Types of Inflation — Core Concepts
Core Concepts
Inflation types are classified based on their underlying causes and characteristics. Demand-pull inflation occurs when aggregate demand exceeds supply capacity, typically during economic booms or expansionary policies.
Cost-push inflation results from rising production costs like wages, raw materials, or energy prices, forcing businesses to raise prices. Built-in inflation becomes self-perpetuating through expectations, creating wage-price spirals.
Hyperinflation involves extremely rapid price increases exceeding 50% monthly, usually due to monetary indiscipline. Stagflation combines high inflation with economic stagnation, challenging traditional policy tools.
Deflation involves sustained price decreases, potentially triggering economic depression. Disinflation refers to slowing inflation rates, while reflation involves deliberate efforts to raise price levels.
Creeping inflation describes mild, gradual price increases considered healthy for growth. India has experienced various inflation types, with cost-push inflation being most common due to oil import dependence and food price volatility.
The 2010-2013 period exemplified mixed inflation with both demand and supply pressures. RBI's inflation targeting framework, adopted in 2016, aims to anchor expectations and provide systematic responses to different inflation types.
Policy responses vary significantly - demand-pull inflation requires monetary tightening, cost-push inflation needs supply-side measures, while built-in inflation demands credible communication and expectation management.
Understanding these distinctions is crucial for effective macroeconomic policy and UPSC exam preparation.
Important Differences
