Price stability refers to the degree to which prices for goods, services, or securities remain constant over a specified period. It is a key economic objective to avoid long periods of inflation or deflation, contributing to overall economic stability and predictability.
Importance
- Economic Predictability: Provides a predictable environment for consumers and businesses for planning and investing.
- Preserves Purchasing Power: Maintains the value of money over time, protecting incomes and savings.
- Minimizes Speculative Risks: Ensures that prices reflect true value, reducing the likelihood of asset bubbles and speculative behavior.
- Enhances Confidence: Boosts confidence in the economy among stakeholders, including businesses, consumers, and investors.
Measurement of Price Stability
Consumer Price Index (CPI)
The Consumer Price Index (CPI) measures the average change over time in the prices paid by consumers for a basket of goods and services.
Producer Price Index (PPI)
The Producer Price Index (PPI) measures the average change over time in the selling prices received by domestic producers for their output.
Core Inflation
Core inflation excludes volatile items such as food and energy prices from the inflation measure to provide a more stable view of long-term price trends.
Formulae
The general formula for calculating inflation, a key measure of price stability, can be represented as:
Factors Affecting Price Stability
Monetary Policy
Central banks influence price stability through interest rates and other monetary tools.
Supply and Demand
Changes in supply and demand for goods and services can cause fluctuations in prices.
External Shocks
Events such as oil price shocks, natural disasters, or geopolitical conflicts can impact price stability.
Fiscal Policy
Government spending and taxation policies also play a role in maintaining price stability.
