4.5.4 - Macroeconomic policies in a global context

Choosing the Policy Mix

Governments usually work with five broad policy levers:

• Fiscal policy: changes in government spending and taxation.
• Monetary policy: changes in interest rates and, indirectly, the supply of money.
• Exchange rate policy: influencing the value of the currency or the exchange rate regime.
• Supply-side policies: measures that raise productivity, efficiency, or flexibility.
• Direct controls: legal or administrative rules such as quotas, minimum wages, or price controls.

The fiscal deficit is the annual gap between government spending and revenue, while the national debt is the accumulated stock of past borrowing. When governments want to reduce a deficit or slow the rise of debt, they usually choose between austerity, growth-led repair, and, in extreme cases, default.

Austerity means lower government spending, higher taxes, or both. In practice this can mean cuts to public services, pay restraint in the public sector, lower welfare spending, and tax rises such as higher VAT. Free-market economists often argue that some spending can be cut by removing waste and improving efficiency.

Austerity can reduce borrowing, but it is controversial because it also withdraws demand from the economy. If spending cuts are large during a weak recovery, growth can slow, living standards can fall, and inequality can widen. Sweden did use a mixture of spending cuts and tax rises to repair its public finances in the 1990s, but that does not prove the same formula will work equally well in every country and every recession.

Keynesian economists emphasise the alternative route: support demand first, then repair the public finances once growth returns. Higher government spending or lower taxes raise aggregate demand, which can lift output, employment, and tax revenue. If unemployment falls, benefit spending also drops. After the 2008-09 financial crisis, the US was generally more willing than the UK to let automatic stabilisers operate and to support demand, and the argument was that a stronger recovery would help the deficit narrow later.

In a recession, automatic stabilisers work mainly because tax receipts fall while transfer payments such as unemployment support rise. That cushions the fall in household income without a new Act of Parliament each time the economy weakens.

Another useful distinction is between a cyclical deficit and a structural deficit. A cyclical deficit appears because the economy is weak: recession lowers tax receipts and raises welfare spending, so borrowing increases even without a major change in policy. A structural deficit remains even when the economy is close to full employment, so it reflects a deeper mismatch between long-run government spending and revenue.

Default is the most extreme route. A government can refuse to repay some or all of its debt, as Russia and Argentina have done in past crises, but the cost is severe. Future borrowing becomes much harder, lenders demand much higher interest rates, and confidence in the economy can collapse. That is why default is usually seen as a last resort rather than a normal policy choice.

Reducing Poverty and Inequality

Most economists agree that free-market outcomes alone will not produce equal incomes and opportunities, although they disagree strongly about how much redistribution is desirable. The main debate is over how far governments should go without weakening incentives, growth, or fiscal sustainability.

Progressive taxes reduce after-tax income inequality because higher earners lose a larger share of their income in tax. Inheritance tax can also reduce wealth inequality by limiting the extent to which large fortunes pass from one generation to the next. The difficulty is that high-income households often have better access to tax planning, so avoidance can weaken the redistributive effect. Critics also argue that if tax rates become too high, revenue may disappoint and incentives to work, invest, or declare income may weaken.

The US has a progressive income tax system, but redistribution is often judged weaker than in Nordic economies because the wider welfare system is less equalising. By contrast, countries such as Finland combine progressive taxation with broader welfare provision and still redistribute heavily.

Transfer payments and public services are another major redistributive tool. Universal benefits go to everyone who meets a broad condition, so they are simple to administer but also give support to richer households. Means-tested benefits are targeted at people with low incomes or low wealth, so they focus help more directly on poverty, but they are more complex and can weaken work incentives if earning extra income causes support to be withdrawn quickly.

Government provision of health, education, and housing can also reduce inequality because access does not depend entirely on private income. That matters especially for children, because it can narrow gaps in opportunity and give people from poorer households a more equal start in life. However, these services are costly, and some of the benefit also goes to higher-income households, so there is still an opportunity cost.

Governments can also try to narrow wage differentials directly. A higher national minimum or living wage raises earnings at the bottom of the labour market, although if set too high it can reduce employment in some sectors. Maximum wages or pay ratios could limit very high incomes, but they may also encourage skilled workers or executives to move elsewhere. Equal pay legislation aims to reduce inequality linked to gender or ethnicity, and more union-friendly laws can strengthen workers' bargaining power, especially in low-paid sectors. Requiring employers to offer benefits such as pensions, sick pay, or medical cover can raise effective remuneration even when the basic wage does not change.

Education matters because inequality is not only about current income. Better schools, extra funding in disadvantaged areas, pupil premium schemes, and wider access to university can improve human capital and social mobility. That is a slower policy than raising benefits, but it can change long-run earning power rather than only short-run disposable income.

Governments sometimes try to help poorer households by capping the prices of essentials such as housing, transport, or energy. The attraction is clear: lower prices raise real spending power. But if a maximum price is set below market equilibrium, shortages can emerge and black markets may develop.

Free-market economists sometimes defend inequality through trickle-down arguments. If richer households, entrepreneurs, and investors keep more of their income, they may invest more, create jobs, and increase demand for others' labour. The counter-argument is the law of diminishing marginal utility: an extra 10 pounds usually adds more welfare to a poor household than to a rich one. That is one reason why high-redistribution countries such as Denmark and Finland are often used to show that equality and economic success are not automatically opposites.

Interest Rates, Money and Competitiveness

Central banks do not just look at domestic inflation. In an open economy they also watch exchange rates, commodity prices, capital flows, and global financial conditions. A cut in interest rates tends to reduce the cost of borrowing, increase demand for loans, and therefore support the supply of money and aggregate demand. A rise in rates does the reverse. In an open economy there is an extra channel: lower interest rates make it less attractive to hold savings in that currency, so short-term "hot money" tends to flow out, the exchange rate tends to fall, and exports become more price competitive.
