THE CORE PRINCIPLE — WHAT EVALUATION ACTUALLY IS
Evaluation is NOT:
- Adding more reasons the argument is correct
- Adding another KAA point from the other side
- Writing "however, it depends on many factors"
- Restating the analysis with hedging language ("may", "could", "might")
Evaluation IS:
- Reducing confidence in the main argument through a specific challenge
- Identifying the condition under which the argument fails or is limited
- Weighing the significance of competing arguments
- Making an informed conditional judgement about the likely outcome
The test before every evaluation sentence:
"Does this REDUCE confidence in my main argument? If no → it is not evaluation. Write it differently."
The Level 3 evaluation gatekeeper (from every examiner report):
"An informed judgement is needed in order to gain a Level 3 evaluation mark. Candidates who failed to provide a conditional judgement were limited to Level 2."
One unconditional conclusion anywhere in the evaluation band = Level 2 maximum. No exceptions.
THE CONDITION FORMULA — MANDATORY FOR LEVEL 3
Every evaluation move must end with an explicit condition. The condition tells the examiner what determines whether the argument holds or fails.
The condition sentence structure:
"This [effect / argument / policy] is [effective / limited / reversed] only if [condition].
If [alternative condition], [alternative outcome] — making [argument] [less/more] significant."
Approved condition-signalling phrases:
- "only if..."
- "provided that..."
- "depends on whether..."
- "conditional on..."
- "this holds only when..."
- "the extent to which this applies depends on..."
- "this argument is strongest when [condition] and weakest when [alternative]"
THE 12 EVALUATION MOVES — WITH FULL MECHANISM AND CONDITION
MOVE 1 — Time Lag
What it challenges: The immediate effectiveness of any policy When to use: Fiscal policy, monetary policy, supply-side policy, any intervention
Full evaluation paragraph: "However, [policy] is subject to significant transmission lags that limit its short-run effectiveness. The recognition lag (identifying the need for intervention), implementation lag (passing legislation or changing rates), and impact lag (waiting for the mechanism to transmit through the economy) can collectively span 12–24 months for fiscal policy and 6–18 months for monetary policy. In the interim, the economic conditions that justified the policy may have changed — the recession may have self-corrected, or inflationary pressure may have intensified — meaning the intervention arrives procyclically rather than countercyclically. This argument holds only if the time lag is longer than the economic cycle phase being targeted — if the lag is short relative to the cycle, the policy remains effective."
Compact version (for 8-mark Examine): "However, [policy] involves significant time lags before taking effect. By the time the mechanism transmits through the economy, the original conditions may have changed — the policy may arrive too late to prevent recession or may fuel inflation if the cycle has already turned. This effect is most limited when the lag is short relative to the economic cycle — a condition that varies by policy type and economy."
MOVE 2 — Magnitude / Size Dependency
What it challenges: The scale of the claimed effect When to use: Multiplier arguments, exchange rate effects, price elasticity questions
Full evaluation paragraph: "However, the magnitude of [effect] depends critically on [variable] — and the extract context suggests this may be smaller than the mechanism implies. For example, the multiplier effect depends on the MPC: in an open economy with high marginal propensity to import (MPM) and high marginal propensity to tax (MPT), the multiplier may be close to 1 — meaning the fiscal injection generates little amplified income growth. Similarly, the current account improvement from depreciation depends on PED — if exports are price inelastic (branded goods, essential commodities), export revenue may not rise proportionally to the price fall. This argument is most convincing only if [specific condition from extract] — which the data [supports / does not clearly support]."
Compact version: "However, the magnitude of [effect] depends on [variable]. In Country X, where [extract data], the [multiplier / elasticity / transmission] may be weaker than the mechanism implies — limiting the actual impact on [outcome]. This effect holds only if [condition]."
MOVE 3 — Competing Objective Conflict
What it challenges: The net benefit of achieving one objective at another's expense When to use: Any policy where achieving one objective worsens another (Phillips curve, growth-inflation, current account-growth)
Full evaluation paragraph: "However, achieving [objective 1] through [mechanism] creates a direct conflict with [objective 2]. [Expansionary policy / currency depreciation / wage-cutting supply-side measures] that [achieves objective 1] simultaneously [mechanism by which objective 2 worsens]. Policymakers cannot simultaneously achieve both objectives through the same instrument — the improvement in [objective 1] is only available at the cost of [objective 2] deterioration. In Country X, where [extract data about objective 2], this conflict is particularly significant. The argument that [policy] is effective therefore holds only if [objective 1] is weighted more highly than [objective 2] in the policymaker's objective function — a normative judgement that the question cannot resolve on economic grounds alone."
Most common conflicts to deploy:
- Inflation ↔ Unemployment (Phillips curve)
- Growth ↔ Inflation (positive output gap)
- Growth ↔ Current account (higher income → higher imports)
- Inflation control ↔ Budget deficit (contractionary policy reduces tax revenues)
- Full employment ↔ Price stability (near NAIRU, wage pressure)
MOVE 4 — Crowding Out
What it challenges: Expansionary fiscal policy When to use: Any question about government spending increases
Full evaluation paragraph: "However, expansionary fiscal policy financed through government borrowing may crowd out private sector investment — partially or fully offsetting the intended AD stimulus. As the government increases its demand for loanable funds, competition for credit in financial markets rises, driving up the market interest rate. Higher rates increase the cost of private sector borrowing, reducing the return on investment projects and causing firms to postpone or cancel capital expenditure (I falls). If crowding out is complete — where the fall in I exactly matches the rise in G — the net effect on AD is zero, making the fiscal expansion entirely ineffective. This argument is most powerful only if the economy is at full employment (when competition for credit is most intense) — at significant spare capacity, crowding out is less severe as the supply of loanable funds is more elastic."
MOVE 5 — Liquidity Trap / Zero Lower Bound
What it challenges: Monetary policy effectiveness When to use: Questions about interest rate policy, monetary stimulus, when base rate is near zero
Full evaluation paragraph: "However, the effectiveness of interest rate cuts depends critically on the proximity to the zero lower bound. When the base rate approaches zero, conventional monetary policy loses its primary transmission mechanism — further cuts are technically impossible, and the incentive for banks to lend rather than hold reserves diminishes as the return on lending falls to near zero. Even if rates are cut, if consumer and business confidence is severely depressed, the fall in borrowing costs may not stimulate credit demand — as occurred in Japan's 'lost decades,' where decades of near-zero rates failed to generate sustained demand recovery. In Country X, where the base rate stands at [X]%, [there is / is limited] scope for further conventional rate reductions. This monetary policy argument therefore holds only if the base rate has meaningful room to fall — which the extract [does / does not] suggest."
MOVE 6 — Supply-Side Constraint on Demand Policy
What it challenges: Demand-side policy effectiveness when structural problems exist When to use: Any question where demand stimulus is proposed in an economy with structural issues
Full evaluation paragraph: "However, the effectiveness of demand-side policy in reducing unemployment depends on the nature of unemployment. If a significant portion of unemployment is structural — arising from skills mismatches, geographic immobility, or industrial restructuring — then expansionary fiscal or monetary policy that raises AD will encounter supply-side bottlenecks before returning to full employment. Firms seeking to expand output in the face of excess demand will find that available workers lack the required skills, generating wage inflation in skilled sectors while structural unemployment persists in declining industries. Demand-side policy therefore risks creating inflationary pressure rather than employment growth if structural unemployment is significant. This argument holds only if structural unemployment is a meaningful share of total unemployment in Country X — which the extract [suggests / does not clearly indicate] through [data / absence of retraining references]."
MOVE 7 — Expectations and Confidence
What it challenges: Any policy that depends on changing household or firm behaviour When to use: Consumer confidence questions, fiscal stimulus, QE effectiveness, supply-side credibility
Full evaluation paragraph: "However, the effectiveness of [policy] depends critically on whether it shifts the expectations and confidence of households and firms in the intended direction. If the private sector believes [policy] is unsustainable, will be reversed, or is insufficient to address underlying problems, they may not respond as the mechanism predicts. For example, if households anticipate future tax rises to finance current government borrowing, they may increase precautionary savings (Ricardian equivalence) rather than increasing consumption — nullifying the fiscal multiplier. Similarly, if business confidence remains depressed by non-economic factors — political uncertainty, regulatory risk, or global conditions — lower interest rates may not stimulate investment regardless of the rate level. This mechanism holds only if confidence channels are sufficiently strong — a condition that varies by institutional context and cannot be determined from interest rate data alone."
MOVE 8 — Marshall-Lerner / J-Curve (Exchange Rate)
What it challenges: The current account improvement from currency depreciation When to use: Any question involving exchange rate changes and trade
Full evaluation paragraph: "However, the improvement in the current account following depreciation is conditional on the Marshall-Lerner condition being satisfied — that the combined price elasticity of demand for exports and imports exceeds 1 (PEDₓ + PED_m > 1). In the short run, trade contracts are pre-agreed at previous prices, and import and export volumes adjust slowly — meaning the J-curve effect initially worsens the current account as import costs rise in domestic currency faster than export volumes grow. Only in the medium to long run, as quantities adjust to price signals, does the current account improve. In Country X, the extent of improvement therefore depends on the price elasticities of its specific export basket: if exports are inelastic branded goods or essential commodities, the price advantage of depreciation generates limited volume increases. This argument holds only if the Marshall-Lerner condition is met and sufficient adjustment time has elapsed — neither of which the extract confirms."
MOVE 9 — Fiscal Sustainability / Debt Constraint
What it challenges: Expansionary fiscal policy when government debt is high When to use: Questions about fiscal stimulus in indebted economies
Full evaluation paragraph: "However, the effectiveness of expansionary fiscal policy is constrained by the government's fiscal position. If government debt as a proportion of GDP is already elevated — as in Country X where debt stands at [X]% of GDP — financial markets may demand higher risk premiums on government bonds as debt rises further. Higher bond yields raise the cost of all government borrowing, potentially crowding out private investment and consuming a larger share of government revenue in debt servicing — reducing the net expansionary impact of the fiscal stimulus. In extreme cases, rising sovereign risk premiums can trigger a self-reinforcing debt spiral. This argument is most relevant only if Country X's debt-to-GDP ratio is above the threshold at which markets begin pricing in fiscal risk — typically considered to be above 90–100% of GDP, though this varies by country and currency."
MOVE 10 — Ricardian Equivalence
What it challenges: The consumption boost from tax cuts or deficit-financed spending When to use: Any question about fiscal policy effectiveness through consumer spending
Full evaluation paragraph: "However, if households are forward-looking — anticipating that deficit-financed tax cuts today imply higher taxes in the future to service government debt — they may respond to fiscal stimulus by increasing savings rather than consumption. This Ricardian equivalence argument suggests that rational households treat government borrowing as deferred taxation, reducing current consumption to prepare for the future tax burden — leaving AD and real GDP unchanged despite the fiscal intervention. In practice, full Ricardian equivalence is unlikely, as not all households have the financial literacy, time horizon, or ability to borrow and save that the theory requires. However, partial equivalence — where some households increase saving in response to fiscal stimulus — reduces the effective multiplier below its theoretical maximum. This effect is most limiting only if households are highly forward-looking and liquidity-unconstrained — conditions more likely in higher-income economies."
MOVE 11 — Structural vs Cyclical Diagnosis
What it challenges: Policy recommendations that misidentify the source of the problem When to use: Unemployment questions, fiscal deficit questions, inflation questions
Full evaluation paragraph: "However, the appropriateness of [demand-side / supply-side] policy depends critically on correctly diagnosing whether the problem is cyclical or structural in nature. If unemployment in Country X is primarily structural — arising from technological displacement or deindustrialisation — then expansionary demand-side policy will generate inflationary wage pressure in high-skill sectors without reducing structural unemployment in declining industries. Conversely, if a persistent fiscal deficit is structural (reflecting an underlying spending-revenue imbalance) rather than cyclical (reflecting temporarily low tax revenues during recession), supply-side reforms to long-run growth are required rather than short-run demand management. Misdiagnosis leads to policy that is not only ineffective but potentially counterproductive. This argument holds only if the correct diagnosis can be made — which requires data on the composition of unemployment and the structural versus cyclical fiscal balance that the extract may not provide."
MOVE 12 — International / Global Conditions Constraint
What it challenges: Any domestic policy in an open economy When to use: Export-dependent economies, exchange rate questions, global recession contexts
Full evaluation paragraph: "However, the effectiveness of domestic [policy] is constrained by global economic conditions that lie outside the domestic policymaker's control. If Country X's trading partners are simultaneously experiencing recession, demand for its exports will fall regardless of domestic price competitiveness — meaning neither depreciation nor fiscal stimulus can fully offset the external demand shock. In an open economy with a high trade-to-GDP ratio, external conditions can dominate domestic policy effects: global interest rate movements, commodity price volatility, and trading partner growth rates all influence domestic AD independently of domestic policy choices. This argument is most significant only if Country X has a high degree of trade openness — where the external sector accounts for a substantial share of GDP — a condition that is [evident / unclear] from the extract."
