What is fiscal policy?

Concept explainer · 2 minFiscal policy: what it changes, and why a government wouldEconplusDalFiscal policy defined as changes to government spending and taxation aimed at aggregate demand, which places it on the demand side before anything else is said about it. Then the reasons to expand: raise growth when the economy is sluggish or in recession, cut cyclical unemployment because labour is a derived demand, and redistribute income through welfare spending and lower rates at the bottom. It also flags the one to handle carefully, raising inflation on purpose, which works in theory and is not the government's job in practice.

Fiscal policy is the use of government spending and taxation to influence the economy.

It is decided by the government, which is the key difference from monetary policy (4.4), decided by the central bank.

The budget position:

PositionMeaning
Budget deficitGovernment spending is greater than revenue
Budget surplusRevenue is greater than spending
Balanced budgetThe two are equal
National debtThe total of all past deficits added up

A deficit is a flow over one year; the national debt is a stock built up over many years. A government can reduce its deficit and still see its debt grow, because any deficit adds to the total.

Government spending and revenue

Main areas of spending: healthcare, education, defence, infrastructure (roads, railways), welfare benefits and pensions, and interest on the national debt.

Main sources of revenue: income tax, corporation tax, VAT or sales tax, excise duties, and national insurance or social contributions.

Direct and indirect taxes

Direct taxIndirect tax
Levied onIncome, profit or wealthSpending on goods and services
Paid to government byThe person who bears itThe seller, who passes it on
ExamplesIncome tax, corporation tax, inheritance taxVAT, excise duty on fuel, alcohol and tobacco

The distinction is who bears the burden: with a direct tax the person taxed pays it; with an indirect tax the shop collects it but the consumer largely bears it.

Progressive, proportional and regressive

This is about the percentage of income paid, not the amount.

TypeAs income rises…Example
ProgressiveThe percentage paid risesIncome tax with higher-rate bands
ProportionalThe percentage stays the sameA flat 20% tax on all income
RegressiveThe percentage paid fallsVAT and excise duties

Why indirect taxes are regressive, the reasoning is worth learning:

Poorer households spend nearly all their income, while richer households save some of theirs → a tax on spending therefore takes a larger share of a poor household's income than of a rich one's → so VAT is regressive even though everyone pays the same rate.

Expansionary and contractionary fiscal policy

StanceActionAimRisk
ExpansionaryRaise spending, cut taxesIncrease demand, reduce unemployment, raise growthInflation if near capacity; larger deficit
ContractionaryCut spending, raise taxesReduce inflation, improve the budgetSlower growth, higher unemployment

How it works, as a chain:

The government cuts income tax → households have more disposable income → they spend more → firms sell more and produce more → they hire more workers → output and employment rise.

Effects on the government's aims

Limitations

Worked example

An economy is in recession, with unemployment at 10%. The government cuts income tax and increases spending on building schools.

Lower income tax → higher disposable income → more consumer spending. Higher government spending → construction firms hire workers → those workers spend their wages too → demand rises further → output and employment increase.

Drawbacks to weigh:

A judgement: in a deep recession with idle resources, expansionary fiscal policy is likely to raise output rather than prices, so the inflation risk is small, the stronger objections are the time lag and the debt.

Common exam mistakes

Exam technique

Always state whether a policy is expansionary or contractionary, then trace the chain to output, employment and prices.

For tax questions, use the phrase percentage of income; that is what distinguishes progressive from regressive.

For evaluation, three reliable angles: time lags, the deficit and debt, and the effect on other aims, especially the balance of payments.

Building an answer

4 marks, "Explain how expansionary fiscal policy could reduce unemployment."

The government raises its own spending or cuts taxation, which increases total demand in the economy.
Firms facing higher demand need more workers to produce the extra output, so they hire, and unemployment falls. Cutting income tax works through the same channel by raising households' disposable income and therefore their spending.

6 marks, "Analyse the effects of a rise in income tax."

Disposable income falls, so consumption falls and total demand in the economy weakens. Output and employment may fall with it.
Government revenue rises, allowing more spending on healthcare and education, or a smaller budget deficit.
The distributional effect depends on the design: a rise in the higher rate is progressive and narrows income inequality, while a rise in the basic rate affects lower earners proportionally more.
Incentives may weaken, very high marginal rates can discourage extra work, though evidence for this at ordinary tax levels is weak, so the effect should be stated as possible rather than certain.

Direct against indirect taxes

UsuallyProgressiveRegressive
Effect on incentivesMay discourage workDiscourages consumption of the taxed good

Progressive means the rate rises with income; regressive means it takes a larger share of a low income; proportional means the same share regardless. Indirect taxes are regressive because a poorer household spends a larger share of income.

A real case to quote

The UK's 2021 corporation tax announcement. The main rate was set to rise from 19% to 25% in 2023, with a lower rate retained for small companies. It illustrates both sides of the argument in one policy: revenue for deficit reduction, weighed against the fear that higher business taxes deter investment, and the compromise of protecting small firms shows how design matters as much as the rate.

Check you have it

A government wants to reduce both its budget deficit and the amount of poverty in its country. Which fiscal policy measure is most likely to achieve both of these aims?
