Understanding the Investment Multiplier Effect
Investment in an economy directly impacts income levels through the multiplier effect. In this scenario, an increase of 100 crores in investment will lead to a change in income, which can be calculated using the marginal propensity to consume (MPC).
Given Data
- Investment increase (I) = 100 crores
- Consumption function: c = 10 + 0.6y
- Marginal propensity to consume (MPC) = 0.6
Calculating the Multiplier
The multiplier (k) can be calculated using the formula:
k = 1 / (1 - MPC)
- Substituting the value of MPC:
- k = 1 / (1 - 0.6)
- k = 1 / 0.4
- k = 2.5
Determining the Change in Income
To find the total change in income (ΔY), we use the formula:
ΔY = k * ΔI
- Substituting the investment increase:
- ΔY = 2.5 * 100 crores
- ΔY = 250 crores
Conclusion
The increase in income resulting from a 100 crore increase in investment, given the consumption function, is:
- **250 crores**
Thus, the correct answer is **(a) 250**. This highlights the significant impact that investment can have on overall income levels due to the multiplier effect in an economy.
