Which type of policy might negatively affect long-run aggregate supply?

• A. Expansionary fiscal policy
• B. Contractionary fiscal policy
• C. Supply-side economics policies
• D. Tax incentives for production

Answer: (B)

Contractionary fiscal policy can negatively affect long-run aggregate supply because this policy typically involves reducing government spending or increasing taxes. While these measures can help to combat inflation in the short run, they may reduce overall demand in the economy. A sustained decrease in demand can lead to lower levels of investment and decreased business profits, ultimately hindering production capacity over time.

In the long run, aggregate supply is influenced by factors such as technology, productivity, and resource availability. By reducing aggregate demand through contractionary fiscal measures, the economy may experience lower investment in capital goods and human resources, which are crucial for enhancing productive capacity. This can ultimately stifle growth and innovation, causing the long-run aggregate supply curve to shift leftward.

In summary, while contractionary fiscal policy can stabilize the economy in the short term, its implications on demand and investment can create obstacles for long-term growth and overall aggregate supply.
