Examiner insight
- What to cover
- Read the direction of the subsidy change from Figure 1. A smaller subsidy raises train operating costs, so supply shifts left and rail fares rise. Link the size of the fare change to the size of the subsidy cut.
- Diagram
- Supply and demand for rail travel. Show supply shifting left as the subsidy falls, with the vertical gap between the curves equal to the subsidy per journey. Label P1 to P2 and Q1 to Q2.
- Watch out
- Shifting demand rather than supply, or drawing the diagram without stating the new fare and quantity.
TopicHow markets work
Examiner insight
- What to cover
- Pick two demand determinants and tie each to Figure 2. Real incomes with rail travel as a normal good, and the price of substitutes such as petrol, car use or coach travel. Explain each shift in demand.
- Evaluation
- Judge which factor explains more of the movement in Figure 2. Note fares, service quality and commuting patterns could explain the same trend, so the link is not certain.
- Watch out
- Describing the trend in Figure 2 without explaining why demand shifted.
TopicGovernment intervention in markets
Examiner insight
- What to cover
- Define nationalisation. Explain the chain: state ownership removes the profit motive, so cost cutting and redundancies are less likely, union bargaining power rises, and pay and job security for rail employees may improve.
- Evaluation
- Weigh this against the taxpayer cost, the opportunity cost of subsidy and X inefficiency. Government may still cut jobs to control spending. Depends on budget pressure, union strength and the time period.
- Watch out
- Writing about passengers and fares instead of keeping the whole answer on employees.
TopicMarket structures
Examiner insight
- What to cover
- Define natural monopoly as one firm supplying the whole market at lower average cost. Apply to the track network: huge fixed costs mean long run average cost keeps falling, so duplicating track would waste resources.
- Diagram
- Natural monopoly diagram. Falling LRAC cutting demand where AR lies below AC, with MC below AC throughout. Label the loss made at the allocatively efficient output where AR equals MC.
- Evaluation
- Weigh the track against train operating services, where franchising allows competition for the market. Depends on whether average cost is still falling at current demand, and on regulation to stop monopoly pricing.
- Watch out
- Treating the whole rail industry as one natural monopoly instead of separating infrastructure from train operations.
TopicMarket structures
Examiner insight
- What to cover
- Define third degree price discrimination and the conditions needed. Explain how off peak passengers with elastic demand pay lower fares, how spare capacity gets used, and how extra profit can fund network investment.
- Diagram
- Two market third degree diagram. Elastic off peak market with a lower price, inelastic peak market with a higher price, same MC in both. Label each P and Q and the consumer surplus transferred.
- Evaluation
- Weigh cheaper off peak travel against higher peak fares paid by commuters with inelastic demand. Depends on whether profit is reinvested, and whether passengers can actually switch travel times.
- Watch out
- Explaining the benefits to the train operator when the question asks about benefits to passengers.
Section C
Examiner insight
- What to cover
- Trace the effects through linked markets. Demand for oil and petrol cars falls, prices and jobs there fall, demand for lithium, batteries and charging points rises, and negative externalities from tailpipe emissions shrink.
- Diagram
- Negative consumption externality diagram for petrol cars, showing MSB below MPB and the welfare loss triangle shrinking. Alternatively supply and demand for oil with demand shifting left. Label P, Q and the welfare area.
- Evaluation
- Weigh cleaner air against battery mining externalities, emissions from electricity generation and structural unemployment in oil regions. Depends on the speed of switching, elasticity of demand for cars and the energy mix.
- Watch out
- Drifting into macroeconomic effects such as growth and the balance of payments when the question says microeconomic.
TopicMarket structures
Examiner insight
- What to cover
- Define monopsony as a single dominant buyer. Explain how Amazon restricts the quantity it buys and pays publishers below the competitive price, cutting publisher profit, author royalties, the range of titles and publishing jobs.
- Diagram
- Monopsony input market diagram. Supply as the average cost of the input, marginal cost curve above it, buyer choosing where MC equals MRP. Label the lower price and quantity against the competitive outcome.
- Evaluation
- Weigh against lower book prices for consumers if cost savings are passed on, and countervailing power from large publishers. Depends on how contestable book retailing is and on regulation. Judge over the long run.
- Watch out
- Describing monopoly selling power instead of monopsony buying power.
