OCR A-Level Economics Past Papers & Mark Schemes

OCR Economics examiners consistently report that poor diagram work is the single biggest source of lost marks. A diagram must have: correctly labelled axes (Price on Y-axis, Quantity on X-axis for supply-demand), clearly labelled curves (S, D, S₁, D₁ as appropriate), equilibrium points marked, and the shift or movement clearly shown with arrows. A diagram that illustrates your written analysis earns additional marks; a poorly drawn or unlabelled diagram can actually lose you marks if it contradicts your text. Chain-of-reasoning analysis is what OCR calls the structured logical progression from cause to effect. For a question about the impact of a rise in interest rates: higher interest rates → increased cost of borrowing → reduced consumer spending and business investment → fall in aggregate demand → downward pressure on inflation → but potentially higher unemployment. Each link in the chain must be explicit — examiners cannot award marks for implied connections. The Themes in Economics paper (Paper 3) requires you to connect micro and macro analysis. Practise answering questions that bridge both areas: How does market failure (micro) affect economic growth (macro)? How does fiscal policy (macro) affect market competition (micro)? How does globalisation (macro) affect labour market structures (micro)? These connections are not made in many textbooks, so you need to practise them deliberately. Evaluation in economics means assessing the likely effectiveness of a policy or the strength of an argument. The strongest evaluations consider: the time frame (short-run vs long-run effects), the assumptions underlying the analysis (ceteris paribus may not hold), the magnitude of the effect (a small tax change versus a large one), and the opportunity cost of the policy. Simply stating 'it depends' is not evaluation — you must specify what it depends on and why that matters.
