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?
There has been much discussion recently on the use of fiscal policy to combat recession. What measures should be used? How effective will they be? How will the resulting large budget deficit be brought back into balance in the future?
But what are the microeconomic implications of all the tax changes? Are the changes fair? What implications do they have for incentives? Perhaps it’s time for a completely fresh look at the structure of our tax system – a system that has been changed piecemeal over the past years to meet short-term macroeconomic and political goals. Can it be redesigned to meet the two microeconomic goals of efficiency and equity? The following article looks at what form a redesigned tax structure might take.
Our tax system is a mess. But Darling has a chance to fix it. (Peter Wilby) Guardian (11/4/09)
Questions
- In what ways does the present tax system fail to meet the goals of (a) fairness through redistribution and (b) creating appropriate incentives?
- Explain what is meant by “The whole system has been framed by Tory thinking to assist social engineering, Tory style”.
- Provide a justification and critique of the reforms proposed in the article.
Nationalisation has been coming back into fashion lately with the UK bank bail-outs. In other parts of the world though, it has been back in fashion for longer and the articles below look at two recent cases in Latin America: the nationalisation of the Chaco energy company and the renationalisation of Spanish-owned airline, Aerolineas Argentinas (AA).

Argentina renationalises airline BBC News Online (18/12/08)
Questions
- Explain what is meant by nationalisation.
- Discuss the arguments for and against nationalising (a) an airline and (b) an energy firm.
- Assess why nationalisation has become more prominent in the media recently than privatisation.
- Discuss the arguments for and against privatisation.
Somali pirates have been much in the news recently with their high profile captures of oil tankers and other ships. The impact on shipping in the area is clear and this has disrupted trade in the region, but an unforeseen impact has been on the total worldwide catch of tuna. The Indian Ocean is one of the richest sources of tuna in the world and the pirate activity has led to a fall of around 30% in the total tuna catch.
Somali piracy ‘reduces tuna haul’ BBC News Online (22/1/09)
Questions
- Using diagrams as appropriate, show the impact of Somali pirate activity on the market for tuna.
- Suggest likely values for the price elasticity of demand and supply of tuna. Analyse the extent to which these values are likely to affect the price rise in the market for tuna.
- What substitutes are available for tuna? Assess the extent to which the availability of substitutes will affect the rise in the price of tuna.
An ongoing debate in economics for many years has been the extent to which governments should intervene in the economy. The debate has re-emerged in recent months with the global financial crisis as many commentators have arged that had a tighter regulatory system been in place, it could have helped to prevent some of the poorer lending practices of banks internationally. Even the recent G20 meeting (dubbed Bretton Woods II by some analysts) discussed regulatory reform of the international financial system. The two articles below look at this debate about the extent of government intervention from two very different angles. The first is from the perspective of Victorian England and Little Dorritt, while the second (by Peter Mandelson) looks at how globalisation and the financial crisis have informed the debate about state intervention.
So much for ‘late’ capitalism Guardian (24/11/08)
The future active state Guardian (4/12/08)
Questions
- Examine the advantages and disadvantages of greater state intervention in an economy.
- Discuss the extent to which globalisation has changed the need for the amount of state intervention in an economy.
- “Strong social welfare systems and redistribution can be contributors to economic growth.” Discuss the extent to which this statement will always hold true.
