#1
What does the Phillips Curve describe?
The relationship between inflation and unemployment
ExplanationInflation and unemployment have an inverse relationship.
#2
In the short run, according to the Phillips Curve theory, what typically happens when unemployment decreases?
Inflation increases
ExplanationLower unemployment leads to higher inflation in the short run.
#3
What is the main criticism of the Phillips Curve?
It does not account for supply-side shocks
ExplanationIt overlooks external factors like supply-side shocks.
#4
According to the expectations-augmented Phillips Curve, what happens when workers and firms adjust their expectations of inflation?
The short-run Phillips Curve shifts upward
ExplanationAdjusting expectations can lead to a shift in the short-run Phillips Curve.
#5
What is the long-term implication of a country consistently operating below its potential GDP?
Decreased inflation
ExplanationConsistently operating below potential GDP results in lower inflation.
#6
Which policy instrument is primarily used to counteract high inflation?
Contractionary monetary policy
ExplanationContractionary monetary policy is used to combat high inflation.
#7
What is the primary assumption behind the Phillips Curve theory?
Constant level of inflation
ExplanationThe Phillips Curve theory assumes a constant level of inflation.
#8
How does the long-run Phillips Curve differ from the short-run Phillips Curve?
It is vertical
ExplanationThe long-run Phillips Curve is vertical.
#9
Which of the following represents a scenario where the Phillips Curve might not hold?
A period of stagflation
ExplanationStagflation challenges the assumptions of the Phillips Curve.
#10
What is the primary limitation of using the Phillips Curve for policy-making?
It assumes a constant relationship between inflation and unemployment
ExplanationThe Phillips Curve assumes a constant relationship between inflation and unemployment, limiting its applicability.
#11
What is the primary assumption of the short-run Phillips Curve?
Inflation and unemployment are inversely related
ExplanationThe short-run Phillips Curve assumes an inverse relationship between inflation and unemployment.
#12
Which of the following best explains the shape of the Phillips Curve?
It is quadratic
ExplanationThe Phillips Curve has a quadratic shape.
#13
Which economist is credited with introducing the concept of the Phillips Curve?
A.W. Phillips
ExplanationA.W. Phillips introduced the Phillips Curve.
#14
According to the natural rate hypothesis, what happens in the long run when unemployment falls below the natural rate?
Inflation increases
ExplanationBelow the natural rate, unemployment leads to inflation in the long run.
#15
What is the term used to describe the situation when policymakers face a trade-off between inflation and unemployment in the short run?
Stagflation
ExplanationPolicymakers face a trade-off between inflation and unemployment in the short run, termed as stagflation.
#16
Which of the following best describes the relationship between the Phillips Curve and the concept of potential output?
Potential output is the level of output where the Phillips Curve intersects with the natural rate of unemployment
ExplanationPotential output intersects with the natural rate of unemployment on the Phillips Curve.
#17
What is the main factor that could cause the Phillips Curve to shift to the right?
A decrease in aggregate demand
ExplanationA decrease in aggregate demand shifts the Phillips Curve to the right.
#18
In the long run, according to the adaptive expectations Phillips Curve, what happens when unemployment falls below the natural rate?
Inflation increases
ExplanationBelow the natural rate, unemployment leads to inflation in the long run according to the adaptive expectations Phillips Curve.
#19
What happens to the Phillips Curve if policymakers enact contractionary fiscal policy?
Shifts to the left
ExplanationEnacting contractionary fiscal policy shifts the Phillips Curve to the left.
#20
According to the Phillips Curve, what is the relationship between inflation and unemployment in the long run?
Neutral
ExplanationIn the long run, inflation and unemployment have a neutral relationship according to the Phillips Curve.
#21
What is the name given to the concept that suggests there is no permanent trade-off between inflation and unemployment?
Natural rate hypothesis
ExplanationThe natural rate hypothesis suggests there's no permanent trade-off between inflation and unemployment.
#22
What impact does an increase in the labor force participation rate have on the Phillips Curve?
Shifts the curve leftward
ExplanationAn increase in the labor force participation rate shifts the Phillips Curve leftward.
#23
What effect does an increase in aggregate demand have on the Phillips Curve in the short run?
Shifts it rightward
ExplanationAn increase in aggregate demand shifts the Phillips Curve rightward in the short run.
#24
According to the natural rate hypothesis, what happens to the Phillips Curve in the long run?
It becomes vertical
ExplanationIn the long run, the Phillips Curve becomes vertical under the natural rate hypothesis.
#25
What role does the expectations-augmented Phillips Curve play in explaining stagflation?
It suggests that expectations of higher inflation can cause higher inflation itself
ExplanationThe expectations-augmented Phillips Curve suggests that expectations of higher inflation can lead to higher inflation itself, explaining stagflation.
