What is the consequence of an increased labor force on the long-run aggregate supply curve?

• A. It shifts the curve to the left
• B. It has no effect on the curve
• C. It shifts the curve to the right
• D. It only affects short-run production

Answer: (C)

An increase in the labor force positively impacts the long-run aggregate supply curve by shifting it to the right. This shift represents an increase in the economy's productive capacity. When more individuals enter the labor market, there is a greater availability of labor to produce goods and services. This increase enables firms to expand production, leading to higher potential output in the economy.

Additionally, a larger labor force can enhance productivity and foster economic growth, as firms may also benefit from a wider variety of skills and experiences. This is crucial in the long run, as it translates into an increase in the overall supply of goods and services that an economy can sustain without triggering inflation.

The other options reflect misunderstandings of how labor supply affects long-term economic growth. A leftward shift would suggest a decrease in the economy's productive capacity, which does not occur with a growing labor force. Stating that there is no effect dismisses the fundamental impact of increased labor on production capabilities. Finally, indicating that it only affects short-run production overlooks the significance of labor force growth in enabling sustained long-term economic output improvements.
