Fiscal Policy
Government budgets move bond yields, corporate earnings and growth forecasts, and fiscal shocks can unsettle whole markets, as the UK learned in 2022. This module explains what fiscal policy tries to achieve, which spending and tax tools it uses, how far a change in spending or taxes moves output, when government debt becomes a concern, and how to judge whether policy is really expansionary once the effect of the business cycle is stripped out.
What you will learn
1. Compare the roles and objectives of fiscal policy and monetary policy, and distinguish discretionary fiscal policy from automatic stabilizers.
- Fiscal policy = government spending and taxation; monetary policy = central bank control of interest rates, money and credit.
- Fiscal roles: stabilize aggregate demand, redistribute income and wealth, allocate resources.
- Automatic stabilizers (progressive taxes, unemployment benefits) act without new decisions.
- Discretionary policy consists of deliberate changes to spending or tax rules.
- Primary balance = budget balance excluding interest payments.
2. Describe the main fiscal policy tools on the spending and revenue sides, the desirable attributes of a tax system, and the advantages and disadvantages of different tools.
- Spending tools: transfer payments, current spending and capital spending.
- Direct taxes fall on income, wealth and profits; indirect taxes fall on spending.
- Good tax attributes: simplicity, efficiency, fairness (horizontal and vertical equity), revenue sufficiency.
- Indirect taxes can be changed quickly and target behaviour but tend to be regressive.
- Capital spending raises productive capacity but is slow to implement.
3. Calculate and interpret the fiscal multiplier and the balanced budget multiplier, and explain how crowding out and Ricardian equivalence can weaken the effect of fiscal policy.
- Spending multiplier = 1 / [1 - c(1 - t)], with c = MPC and t = tax rate.
- A tax cut raises first-round spending by only c x the cut, so its effect is smaller than an equal spending rise.
- Balanced budget multiplier is positive: 1 with no income tax, below 1 with a proportional tax.
- Crowding out: higher interest rates from government borrowing reduce private investment.
- Ricardian equivalence: anticipated future taxes lead households to save tax cuts.
4. Evaluate the arguments for and against being concerned about the size of a government's deficit and debt, and explain how interest rates, growth and the primary balance drive the debt-to-GDP ratio.
- Concerns: higher future taxes, loss of market confidence, monetization and inflation, crowding out.
- Counterarguments: domestically held debt, productive investment, Ricardian equivalence, support for output in slumps.
- Debt in a foreign currency or without a national central bank is riskier.
- Sustainability is judged by the debt-to-GDP ratio.
- If interest rates exceed growth, a primary surplus is needed to stabilize the debt ratio.
5. Explain the difficulties of implementing fiscal policy, including recognition, action and impact lags, and determine whether fiscal policy is expansionary or contractionary using the structural budget balance.
- Recognition lag (seeing the problem), action lag (deciding and legislating), impact lag (taking effect).
- Mistimed stimulus can amplify the cycle; expansion at full employment mainly raises inflation.
- The actual deficit widens automatically in recessions, so it is a poor measure of policy stance.
- Structural balance = actual balance minus the cyclical component.
- Rising structural deficit = expansionary policy; falling structural deficit = contractionary policy.
Module at a glance
- Fiscal policy stabilizes demand, redistributes income and allocates resources; monetary policy works through rates and credit.
- Automatic stabilizers act without new decisions; discretionary measures require legislation.
- Good taxes are simple, efficient, fair (horizontal and vertical equity) and raise sufficient revenue.
- Spending multiplier = 1 / [1 - c(1 - t)]; tax cuts have smaller effects; the balanced budget multiplier is positive.
- Crowding out and Ricardian equivalence weaken fiscal policy.
- Debt sustainability depends on the debt ratio, interest versus growth, the primary balance, the currency and who holds the debt.
- Recognition, action and impact lags make fiscal timing difficult.
- Judge the stance by the structural balance, not the actual deficit.
