Inflation and Price Stability
How inflation is measured and how demand, costs and expectations affect different economic groups.
How to study for GCSE Economics
Learn each definition and diagram as a causal model, practise calculations with units, apply evidence to the stated context and qualify conclusions with realistic trade-offs.
Core concepts
Concept 1
Inflation is a sustained rise in the general price level, commonly measured using the Consumer Prices Index.
Exam cue: Distinguish a rising price level from one product's price change and from a falling inflation rate.
Concept 2
Demand-pull inflation arises from strong total spending, while cost-push inflation arises from rising production costs.
Exam cue: Trace the stated cause through demand or production cost to the general price level.
Concept 3
Inflation changes real purchasing power, saving, borrowing, costs, competitiveness and the reliability of economic decisions.
Exam cue: Evaluate effects according to whether incomes, interest rates or contracts adjust.
Risk pitfalls and guardrails
Saying lower inflation means the price level is falling.
Guardrail: Do not stop at a definition or generic advantage: show the mechanism, keep units and diagram labels accurate, and separate board-specific paper claims from the England common core.
Treating CPI as the price of a single fixed item.
Guardrail: Do not stop at a definition or generic advantage: show the mechanism, keep units and diagram labels accurate, and separate board-specific paper claims from the England common core.
Claiming inflation harms all borrowers and benefits all savers in every context.
