Taxes are a key element in redistributive policies: taxes on the rich can be spent on benefits to the poor. The more progressive the taxes (i.e. the more steeply they rise with rising incomes), the bigger will be the redistributive effect and hence the more equal will post-tax incomes be.
But high and steeply progressive taxes can act as a disincentive to work longer, or to go for promotion or to move to a better paid job. High corporate taxes and income taxes can act as disincentive to inward investment and may encourage a ‘brain drain’ and capital flight with people and capital leaving the country for lower tax regimes abroad.
Raising taxes has two effects. First there is the substitution effect: people may work less and substitute it with leisure – after all, work is now less rewarding. People may also substitute working abroad for working at home. But the second effect works in the opposite direction. This is the income effect. As taxes are raised and people’s take-home pay is thereby reduced, they may feel the need to work longer hours or try harder for promotion in order to make up the lost income and maintain their living standards. Thus the effect of higher taxes is not clear-cut. It is an empirical question of which of the two effects is the stronger.
One important determinant of the effects of different tax rates is their relative position compared with other countries. Another is the international mobility of labour and capital. The greater the mobility, the greater the elasticity of supply with respect to changes in tax rates.

Inequality is growing in most countries. This can be illustrated by examining what has been happening to countries’ Gini coefficient. The Gini coefficient measures income inequality, where 0.00 represents perfect equality, with everyone in the country earning the same, and 1.00 represent perfect inequality, with one person earning all the country’s income. (Note that sometimes it is expressed as the ‘Gini index’, with 100 representing perfect inequality). In virtually all countries, the Gini coefficient has been rising. In the OECD countries it has risen by an average of 0.3% per annum over the past 25 years. The OECD average is now 0.31.
But despite the fact that the Gini coefficient has been rising, its value differs markedly from one country to another, as does its rate of change. For example, Finland’s Gini coefficient, at 0.26, is below the average, but it has been rising by 1.2% per annum. By contrast, Turkey’s Gini coefficient, at 0.41, is above the average and yet has been falling by 0.3% per annum.
The most unequal of the developed countries is the USA. According to OECD data, its Gini coefficient is 0.38, well above the values in the UK (0.34), Japan (0.33), Germany (0.30) France (0.29) and Denmark (0.26). What is more, inequality in the USA has been increasing by an average of 0.5% per annum since the mid 1980s.
According to the United Nations’ Human Development Report 2010, the USA’s Gini coefficient is even higher, at 0.41 (see Table 3 of the report). But this is still below that of Russia, with a figure of 0.44, a figure that has markedly worsened over time, along with those of other former Soviet countries. According to the report (page 72):
The worsening is especially marked in countries that were part of the former Soviet Union – which still have relatively low Gini coefficients because they started with low inequality. Transition has eroded employment guarantees and ended extensive state employment. Before the fall of the Berlin Wall, 9 of 10 people in socialist countries were employed by the state, compared with 2 of 10 in Organisation for Economic Co-operation and Development economies. While the privileged elite (the nomenklatura) often attained higher material well-being, the measured differences in income were narrow.
The Gini coefficient for Russia is the same as the average of the 39 developing countries with the lowest level of human development &nbash; and developing countries are generally much less equal than developed ones. Of course, some developing countries have an even higher Gini coefficient: for Angola the figure is 0.59; for Haiti it is 0.60.

There’s been a lot of bad news about the economy, but perhaps things are looking up. Inflation is now at 4% and the latest data suggests that unemployment has fallen, with more jobs being created in the private sector. An estimated 143,000 jobs were created, many of which were full-time and the ILO measure if unemployment is down by some 17,000. There is still some doom and gloom, as growth in annual average earnings has fallen slightly and this will undoubtedly affect retail sales. Numbers claiming JSA have also increased marginally to 1.5 million and youth unemployment has seen a small increase to 20.4%. A big area of concern is that unemployment might rise in the coming months due to the time lag. Growth in the last quarter of 2010 was negative and this could increase unemployment when the full effects are felt in the labour market later in the year. Howard Archer, the Chief Economist at HIS Global Insight had this to say about the latest data.
‘Despite the overall firmer tone of the latest labour market data, we retain the view that unemployment is headed up over the coming months. We suspect that likely below-trend growth will mean that the private sector will be unable to fully compensate for the increasing job losses in the public sector that will result from the fiscal squeeze that is now really kicking in. Indeed, we believe that private sector companies will become increasingly careful in their employment plans in the face of a struggling economy and elevated input costs.’
The wage price spiral hasn’t begun as many though, and this may encourage the Bank of England to keep interest rates down, especially as inflation has come down to 4% and concerns about growth still remain. So despite good news about unemployment overall falling, young workers, women and public sector workers have not benefited. Youth unemployment is up, more women are claiming JSA and more jobs in the public sector are expected to be cut this year. The following articles consider the implications.

As the new tax year begins, many changes are taking place. In order to cut the large budget deficit, sacrifices have to be made by all. The tax and benefit changes could make households worse off by some £2bn this year – definitely not good news for those households already feeling the squeeze. However, the Coalition say that the poorest households will be made better off relative to the rich.
Personal allowance is increasing by £1,000, which is expected to benefit £800,000 people who will no longer pay any tax. At the same time, the 40% tax bracket is being reduced from £43,875 to £42,475, which will bring another 750,000 people into this higher tax bracket, bringing in much needed revenue for the government. Employee’s national insurance contributions will rise by 1% and according to Credit Action, this will leave households £200 worse off per year. Benefits do rise with inflation, but they are to be indexed against the CPI rather than the RPI. The RPI is usually higher and hence benefits will not increase by as much, again leaving some people worse off. Child benefit will be frozen for all and will then be removed for higher rate tax payers from 2013. According to the Treasury, it is the top 10% of households who will lose the most from these needed changes. However, as Justine Greening, the Economic Secretary to the Treasury said:
‘Labour left behind a complete mess with no plan to deal with it, apart from to run up more debts for the next generation to pay off.’
In order to cut the deficit, which stands at an estimated £146bn, spending must fall and tax revenue for the government must rise. The government argues that if cuts are not made today, even higher cuts will be necessary in the future and this will harm the poorest even more. Whilst the Treasury have accepted that there was a ‘marginal loss’ across the population, it is the highest earning households that will suffer the most.

- What is the likely impact of the 1% rise in NICs? Think about the income and substitution effects. Can you illustrate the effect using indifference analysis?
- Why are Labour arguing that women and children will be hit the hardest and the coalition arguing that it is the highest income households who will lose the most? Can both parties be right?
- What are the arguments (a) for and (b) against bringing in tax and benefit changes today rather than in a few years?
- How might these changes affect the economic recovery?
- Is it equitable that child benefit should eventually be removed from those paying the higher rates of income tax?
- Why has the government indexed benefit payments to rise in line with the CPI rather than the RPI?
An interesting article by Stephanie Flanders, the BBC’s Economics editor. She asks just how much (or how little) the pound in our pocket is now worth. With inflation above target, growth very slow and tax and benefit changes to cut the government deficit, everyone is feeling the squeeze. A key fact that Flanders identifies is that only those in the highest income quintile have actually lost from changes in the tax and benefits system: everyone else has (or will) gain. A very interesting read!
