Verdict on Paper Difficulty

The January 2024 International AS Economics series presented a very balanced assessment across both Unit 1 (Markets and Market Failure) and Unit 2 (The National Economy). Overall, the papers rate as a 3.5 out of 5 in terms of difficulty, providing an accessible pathway for prepared candidates while integrating rigorous evaluative essays to stretch top-tier students. Unit 1 focused on contemporary environmental challenges, using plastic waste as an anchor context. Unit 2 tested core macroeconomic aggregates with a strong emphasis on fiscal structures and development policy.

Where the Marks are Won and Lost

High marks were secured by students who mastered the precise micro-foundations of market failures and macroeconomic indicators. Specifically:

  • Precise Definitions: Scoring full marks on definitions of free market economy and unemployment rate requires specific terminology rather than colloquial explanations.
  • Calculation Precision: The 4-mark PED calculation in Unit 1 required careful negative sign inclusion (\( -0.21 \)) and exact rounding.
  • Clear Diagrammatic Analysis: In Unit 1 Q19, candidates who accurately contrasted the marginal private benefit (\( MPB \)) and marginal social benefit (\( MSB \)) curves to illustrate overconsumption won major marks. In Unit 2, showing a leftward shift in short-run aggregate supply (\( SRAS \)) with price level rising was critical.

Examiner Pitfalls and Misconceptions

A common error was the confusion of disinflation (a reduction in the rate of inflation) with deflation (a sustained decrease in the average price level). Additionally, in the essay questions, many candidates failed to clearly separate national debt from the annual government budget deficit, which limited their analytical depth in Unit 2 Q20. Many students also overlooked the significance of negative signs in elasticities, failing to indicate negative values for PED.

Strategies and Predictions

To prepare for future series, students must practice constructing complete economic transmission chains. Avoid jumping directly from policy to economic growth without explaining intermediate steps such as productivity gains, cost changes, and international competitiveness. Given the patterns of this paper, we predict that globalisation, monetary policy tools (such as interest rate manipulation or exchange rate targets), and labour market interventions are highly likely to feature prominently in upcoming examinations.
