Definition of Economic Multiplier
An Economic Multiplier is a vital economic concept that refers to an economic factor that, when increased or altered, results in greater changes across various related economic variables. Essentially, it describes how an initial change in spending, especially in government expenditures, can lead to more significant variations in overall economic output, often measured in terms of Gross Domestic Product (GDP). To put it simply, spending $1 might stimulate the economy by impacting total output—yielding more than just that original dollar!

| Application | Used for GDP and national income analysis | Used in banking and monetary policy |
| Effect Level | Macro-economic impact | Banking system efficiency |
| Multiplication Effect | Dynamic across industries | Typically lower than the economic multiplier |
