What is the Phillips curve?

  1. A graphical representation of the relationship between inflation and unemployment.

  2. A graphical representation of the relationship between inflation and interest rates.

  3. A graphical representation of the relationship between unemployment and interest rates.

  4. A graphical representation of the relationship between inflation and economic growth.


Correct Option: A
Explanation:

The Phillips curve is a graphical representation of the relationship between inflation and unemployment. It shows that there is a trade-off between the two, meaning that if one increases, the other must decrease.

What is the shape of the Phillips curve?

  1. A downward-sloping curve.

  2. An upward-sloping curve.

  3. A horizontal line.

  4. A vertical line.


Correct Option: A
Explanation:

The Phillips curve is typically downward-sloping, meaning that as inflation increases, unemployment decreases. This is because when inflation is high, businesses are more likely to hire workers in order to meet demand, which leads to lower unemployment.

What is the long-run Phillips curve?

  1. A vertical line at the natural rate of unemployment.

  2. A horizontal line at the natural rate of unemployment.

  3. A downward-sloping curve that intersects the vertical line at the natural rate of unemployment.

  4. An upward-sloping curve that intersects the vertical line at the natural rate of unemployment.


Correct Option: A
Explanation:

The long-run Phillips curve is a vertical line at the natural rate of unemployment. This means that in the long run, there is no trade-off between inflation and unemployment. If inflation is above the natural rate, unemployment will eventually rise to the natural rate. If inflation is below the natural rate, unemployment will eventually fall to the natural rate.

What is the short-run Phillips curve?

  1. A downward-sloping curve that intersects the vertical line at the natural rate of unemployment.

  2. A horizontal line at the natural rate of unemployment.

  3. A vertical line at the natural rate of unemployment.

  4. An upward-sloping curve that intersects the vertical line at the natural rate of unemployment.


Correct Option: A
Explanation:

The short-run Phillips curve is a downward-sloping curve that intersects the vertical line at the natural rate of unemployment. This means that in the short run, there is a trade-off between inflation and unemployment. If inflation is above the natural rate, unemployment will be below the natural rate. If inflation is below the natural rate, unemployment will be above the natural rate.

What is the natural rate of unemployment?

  1. The rate of unemployment that is consistent with stable inflation.

  2. The rate of unemployment that is consistent with full employment.

  3. The rate of unemployment that is consistent with zero inflation.

  4. The rate of unemployment that is consistent with maximum employment.


Correct Option: A
Explanation:

The natural rate of unemployment is the rate of unemployment that is consistent with stable inflation. This is the rate of unemployment that would exist in the long run if there were no shocks to the economy.

What is the relationship between the Phillips curve and monetary policy?

  1. Monetary policy can be used to shift the Phillips curve.

  2. Monetary policy can be used to move the economy along the Phillips curve.

  3. Monetary policy can be used to eliminate the trade-off between inflation and unemployment.

  4. Monetary policy has no effect on the Phillips curve.


Correct Option: A
Explanation:

Monetary policy can be used to shift the Phillips curve by changing the expected rate of inflation. If the central bank raises the expected rate of inflation, the Phillips curve will shift up. If the central bank lowers the expected rate of inflation, the Phillips curve will shift down.

What is the relationship between the Phillips curve and fiscal policy?

  1. Fiscal policy can be used to shift the Phillips curve.

  2. Fiscal policy can be used to move the economy along the Phillips curve.

  3. Fiscal policy can be used to eliminate the trade-off between inflation and unemployment.

  4. Fiscal policy has no effect on the Phillips curve.


Correct Option: A
Explanation:

Fiscal policy can be used to shift the Phillips curve by changing the level of aggregate demand. If the government increases aggregate demand, the Phillips curve will shift up. If the government decreases aggregate demand, the Phillips curve will shift down.

What are the limitations of the Phillips curve?

  1. The Phillips curve is only valid in the short run.

  2. The Phillips curve is only valid in the long run.

  3. The Phillips curve is only valid in the medium run.

  4. The Phillips curve is only valid in the very long run.


Correct Option: A
Explanation:

The Phillips curve is only valid in the short run because in the long run, the economy will eventually return to the natural rate of unemployment. This means that in the long run, there is no trade-off between inflation and unemployment.

What are the implications of the Phillips curve for economic policy?

  1. Economic policy should focus on achieving a low rate of inflation and a low rate of unemployment.

  2. Economic policy should focus on achieving a high rate of inflation and a high rate of unemployment.

  3. Economic policy should focus on achieving a low rate of inflation and a high rate of unemployment.

  4. Economic policy should focus on achieving a high rate of inflation and a low rate of unemployment.


Correct Option: A
Explanation:

Economic policy should focus on achieving a low rate of inflation and a low rate of unemployment because this is the combination that is most beneficial for the economy. A low rate of inflation will help to keep prices stable and a low rate of unemployment will help to ensure that everyone who wants a job can find one.

What is the difference between the Phillips curve and the aggregate supply curve?

  1. The Phillips curve shows the relationship between inflation and unemployment, while the aggregate supply curve shows the relationship between the price level and the quantity of output supplied.

  2. The Phillips curve shows the relationship between inflation and unemployment, while the aggregate supply curve shows the relationship between the price level and the quantity of output demanded.

  3. The Phillips curve shows the relationship between inflation and the quantity of output supplied, while the aggregate supply curve shows the relationship between the price level and the quantity of output demanded.

  4. The Phillips curve shows the relationship between inflation and the quantity of output demanded, while the aggregate supply curve shows the relationship between the price level and the quantity of output supplied.


Correct Option: A
Explanation:

The Phillips curve shows the relationship between inflation and unemployment, while the aggregate supply curve shows the relationship between the price level and the quantity of output supplied. The Phillips curve is a short-run relationship, while the aggregate supply curve is a long-run relationship.

What is the difference between the Phillips curve and the NAIRU?

  1. The Phillips curve shows the relationship between inflation and unemployment, while the NAIRU shows the natural rate of unemployment.

  2. The Phillips curve shows the relationship between inflation and unemployment, while the NAIRU shows the non-accelerating inflation rate of unemployment.

  3. The Phillips curve shows the relationship between inflation and the quantity of output supplied, while the NAIRU shows the natural rate of unemployment.

  4. The Phillips curve shows the relationship between inflation and the quantity of output demanded, while the NAIRU shows the non-accelerating inflation rate of unemployment.


Correct Option: A
Explanation:

The Phillips curve shows the relationship between inflation and unemployment, while the NAIRU shows the natural rate of unemployment. The NAIRU is the rate of unemployment that is consistent with stable inflation.

What is the difference between the Phillips curve and the Beveridge curve?
