Model answer
What a good answer should say
- Correct answer: Distinguish aggregate demand and aggregate supply from the nearest misconception, then use price, quantity, incentives or welfare to explain the economic consequence..
- It is correct because it links 3.2.2.2 aggregate demand and aggregate supply analysis 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 How the macroeconomy works: the circular flow of income, aggregate demand/aggregate supply analysis and related concepts rather than repeating a generic question template.
