Practise Edexcel IAL Economics 2.3.1.1o by defining deflation, explaining AD and SRAS causes, and evaluating policy lags and factor combinations.
In July 2021 Rwanda's inflation rate was -1.1\% and in November 2021 it was -3.4\%.
Evaluate possible causes of deflation. Refer to a country of your choice in your answer.

Knowledge, Application and Analysis ( 12 marks) - indicative content
- Understanding of deflation
- "In July 2021 Rwanda's inflation rate was -1.1\% and in November 2021 it was −3.4%′′
Possible causes include:
- Decrease in AD as a result of -
- lower consumption/higher savings
- lower levels of gross/net investment
- lower government spending/public expenditure
- lower net trade/fall in exports/increase in imports
- deflationary fiscal policy e.g. lower rates of direct taxes
- deflationary monetary policy e.g. lower money supply/increase in the base rate of interest
- expectations of deflation means that consumers may delay their purchases to see if the price decreases again
- Increase in SRAS as a result of -
- decrease in indirect taxes
- fall in costs of raw materials and energy
- increase in the external value of the currency making imports relatively cheaper
- Increase in LRAS as a result of -
- competition policy
- increases in productivity
- increase in net migration
- technological advancements
- improvements in education and skills

Level 0
Level 1
1-3
Level 2
4-6
Limited application of knowledge and understanding to economic problems in context.
A narrow response or superficial, only two-stage chains of reasoning in terms of cause and/or consequence.
Level 3
7-9
Demonstrates accurate knowledge and understanding of economic terms, principles, concepts, theories and models.
Ability to apply knowledge and understanding to some elements of the question. Some evidence and contextual references are evident in the answer.
Analysis is clear and coherent. Chains of reasoning in terms of cause and/or consequence are evident, but they may not be developed fully, or some stages are omitted.
Level 4
10-12
Demonstrates accurate and precise knowledge and understanding of economic terms, principles, concepts, theories and models. Ability to link knowledge and understanding in context using appropriate examples which are fully integrated to address the broad elements of the question.
Analysis is clear, coherent, relevant and focused. The answer demonstrates logical and multi-stage chains of reasoning in terms of cause and/or consequence.
Evaluation (8 marks) - indicative content
- Significance of the most important factor changes over time
- It is likely to be a combination of factors contributing to deflation
- Magnitude of the deflation will be dependent on the size of any shifts in AD and AS: it is likely to be relatively large for Rwanda
- Demand-pull deflation (decrease in AD) is often seen as more negative as the lack of AD is what causes the deflationary pressure
- Fiscal policy and/or monetary policy takes time to impact AD
- Cost-push deflation (increase in SRAS) is often seen as a more positive cause as the supply side is improving
- If the external value of the currency decreases then the relative price of imports will increase
- Prices of raw materials and oil are highly volatile and likely to increase as AD increases as the world economy recovers
- Supply-side impacts (increase in LRAS) are likely to have a long-term effect only causing deflation after a significant time lag
