Cutting the budget deficit is a key government objective, but at the moment it seems to be in conflict with another objective, namely economic growth and thereby avoiding a double-dip recession. In order to raise tax revenue and meet the cries for more equity, the 50% tax rate above £150,000 was imposed, affecting some 310,000 people. However, in a recent letter from some top economists to the Financial Times, they called for the scrapping of the top rate of tax. They argue that it is hindering entrepreneurship and encouraging potential top rate tax payers to leave the UK, thereby hindering the economic situation. George Osborne has asked HMRC to evaluate just how effective the top rate of tax has been at generating government revenue.

In contrast to these calls for scrapping this top rate of tax, some of the richest people in the world have said that they would be happy to pay this rate of tax. In the words of Sir Stuart Rose, the ex-boss of Marks and Spencer:

“How would I explain to my secretary that I would pay less tax on my income, which is palpably bigger than hers, when her tax is not going down.”

Those against scrapping the tax argue that it will be ‘monstrously unfair’ and ‘phenomenally immoral’. This, combined with official figure that suggest by 2015/16 the top rate tax will bring in an extra £3.2bn more revenue than had the tax remained at 40%, certainly adds weight to their argument. In total, over the five year period, it is predicted to bring in an extra £12.6bn.

The policy to increase the tax threshold to £10,000 will meet with the critics’ approval, but less so, if it is accompanied by a scrapping of this top rate tax. Furthermore, the government’s coffers will take a significant beating if both of the above occur!

Another option to replace the 50% tax rate is a higher tax on high value homes – the so-called ‘mansion tax’. Whatever happens with taxation, one thing is clear: the government needs to find a way to generate tax revenue, without putting the economy back into recession. If the 50% tax rate encourages people to leave the UK to avoid the tax or to forego entrepreneurship, it will directly be acting as a disincentive. Fewer jobs will be created due to a lack of entrepreneurship, output may be lower and hence growth will not reach its potential. Crucially, the international competitiveness of the UK economy is being badly affected, as it becomes a less attractive place for investment and talented workers. The following articles consider the 50% tax rate and the controversy surrounding it, despite it only being a temporary policy.

Approximately 1.6 million past and present female employees of Walmart have had their sex discrimination case dismissed by the US Supreme Court. This case began almost 10 years ago with claims by 5 female workers that they were paid less than their male counterparts and had been passed over for promotion. Despite statistical evidence suggesting a case of sexual discrimination, it was ruled that Walmart was not discriminating against women, as promotion decisions were made by individual managers, hence there was no common element between the plaintiffs. Justice Antonin Scalia said that a common element was ‘entirely absent here’.

Discrimination of any kind will have an impact on the demand curve for labour (or the marginal revenue product curve). As such, the equilibrium wage rate will also be affected: if a firm believes that women are less productive than their male counterparts, the MRP curve will shift inwards, pushing down their wage. The key to this case was that there were so many plaintiffs and so it was practically impossible to determine whether or not pay differentials and promotions were based on legitimate grounds. The following articles consider the case against Walmart.

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.

The snow the UK has seen over the past two winters created massive disruption, but that is only one reason for hoping for a milder winter to come. With the cold weather, the UK economy faced threats of gas shortages, as households turned on their heating. However, despite the freezing temperatures, many households were forced to turn off their heating regularly, due to the excessive bills they would face. This trend is expected to be even more prevalent if the 2011/12 winter is as cold, as fuel tariffs are predicted to rise. The Bank of England has said that gas and electricity prices could rise this year by 15% and 10% respectively. British Gas’s Parent company, Centrica said:

“In the UK the forward wholesale prices of gas and power for delivery in winter 2011/12 are currently around 25% higher than prices last winter, with end-user prices yet to reflect this higher wholesale market price environment.”

These predictions might see the average UK household paying an extra £148 over the next year. Although these are only estimates, we are still very likely to see many households being forced to turn off their heating. One thing which therefore is certain: a warmer winter would be much appreciated!
