If we are faced with simple and limited choices, we may make careful decisions based on a number of criteria: in other words, we will identify various characterisitics we are looking for and see how well the various alternative products or activities meet our criteria. When we have lots of choice, however, we may be less careful or get confused.

In this Guardian podcast, the panelists discuss complex choices between many products and/or characteristics. Are people being ‘rational’ when making such choices? Is being less careful simply a rational use of scarce time? Do people really want lots of choice or would they prefer more limited choice? Can experiments where people are given choices help us to understand how people choose and how much choice businesses or government should give people? Then there is the question of producers/suppliers of products. Does choice promote competition and product development and is there an optimum amount of choice to achieve this?

The Business: Choice Guardian Podcasts, Sheena Iyengar, Julian Glover and Andrew Lilico in conversation with Aditya Chakrabortty (1/9/10)

Questions

  1. Are people ‘rational’ when they make choices? For what reasons may they not be rational?
  2. Can you make rational choices if your information is imperfect?
  3. Is there an optimum amount of choice and how would you set about establishing that optimum?
  4. How useful are experiments in understanding the process of choice? What are the weaknesses of such experiments?
  5. Should people be limited in the amount of choice they are given over medical treatment and schools?
  6. What are the advantages to other people of giving people more choice?
  7. How much does culture influence our attitudes towards choice?

Here’s an exciting bit of news. Lake Eyre in South Australia is filling and the Lake Eyre Yacht Club’s sailing regatta started on 5 July. So what, you may ask! Well, Lake Eyre is in the middle of one of the driest deserts in the world. It virtually never rains there and most of the time, the ‘lake’ is one huge dry salt pan.

But just a few times per century, the rainfall many kilometres away is heavy enough to fill the dry river beds of Cooper Creek, Finke River, Georgina River and Diamantina River. These ‘rivers’ drain about one sixth of the whole of Australia (about the size of Germany, France, Italy combined) – but a sixth where rainfall is normally very low. But this season’s rains have been exceptionally high; the rivers are flowing – and the lake is filling.

When the lake does fill, it teems with life. Fish eggs that have lain buried in the salt for years hatch. Sea birds fly in nearly 1000 kilometres from the Southern Ocean. And it’s then that the enthusiasts come to play.

What’s this got to do with economics? Well economics is about scarcity and choice. Many of the choices we make are not simple buying and selling choices. Many clubs and other organisations thrive on the enthusiasm of their members. They’re not there to make money but certainly add to people’s ‘utility’. And enthusiasm, and hope, is what the members of the Lake Eyre Yacht Club have in abundance. Let’s hope they get lots of utility from sailing in the desert over the coming weeks.

Questions

  1. What attitude do the members of Lake Eyre Yacht Club have towards risk and uncertainty?
  2. How would you set about estimating the consumer surplus that members are likely to gain from attending the regatta and sailing on the lake?
  3. How price elastic would you expect the demand for and supply of services to be, such as ferry crossings and accommodation?
  4. What business opportunities are likely to be associated with sailing on the lake? Would it be ‘rational’ to set up such a business?

Below you will find links to the manifestos of the three main UK-wide parties for the general election on May 6. It’s not our role to suggest to those of you living in the UK with the right to vote how you should vote. The one thing we would suggest is that you consider carefully what the parties are proposing.

What is clear is that the state of the economy and the policies necessary to tackle economic problems are central to all the manifestos. As a student of economics, you should be able to assess the manifestos in terms of how the parties set out the economic problems facing the UK and what they propose doing about them.

So look through the manifestos below and then answer the questions we’ve posed about the UK economy and about the economic policies being proposed. If you are uncertain about how to answer them, then ask yourself what extra information would I need to enable me to give a good answer.

The manifestos (in alphabetical order)
The Conservative Party manifesto
The Labour Party manifesto
The Liberal Democrat Party manifesto

Other sources
We are reluctant to recommend newspaper articles, as all newspapers at election time tend to be highly partisan and are therefore likely to give you a very specific ‘spin’ on the parties’ proposals. Perhaps the two best independent sources are the BBC and the Institute for Fiscal Studies. See:
Election analysis 2010 Institute for Fiscal Studies
Election 2010 BBC News
Stephanomics Stephanie Flanders’ blog (this links to the archive).

Questions

  1. How do the analyses of the economic problems facing the UK differ between the three manifestos?
  2. Compare the policies of the three parties for cutting the public-sector deficit. Consider the following issues: the size and nature of any cuts in government expenditure; the size and nature of any tax increases; the timing of the meaures.
  3. What assumptions are being made about the determinants of aggregate demand over the coming months and the role of fiscal policy in this?
  4. Compare the policies of the three parties towards the distribution of income. To what extent have the parties taken into account possible incentive/disincentive effects of policies of redistribution?
  5. To what extent are the parties proposing using the tax system to tackle problems of externalities? Give examples and assess how effective the policies are likely to be.
  6. To what extent do each of the manifestos leave you with unanswered questions about the economy and how their proposed policies will tackle economic problems?

Transport issues in the UK are always newsworthy topics, whether it is train delays, cancelled flights, the quality and frequency of service or damage to the environment. Here’s another one that’s been around for some time – high-speed rail-links. Countries such as France and Germany have had high-speed rail links for years, but the UK has lagged behind. Could this be about to change?

The proposal is for a £30bn 250mph high-speed rail link between London and Birmingham, with the possibility of a future extension to Northern England and Scotland. This idea has been on the cards for some years and there remains political disagreement about the routes, the funding and the environmental impact. Undoubtedly, such a rail-link would provide significant benefits: opening up job opportunities to more people; reducing the time taken to commute and hence reducing the opportunity cost of living further away from work. It could also affect house prices. Despite the economic advantages of such a development, there are also countless problems, not least to those who would be forced to leave their homes.

People in the surrounding areas would suffer from noise pollution and their views of the countryside would be changed to a view of a train line, with trains appearing several times an hour at peak times and travelling at about 250mph. Furthermore, those who will be the most adversely affected are unlikely to reap the benefits. Perhaps the residents of the Chilterns would be appeased if they were to benefit from a quicker journey to work, but the rail-link will not stop in their village. In fact, it’s unlikely that they would ever need to use it. There are significant external costs to both the residents in the affected areas and to the environment and these must be considered alongside the potential benefits to individuals, firms and the economy. Given the much needed cuts in public spending and the cost of such an investment, it will be interesting to see how this story develops over the next 10 years.

Questions

  1. Make a list of the private costs and benefits of a high-speed rail link.
  2. Now, think about the external costs and benefits. Try using this to conduct a Cost-Benefit Analysis. Think about the likelihood of each cost/benefit arising and when it will arise. What discount factor will you use?
  3. There are likely to be various external costs to the residents of the Chilterns. Illustrate this concept on a diagram. Why does this represent a market failure?
  4. How would you propose compensating the residents of the Chilterns? Are there any problems with your proposal?
  5. Will such a rail link benefit everyone? How are the concepts of Pareto efficiency and opportunity cost relevant here?
  6. To what extent would this rail link solve the transport problems we face in the UK. Think about the impact on congestion.

Paul Samuelson, who died on 13 December at the age of 94, was one of the greatest economists who ever lived. A generation of economics students had their first exposure to the subject through his textbook, Economics, first published in 1948 and now in 19th edition. His research covered many topics in economics and he brought a rigour to economic analysis that has had a profound influence on the development of the subject.

Tributes have flowed in from around the world and many obituaries have been written. The following is a selection that give you a feel for the huge contribution he made to the subject.

Thinking about his achievements, try answering the question below.
