Study Notes
Marginal Propensity to Consume (MPC)
- The MPC represents the change in consumption spending for each change in income.
- The formula for calculating MPC is: MPC = (Change in Consumption) / (Change in Income).
- In the example provided, the MPC is 0.5. This means that for every additional unit of income earned, consumers spend 0.5 units on consumption.
- The calculation of MPC uses the following values:
- Autonomous investment of 106
- Consumption (C) of 50
- Autonomous Investment (B) of 0.8
- The calculation is performed as follows: MPC = (75 - 50) / (100 - 50) = 25 / 50 = 0.5
Key Assumptions
- The text assumes a specific amount of autonomous investment (106) and consumption (50).
- It also assumes a particular value for autonomous investment (B), which is 0.8.
Interpretation
- The MPC of 0.5 indicates that consumers will spend half of any additional income they earn, contributing to the overall economic activity.
- A higher MPC implies a stronger relationship between income and consumption.
- A lower MPC might indicate that individuals are saving more or spending their additional income on other goods and services.
- The MPC is a crucial concept in understanding the multiplier effect and economic growth.
