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

Q1(b)8 marks
With reference to Extract B, examine whether the demand for delivered food is price inelastic and income elastic.
Mark splitKnowledge 2Application 2Analysis 2Evaluation 2

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.
Q1(c)12 marks
With reference to Extract C, discuss the likely effects of increasing integration within the food delivery market.

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.
Q1(d)OptionalEvaluate25 marks
Evaluate the microeconomic and macroeconomic effects of a depreciation of the pound. Refer to restaurants or other food delivery services in your answer.
Mark splitKnowledge 4Application 4Analysis 8Evaluation 9

TopicInternational economics

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.
Q1(e)OptionalEvaluate25 marks
Evaluate the microeconomic and macroeconomic effects of significant increases in the minimum wage. Refer to restaurants or other food delivery services in your answer.
Mark splitKnowledge 4Application 4Analysis 8Evaluation 9

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

Q2(a)Explain5 marks
Explain what is meant by the Lewis model. Refer to Extract D in your answer.
Mark splitKnowledge 2Application 2Analysis 1

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.
Q2(b)Examine8 marks
Examine two demographic factors influencing development in Kenya.
Mark splitKnowledge 2Application 2Analysis 2Evaluation 2

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.
Q2(c)12 marks
Using the example of cut flowers (Extract F), discuss how the concept of absolute advantage may lead to growth in Kenya. Use numerical or diagrammatic analysis in your answer.
Mark splitKnowledge 2Application 2Analysis 4Evaluation 4

TopicInternational economics

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.
Q2(d)OptionalEvaluate25 marks
Evaluate the microeconomic and macroeconomic effects of decreasing interest rates in Kenya, or another developing country of your choice.
Mark splitKnowledge 4Application 4Analysis 8Evaluation 9

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.
Q2(e)OptionalEvaluate25 marks
Evaluate the microeconomic and macroeconomic strategies that could be used to promote development in Kenya, or another developing country of your choice.
Mark splitKnowledge 4Application 4Analysis 8Evaluation 9

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.
