Al Gore’s contribution to the global climate change debate is not in question and he has, along with the IPCC, been awarded the 2007 Nobel Peace Prize for his work in raising awareness. If you haven’t seen his film “An inconvenient truth” then do get hold of the DVD – it may just be the most interesting PowerPoint presentation you will ever see! However, does he really understand the nature of the debate? The article below suggests that he has not yet taken account of the most fundamental trade-off in dealing with climate change – the trade-off between our own quality of life and that of our descendants in the future.

Save the earth in six hard questions MSN Slate (22/10/07)

Questions

1. Explain what is mean by a trade-off “between the quality of our own lives and the quality of our descendants’ [lives]”.
2. What is meant by the term ‘risk-averse’ and how is this relevant in the climate change debate?
3. Consider the questions raised by the article. Discuss how relevant the conclusion reached is in the light of these questions.

The rapid growth in the use of overseas and agency staff for many lower paid jobs has been a contentious issue for many in the trade union movement. Unions have demanded the same rights for agency staff as for permanent staff, but the government is reluctant to do this, arguing that the use of agency staff encourages flexibility in the workforce.

Questions

1. Explain the impact that the use of agency staff has on the supply curve for labour. (N.B. You should consider both the position and shape of the curve in your answer.)
2. Discuss the government’s view that “the flexibility provided by agency workers has been a vital part of Britain’s economic success“.
3. Discuss the impact on the UK labour market of giving agency staff the same employment rights as permanent staff.

The UK and global labour markets are changing significantly. In the UK we have faced a level of immigration of around 500 – 600 thousand people (the government does not know the exact figure), while in the global economy the International Monetary Fund (IMF) has estimated in its latest World Economic Outlook that the global labour force has quadrupled in the last quarter of a century. So what is the impact on the UK labour market? Many assume that the effect is negative, but as is always the way with these things, you will find plenty of economists who will argue the opposite. The article below from the Times Online looks at these national and global issues.

Migrants create job market slack Times Online (20/5/07)


Questions
1. Using diagrams as appropriate assess the impact of recent immigration on the UK labour market.
2. Discuss the extent to which changes in the global labour force and UK immigration have affected the level of wages in the UK labour market.
3. Discuss the extent to which the global labour force is likely to change in the next decade.

During the period that Mrs Thatcher was in office, the post-war trend towards greater equality of income was reversed. Although some of the changes the Labour government has made since 1997 have helped those on lower incomes, the rise in incomes at the top of the scale has meant that the gap between rich and poor has widened again. The article below from the Guardian looks at the latest figures on income inequality.

Inequality at same level as under Thatcher Guardian (18/5/07)


Questions
1. Define the terms (a) Lorenz curve and (b) Gini coefficient.
2. Given the changes in income distribution outlined in the article, discuss how the value of the Gini coefficient has changed since 1997.
3. Draw Lorenz curves to show the changes that have taken place in income distribution during Mrs Thatcher’s period in office and during Tony Blair’s time in office.
4. Analyse two policies that the government could introduce to reverse these income distribution trends.

The national minimum wage will rise again in October 2007 by about 3% from £5.35 to £5.52. However, the Work Foundation has warned that the effectiveness of the minimum wage may be at its limits and that further rises in its level may not have the desired impact in terms of addressing inequality. The articles and press release below consider these issues.

National minimum wage at the limits of its effectiveness The Work Foundation – press release (6/3/07)
Warning over minimum wage level BBC News Online (6/3/07)

Questions

1. Using diagrams as appropriate, illustrate the likely impact on the UK labour market of the proposed increase in the national minimum wage from October 2007.
2. Assess the arguments given by the Work Foundation that the minimum wage is reaching the limits of its effectiveness.
3. Evaluate two methods other than a national minimum wage for reducing levels of both relative and absolute poverty.
