These GCE A Level Economics 2016 spec topics consistently produce the lowest scores. Prioritise these in your revision.

Productivity — definition, measurement, and how to improve it
Examiners noted in 2023 that despite productivity appearing frequently on past papers, 'many candidates still appeared to have little idea what is meant by productivity'. In 2025, candidates who could link a rise in productivity to a shift in LRAS and trace impacts on macroeconomic objectives scored highly, but many became fixated on demand-pull inflation instead.
Affects: AS 2
!
Index numbers — reading, rebasing, and computing percentage change from an index
A recurring error across all three years in AS 2 and A2 2: candidates subtracted index values to get a 'percentage change', or used a deflator incorrectly. In 2024, index number questions had the lowest mean mark on the AS 2 paper, with many candidates leaving them blank. Examiners stated this should be 'a basic skill for A-Level economists'.
Affects: AS 2, A2 2
!
Balance of Payments — components, current account deficit financing, and terminology
Multiple errors every year: confusing the trade and fiscal deficit; believing the BoP does not need to balance; misunderstanding that a Current Account deficit requires a Financial Account surplus to finance it; and using outdated terminology ('Net Investment Income and Transfers') rather than 'Primary and Secondary Income'. Also, flagged in 2025: over 60% of candidates could not define Primary Income.
Affects: A2 2
!
Economic inactivity — definition, causes, and distinction from unemployment
In 2023, examiners stated it was 'disappointing' that candidates could not explain economic inactivity or its four main causes (full-time students, full-time carers, those unable to work due to disability/illness, and those in early retirement). Candidates wrongly assumed all economically inactive individuals were claiming benefits.
Affects: AS 2
!
Comparative advantage — post-specialisation production and mutually beneficial trade distribution
A persistent weakness in A2 2: candidates could identify which country had the comparative advantage but could not 'clearly show a mutually beneficial post trade distribution of goods' using the data. Many rehashed their identification answer or gave general theory rather than working through the example.
Affects: A2 2
!
PED and PES — applying elasticity concepts to price volatility and tax incidence
In 2024 (AS 1), 'only a few were able to accurately analyse the influence of these concepts on price volatility'. In 2025, candidates used the wrong elasticity figure (PED instead of XED) and failed to identify that a PED of -1.36 meant the producer would absorb the majority of a tax. Knowing elasticity definitions is not enough — candidates must apply them.
Affects: AS 1
!
Government failure — causes and likelihood, distinct from market failure solutions
In 2024 (AS 1), 'surprisingly few candidates discussed the possible causes of government failure and hence were unable to access marks in the Level 3 range'. Candidates provided examples of government intervention to correct market failure without addressing whether that intervention would itself fail.
Affects: AS 1
!
Diagrams for natural monopoly, price discrimination, and diseconomies of scale
Flagged across multiple years in A2 1: candidates could define these concepts but failed to apply them diagrammatically. Natural monopoly diagrams required showing the declining LRAC across the full market output. Price discrimination required separate diagrams for first, second, and third degree. Diseconomy of scale required the LRAC turning upward. Without accurate diagrams, analysis was capped below Level 3.
