Section B

Case study

Energy markets

Extracts: A: Uranium: the unloved metal · B: Irrational consumers pay the price · C: The economics of climate change

In the extracts: Uranium, Include, Kazakhstan, Energy, Japan, Shortage Figures, Prime Minister, Hinkley Point, Jon Yeomans, Supporters

Q6(a)Explain5 marks
With reference to Figure 1 and Extract A, explain why the price of uranium has ‘fallen to a 13-year low’ (Extract A, lines 2 and 3) in 2016. Include a supply and demand diagram in your answer.

TopicHow markets workGovernment intervention

Examiner insight

What to cover
Use Figure 1 and Extract A. Demand for uranium fell as nuclear plants closed while supply from mines stayed high. Excess supply at the old price forces price down.
Diagram
Uranium market with demand shifting left from D1 to D2, price falling P1 to P2 and quantity falling, with the excess supply at P1 marked.
Watch out
Describing the price fall without shifting a curve, or shifting supply when the extract points to falling demand.
Q6(b)10 marks
With reference to Extract A and your own knowledge, assess whether the supply of uranium is likely to be price elastic or price inelastic.
Mark splitKnowledge 2Application 2Analysis 2Evaluation 4

TopicHow markets work

Examiner insight

What to cover
Uranium mining has long lead times, high sunk costs and little spare capacity, so supply is price inelastic in the short run. Support this with Extract A evidence on mine closures.
Diagram
Steep supply curve where a large price change produces a small quantity change, with price elasticity of supply below one.
Evaluation
Weigh short run inelasticity against greater long run elasticity as new mines open, and against stockpiles which make supply more responsive. Judge with a stated time period.
Watch out
Giving the determinants of price elasticity of demand instead of those of price elasticity of supply.
Q6(c)Explain6 marks
With reference to Extract B, explain two likely reasons why many consumers of energy have not switched to suppliers offering lower prices.
Mark splitKnowledge 2Application 2Analysis 2

TopicHow markets workGovernment intervention

Examiner insight

What to cover
Use Extract B. Give two reasons such as imperfect information about tariffs, consumer inertia and the perceived time cost of switching. Explain why each blocks a rational response to lower prices.
Watch out
Naming two reasons without explaining why they stop consumers acting on the cheaper tariffs.
Q6(e)Discuss15 marks
Discuss the likely microeconomic effects of this decision on energy producers and consumers. Include a supply and demand diagram in your answer.

TopicHow markets workGovernment intervention

Examiner insight

What to cover
Trace the decision through the energy market. Show the effect on supply, price and quantity, then on consumer bills and surplus, and on producer revenue, profit and employment.
Diagram
Energy market with supply shifting right from S1 to S2, price falling P1 to P2 and quantity rising, with consumer surplus shown before and after.
Evaluation
Weigh consumer gains against producer losses, and note the size depends on the price elasticity of demand for energy and on long construction lead times. Judge the net effect.
Watch out
Covering consumers only when the question names both energy producers and consumers.
Q6(f)Optional20 marks
Using the concept of external costs, evaluate whether nuclear power is under-provided or over-provided in the energy market. Use an appropriate diagram in your answer.
Mark splitKnowledge 4Application 4Analysis 6Evaluation 6

TopicMarket failure

Examiner insight

What to cover
Identify external costs of nuclear power such as waste storage and accident risk, and the external benefit of displacing fossil fuels. Compare free market output with the social optimum.
Diagram
Externality diagram with MSC above MPC for over provision, or MSB above MPB for under provision, labelling Q1, Q* and the welfare loss triangle.
Evaluation
Weigh the size and probability of waste and accident costs against the carbon saved. Note these costs are hard to value over very long time periods. Judge.
Watch out
Asserting over or under provision without comparing market output to the social optimum on the diagram.
Q6(g)OptionalEvaluate20 marks
Evaluate ways in which government intervention could be used to reduce carbon emissions. Use at least one appropriate diagram in your answer.
Mark splitKnowledge 4Application 4Analysis 6Evaluation 6

TopicGovernment intervention

Examiner insight

What to cover
Take two or three of carbon tax, tradable permits, renewable subsidies and regulation. Show how each raises the private cost of emitting or lowers the cost of clean energy toward the social optimum.
Diagram
Carbon tax shifting supply left by the external cost so output falls from Q1 to Q*, or a permit market with vertical permit supply and the permit price set by demand.
Evaluation
Compare the certainty of regulation with the efficiency of a price signal. Demand for energy is inelastic, so a tax may cut emissions little and hit poorer households. Judge.
Watch out
Describing policies without linking them back to the socially optimum level of emissions.
