What you'll learn
This revision guide covers the four main macroeconomic objectives that governments pursue and the key indicators used to measure economic performance. You'll learn how governments assess whether the economy is performing well, understand the targets they set, and be able to interpret economic data presented in WJEC exam questions.
Key terms and definitions
Gross Domestic Product (GDP) — the total value of all goods and services produced within a country's borders over a specific time period, usually one year
Inflation — a sustained rise in the general price level of goods and services in an economy over time, reducing the purchasing power of money
Unemployment — when people of working age who are actively seeking work cannot find jobs
Balance of payments — a record of all financial transactions between one country and the rest of the world over a given period
Economic growth — an increase in the productive capacity of an economy, measured by the rise in real GDP over time
Consumer Price Index (CPI) — the main measure of inflation in the UK, tracking the changing cost of a fixed basket of goods and services
Current account — a component of the balance of payments recording trade in goods and services, income flows, and transfers
Economic indicator — a statistic that provides information about the performance and health of an economy
Core concepts
The four main macroeconomic objectives
Governments aim to achieve four primary economic objectives simultaneously, though achieving all four creates challenges as they often conflict with each other.
Economic growth
The government seeks sustained increases in real GDP, meaning output grows faster than inflation. The UK typically targets 2-3% annual growth. Economic growth matters because it:
- Raises living standards through higher incomes
- Creates more jobs and reduces unemployment
- Generates additional tax revenue for public services
- Increases business confidence and investment
Real GDP strips out the effects of inflation to show genuine increases in output. If nominal GDP rises 5% but inflation is 3%, real GDP growth is approximately 2%.
Low and stable inflation
The UK government sets an inflation target of 2% per annum, measured by CPI. This target balances the benefits of price stability against the risk of deflation (falling prices). Moderate inflation is preferable because:
- It encourages spending rather than hoarding money
- It makes debt easier to repay over time
- It provides flexibility for wages and prices to adjust
- Very low inflation or deflation can trigger recession
The Bank of England independently controls monetary policy to hit this target. If inflation deviates more than 1% above or below the target, the Governor must write to the Chancellor explaining why.
Low unemployment
Governments aim to minimise unemployment whilst maintaining some frictional unemployment (people between jobs). The UK considers 3-5% unemployment relatively acceptable. Low unemployment is crucial because:
- Unemployed workers represent wasted productive resources
- Unemployment benefits cost the government money
- Lost output means lower tax revenues
- Unemployment causes poverty and social problems
The main UK measure is the Labour Force Survey (LFS), which counts people actively seeking work. The claimant count tracks those claiming unemployment benefits, usually producing a lower figure.
Balance of payments equilibrium
The government aims for a sustainable position on the current account of the balance of payments — ideally a small surplus or deficit no larger than 2-3% of GDP. The current account records:
- Trade in goods (visible trade) — exports minus imports of physical products
- Trade in services (invisible trade) — financial services, tourism, transport
- Income flows — profits, interest, and dividends from overseas investments
- Transfers — foreign aid, EU contributions (historically), remittances
A large current account deficit indicates a country imports more than it exports, borrowing from abroad to finance the gap. While not immediately harmful, persistent large deficits can undermine confidence in the economy.
Measuring economic growth
Real GDP and GDP per capita
GDP can be calculated three ways (all producing the same result):
- Output method — total value of goods and services produced
- Expenditure method — total spending on goods and services (C + I + G + X - M)
- Income method — total income earned from production (wages, profits, rent, interest)
GDP per capita divides total GDP by population size, giving average income per person. This provides a better comparison between countries of different sizes. For example, China has higher total GDP than the UK, but the UK has higher GDP per capita because it has a much smaller population.
Limitations of GDP as a measure
GDP has significant shortcomings as a welfare indicator:
- Excludes the informal economy and unpaid work (childcare, volunteering)
- Ignores income inequality — GDP may rise whilst most people are worse off
- Doesn't account for environmental damage or resource depletion
- Misses quality-of-life factors like leisure time, health, and safety
- Underground economy activity (cash-in-hand work) goes unrecorded
Measuring inflation
The Consumer Price Index
CPI tracks price changes for approximately 700 goods and services in a representative "basket," weighted by importance in household budgets. The Office for National Statistics (ONS) surveys 180,000 prices monthly across the UK.
The basket changes annually to reflect consumption patterns. Recent additions include streaming subscriptions and e-cigarettes; items removed include DVD players and satellite navigation systems.
Calculating inflation rates
If the CPI stands at 105 in Year 1 and 108 in Year 2, the inflation rate is:
(108 - 105) / 105 × 100 = 2.86%
The Retail Price Index (RPI)
The RPI is an older measure still used for adjusting pensions and rail fares. It includes housing costs like mortgage interest payments, which CPI excludes. RPI typically produces higher inflation figures than CPI.
Measuring unemployment
The Labour Force Survey
The LFS asks 40,000 households whether members are:
- Employed (working at least 1 hour per week for pay)
- Unemployed (not working but actively seeking work and available to start within two weeks)
- Economically inactive (not working and not seeking work — students, carers, retired, long-term sick)
The unemployment rate divides the number unemployed by the economically active population (employed plus unemployed), expressed as a percentage.
The claimant count
This records people claiming Jobseeker's Allowance or Universal Credit while looking for work. It undercounts true unemployment because:
- Some unemployed people don't qualify for benefits
- Partners of claimants may be unemployed but not counted
- Young people under 18 typically cannot claim
The claimant count updates monthly and provides faster data than the quarterly LFS.
Types of unemployment
- Structural unemployment — jobs lost permanently due to industry decline (coal mining, shipbuilding)
- Cyclical unemployment — jobs lost during recession when demand falls
- Frictional unemployment — short-term unemployment between jobs
- Seasonal unemployment — regular variations (agricultural workers, tourism)
Measuring the balance of payments
The current account structure
The current account has four components:
- Trade in goods — typically the UK's largest deficit (£130bn in recent years)
- Trade in services — usually a surplus (£90bn) from financial services, insurance, education
- Primary income — profits, interest, dividends from overseas investments (variable)
- Secondary income — transfers like foreign aid and EU contributions (deficit)
Interpreting current account positions
A current account deficit means net borrowing from abroad. The UK has run persistent deficits since 1998, peaking above 5% of GDP in 2016. Causes include:
- Strong pound making exports expensive
- High consumer demand for imports
- Decline in manufacturing industries
- Rising oil imports as North Sea production falls
A surplus indicates net lending to other countries. Germany consistently runs large surpluses (7-8% of GDP) due to competitive manufacturing exports.
Worked examples
Example 1: Calculating real GDP growth (4 marks)
In 2022, Country X had a nominal GDP of £500bn. In 2023, nominal GDP rose to £530bn. Inflation during this period was 4%. Calculate the real GDP growth rate.
Answer: Step 1: Calculate the increase in nominal GDP £530bn - £500bn = £30bn increase Percentage increase = (30/500) × 100 = 6% ✓
Step 2: Subtract inflation to find real growth Real GDP growth = 6% - 4% = 2% ✓
Alternatively, deflate 2023 GDP: £530bn / 1.04 = £509.6bn Real growth = (509.6 - 500) / 500 × 100 = 1.92% ≈ 2% ✓✓
Mark scheme notes: 1 mark for correctly calculating nominal growth (6%); 1 mark for subtracting inflation; 2 marks for accurate final answer with working shown.
Example 2: Analysing economic indicators (6 marks)
The table shows data for the UK economy:
| Year | GDP growth | Inflation (CPI) | Unemployment |
|---|---|---|---|
| 2019 | 1.5% | 1.8% | 3.8% |
| 2020 | -9.4% | 0.9% | 4.5% |
Analyse the performance of the UK economy between 2019 and 2020.
Answer: The UK economy experienced severe contraction in 2020, with GDP falling by 9.4% compared to modest growth of 1.5% in 2019 (✓). This represents a recession caused primarily by COVID-19 lockdowns, which forced businesses to close and restricted consumer spending (✓).
Unemployment rose from 3.8% to 4.5%, an increase of 0.7 percentage points (✓). This reflects businesses cutting jobs due to falling demand, though the rise was limited by government support schemes like furlough (✓).
Inflation fell from 1.8% to 0.9%, dropping below the 2% target (✓). Lower consumer spending and falling oil prices during lockdown reduced price pressures, creating deflationary risks (✓).
Mark scheme notes: 2 marks for identifying changes in each indicator with data; 2 marks for explaining causes; 2 marks for linking changes between indicators or providing context.
Example 3: Evaluating the balance of payments (8 marks)
Discuss whether a current account deficit is harmful to an economy.
Answer: A current account deficit can be harmful for several reasons. First, it means a country is spending more on imports than earning from exports, requiring borrowing from overseas to finance the gap (✓). This creates debt that must eventually be repaid with interest, reducing future living standards (✓). Second, persistent deficits may signal lack of international competitiveness, suggesting domestic industries cannot produce goods cheaply or attractively enough for global markets (✓). Third, large deficits can undermine currency values as foreign investors lose confidence, potentially triggering capital flight (✓).
However, deficits are not always problematic. If caused by importing machinery and technology for investment, they can boost future productive capacity and growth (✓). Developing economies often run deficits while building infrastructure. Additionally, if the deficit is small relative to GDP (under 3%), it can be easily financed through foreign investment without creating instability (✓). The UK has maintained deficits for decades whilst continuing to grow, suggesting they can be sustainable in advanced economies with deep capital markets (✓).
Overall, the harm depends on the deficit's size and cause (✓). Small deficits financing investment are acceptable; large deficits funding consumption are concerning.
Mark scheme notes: Level 3 (6-8 marks) requires balanced analysis of arguments on both sides with evaluation. Level 2 (3-5 marks) explains points on one or both sides without evaluation. Level 1 (1-2 marks) makes simple statements without development.
Common mistakes and how to avoid them
Confusing nominal and real GDP — Always check whether GDP figures are adjusted for inflation. Real GDP shows actual growth in output; nominal GDP includes price increases. When calculating growth rates, use real figures unless stated otherwise.
Mixing up unemployment measures — The LFS count is higher than the claimant count because not all unemployed people claim benefits. In exam questions, identify which measure is being used and don't treat them as interchangeable.
Thinking all inflation is bad — Moderate inflation (around 2%) is the government's target. Very low inflation or deflation can harm the economy by encouraging people to delay spending. Distinguish between moderate and high inflation in your answers.
Ignoring trade-offs between objectives — Governments cannot always achieve all four objectives simultaneously. Policies to boost growth might increase inflation; reducing unemployment might worsen the current account deficit. Strong evaluation answers recognise these conflicts.
Assuming GDP equals welfare — GDP measures output, not happiness or quality of life. A country might have high GDP but also high inequality, pollution, or long working hours. Always consider GDP's limitations when discussing living standards.
Forgetting about services in the balance of payments — Students often focus only on trade in goods but the services balance is equally important. The UK typically runs a goods deficit but a services surplus.
Exam technique for "The National Economy: Objectives and Indicators"
Command words matter — "Calculate" requires numerical answers with working shown. "Explain" needs causes/reasons with development. "Analyse" demands links between factors. "Evaluate" requires judgements weighing arguments on both sides. Always match your answer to the command word.
Use data from questions — When extract or data questions are provided, reference specific figures in your answer. "GDP fell from 2.5% to -0.3%" scores higher than "GDP fell." Quote percentages, values, and dates to demonstrate analysis.
Structure extended answers — For 6-8 mark questions, write in paragraphs with clear points. Start with the main argument, explain it with reasoning, provide evidence or examples, then develop with consequences. Finish evaluate questions with "Overall..." judgements weighing the significance of different factors.
Learn benchmark figures — Know that UK inflation targets 2%, unemployment around 4% is considered low, and GDP growth of 2-3% is healthy. This contextualises whether economic data represents good or poor performance.
Quick revision summary
The government pursues four macroeconomic objectives: economic growth (measured by real GDP), low inflation (CPI target of 2%), low unemployment (measured by LFS and claimant count), and balance of payments equilibrium (sustainable current account position). GDP has limitations including exclusion of informal economy and inequality. Inflation is measured through a weighted basket of goods. Unemployment types include structural, cyclical, frictional, and seasonal. The current account records trade in goods and services plus income flows and transfers. These objectives often conflict, creating policy trade-offs.
