Imagine putting together a dream team of economists to tackle the current recession. Who would you choose? Larry Elliott, the Guardian’s economics editor considers this game of ‘fantasy economics’ in the linked article below. In the process, he makes a number of criticisms of economists for saying little about what caused the current crisis and how such crises could be avoided in the future.
As students studying economics you might want to defend economists against this attack. After all, virtually every time you turn on the radio or television or open a paper, there are economists explaining what has happened and what should be done about it. So see if you can mount a defence against this attack – and maybe put together your own dream team of economists!
It’s a funny old game: where is the dream team of economists to tackle the slump? Guardian (1/6/09)

Questions
- Explain why economies with deregulated financial markets are likely to experience macroeconomic instability (‘boom-bust cycles’).
- What are the benefits of studying perfectly competitive markets and general equilibrium theory?
- Write a brief defence of the use of mathematics in economics.
- Does experimental economics allow economists to take a ‘more nuanced and relevant approach’ to studying economic behaviour and devising appropriate policy?
Until changes in their governments, both the USA and Australia were unwilling to sign up to the Kyoto Treaty on climate change. But things are changing. In both countries, cap and trade bills have been proposed by their administrations (see A changing climate at the White House). In the USA, President Obama’s bill would see the imposition of carbon quotas aimed at achieving a reduction in greenhouse gas emissions by 2020 of 17 per cent, with emissions trading allowing an efficient means of achieving this. In Australia, Kevin Rudd’s Labor government plans to introduce quotas and emissions trading in 2011 to achieve a 25 per cent reduction in greenhouse gases by 2020.
But are there lessons to be learned from the European Emissions Trading scheme? The following articles look at some of the issues.

Questions
- Discuss the merits and problems of cap-and-trade systems for reducing carbon emissions in an efficient and effective way.
- Is the price of carbon a useful indicator of the success or otherwise of cap-and-trade schemes to reduce greenhouse gas emissions?
- In what ways does the current recession (a) aid, and (b) hinder the introduction of tougher schemes to tackle global warming?
The following articles look at a recently published book by George Akerlof of the University of California, Berkeley, and Robert Shiller of Yale. They examine the role of what Keynes called ‘animal spirits’ and is the title of the book.
The motivation to make economic decisions (to buy, to sell, to invest, etc) may not be ‘rational’ in the sense of carefully weighing up marginal costs and marginal benefits. Rather it can be one of over-optimism in good times or over-pessimism in bad times. Just as individuals have ‘mood swings’, so there can be collective mood swings too. After all, confidence, or lack of it, is contagious. This motivation that drives people to action is what is meant by animal spirits.
But are animal spirits a blessing to be nurtured or a curse to be reined in? Should governments seek to constrain them?

Questions
- Describe what is meant by ‘animal spirits’ and their effects on human behaviour.
- Why may animal spirits make economies less stable?
- How may animal spirits help to explain exchange rate overshooting?
- Discuss whether governments should seek to constrain animal spirits and make people more ‘rational’? Also consider what methods governments could/should use to do this?
In a major break from the policy of the Bush administration, President Obama has announced that the US government will regulate greenhouse gas emissions. The US Environmental Protection Agency has found that CO2 emissions pose a ‘threat to public health and welfare’. This finding allows regulation to be imposed.
At the end of March the Democrats in the House of Representatives released a draft climate change Bill. Central to this would be a system of tradable permits. ‘Under this program, covered entities must have tradable federal allowances for each ton of pollution emitted into the atmosphere.’ (See 4th article below.)

Questions
- To what extent is the EPA ruling compatible with the bill proposed by the Democrats?
- Is a ‘cap-and-trade’ system (i.e. tradable permits) the best way of dealing with climate change?
- What lessons can the USA draw from the European Emissions Trading Scheme in designing its own tradable permits scheme?
The ‘tragedy of the commons’ refers to the overuse of common land. If people can freely graze their animals on such land and have no responsibility for maintaining it, then the land will be overused and everyone will suffer. The problem is that the benefit of using the land occurs to the individual whereas the cost is collectively incurred.
There are many modern examples of the tragedy of the commons and the articles below look at some of them. Perhaps surprisingly, not all cases of the use of common resources end in tragedy; some common resources are used sustainably. A more thorough analysis must involve deeper questions of human motivation and behaviour.

Questions
- Explain how the tragedy of the commons arises and give some examples other than common grazing land.
- How and why does the tragedy of the commons occur in information technology? Consider the benefits and costs of the ‘fix’ to the problem advocated in the first linked article.
- Does the case of Wikipedia (see the third linked article) disprove the proposition that common resources will be overused?
- To what extent is free access to content (music, newspapers, videos, books, etc.) a tragedy of the commons? Is the only solution to devise an effective charging model that rewards content creators?
