What can lead to an outward shift in the long-run aggregate supply curve?

• A. Increases in government spending
• B. Decreases in consumer confidence
• C. Improvements in technology
• D. Higher taxes on businesses

Answer: (C)

The long-run aggregate supply (LRAS) curve represents the total output an economy can produce when utilizing its resources efficiently, and it is vertical at the natural level of output. An outward shift in this curve suggests an increase in the economy's productive capacity over time.

Improvements in technology are crucial for this outward shift because they enhance the efficiency of production processes. When new technologies are developed, they can lead to more efficient use of labor and capital, resulting in increased output without requiring a proportional increase in inputs. This technological advance allows industries to produce more goods and services, reflecting a higher potential output in the long run, thus shifting the LRAS curve to the right.

In contrast, increases in government spending or higher taxes on businesses pertain more to aggregate demand rather than the aggregate supply directly. Government spending can boost demand in the short run, but it does not directly impact the economy’s long-term productive capacity unless it specifically enhances infrastructure or technological capacity. Similarly, higher taxes on businesses can discourage investment, potentially reducing the productive capacity of the economy over time. Decreases in consumer confidence primarily affect aggregate demand by reducing spending and consumption, rather than enhancing the economy's production capabilities in the long run.

Therefore, improvements in technology stand out as the
