Headline inflation is a key economic indicator that measures the total inflation within an economy. Unlike core inflation, which excludes volatile food and energy prices, headline inflation includes all goods and services. This broad measure provides a comprehensive overview of price changes that impact consumers.
Types/Categories of Inflation
- Demand-Pull Inflation: Occurs when demand for goods and services exceeds supply.
- Cost-Push Inflation: Triggered by an increase in the cost of production, such as rising oil prices.
- Built-In Inflation: Results from adaptive expectations, where businesses increase prices in anticipation of future inflation.
Inflation Rate Formula:
$$ \text{Inflation Rate} (\%) = \left( \frac{\text{CPI}_{\text{current period}} - \text{CPI}_{\text{previous period}}}{\text{CPI}_{\text{previous period}}} \right) \times 100 $$
Where CPI is the Consumer Price Index.
