Macroeconomic policies in a global context

The toolkit and its uses

• Fiscal policy (spending and taxes), monetary policy (interest rates, money supply, QE), exchange rate policy (intervention, pegs), supply-side policies (education, deregulation, infrastructure, incentives) and direct controls (price and wage controls, capital controls, import quotas).

Uses:

• Reduce deficits and debt: fiscal consolidation (spending cuts, tax rises), supported by low interest rates and growth-friendly supply-side reform.
• Control inflation: higher interest rates, fiscal tightening, a stronger currency, price controls in some countries.
• Respond to external shocks: for example a fall in export demand or an oil price rise; floating exchange rates and automatic stabilisers cushion them.
• Reduce poverty and inequality: progressive taxes, benefits, minimum wages, spending on education and health.

Demand-side policies after the 2008 global financial crisis

When the 2008 crisis caused a collapse in credit, confidence and AD, many governments and central banks used:

• Monetary policy: interest rates cut to historically low levels; quantitative easing, with central banks creating money to buy bonds, lowering long-term interest rates; rescues of banks.
• Fiscal policy: fiscal stimulus (spending increases, tax cuts) and automatic stabilisers allowed deficits to rise sharply; later, many countries switched to austerity to reduce deficits and debt.

Evaluation: these policies helped prevent a deeper depression, but recovery was slow, QE is widely thought to have raised asset prices (benefiting wealth holders), and higher debt limited later policy options.

Controlling TNCs

• Reducing tax avoidance: international agreements on minimum corporate tax rates and sharing information between tax authorities.
• Regulating transfer pricing: the 'arm's length' principle, requiring internal prices to match what independent firms would pay; country-by-country reporting of profits and taxes.
• Limits: TNCs can move activity and profits between countries; governments compete for investment; enforcement needs international cooperation; TNCs have strong lobbying power and some have annual revenues larger than the GDP of small economies.

Impact of policy and problems for policymakers

Policy changes in large economies spill over: a US interest rate rise can cause capital outflows from emerging economies and weaken their currencies; tariffs affect partners' exports.

Problems:

• Inaccurate information: data are late and revised; the output gap cannot be observed.
• Risks and uncertainties: time lags, unknown size of multipliers, how people will react.
• Inability to control external shocks: commodity prices, global recessions, pandemics, conflicts.

Policies also conflict: reducing a deficit may raise unemployment; cutting inflation with higher interest rates may hurt growth.

Worked example

Explain why cutting interest rates had a limited effect on AD after the 2008 financial crisis, and what central banks did as well.

1. Rates were cut close to zero but could not go much lower.
2. Banks were reluctant to lend and households and firms wanted to reduce debt, so lower rates did not boost borrowing much.
3. Central banks added quantitative easing to lower long-term rates and increase the money supply.

Answer: Low confidence and damaged banks weakened the effect; central banks used QE too.

Check yourself

1. Quantitative easing involves
   • the government cutting income tax
   • the central bank raising interest rates
   • the central bank creating money to buy financial assets such as government bonds
   • a fixed exchange rate
   Show answer

   the central bank creating money to buy financial assets such as government bonds. QE increases the money supply and lowers long-term rates.

2. Which policy combination is most likely to reduce inflation caused by excess demand?
   • Higher interest rates and a cut in government spending
   • Lower interest rates and higher spending
   • QE and tax cuts
   • Devaluation and lower interest rates
   Show answer

   Higher interest rates and a cut in government spending. Both reduce AD.

3. Explain one way governments can reduce tax avoidance by TNCs, and one limit to this.
   Show answer

   Requiring transfer prices to follow the arm's length principle (or agreeing a global minimum corporate tax rate) reduces profit shifting, but TNCs can still move real activity to low-tax countries, and enforcement needs international cooperation.. Name a measure and a limit.

4. Why can time lags make fiscal and monetary policy destabilising?
   • Policies work instantly
   • By the time the policy takes effect, the economy may already be recovering
   • Lags only affect exchange rates
   • Lags make data more accurate
   Show answer

   By the time the policy takes effect, the economy may already be recovering. A stimulus that arrives late can overheat the economy.

5. Explain one reason why governments allowed budget deficits to rise after the 2008 financial crisis.
   Show answer

   Automatic stabilisers and fiscal stimulus supported aggregate demand when private spending collapsed, preventing a deeper recession and higher unemployment.. Deficits supported AD.

6. A large rise in US interest rates is most likely to cause, in an emerging economy,
   • capital inflows and an appreciation
   • capital outflows and a depreciation of its currency
   • an automatic fall in its inflation
   • an improvement in its terms of trade
   Show answer

   capital outflows and a depreciation of its currency. Investors move funds to the US for higher returns.

7. Explain one conflict between macroeconomic objectives a government may face when reducing a budget deficit.
   Show answer

   Cutting spending or raising taxes reduces AD, which lowers growth and raises unemployment, so deficit reduction conflicts with growth and employment objectives.. Contractionary fiscal policy has costs.
