01Model
Build the economic model
Inflation is a sustained rise in the general price level. CPI weights a basket of household spending; demand-pull and cost-push accounts identify different mechanisms and policy implications.
For inflation and price stability, state the relationship between inflation and the relevant agents, then identify the ceteris-paribus conditions. The model is a disciplined simplification, not a complete description of reality.
- Define the central variables precisely.
- Identify the agents making decisions.
- State what is held constant and why that matters.
02Evidence
Apply evidence and data
Annual CPI inflation falls from 8% to 4% while food prices remain much higher than two years earlier.
Application in inflation and price stability means using scale, direction, timing and source to alter the argument. Explain how the evidence changes the mechanism instead of merely naming the context or copying a figure.
- Check units, dates and whether values are nominal or real.
- Separate correlation from a supported causal inference.
- Identify winners, losers and the appropriate counterfactual.
03Analyse
Develop the mechanism
Demand pressure or cost shock → firms adjust prices and output → real incomes, interest expectations and competitiveness change → distribution depends on contracts and assets.
Carry this inflation and price stability chain far enough to answer the question: identify the agent's response, the resulting market or macroeconomic change and why the outcome matters.
- Explain each arrow in the chain.
- Use the diagram or calculation in the written analysis.
- Distinguish short-run adjustment from longer-run response.
04Evaluate
Evaluate assumptions and magnitude
A single average rate hides different household baskets, quality change and regional effects; falling inflation means slower price growth, not generally falling prices.
Evaluation of inflation and price stability should change confidence in the result. Test elasticity, time lags, scale, incentives, distribution and unintended effects rather than adding a generic “however”.
- Which assumption is most fragile?
- Would a different elasticity reverse or only weaken the result?
- What evidence could change the judgement?
05Judge
Reach an informed judgement
For inflation and price stability, choose the argument with the greatest contextual importance and explain why it outweighs the alternative. State the conditions under which it holds rather than repeating the introduction.
The opportunity cost and distributional effect of inflation matter. Political preferences may affect objectives, but the exam judgement must rest on transparent assumptions and evidence rather than ideology.
- Answer the exact command and scope.
- Rank the decisive factors.
- State a condition, timeframe and possible reason to revise the conclusion.
From theory to a testable claim
Inflation is a sustained rise in the general price level. CPI weights a basket of household spending; demand-pull and cost-push accounts identify different mechanisms and policy implications.
Applied taskAnnual CPI inflation falls from 8% to 4% while food prices remain much higher than two years earlier.
Causal chain
Demand pressure or cost shock → firms adjust prices and output → real incomes, interest expectations and competitiveness change → distribution depends on contracts and assets.
Applied taskRewrite the inflation and price stability chain with one piece of numerical or contextual evidence at the link where it changes the expected magnitude.
Evaluation that does work
A single average rate hides different household baskets, quality change and regional effects; falling inflation means slower price growth, not generally falling prices.
Applied taskExplain whether this consideration weakens, delays, redistributes or reverses the predicted inflation and price stability outcome.
