1. What is Marginal Propensity to Consume?

The Marginal Propensity to Consume (MPC) measures the proportion of additional income that is spent on consumption. It's a key concept in Keynesian economics that helps understand consumer behavior and the multiplier effect.

2. How Does the MPC Calculator Work?

The calculator uses the MPC formula:

\[ MPC = \frac{\Delta C}{\Delta Y} = \frac{C_2 - C_1}{Y_2 - Y_1} \]

Where:

\( \Delta C \) — Change in consumption
\( \Delta Y \) — Change in income
\( C_1 \) — Initial consumption level
\( C_2 \) — New consumption level
\( Y_1 \) — Initial income level
\( Y_2 \) — New income level

Explanation: MPC ranges between 0 and 1. A higher MPC means more of additional income is spent rather than saved.

3. Importance of MPC in Macroeconomics

Details: MPC is crucial for determining the multiplier effect in an economy, influencing fiscal policy decisions, and predicting consumer spending patterns during economic changes.

4. Using the Calculator

Tips: Enter consumption and income values in dollars. Ensure Y₂ is different from Y₁ (denominator cannot be zero). Values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical MPC value?
A: In developed economies, MPC typically ranges between 0.6 and 0.9, meaning people spend 60-90% of additional income.

Q2: How does MPC relate to MPS?
A: Marginal Propensity to Save (MPS) = 1 - MPC, since additional income is either spent or saved.

Q3: Does MPC vary across income levels?
A: Yes, lower-income households generally have higher MPCs than wealthier households.

Q4: How is MPC used in fiscal policy?
A: Policymakers consider MPC when designing tax cuts or stimulus packages to estimate their economic impact.

Q5: Can MPC be greater than 1?
A: Normally no, but in rare cases where people spend more than their additional income (using savings or credit), it's theoretically possible.
