Section A
Case study
The food delivery industry
Extracts: A: National Minimum Wage rises are more significant for 23 to 25-year-olds · B: What is the true cost of the food delivery service? · C: Integration in the third‐party food delivery industry
In the extracts: Deliveroo, Amazon, National Minimum Wage, National Living Wage, Drivers, Food, CMA, Uber Eats and Deliveroo, Amazon Restaurants, Uber Eats Others
TopicMarket failure
TopicHow markets work
Examiner insight
- What to cover
- Use Extract B to estimate both elasticities. Price inelastic means a price rise raises total revenue. Income elastic and positive means delivery is a luxury, so demand swings sharply with income.
- Diagram
- Optional: demand curves of different slopes, or a revenue calculation.
- Evaluation
- Comment on the reliability of the data and on whether the values hold over a longer period as habits change.
- Watch out
- Stating the elasticities without using the extract figures to justify them.
TopicGovernment intervention in marketsRevenues, costs and profitsAggregate demand
Examiner insight
- What to cover
- Integration between platforms and restaurants raises concentration. Trace the chain to greater market power, possible higher commission for restaurants and higher prices for consumers, set against economies of scale.
- Diagram
- Oligopoly or monopoly diagram, or the falling LRAC curve showing economies of scale.
- Evaluation
- Weigh lower unit costs and better service against reduced competition, higher prices and the CMA's likely response. Depends on how contestable the market remains.
- Watch out
- Describing types of integration instead of analysing the effects of increasing integration on this market.
Examiner insight
- What to cover
- Cover both sides. Micro: dearer imported food and ingredients raise restaurant costs and prices. Macro: net exports rise, AD rises, imported inflation, effects on the current account.
- Diagram
- AD and AS with AD shifting right and SRAS shifting left, plus an exchange rate diagram.
- Evaluation
- Judge micro and macro. Depends on the Marshall Lerner condition, the J curve in the short run, and the import intensity of the food industry.
- Watch out
- Only covering the trade balance. The microeconomic cost effects on named firms carry equal weight.
TopicLabour market
Examiner insight
- What to cover
- Cover both sides. Micro: higher labour costs for restaurants and couriers, possible job losses, substitution towards capital. Macro: higher incomes for the low paid, stronger AD, cost push inflation, lower welfare spending.
- Diagram
- Labour market diagram with the minimum wage above equilibrium showing excess supply of labour.
- Evaluation
- Judge micro and macro. Depends on the elasticity of demand for labour, whether the market is monopsonistic, and the size of the increase.
- Watch out
- Assuming unemployment must follow. Monopsony power means a higher minimum wage can raise both wages and employment.
Section B
Case study
Sub‐Saharan Africa – growth and development
Extracts: D: Growth and development in Africa: 'Africa has a massive opportunity as a low‐cost · E: The demography of Kenya – ‘Demography will shape Africa’s future’ · F: Kenya has an absolute advantage in cut flowers · G: Changes in interest rates in sub‐Saharan Africa
In the extracts: Kenya, Africa, Saharan Africa, Netherlands, Kenyans, Robert Matsiko, Demography, Mr Matsiko, Falling, Nairobi
TopicEmerging and developing economies
Examiner insight
- What to cover
- The Lewis model describes surplus labour moving from low productivity subsistence agriculture into higher productivity manufacturing, raising output and saving. Link to the structural change described in Extract D.
- Diagram
- Optional: two sector diagram or a PPF shifting outwards.
- Watch out
- Describing rural to urban migration in general without naming the productivity and saving mechanism at the centre of the model.
TopicInternational economicsMacroeconomic objectives and policy
Examiner insight
- What to cover
- Give two demographic factors and develop each. Options include a high birth rate and young dependency ratio, rapid urbanisation, life expectancy and health, and net migration.
- Evaluation
- Say which factor matters most for Kenya and note that a young population is a burden now but a potential demographic dividend later.
- Watch out
- Drifting into non demographic factors such as corruption or infrastructure. These earn nothing here.
Examiner insight
- What to cover
- Kenya can produce cut flowers using fewer resources than competitors because of its climate and low labour costs. Show the gain from specialising and trading, using output figures or a PPF.
- Diagram
- PPF for Kenya and a trading partner, or an output table showing total production rising after specialisation.
- Evaluation
- Weigh export earnings and employment against primary product dependency, volatile world prices, the Prebisch Singer effect and environmental cost. Depends on diversification.
- Watch out
- The question names absolute advantage. Writing about comparative advantage and opportunity cost ratios misses the concept asked for.
TopicMacroeconomic objectives and policyEmerging and developing economies
Examiner insight
- What to cover
- Cover both sides. Micro: cheaper borrowing for farmers and small firms, more investment. Macro: higher AD, a weaker shilling, imported inflation, faster growth and possible capital outflow.
- Diagram
- AD and AS with AD shifting right, plus an exchange rate diagram showing depreciation.
- Evaluation
- Judge micro and macro. Depends on how developed the banking sector is, the share of the population with bank accounts, and the inflation risk in a developing economy.
- Watch out
- Assuming monetary policy works as it does in the UK. Limited financial inclusion weakens the transmission mechanism in Kenya.
TopicEmerging and developing economies
Examiner insight
- What to cover
- Cover both sides. Micro: education, health, microfinance, property rights, infrastructure. Macro: FDI, aid, debt relief, export diversification, exchange rate policy, industrialisation.
- Diagram
- LRAS or PPF shifting right; a Lewis style structural shift diagram is also acceptable.
- Evaluation
- Judge micro and macro. Rank interventionist against market led strategies and argue which suits Kenya. Depends on institutional quality, corruption and the time period.
- Watch out
- Listing strategies with no judgement. The 25 marks require a ranked and supported conclusion.
