Balance of Payments and Exchange Rates
How international transactions are recorded and how exchange-rate determination and change affect trade, inflation, activity and policy.
How to study A-level Economics
Define the issue and affected agents, choose an appropriate model, build the causal chain with data, then evaluate assumptions, trade-offs and alternatives before judging.
Core concepts
Concept 1
The balance of payments records transactions between residents of an economy and the rest of the world under defined accounts.
Exam cue: Identify the relevant balance-of-payments component and direction of the flow.
Concept 2
Exchange rates respond to currency demand and supply under institutional arrangements that can vary.
Exam cue: Trace which event changes demand or supply for a currency and label the new equilibrium.
Concept 3
Depreciation or appreciation affects import prices, export competitiveness, incomes and balances with time lags and elasticity conditions.
Exam cue: Evaluate exchange-rate effects using pass-through, elasticities, contracts, capacity and policy response.
