This topic covers the interaction of markets, focusing on how demand and supply interact to determine market equilibrium and disequilibrium, the role of ceteris paribus, and the impact of changes in one market on related markets.
The balance of payments (BoP) is a record of all economic transactions between residents of a country and the rest of the world over a period, typically a year. It is divided into two main accounts: the current account and the financial/capital account. The current account records trade in goods (visible trade) and services (invisible trade), as well as income flows (e.g., profits, dividends) and current transfers (e.g., foreign aid). The financial account records cross-border investments, such as foreign direct investment (FDI), portfolio investment (shares and bonds), and changes in reserve assets. For OCR A-Level Economics, understanding the BoP is crucial because it reflects a country's economic health and its international competitiveness.
The BoP must always balance in an accounting sense—any surplus or deficit on the current account is exactly offset by a corresponding deficit or surplus on the financial/capital account. However, a persistent current account deficit may signal underlying problems, such as a lack of competitiveness or over-reliance on foreign capital. Conversely, a persistent surplus might indicate strong export performance but could also lead to trade tensions. Students should analyse the causes and consequences of imbalances, including the role of exchange rates, government policies, and global economic conditions. The BoP is closely linked to other macroeconomic objectives, such as economic growth, inflation, and employment.
In the OCR A-Level specification, the BoP is part of the 'International Trade and Globalisation' topic. You will be expected to interpret BoP data, evaluate policies to correct imbalances (e.g., expenditure-switching vs. expenditure-reducing policies), and discuss the sustainability of deficits or surpluses. Real-world examples, such as the UK's persistent current account deficit or China's surplus, are often used in exam questions. Mastering this topic will help you understand broader issues like global imbalances, protectionism, and the impact of Brexit on the UK's trade patterns.
