Understanding Aggregate Demand, Supply, and the Phillips Curve

The video explores the relationship between aggregate demand, aggregate supply, and the Phillips curve, explaining both short-run and long-run perspectives. It discusses how economic cycles affect unemployment and inflation, and how demand shocks can shift these curves. The video also covers the impact of inflation expectations on supply and the Phillips curve, and factors that can cause shifts in long-run curves, such as technological advancements and global trade changes.

What does the short-run Phillips curve illustrate?

• The relationship between GDP and inflation.

• The relationship between inflation and unemployment in the short term.

• The effect of interest rates on inflation.

• The impact of fiscal policy on unemployment.

What does a vertical long-run Phillips curve indicate?

• Unemployment is unaffected by inflation in the long run.

• The economy is always at full employment.

• Inflation is constant regardless of unemployment.

• Unemployment decreases as inflation increases.

What happens when the economy experiences a negative demand shock?

• Aggregate demand increases, leading to higher inflation.

• Aggregate supply increases, leading to lower prices.

• Aggregate demand decreases, leading to higher unemployment.

• Aggregate supply decreases, leading to higher output.

How does a negative output gap affect the Phillips curve?

• It results in movement along the curve with lower inflation.

• It causes a shift to the right.

• It causes a shift to the left.

• It results in movement along the curve with higher unemployment.

What is the result of a positive demand shock on the economy?

• Higher output and lower price levels.

• Lower unemployment and higher inflation.

• Higher unemployment and lower inflation.

• Lower output and higher price levels.

How do inflation expectations affect the short-run aggregate supply?

• They have no effect on the supply curve.

• They cause the supply curve to shift to the right.

• They cause the supply curve to shift to the left.

• They cause the supply curve to become vertical.

What happens to the short-run Phillips curve when inflation expectations increase?

• It shifts to the left.

• It shifts to the right.

• It becomes steeper.

• It becomes flatter.

What can cause the long-run aggregate supply curve to shift to the right?

• A decrease in global trade.

• Technological advancements.

• An increase in unemployment.

• A decrease in inflation.

How can better technology affect the long-run Phillips curve?

• Shift it to the left.

• Make it vertical.

• Shift it to the right.

• Make it horizontal.

What might cause the long-run Phillips curve to shift to the right?

• An increase in worker skills.

• An increase in frictional unemployment.

• A decrease in global trade value.

• A decrease in inflation expectations.
