FAQs on AD-AS Approach of Income Determination - The investment function, Macroeconomics Video Lecture - Macro Economics - B Com

1. What is the investment function in the AD-AS approach of income determination?
Ans. The investment function in the AD-AS approach of income determination refers to the relationship between the level of investment and the interest rate. It shows how changes in the interest rate can affect the level of investment in an economy. As the interest rate decreases, the cost of borrowing money for investment decreases, leading to an increase in investment. Conversely, as the interest rate increases, the cost of borrowing increases, leading to a decrease in investment.
2. How does the investment function affect aggregate demand and aggregate supply?
Ans. The investment function affects both aggregate demand (AD) and aggregate supply (AS) in the AD-AS approach of income determination. An increase in investment leads to an increase in aggregate demand because it increases the total spending in the economy. This can result in higher output and employment levels. On the other hand, a decrease in investment leads to a decrease in aggregate demand, which can lead to lower output and employment levels. The investment function also affects aggregate supply indirectly by influencing the level of productivity and potential output in the economy.
3. What factors influence the investment function in the AD-AS approach?
Ans. Several factors influence the investment function in the AD-AS approach of income determination. The most significant factor is the interest rate. As discussed earlier, a decrease in the interest rate stimulates investment, while an increase in the interest rate discourages investment. Other factors that influence the investment function include business confidence, technological advancements, government policies, and the availability of credit. Higher business confidence, favorable government policies, and improved access to credit can all contribute to increased investment, while the opposite conditions can lead to decreased investment.
4. How does the investment function contribute to economic growth?
Ans. The investment function plays a crucial role in promoting economic growth. When investment levels increase, it leads to higher spending on capital goods, such as machinery, equipment, and infrastructure. This increased investment in productive assets can lead to higher levels of productivity, which, in turn, can lead to higher economic output and growth. Additionally, investment can stimulate innovation and technological advancements, which are key drivers of long-term economic growth. Therefore, a robust investment function is essential for sustained economic growth.
5. How does the investment function interact with other components of aggregate demand?
Ans. The investment function interacts with other components of aggregate demand, such as consumption, government spending, and net exports. Increases in investment can lead to a multiplier effect, where higher investment levels stimulate increased consumption and overall spending in the economy. This, in turn, can lead to higher levels of output and employment. Conversely, a decrease in investment can have a negative multiplier effect, leading to lower consumption and spending. Therefore, the investment function has a significant impact on the overall level of aggregate demand and the performance of the economy as a whole.
