What are the measures of economic performance in economics?

Economists use four macroeconomic indicators to judge how well an economy is performing. Each measure captures a different dimension of economic health, and governments typically aim to achieve strong GDP growth, low and stable inflation, low unemployment, and a sustainable balance of payments position simultaneously.

In the UK, the Office for National Statistics (ONS) publishes quarterly GDP figures, monthly inflation data via the Consumer Prices Index (CPI), and regular unemployment statistics. These figures directly influence Bank of England interest rate decisions and government fiscal policy, making them highly relevant to exam questions on policy responses.

No single measure tells the full story. High GDP growth may coincide with rising inflation or a widening current account deficit, creating policy conflicts. Examiners reward students who recognise these trade-offs and use data to support evaluation.

1. →(4 marks) Define GDP and explain one limitation of using it to measure economic performance.
2. →(8 marks) Explain two reasons why a government might prioritise reducing inflation over reducing unemployment.
3. →(12 marks) Analyse the possible causes of a current account deficit in the UK economy.
4. →(20 marks) Evaluate the view that GDP growth is the most important measure of economic performance for the UK government.
5. →(25 marks) Assess the extent to which low unemployment is compatible with low inflation in the UK economy.

• →Always define each measure precisely in your opening sentence — examiners award definition marks independently of the quality of your subsequent analysis.
• →Avoid treating GDP growth as automatically positive — high growth accompanied by rising inflation or a widening trade deficit demonstrates evaluative thinking that targets higher mark bands.
• →Include real UK data in your answers, such as referencing CPI inflation peaking above 11% in October 2022, to show applied knowledge and access top-level evaluation marks.
• →Show awareness of conflicts between the four measures, particularly the inflation-unemployment trade-off illustrated by the Phillips Curve, as this is a recurring theme in higher-tariff questions.
• →Define the difference between nominal and real GDP when answering questions about growth, since failing to distinguish between them is a common error that costs marks at every grade boundary.

Gross Domestic Product (GDP): The total monetary value of all goods and services produced within a country's borders over a given time period, typically measured quarterly or annually.

Inflation: A sustained rise in the general price level of goods and services in an economy, commonly measured in the UK using the Consumer Prices Index (CPI).

Unemployment: The number of people who are actively seeking work but are unable to find employment, measured in the UK by the Labour Force Survey (LFS) using the ILO definition.

Current Account Balance: A component of the balance of payments that records the value of trade in goods and services, income flows, and current transfers between a country and the rest of the world.

Real GDP: GDP that has been adjusted for inflation, allowing comparisons of actual output growth over time without distortion from rising price levels.

Macroeconomic Objectives: The key economic goals pursued by a government, typically including strong and sustainable GDP growth, low and stable inflation, low unemployment, and a satisfactory balance of payments position.
