New Zealand Scholarship Economics common mistakes
New Zealand Scholarship Economics · Understand the traps and how to avoid them.
Writing a descriptive essay that explains what happened in the resource or data set but never states an explicit judgement or thesis about the economic issue.
Scholarship markers reward sustained analytical argument rather than summary; many candidates are trained by internal assessment to 'cover content' and mistake breadth of description for depth of analysis, so they run out of space before committing to a position.
What to do instead
Before writing, draft a one-sentence thesis (e.g. 'The policy improves equity at an efficiency cost that is larger than the stated fiscal saving'). Open the essay with that thesis, and make every subsequent paragraph either support, qualify, or test it. After drafting, highlight each topic sentence and delete any paragraph that does not advance the thesis.
Using economic models (supply and demand, cost curves, Lorenz curve, multiplier) only as decoration: drawing or describing them but never using a shift, equilibrium change, or welfare area to drive the argument.
Candidates learn diagrams as recall items for externals and reproduce them without linking them to the specific question. Under time pressure, a diagram can feel like a safe way to show knowledge, so it is inserted rather than integrated.
What to do instead
For every diagram, write the mechanism in words alongside it: which curve shifts, why, what happens to price, quantity, and the relevant welfare or distributional measure, and what this implies for the question asked. If a diagram cannot be tied to a stated implication, remove it. Practise 'model-to-judgement' sentences: 'Because supply is inelastic, the incidence falls mainly on consumers, so the policy's redistributive aim is undermined.'
Treating 'evaluate' as 'list advantages and disadvantages' and ending with a fence-sitting conclusion such as 'it depends' or 'both sides have merit' without stating criteria or a conditional judgement.
Balanced-two-sides structure is a familiar and safe habit, and candidates fear that a firm judgement will be marked wrong if the examiner disagrees. They also lack explicit evaluative criteria to rank competing effects.
What to do instead
State the criteria in advance (magnitude, incidence, time horizon, distributional impact, uncertainty, feasibility) and then weigh the effects against them. Conclude with a conditional judgement: 'The policy is justified if the elasticity estimates are below X; otherwise the efficiency loss dominates.' This satisfies evaluation without pretending certainty.
Citing real-world examples or statistics vaguely or inaccurately (for example, 'inflation is currently high' or an invented figure) instead of using a specific, defensible illustration of the mechanism.
Candidates believe Scholarship requires extensive current-affairs knowledge and try to signal it with broad claims. Without verifiable figures they resort to generic statements, and under pressure they may fabricate numbers.
What to do instead
Use examples to illustrate a mechanism, not to prove a magnitude. Prefer a small number of well-understood cases (a named policy, a known market structure, a historical episode) and state the direction of the effect rather than an uncertain number. If a figure is uncertain, say 'roughly' and explain the reasoning behind the estimate; never invent precise statistics.
Ignoring the New Zealand context when the question is framed around it, and answering with generic textbook theory that could apply to any economy.
Candidates revise theory in the abstract and do not connect it to small, open, primary-exporting economy features such as a concentrated export base, imported inflation, a small labour market, or the role of the Reserve Bank's inflation targeting and the fiscal framework.
What to do instead
Build a short mental checklist of NZ-specific structural features (openness to trade, terms-of-trade shocks, housing and land markets, migration flows, concentration in some product markets, monetary policy transmission through a small financial system). Explicitly link at least one structural feature to the mechanism under discussion, and explain why it changes the standard prediction.
Confusing microeconomic efficiency concepts with equity or distributional concepts, or asserting that a policy is 'good' because it is efficient without acknowledging the trade-off.
The efficiency-equity distinction is often learned as definitions rather than as an analytical tension, so candidates collapse the two and make normative claims that are not supported by the model they are using.
What to do instead
For each policy, explicitly separate the efficiency question (total surplus, deadweight loss, productive and allocative efficiency) from the distributional question (who gains, who loses, incidence). State which criterion the question prioritises, and if there is a trade-off, quantify its direction and discuss whether a compensating policy could address the equity concern at lower efficiency cost.
Misapplying elasticity, incidence, or multiplier reasoning, for example assuming a tax is fully passed on to consumers regardless of relative elasticities, or adding up spending without accounting for leakages.
These are multi-step mechanisms that are easy to state in one direction and hard to apply under pressure. Candidates remember the conclusion ('taxes raise prices') but not the condition under which it holds.
What to do instead
Write the condition before the conclusion: 'The burden falls more on the side of the market that is less elastic.' Then apply it to the specific market and state the implication. For multipliers, always name the leakages (saving, taxation, imports) and explain how each reduces the eventual effect. Practise explaining the mechanism in two or three causal steps rather than asserting the result.
Running out of time or space because the essay is unstructured, with long introductions and no planning, so the strongest analytical points are never reached.
Scholarship essays demand substantial sustained writing under time constraints, and candidates who do not plan tend to spend disproportionate time on context and definition, leaving the evaluative core underdeveloped.
What to do instead
Allocate the first few minutes to a skeleton plan: thesis, three or four analytical moves, the model or evidence for each, and the conclusion. Keep definitions to one sentence each and place them where they are used rather than in a block at the start. Practise full timed essays so the pacing is rehearsed, and reserve time for a final check that the thesis is answered.
Presenting a single-cause explanation for a complex outcome, for example attributing inflation solely to money supply growth or unemployment solely to minimum wages, without considering alternative explanations.
Candidates want a clean argument and fear that acknowledging complexity weakens it. In practice, the ability to weigh competing explanations is exactly what distinguishes Scholarship-level analysis.
What to do instead
For each major claim, name at least one competing explanation or counter-mechanism and explain why the evidence favours one over the other. Use phrases that signal weighing ('the larger effect is likely to be... because...'), and explicitly state what evidence would change the conclusion. This demonstrates evaluative control rather than indecision.
Misreading the directive of the question, for example answering 'discuss the causes' with a policy recommendation, or ignoring a constraint such as 'using the data provided' or 'in the context of a small open economy'.
Under exam pressure candidates latch onto a familiar topic and write the essay they have rehearsed rather than the one asked, and they skim over qualifiers that change what counts as a relevant answer.
What to do instead
Underline the directive verb and every qualifier in the question before planning, and restate the task in one sentence in the plan. Check the final paragraph against that restatement to confirm every part of the question has been addressed. If a constraint is given, refer to it explicitly at least once in the body so the marker can see it has been used.
