Savings play a crucial role in both personal finance and the broader economy. This entry will provide a comprehensive overview of the concept of savings, examining definitions, historical context, types, key events, mathematical models, and their importance and applicability.
Historical Context
Savings have been a cornerstone of economic theory and practice for centuries. The idea of accumulating wealth for future use dates back to ancient civilizations, where individuals stored food and precious metals. In the modern era, savings became a formal concept in economic theory, particularly through the works of economists like John Maynard Keynes, who explored the relationship between savings, consumption, and economic growth.
Definitions
- Saving: A flow measure that refers to the excess of income over consumption within a given period.
- Savings: A stock measure that refers to the accumulated quantity of assets held, derived from the continuous flow of saving.
- Average Propensity to Save (APS): The ratio of total saving to total income.
- Marginal Propensity to Save (MPS): The ratio of the change in saving to the change in income.
- Interest-Elasticity of Saving: The responsiveness of the amount saved to changes in the interest rate.
Types and Categories
Personal Savings
Savings accumulated by individuals for future personal use, such as emergency funds, retirement, or major purchases.
Corporate Savings

Key Events

Mathematical Formulas and Models
Average Propensity to Save (APS)
- \( S \) = Total Savings
- \( Y \) = Total Income
Marginal Propensity to Save (MPS)
- \( \Delta S \) = Change in Savings
- \( \Delta Y \) = Change in Income
Interest-Elasticity of Saving
- \( \Delta S \) = Change in Savings
- \( S \) = Initial Savings
- \( \Delta r \) = Change in Interest Rate
- \( r \) = Initial Interest Rate
