓
3%
7%
Correct Answer
4%
The expected real interest rate equals the nominal rate minus expected inflation, so 7% minus 3% gives 4%. 10% adds expected inflation to the nominal rate instead of subtracting it. 3% is the expected inflation rate itself, not the real return. 7% is the nominal rate before any adjustment for inflation.
Category: Expectations
Question 19
The natural rate of unemployment is made up of which types of unemployment?
Cyclical and frictional
Cyclical and structural
Frictional and structural
✓
Seasonal and cyclical
Correct Answer
Frictional and structural
The natural rate is the unemployment that exists even at potential GDP, which is frictional plus structural unemployment. Cyclical and frictional is wrong because cyclical unemployment exists only when output is below potential. Cyclical and structural is wrong for the same reason. Seasonal and cyclical is wrong because it includes cyclical unemployment, which is zero at the natural rate.
Category: Unemployment Policy
Question 20
Which policy fits the neoclassical approach to lowering unemployment?
A large increase in government spending
A temporary cut in income taxes
Lower interest rates to boost borrowing
Retraining programs for structurally unemployed workers
✓
Correct Answer
Retraining programs for structurally unemployed workers
Neoclassical economists focus on lowering the natural rate of unemployment through labor market reforms such as retraining, better job information and worker mobility. A large increase in government spending raises aggregate demand, which in this view lowers unemployment only temporarily. A temporary cut in income taxes is also a demand-side tool with only a short-run effect in this model. Lower interest rates to boost borrowing work through aggregate demand as well and do not change the natural rate.
