1–20 Market structure and policy mechanisms
- deadweight loss — a loss of total surplus relative to an efficient allocation. identify the deadweight loss from underproduction.
- price ceiling — a legal maximum price. a binding price ceiling can create excess demand.
- price floor — a legal minimum price. a binding price floor can create excess supply.
- tradable permit — an authorisation that can be exchanged and allows a specified activity. tradable permits place a price on emissions.
- internalise — bring an external cost or benefit into a decision-maker’s incentives. a charge may internalise an external cost.
- excludability — the ability to prevent people from using a good. excludability affects how a service can be financed.
- rivalry — the extent to which one person’s use reduces what others can use. rivalry increases when a road is congested.
- free rider — someone who benefits without contributing to the cost. a free rider may still benefit from street lighting.
- moral hazard — a change in behaviour after protection alters the cost of taking risks. insurance can create moral hazard.
- adverse selection — a distortion in who participates when one side has hidden information. adverse selection can change the mix of people insured.
- sunk cost — a cost already incurred that cannot be recovered. sunk costs may deter market entry.
- economies of scale — falls in long-run average cost as output expands. economies of scale can favour larger firms.
- normal profit — the minimum return needed to keep resources in their present use. normal profit is included in economic cost.
- supernormal profit — profit above normal profit. barriers can help sustain supernormal profit.
- price discrimination — charging different prices for comparable units when differences are not explained by cost. price discrimination requires some ability to separate customers.
- derived demand — demand for an input arising from demand for its output. demand for labour is derived from demand for its product.
- marginal revenue — the addition to total revenue from selling an extra unit. a firm compares marginal revenue with marginal cost.
- transfer payment — a payment made without receiving current goods or services in return. a transfer payment can change disposable income.
- trade creation — a shift to a lower-cost partner producer following trade integration. trade creation can lower production costs.
- trade diversion — a shift to a higher-cost partner producer because of preferential treatment. trade diversion can offset gains from integration.
21–40 Microeconomic analysis
- scarcity — limited resources in relation to wants. scarcity requires a choice.
- opportunity cost — the value of the best alternative forgone. evaluate the opportunity cost of a subsidy.
- elasticity — responsiveness of one variable to a change in another. price elasticity affects the fall in quantity demanded.
- inelastic — relatively unresponsive to a change in a specified variable. inelastic demand for a necessary input.
- equilibrium — a position where opposing forces balance in the model. a new market equilibrium.
- surplus — an excess or a gain beyond a reference point, depending on context. a fall in consumer surplus.
- shortage — an excess of quantity demanded over quantity supplied at a given price. a binding ceiling can create a shortage.
- marginal — relating to the next unit or a small additional change. compare marginal social cost with marginal social benefit.
- externality — a cost or benefit affecting a third party outside the transaction. congestion can create a negative externality.
- incidence — the distribution of an economic burden or benefit. the incidence of a tax depends on relative elasticities.
- subsidy — financial assistance that can change incentives or costs. a subsidy reduces the effective cost of an activity.
- rationing — allocating a limited quantity among competing users. price rationing allocates available supply.
- monopoly — a market with a single seller, or dominant market power in relevant usage. evaluate the consequences of monopoly power.
- monopsony — a market with a single buyer, or dominant buyer power in relevant usage. a firm with monopsony power can influence wages.
- oligopoly — a market dominated by a few firms. strategic interaction in an oligopoly.
- contestability — the extent to which entry and exit can discipline firms. contestability depends partly on sunk costs.
- barrier — an obstacle that makes entry or action difficult. a barrier to entry protects incumbents.
- welfare — economic wellbeing, often assessed through benefits and costs. evaluate the net welfare effect.
- allocative efficiency — allocation where marginal social benefit equals marginal social cost in the standard framework. the tax may move output toward allocative efficiency.
- productive efficiency — production at the lowest attainable average cost for the relevant output or at minimum average cost in the standard firm diagram. distinguish productive efficiency from higher output alone.
41–60 Macroeconomic analysis
- inflation — a sustained rise in the general price level. distinguish inflation from an individual price rise.
- disinflation — a fall in the inflation rate while prices may still be rising. disinflation reduces the rate of price increase.
- deflation — a sustained fall in the general price level. deflation can increase the real burden of debt.
- unemployment — the condition of being without work while available for and seeking it under the standard measure. cyclical unemployment can rise during a downturn.
- productivity — output per unit of input. higher labour productivity can reduce unit costs.
- aggregate demand — planned total expenditure on domestically produced output at a given price level. higher investment can raise aggregate demand.
- aggregate supply — total output firms are willing to produce at a given price level. higher input costs can reduce short-run aggregate supply.
- output gap — the difference between actual and potential output. a negative output gap indicates spare capacity.
- multiplier — the ratio of the eventual change in national income to the initial change in an injection. a larger marginal propensity to import can reduce the multiplier.
- leakage — a withdrawal from the circular flow, such as saving, taxation or imports. higher imports increase a leakage.
- injection — spending entering the circular flow through investment, government spending or exports. a rise in exports is an injection.
- fiscal policy — use of government spending and taxation to influence the economy. an expansionary fiscal policy can raise demand.
- monetary policy — central-bank action influencing monetary and financial conditions. monetary policy operates through several channels.
- transmission — the process through which a policy change affects the economy. the transmission from rates to investment can take time.
- exchange rate — the price of one currency in terms of another. the exchange rate can affect import prices.
- depreciation — a fall in the value of a currency under a floating exchange-rate system. depreciation can raise the domestic price of imports.
- current account — the balance-of-payments account recording trade and primary and secondary income flows. consider the effect on the current account.
- crowding out — a reduction in private spending associated with increased public spending or borrowing. crowding out may limit the rise in investment.
- capacity — the level of output an economy or producer can sustain with available resources. spare capacity can affect the inflation response.

How the Cambridge 9708 essay sections work
In both papers, Section A is compulsory. In Section B, choose one question from two mainly on microeconomics. In Section C, choose one from two mainly on macroeconomics. Paper 2 essay questions have two parts. Paper 4 essay questions are unstructured and have no parts. Practise the structure for the paper you are taking.
Cambridge assesses knowledge and understanding, analysis and evaluation. In an explanation, use the model to trace what happens and why. For evaluation, test assumptions and weigh outcomes against a criterion. Clearly labelled diagrams can help when the question or mechanism calls for one. Explain the change in words as well.

Worked microeconomics example on a price ceiling
Original practice question. Discuss whether imposing a maximum rent is likely to improve access to rented housing. Start by identifying the market and what access means. A rent below the market equilibrium is a binding ceiling in the simple model.
A binding ceiling can lower the rent paid by tenants who obtain a dwelling under the rule. At that price, quantity demanded exceeds quantity supplied in the standard diagram. A lower listed rent can therefore improve affordability for some households while leaving others unable to find a dwelling. The size of the shortage depends in part on the responsiveness of tenants and landlords. In the longer run, a weak incentive to add units could make access harder for new tenants if other policies do not expand supply.
The paragraph distinguishes affordability for successful applicants from the quantity available. A fuller evaluation could examine eligibility, exemptions, the time horizon and a policy that increases housing supply. Keep the example hypothetical unless you have checked the actual design and evidence for a real scheme.

Worked macroeconomics example on depreciation
Consider whether depreciation will improve the current account. A weaker currency can make exports cheaper to overseas buyers and imports more expensive in domestic currency, depending on how firms set prices. The quantity responses may be small at first because contracts and consumption patterns take time to change. A change in relative prices does not establish that export revenue will rise by more than import spending changes.
Make the claim conditional on elasticities, time and productive capacity. A firm may receive more orders but be unable to expand output quickly. More expensive imported inputs could also affect its costs. Compare an economy with spare capacity and responsive demand against one facing supply constraints. Use that comparison to explain where improvement is more likely.

How to fence a 9708 economic term
1. Base. The ceiling can create a shortage. 2. Detail. A rent ceiling below equilibrium can create a shortage of rented homes. 3. Tone. A binding rent ceiling may improve affordability for tenants who secure a dwelling. 4. Logic. Since quantity demanded can exceed quantity supplied at the controlled rent, a lower price does not ensure every applicant can obtain housing. 5. Transfer. A binding maximum price can create excess demand in another market where supply cannot quickly expand.
Distinguish a shortage from scarcity. Scarcity describes limited resources relative to wants. A shortage describes excess demand at a given price. Draw a diagram with a binding ceiling and check that the quantities you label correspond to the controlled price.

Practice and frequently asked questions
Do I write both a microeconomics and a macroeconomics essay? Yes, in Papers 2 and 4. Do Paper 4 essays have two parts? The 2026–2028 syllabus specifies unstructured questions without parts. What is a strong evaluation? It explains which assumptions, stakeholders or time horizons change the likely result and why.
For a timed attempt, mark the command and outcome first. If the question asks about unemployment, make sure your analysis does more than explain an effect on inflation. Finish by stating the extent to which the proposed policy meets the objective under the conditions you discussed.
Practice workshop
Read the two parts separately
In Paper 2, write a short note beside each part identifying the command and outcome. The same broad issue can ask first for a mechanism and then for a judgement. Do not spend the first answer evaluating a policy whose effects the question asks you to explain. Carry over a definition only if it helps the second answer.
Build a Paper 4 plan without subquestions
Begin with the proposition in the question. Decide what model helps analyse it and which assumption is most important. Give one paragraph to the mechanism and another to a competing effect or condition. Use the conclusion to compare the effects. The unstructured format lets you organise the argument around the issue rather than reconstructing Paper 2 parts.
Label the ceiling diagram from the question
For rent control, label the axes with rent and quantity of rental housing. Identify the equilibrium before intervention and place a binding ceiling below it. Locate both quantities at the controlled price. Explain how the diagram shows excess demand and why the benefit of a lower price depends on securing a dwelling.
Make an efficiency claim specific
If an answer says a policy improves efficiency, identify which inefficiency it addresses. A charge can change incentives related to external cost. A reform that lowers production costs addresses a different issue. Explain whether your benchmark concerns allocation, cost of production or improvements over time. Then show why the chosen benchmark matters to the prompt.
Test a macro claim across two time horizons
For depreciation, compare the immediate effect on prices and contract values with the later response of quantities. Then ask what happens if domestic firms cannot expand supply. Write a conclusion that identifies the condition under which the effect on the current account is likely to be stronger. Keep changes in the trade balance distinct from other current-account components.
Compare policy targets
Suppose one policy aims to make rent affordable now and another to increase supply over several years. Identify how the same household might be affected at different times. A comparison becomes useful when you explain which result matters most under the question’s wording. Add a third paragraph only if it introduces a distinct effect.
Use data response evidence deliberately
The compulsory section uses provided material. Read labels, units and dates before making a claim from a figure. Quote or describe the specific detail that helps answer the question, then connect it to an economic mechanism. If the figure shows one market or period, keep the claim within that scope.
Repair a conclusion that only restates the debate
Replace there are good and bad effects with a judgement about a named objective. For example, distinguish improving affordability for existing tenants from increasing access for people seeking a home. State which effect is likely under the conditions you described. A concise condition is more useful than repeating every earlier point.
Practise selecting a relevant diagram
Choose a market failure question and list two diagrams you know. Decide which one actually represents the problem in the prompt. Draw it once, then explain its main change in three sentences. If the diagram adds no information beyond the definition, consider whether a more appropriate model or a clearer application would help.
Track what each assumption does
In a margin note, record one assumption about consumers, one about firms and one about time. Next to each, write what would change if it were false. Use the assumption that materially changes the answer. This lets evaluation develop from the analysis rather than appearing as a list of generic limitations.
