Which of the following statements accurately describe the impact of investment spending on long-run aggregate supply (LRAS)? Select all that apply.

Investment spending plays a crucial role in shaping long-run aggregate supply (LRAS) because it increases the economy's productive capacity. When businesses invest in new machinery, technology, or facilities, they become more efficient and can produce more goods and services over time. This increase in production capacity leads to a rightward shift in the LRAS curve, indicating growth in the economy. For example, if a factory invests in a new production line, it can create more products with the same amount of labor, boosting overall output. Thus, higher investment spending generally results in a stronger and more productive economy in the long run.
