Economics: Long-Run Equilibrium and Self-Adjustment

The video explains an economy in long-run equilibrium where aggregate demand and short-run aggregate supply intersect at a full employment output. It explores the effects of a shift in aggregate demand, leading to short-run price increases and output beyond sustainable levels. In the long run, wage increases cause the short-run aggregate supply to shift, returning output to full employment levels. This process is known as the long-run self-adjustment mechanism, suggesting that economies can self-correct without government intervention.

What does the intersection of the aggregate demand curve and the long-run aggregate supply curve represent?

• A recession

• A temporary economic boom

• Full employment output

• An unsustainable employment level

What does full employment output imply about the unemployment rate?

• It is unsustainable

• It is higher than usual

• It is at a sustainable level

• It is zero

What happens to prices and output when aggregate demand increases in the short run?

• Prices increase and output increases

• Prices decrease and output increases

• Prices increase and output decreases

• Prices decrease and output decreases

What might happen if unemployment falls below the sustainable rate?

• The situation becomes unsustainable

• The economy will stabilize

• Output will decrease

• Prices will decrease

In the long run, what causes the short-run aggregate supply curve to shift?

• An increase in labor prices

• A decrease in consumer optimism

• A decrease in government spending

• An increase in technology

What is a potential consequence of increased labor prices in the long run?

• A decrease in aggregate demand

• A shift in the short-run aggregate supply curve

• A decrease in prices

• A decrease in output

What is the long-run self-adjustment mechanism?

• A natural return to full employment output

• A temporary increase in unemployment

• A process where government intervention is necessary

• A permanent shift in aggregate demand

How does the economy return to full employment output in the long run?

• Through government intervention

• By increasing taxes

• By reducing consumer spending

• Via natural market adjustments

Why might a government choose to intervene in the economy?

• To eliminate all unemployment

• To permanently increase prices

• To prevent short-run deviations from full employment

• To decrease consumer spending

What role might the government play in managing the economy?

• To increase the unemployment rate

• To ensure permanent economic growth

• To adjust short-run deviations from full employment

• To eliminate all market fluctuations
