Model answer
What a good answer should say
- Correct answer: Use a three-step chain: cause changes incentives, incentives change demand or supply behaviour, and the new equilibrium affects welfare or resource allocation..
- It is correct because it links 3.2.3.3 inflation and deflation to policy transmission and keeps the reasoning within the evidence supplied by the question.
Explanation
Why this works
The reasoning should move from cause to transmission mechanism to consequence. Use a diagram, calculation or data point if it is relevant, then test the answer with Economics evaluation: size of effect, time period, elasticity or responsiveness, assumptions, and distribution of gains and losses.
This keeps the response specific to Economic performance rather than repeating a generic question template.
