2.6.1 Possible macroeconomic objectives

Governments judge the performance of the economy against a set of macroeconomic objectives. Some have explicit numerical targets, such as the 2% inflation target set for the Bank of England. Others are broader aims that governments describe in their budgets and manifestos. This topic covers the seven objectives in the specification, why each matters, and how each is measured.

Why governments have objectives

Macroeconomic objectives give policy a direction. They let the public, businesses and financial markets judge whether policy is working, and they shape decisions about interest rates, taxation and government spending.

The objectives are related. Progress on one can help another, as when faster growth reduces unemployment. But objectives can also conflict, as when faster growth pushes up inflation. Those conflicts are covered in 2.6.4 Conflicts and trade-offs between objectives and policies.

Economic growth

What it means. Economic growth is an increase in real GDP. A common aim is sustained and sustainable growth: steady growth over time, rather than a boom followed by a bust, that does not damage the environment or the prospects of future generations.

Why it matters

• Higher real incomes and, usually, higher living standards.
• More jobs, as firms need more workers to produce more output.
• Higher tax revenue without raising tax rates, which can pay for public services.

How it is judged. Growth is measured by the percentage change in real GDP. The UK's long-run trend rate of growth has been estimated at around 2% a year, but it has been lower since the financial crisis of 2008. Real GDP per head is a better guide to living standards, because it allows for population growth. The measurement of growth is covered in 2.1.1 Economic growth.

Low unemployment

What it means. The aim is to keep the number of people who are willing and able to work, but cannot find a job, as low as possible. Some unemployment is unavoidable, as people move between jobs, so the aim is low unemployment rather than zero.

Why it matters

• Unemployed workers are wasted resources, so output is below what the economy could produce.
• Unemployment means lost income, which causes hardship and can widen inequality.
• It costs the government money through benefits paid and taxes not received.
• Long periods out of work reduce skills and can damage health and confidence.

How it is judged. The unemployment rate is measured using the Labour Force Survey, which follows the International Labour Organization definition. The claimant count is an alternative measure. Both are covered in 2.1.3 Employment and unemployment.

Low and stable rate of inflation

What it means. In the UK, the government sets the Bank of England a target of 2% a year for inflation, measured by the Consumer Prices Index. The aim is a rate that is both low and stable, so that households and firms can plan with confidence.

Why it matters

• High inflation reduces the real value of incomes and savings, particularly for people on fixed incomes.
• Unpredictable inflation makes firms less willing to invest, because they cannot be sure of future costs and prices.
• If UK inflation is higher than in other countries, UK goods become less price competitive.

Why the target is not zero. A small positive rate gives a margin of safety against deflation, which can lead consumers to delay spending and raises the real burden of debt. How inflation is measured is covered in 2.1.2 Inflation.

Balance of payments equilibrium on current account

What it means. The current account records trade in goods and services, primary income and secondary income with the rest of the world. Equilibrium means the current account is roughly balanced over time, with no large or persistent deficit or surplus.

Why it matters

• A large and persistent current account deficit must be financed by borrowing from abroad or by selling assets to foreign investors. This may not be sustainable.
• A deficit may signal that domestic firms are not internationally competitive.
• A large surplus is not ideal either, because it means the economy is consuming less than it produces.

How it is judged. The current account balance is usually expressed as a percentage of GDP, which allows comparison over time and between countries. The UK has run a current account deficit in almost every year since the mid-1980s. The structure of the balance of payments is covered in 2.1.4 Balance of payments.

Balanced government budget

What it means. A balanced budget means government revenue, mainly from taxation, equals government spending over a year. If spending is greater than revenue, there is a budget deficit and the government must borrow. If revenue is greater than spending, there is a budget surplus.

Why it matters

• Deficits add to the national debt, and interest must be paid on that debt. Money spent on debt interest has an opportunity cost.
• High debt may make lenders less willing to lend, raising the cost of borrowing.
• Persistent deficits may reduce the government's room to respond to a future recession.

In practice, governments rarely aim for an exact balance every year. UK governments set fiscal rules, such as balancing day-to-day spending against revenue while borrowing to invest, and getting debt falling as a percentage of GDP. The Office for Budget Responsibility (OBR) produces independent forecasts of the public finances and judges whether the government is on track to meet its rules.

Protection of the environment

What it means. Governments increasingly aim to make sure that economic activity does not cause lasting damage to the environment. This includes cutting greenhouse gas emissions, reducing pollution and waste, and protecting natural resources.

Why it matters

• Growth that depletes resources or damages the climate may not be sustainable, so it reduces the living standards of future generations.
• Pollution harms health and imposes external costs on third parties.

In practice, the UK has a legally binding target to reach net zero greenhouse gas emissions by 2050. This objective is linked to the microeconomic tools covered in 1.4.1 Government intervention in markets, such as environmental taxes, regulation and tradable pollution permits.

Greater income equality

What it means. The aim is to narrow the gap between the incomes of high-income and low-income households. It does not mean that everyone should earn the same, but that the distribution of income should be judged fair.

Why it matters

• Wide inequality can mean that some households cannot afford essentials, even in a rich economy.
• It may reduce social mobility, if children from low-income families have fewer opportunities.
• It can weaken social cohesion and trust.

How it is pursued. Governments redistribute income through progressive taxes, such as income tax, and through benefits and the provision of public services such as education and health care. Whether greater equality is desirable, and how far it should go, involves value judgements. Some argue that some inequality is needed to provide incentives to work and take risks.

Summary of the objectives

Key terms

Common mistakes

• Aiming for zero inflation or zero unemployment. The UK inflation target is 2%, not zero, and some frictional unemployment is always present.
• Confusing the budget balance with the current account. The budget balance is about government revenue and spending. The current account is about the UK's transactions with the rest of the world.
• Treating a current account deficit as automatically bad. A small deficit financed by long-term investment from abroad may be sustainable. What matters is its size and persistence.
• Describing growth without saying real. An increase in nominal GDP may only reflect higher prices.
• Listing objectives without explaining why they matter. Each objective should be linked to its effect on living standards, firms or the public finances.
• Assuming objectives always move together. Some support each other, but others conflict, especially in the short run.

Where this goes next

The measures behind these objectives are covered in 2.1.1 Economic growth, 2.1.2 Inflation, 2.1.3 Employment and unemployment and 2.1.4 Balance of payments. The policies used to pursue them are covered in 2.6.2 Demand-side policies and 2.6.3 Supply-side policies, and the conflicts between them in 2.6.4 Conflicts and trade-offs between objectives and policies. Inequality is examined in more depth in 4.2.2 Inequality, and the public finances in 4.5.3 Public sector finances.
