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.

In January 2011, Chinese growth accelerated to 9.8% as industrial production and retails sales picked up. As the second largest economy, this very high growth is hardly surprising, but it has caused concern for another key macroeconomic variable: inflation. Figures show that inflation climbed to 5.2% in March from a year before and the billionaire investor George Soros has said it is ‘somewhat out of control’. High property and food prices have contributed to high and rising inflation and this has led to the government implementing tightening measures within the economy.
In March, growth in property prices did finally begin to slow, according to the survey by the National Bureau of Statistics. Prices of new built homes had risen in 49 out of 70 Chinese cities in March from the previous months, but this was down from 56 cities in February. A property tax has also been implemented in cities like Shanghai and the minimum down payment required for second-home buyers has risen in a bid to prevent speculative buying. Bank reserve requirements have also been increased for the fourth time, after an increase in the interest rate at the beginning of April. The required reserve ratio for China’s biggest banks has now risen to 20.5%.
The situation in China is not the only country causing concern. Inflation in emerging markets is a growing concern, especially for the richer nations. The Singaporean finance minister, Tharman Shanmugaratnam, said:
“When inflation goes up in emerging markets, it’s not just an emerging market problem, it’s a global inflation and possibly interest rate problem … We have learned from painful experience in the past few years that nothing is isolated and that risk in one region rapidly gets transmitted to the rest of the world.”
He has said that inflation in emerging markets needs addressing to ensure that it does not begin to threaten the economic recovery of other leading economies. The following articles consider the latest Chinese developments.

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.
