Divided we stand is the title of a new report by the Organisation for Economic Co-operation and Development (OECD). Its sub-title is “Why inequality keeps rising”. The report shows how the gulf between rich and poor has widened in most countries, both developed and developing. As the introduction states:

In the three decades prior to the recent economic downturn, wage gaps widened and household income inequality increased in a large majority of OECD countries. This occurred even when countries were going through a period of sustained economic and employment growth.

The report analyses the major underlying forces behind these developments. Its conclusion is that inequality looks set to continue widening, especially with the worldwide economic slowdown and rise in unemployment. However, the report says that “there is nothing inevitable about growing inequalities. Globalisation and technological changes offer opportunities but also raise challenges that can be tackled with effective and well-targeted policies.”

So just what is the extent of inequality? How has it changed over time? And what can be done to reduce inequality? The webcast produced by the OECD to accompany the report looks at the problem, and the report and articles look at what can be done about it.

Questions

  1. Why may inequality be seen as a ‘bad thing’ for society as a whole and not just the poor?
  2. Does it matter for the poor if rich people’s incomes grow at a greater rate than those of the poor so long as the incomes of the poor do indeed grow?
  3. Explain what is meant by the Gini coefficient. What has happened to the Gini coefficient over the past few years across the world?
  4. Are there any common explanatory features in the economies of those countries where income inequality is growing rapidly? Similarly, are there any common explanatory features in the economies of those countries where income inequality is not growing, or growing only very slowly?
  5. What are the causes of rising inequality?
  6. Identify policies that can be adopted to tackle growing inequality.
  7. What problems arise from policies to reduce inequality by (a) reducing inequalities in disposable income; (b) providing more free services to all, such as healthcare and education? How might these problems be mitigated?

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.

Questions

  1. Why may relative income tax rates between countries give only a partial picture of the international competitiveness of these countries? What else would need to be taken into account?
  2. Does making taxes more steeply progressive necessarily act as a disincentive to output? Explain.
  3. What factors are likely to determine the relative size of the income and substitution effects of tax changes?
  4. How progressive are income taxes in the UK compared with other countries? Give examples.
  5. What externalities (positive and negative) might result from steeply progressive income tax rates?
  6. What determines the international elasticity of supply of labour?
  7. What is the Laffer curve? How will the shape of the Laffer curve be affected by the international mobility of labour and international tax rates?

The recession caused a large rise in unemployment in many countries. In the USA the rise has been particularly steep, where unemployment now stands at 14.5 million, or 9.8% of the labour force. Unemployment has continued to rise despite renewed growth in the US economy, where the latest annual real GDP growth is 2.6% (measured in Q3 2010). The rise in unemployment has been blamed on ‘sticky wages’ – i.e. the reluctance of wage rates to fall.

But are wages genuinely sticky as far as the average worker is concerned? They may be in many specific jobs with specific employers, but many workers made redundant then find work in different jobs at lower rates of pay. For them, their wage has fallen, even if particular jobs are paying the same as before.

So what are the consequences of this? Does the willingness of workers to accept lower paid jobs mean that the labour market is flexible and that people will thus price themselves into work? If so, why is employment still rising? Or does a reduction in real wages for many people dampen spending and hence aggregate demand, thereby reducing the demand for labour? If so, why is GDP rising?

The following articles look at the apparent stickiness of wages and the implications for the labour market and the macroeconomy.

Questions

  1. Why might nominal wages be sticky downwards in specific jobs in specific companies?
  2. Why might nominal average wages in the economy not be sticky downwards?
  3. Why is unemployment rising in the USA?
  4. Why might there be a problem of hysteresis in the USA that provides an explanation of the reluctance of unemployment to fall?
  5. Why might a fall in wages end up being contractionary?
  6. What lessons can be learned from the Great Depression about cures for unemployment?
  7. How might unemployment be brought down in the USA?
  8. Why may making wages somewhat more flexible, as opposed to perfectly flexible, not be a good thing?

Here’s an interesting example of oligopoly – one you probably haven’t considered before. It’s the art market. And it’s not just one market, but a whole pyramid of markets. At the bottom are the ‘yearning masses’ of penny-poor artists, from students to those struggling to make a living from their art, with studios in their attic, garden shed or kitchen table. At the top of the pyramid are those very few artists that can earn fantastic sums of money by selling to collectors or top galleries. Then there are all the layers of markets in between, where artists can earn everything from a modest to a reasonable income.

The pyramid is itself depicted as a work of art, which you can see in the linked article below. It’s worth studying this piece of art carefully as well as reading the article.

Questions

  1. Identify the increasing barriers to entry as you work up the art market pyramid.
  2. Are there any other market imperfections in the art market that you can identify from the diagram?
  3. What are the key differences between the ‘primary market, tier 1’, the ‘primary market, tier 2’ and ‘the secondary market’?
  4. Are artists ‘rational maximisers’? If so, what is it they are trying to maximise? If not, why not?
  5. How would you set about determining the ‘worth’ of a piece of art? How do possible future value of a piece of art determine its present value?

With government cuts and pay freezes, many people are worried about their future. Against this background it’s little wonder that people are growing increasingly resentful about the soaring pay of bankers and other leaders of major companies – especially when they reflect on the behaviour of top bankers who were largely responsible for the recession in the West and the debt problems that resulted. And the gap between those at the top and workers on average pay just goes on widening. As the final article below states:

The boss who sells Cillit Bang got paid a hefty £92.6m last year, while his counterpart who builds executive homes pocketed £38.4m and a top miner took home £27m. These are not figures from some international football league, but the bosses of Britain’s biggest companies, who received an average 55% pay rise in the year to June. A top FTSE 100 boss now earns £4.9m – 88 times the average worker’s pay.

On 9 November 2010, a high pay commission was launched to investigate the yawning pay gap between top executives and those on average incomes.

As the high pay commission, set up by the thinktank Compass and backed by the Joseph Rowntree charitable trust, begins its year-long analysis into the widening gap between the lowest and highest paid, a Compass poll shows that 99% of people believe that top executives are overpaid.

The commision will seek answers to questions such as the following: Why has the gap widened so massively? What is the role of globalisation in the process? Why has competition not worked to compete top pay down? Why don’t company owners impose more restraint on executive pay? Is there a form of collusion to push executive pay ever higher? Are executives worth it?!
