For Cambridge 9708, start by identifying the missing social cost or benefit. Then use the diagram or chain of reasoning to explain over- or under-allocation before judging a policy response.
Resource allocation: explain what prices do — and where they fall short
Economic systems answer what to produce, how to produce and for whom to produce. In an exam response, link the method of allocation to incentives, information, equity and efficiency.
Circular flow of income: trace where spending enters and leaves the economy
A circular-flow answer is strongest when it follows the money: identify the injection or leakage, explain the effect on aggregate demand and then qualify the likely impact on output, employment and prices.
Protectionism: explain the barrier, then judge the trade-off
Do not simply list advantages and disadvantages of protectionism. Explain the mechanism by which a tariff, quota or subsidy changes prices, quantities and incentives — then evaluate the wider effects.
Market structures: compare behaviour, outcomes and the case for intervention
A useful comparison of market structures goes beyond definitions. Link the number of firms and barriers to entry to price, output, efficiency, innovation and consumer choice.
Price elasticity of demand: calculate, classify, then apply
PED questions reward more than a formula. Calculate the coefficient, interpret what it means for a firm or government, and explain why responsiveness may change over time.
Inflation: identify the pressure before choosing the policy
Inflation is a sustained rise in the general price level. Strong answers separate demand-pull pressure from cost-push pressure and judge policies by their likely trade-offs.
Unemployment: diagnose the type, then match the response
For 9708, avoid treating unemployment as one problem. Explain why labour demand or labour-market matching has failed, then evaluate whether a demand-side or supply-side response fits.
Monetary policy: trace the transmission, then test its limits
Interest-rate questions are about mechanisms. Explain how a central-bank decision affects borrowing, saving, investment, exchange rates and aggregate demand before claiming a macroeconomic outcome.
Exchange rates: separate the price effect from the quantity response
A depreciation does not automatically improve the current account. Explain who faces higher or lower prices, then use elasticities, capacity and time to evaluate the eventual outcome.
