Which of the following factors can shift the long-run aggregate supply curve?

The long-run aggregate supply (LRAS) curve represents the economy's potential output when resources are fully employed, and it shifts due to changes in factors that affect the productive capacity of an economy. Among the options provided, technological advancements stand out as a crucial factor that can shift the LRAS curve.

Technological advancements improve the efficiency and productivity of production processes, allowing firms to produce more output with the same amount of inputs. As a result, the economy can achieve a higher level of potential output at the same price level, thus shifting the LRAS curve to the right. This reflects an increase in the economy's capacity to produce goods and services over the long run.

While investment increases can also lead to a potential shift in production capacity, it is often the technological enhancements arising from those investments that fundamentally drive shifts in long-run aggregate supply. Input prices and seasonal weather variations typically impact the short-run aggregate supply curve rather than the long-run supply.
