Definition
The Multiplier Effect is defined as the proportional change in final income that results from an injection or withdrawal of capital into the economy. It’s like the top-selling hit at an economic concert—one special change brings the whole audience to life (or to tears)—resulting in an amplified impact on overall economic output. 💸
The most basic formula to calculate the multiplier effect is:
\[ \text{Multiplier} = \frac{\text{Change in Income}}{\text{Change in Spending}} \]
