Fiscal vs monetary policy and what fiscal policy is for

How does fiscal policy differ from monetary policy?

Fiscal policy is the government’s decisions about spending and taxation. Monetary policy is the central bank’s activity aimed at influencing the quantity of money and credit in the economy. Both are used to smooth the economy over time: to speed up growth when it slows and to cool it when it overheats.

Their shared goal is an economy with positive, stable growth and low, stable inflation. In that environment households can plan saving and spending, and firms can plan investment, without a boom followed by a long slump.

Stabilization policyshared aim: steady growth, low and stable inflation

• Fiscal policy Memorize the government: finance ministry and legislature
  • Government spending goods, services, capital projects
  • Transfer payments pensions, benefits
  • Taxes direct and indirect
• Monetary policy Memorize the central bank
  • Policy rate
  • Open market operations buying or selling government bonds
  • Reserve and liquidity requirements

	Fiscal policy	Monetary policy
Who	government (finance ministry, legislature)	central bank
Levers	spending, transfers, taxes	policy rate, open market operations, reserve requirements
Main channels	aggregate demand directly; incomes after tax	interest rates, credit, asset prices, exchange rate
Extra roles	redistribute income and wealth; allocate resources between sectors	lender of last resort; payments system; price stability
Speed	slow to legislate (indirect taxes are the exception)	fast to decide; effects take time

Government decisions matter because the public sector employs a large share of workers, spends a large share of gross domestic product (GDP) and is the biggest borrower in debt markets. One household or firm cannot move a large economy. A government can.

Exam tip Sort any policy by who acts and on what. Spending and taxes (government) are fiscal. Money, credit and interest rates (central bank) are monetary.

Rules such as a larger deposit required to buy a house are meant to restrain credit and house prices. They are not spending or taxes, so they are not fiscal. The curriculum treats them as monetary-type tools. In practice they are often set by the central bank or a separate financial regulator, never by the finance ministry’s budget.

What is fiscal policy for?

Memorize

Fiscal policy uses government spending and tax revenue to affect three things.

1. The level of aggregate demand , which is the amount households and firms plan to spend, and through it output and employment.
2. The distribution of income and wealth between groups.
3. The allocation of resources between sectors and economic agents.

Roles of fiscal policy

• Influence aggregate demand Memorize and so output and employment
  • Expansionary spend more, tax less: used in a slump
  • Contractionary spend less, tax more: used in a boom
• Redistribute income and wealth Memorize progressive taxes, transfers
• Allocate resources between sectors Memorize subsidies, infrastructure, taxes on harmful goods

In a recession a government can raise spending or cut taxes (expansionary policy) to lift employment and output. In a boom with rising wages and prices it can cut spending and raise taxes (contractionary policy). Typical expansionary moves are cuts in personal income tax, cuts in sales taxes, cuts in company taxes that may lift capital spending, and new public spending on hospitals, schools and infrastructure.

The size and reliability of these effects change over time and across countries. In a deep slump households may save a tax cut as a precaution rather than spend it.

Redistribution works through progressive taxes (rates that rise with income) and transfers to lower-income households. Resource allocation works through subsidies for new or high-risk industries, infrastructure, and taxes on harmful goods such as tobacco.

Two camps disagree on how much fiscal policy can do. Keynesians think it has powerful effects on demand, output and jobs when there is substantial spare capacity. Monetarists think fiscal changes move demand only temporarily and that monetary policy is the better tool for restraining or boosting inflationary pressure.

In rich economies total government spending is often 35 to 50 percent of GDP, and tax and related revenue is similar in scale. That scale is why fiscal changes can matter at the level of a whole economy, and why analysts watch the change in the budget more than its level.

What is the budget balance?

Use it

The budget balance is government revenue minus spending over a fixed period, usually a year. A negative balance is a deficit; a positive one is a surplus. Spending includes interest paid on existing debt. Revenue is tax revenue, and transfer payments are treated as spending.

$$D = G + B - T$$

Here $G$ is spending on goods and services (including debt interest), $B$ is transfer payments and $T$ is tax revenue. A negative $D$ is a surplus. A deficit is financed by borrowing, and the national debt is the pile of past deficits.

Analysts watch the year-to-year change in the balance more than its level. A rising deficit (or falling surplus) signals expansionary policy; the next lesson on stance shows how to read it properly.

Automatic or discretionary?

Memorize

Automatic stabilizers change the budget in the opposite direction to the cycle with no decision. In a slump, incomes and profits fall, so progressive income and profit taxes bring in less, and unemployment benefits and other social payments rise. In a boom the reverse happens. The great advantage is that nobody has to spot a shock and decide how to respond, so the economy reacts less to shocks.

Discretionary fiscal policy is a deliberate change in tax rates or spending programs to steer demand, such as a stimulus package or a freeze on spending.

	Automatic stabilizer	Discretionary policy
Needs a decision?	no	yes
Examples	progressive income tax, unemployment benefit	stimulus bill, new tax rate, spending freeze
Speed	immediate	slow (see the lags lesson)
Effect on the budget in a recession	deficit widens on its own	deficit widens by choice
