01Model
Build the economic model
The balance of payments records transactions with the rest of the world. A current-account balance is mirrored by capital/financial flows and reserve changes under accounting conventions.
For balance of payments, state the relationship between current account and the relevant agents, then identify the ceteris-paribus conditions. The model is a disciplined simplification, not a complete description of reality.
- Define the central variables precisely.
- Identify the agents making decisions.
- State what is held constant and why that matters.
02Evidence
Apply evidence and data
An economy runs a current-account deficit financed by inward investment while importing capital equipment.
Application in balance of payments means using scale, direction, timing and source to alter the argument. Explain how the evidence changes the mechanism instead of merely naming the context or copying a figure.
- Check units, dates and whether values are nominal or real.
- Separate correlation from a supported causal inference.
- Identify winners, losers and the appropriate counterfactual.
03Analyse
Develop the mechanism
Domestic saving-investment, competitiveness or demand changes → trade and income flows change → financing flows and exchange pressure respond → sustainability depends on use and confidence.
Carry this balance of payments chain far enough to answer the question: identify the agent's response, the resulting market or macroeconomic change and why the outcome matters.
- Explain each arrow in the chain.
- Use the diagram or calculation in the written analysis.
- Distinguish short-run adjustment from longer-run response.
04Evaluate
Evaluate assumptions and magnitude
A deficit is not inherently harmful: its risk depends on financing stability, productivity effect, currency, debt maturity and ability to adjust.
Evaluation of balance of payments should change confidence in the result. Test elasticity, time lags, scale, incentives, distribution and unintended effects rather than adding a generic “however”.
- Which assumption is most fragile?
- Would a different elasticity reverse or only weaken the result?
- What evidence could change the judgement?
05Judge
Reach an informed judgement
For balance of payments, choose the argument with the greatest contextual importance and explain why it outweighs the alternative. State the conditions under which it holds rather than repeating the introduction.
The opportunity cost and distributional effect of current account matter. Political preferences may affect objectives, but the exam judgement must rest on transparent assumptions and evidence rather than ideology.
- Answer the exact command and scope.
- Rank the decisive factors.
- State a condition, timeframe and possible reason to revise the conclusion.
From theory to a testable claim
The balance of payments records transactions with the rest of the world. A current-account balance is mirrored by capital/financial flows and reserve changes under accounting conventions.
Applied taskAn economy runs a current-account deficit financed by inward investment while importing capital equipment.
Causal chain
Domestic saving-investment, competitiveness or demand changes → trade and income flows change → financing flows and exchange pressure respond → sustainability depends on use and confidence.
Applied taskRewrite the balance of payments chain with one piece of numerical or contextual evidence at the link where it changes the expected magnitude.
Evaluation that does work
A deficit is not inherently harmful: its risk depends on financing stability, productivity effect, currency, debt maturity and ability to adjust.
Applied taskExplain whether this consideration weakens, delays, redistributes or reverses the predicted balance of payments outcome.
