Macroeconomic objectives
Economic growth, low and stable inflation, low unemployment, current account equilibrium, balanced government budget, greater income equality
Balanced government budget
Government spending = tax revenue (no deficit)
Budget deficit vs national debt
Deficit = annual shortfall (flow). Debt = accumulated total owed (stock)
Current account equilibrium
Sustainable balance: no large persistent deficit or surplus
Conflict: inflation vs unemployment
Higher AD cuts unemployment but raises inflation
Short-run Phillips curve
Inverse relationship between unemployment and inflation in the short run
Conflict: growth vs environment
More output means more pollution, emissions and resource depletion
Conflict: inflation vs current account
Higher inflation makes exports less competitive, worsening the current account. Raising interest rates to cut inflation can strengthen the currency, also hurting exports
Conflict: growth vs equality
Growth may favour the skilled and capital owners. Redistribution may weaken incentives and growth
Evaluating conflicts
Depends on the cause of the change: supply-side growth (higher LRAS) can achieve several objectives at once
Supply-side policies
Policies to raise LRAS by increasing productivity, competition and incentives
Free-market supply-side policies
Deregulation, privatisation, tax cuts, lower welfare payments, cutting bureaucracy for firms
Deregulation
Removing rules in product and labour markets to increase competition and flexibility
Privatisation
Transferring state-owned firms to the private sector to raise efficiency through the profit motive
Tax cuts as a supply-side policy
Lower income tax raises the incentive to work. Lower corporation tax raises the incentive to invest
Lower welfare payments
Increases the incentive to find work, but may raise poverty and inequality
Interventionist supply-side policies
Education and training, investment incentives (tax relief or subsidies), infrastructure, start-up finance, regional policy
Infrastructure investment
Transport, energy and digital networks cut firms' costs and raise productivity
Regional policy
Incentives that bring jobs and investment to deprived regions
Strengths of supply-side policies
Raise LRAS, so growth without inflation. Can cut structural unemployment. Improve competitiveness
Weaknesses of supply-side policies
Long time lags, expensive (opportunity cost), uncertain effects, free-market versions may raise inequality
Demand-side policies
Policies that change AD: fiscal policy and monetary policy
Fiscal policy
Using government spending and taxation to influence AD
Monetary policy
Using interest rates, money supply and credit conditions to influence AD (usually by the central bank)
Reflationary (expansionary) policy
Raises AD: higher spending, lower taxes, lower interest rates, QE
Deflationary (contractionary) policy
Reduces AD: lower spending, higher taxes, higher interest rates
Monetary policy instruments
Interest rates, quantitative easing, lending criteria, reserve (liquidity) requirements
Quantitative easing (QE)
Central bank creates money to buy assets (mainly government bonds), raising the money supply and lowering long-term interest rates
Lending criteria
Rules on who banks may lend to and how much. Looser criteria raise credit and AD
Reserve (liquidity) requirements
Share of deposits banks must hold as reserves. A higher ratio means less lending
Role of central banks
Implement monetary policy, hit the inflation target, act as banker to the government, act as banker to the banks (lender of last resort)
Lender of last resort
The central bank lends to banks in a crisis to prevent the financial system collapsing
Strengths of fiscal policy
Can target specific sectors or regions. Strong in a deep recession (multiplier)
Weaknesses of fiscal policy
Time lags, budget deficits and debt, crowding out, political influence
Strengths of monetary policy
Quick to change, independent of politics, effective against inflation
Weaknesses of monetary policy
Time lags of 18–24 months, weak when rates are near zero, blunt (affects all regions), may hurt exporters via the exchange rate
