When we examine industries and markets in economics, one of the key things we look for is how competitive the market is. A question that we ask is, under what type of market structure is this firm operating? To answer this, we will need information on the number of competitors, the products, prices, advertising, profits, efficiency and how the firms are likely to behave in both the short and long run.
A lot of the time firms are independent: their behaviour doesn’t affect the actions of rivals. This is usually because each firm within the industry only has a relatively small market share. If one firm changes the price, or how much it spends on advertising/product development, this won’t have an impact on the market equilibrium.
However, it’s not as easy for an oligopolist, as interdependence is a key characteristic of this market structure. As such, it’s not surprising that firms have a decision to make: should they compete with the other firms and try to maximise our own profits, or should they collude and try to maximise industry profits? Whilst collusion is illegal in many countries, activities such as price fixing do go ahead and it can be difficult to prove, as the ACCC is finding with a petrol price-fixing case in Melbourne. In 49 of the 53 weeks studied, when one of the big petrol stations changed their price, the industry followed these movements exactly.
As competition in a market decreases, it could be a sign that an oligopoly is developing. A few firms are beginning to dominate the market and this could spell trouble for customers. Indeed, in the Australian banking sector, there are concerns that an oligopoly will develop if more competition is not introduced. The Deputy Chairman of the Australian Bankers’ Association said: “We’ve got four major banks that are repricing all their commercial and small business customers’ margins upwards”. Customers may therefore lose out with higher prices and less choice, while the dominant firms see their profits growing.
The market structure under which a firm is operating will have a major impact on its decisions and the outcomes in the market, as shown in the articles below.

Questions
- What are the main characteristics of an oligopoly?
- Illustrate a cartel that fixes prices and show how a member of this cartel must sell at that price and at a given quantity.
- Some factors make collusion more likely to occur and more likely to succeed. In the Australian banking sector, which factors do you think are allowing price fixing to occur?
- Is the example of petrol price fixing barometric price leadership or dominant firm price leadership? Explain both of these terms and use a diagram, where possible, to illustrate the effects.
- The articles suggest that oligopolies are bad for competition. Explain why this is the case.
- To what extent are oligopolies against the public interest? Use examples from the articles to back up your argument.
In the run-up to the United Nations climate Change conference in Copenhagen from 7 to 18 December, many countries have been setting out their preliminary positions. The conference aims to set the terms for the agreement that will succeed the Kyoto Protocol in 2012.
Senior scientists, economists and politicians have been warning about the dire necessity of reaching a comprehensive agreement. One such economist is Sir Nicholas Stern. He argues that the EU should impose a unilateral cut in greenhouse gas emissions of 30% from 1990 levels by 2020, irrespective of the any agreement in Copenhagen. The EU has pledged to increase its targeted cut from 20% to 30% only if substantive progress is made at the talks.
Other countries have set out their preliminary positions. China has offered to reduce its carbon intensity by 40% (i.e. the proportion of carbon emissions to GDP); the USA has offered to reduce emissions by 17% by 2020 compared with 2005 levels; and India has offered to reduce its carbon intensity by 24% over the same period.
However, as the Washington Post article below states, “During a weekend meeting, India, along with China, Brazil, South Africa and Sudan, decided it would not agree to legally binding emission cuts, international verification of reductions without foreign funding and technology, and imposition of trade barriers in the name of climate change.”
Meanwhile the news from Australia has come as a blow to those seeking to extend tradable permit schemes around the world. The Australian senate has rejected a bill to set up an Emissions Trading Scheme (ETS), designed to cut Australia’s carbon emissions by up to 25% below 2000 levels by 2020.

Questions
- Why cannot tackling global warming be left totally to the market?
- To what extent can the market provide part of the solution to global warming?
- How can a cap-and-trade system (i.e. tradable permits) be used to achieve (a) emissions reductions; (b) an efficient way of achieving such reductions?
- Why could the atmosphere be described as a ‘global commons’? Does it have either or both of the features of non-excludability and non-rivalry (which are both features of a public good)?
- To what extent are climate change talks a prisoner’s dilemma game? How may the Nash equilibrium of no deal, or an unenforceable deal, be avoided?
On 26 November, the water industry regulator, Ofwat, published its decisions on the price caps that will apply to all the 21 water companies covering 23 areas in England and Wales from 2010 to 2015. Despite calling for average cuts of £14 in draft proposals released back in July, Ofwat is now requiring an average cut of just £3. This still means that average water prices will be some 10 per cent lower than those sought by the water companies. Note that all these figures are in real terms: i.e. after taking inflation (or deflation) into account.
But while customers in some areas will see their bills frozen in real terms, or even significantly cut, others will see a rise in theirs. The average price change varies from a fall of 7 per cent in Wales, East Anglia and Portsmouth to a rise of 13 per cent in Essex and Suffolk. There is also variation within regions, depending on factors such as whether or not you have a water meter. Thus, in the South West, customers without a meter could see a rise in bills of 29 per cent.
Not surprisingly, Ofwat’s decisions have received mixed reactions. The water companies claim that the price cap is too high to allow them to make the necessary investment in water infrastructure, such as replacing old pipes to cut down on leakages. Water customers, on the other hand, claim that Ofwat has been ‘captured’ by the industry and, as a result, has been much too lenient.
So who is right? And is the current system of 23 separate regional monopolies, regulated through price cap regulation, the best way of structuring and running the water industry? The following articles and videos look at the issues

Questions
- Is price cap regulation of the RPI–X variety the best form of regulation? Explain with reference to both incentives and the issue of uncertainty.
- Explain whether water companies are natural monopolies.
- To what extent can competition be introduced into privatised utility industries as an alternative to regulation? Is increased competition a practical alternative to price cap regulation in the water industry?
- What are the arguments for and against installing water meters in each home so that people pay per litre used rather than paying a flat charge depending on the property value?
- Explain what is meant by ‘regulatory capture’. Is there evidence of regulatory capture in the water industry? Consider with respect to the November 26 ruling.
In a recently published book, Scroogenomics, Joel Waldfogel, Professor of Business and Public Policy at the University of Pennsylvania, examines the economics of giving presents and considers whether we would be better off being Scrooges. This book brings to a general audience some of Professor Waldfogel’s work on giving. In a 1993 paper, he argued that holiday gift-giving involves a deadweight welfare loss. “I find that holiday gift-giving destroys between 10 per cent and a third of the value of gifts.” (See The Deadweight Welfare Loss of Christmas. Note: you should be able to access this from a UK university site if you are logged on.)
The core of his argument is that many gifts we give are not really what the person receiving it would have chosen. If you give someone a gift costing £10 for which the person would not have paid more than £6, then that is £4 wasted – a deadweight loss of £4.
So should we all be Scrooges and stop giving? Think of all money that would be saved and which could be spent on things that were more wanted. But wait a minute. What about the pleasure (i.e. utility) of giving? And what about the pure pleasure of receiving a gift, irrespective of the gift itself? Should these be added in to arrive at the total utility? Then there is the pleasure (or hassle) of shopping for the gift. Shouldn’t this be taken into account too? In other words, to establish deadweight loss, we need to take into account all the pleasures and displeasures of the process of giving and receiving.
Finally there is the question of whether better research on the part of the giver into the tastes of the receiver would enable them to choose more wanted gifts. Or should we simply give cash or gift tokens: at least these can be used by the recipient for whatever they choose?

Questions
- What factors would need to be taken into account in attempting to measure the true deadweight loss of giving? Would this involve inter-personal comparisons of utility and, if so, what problems might arise from this?
- Examine whether it is better to give cash or gift tokens rather than a physical gift?
- Consider whether charitable donations would be the best form of gift to a friend or relative?
- One practice used in many families is the ‘secret Santa’. This is where everyone in the family secretly draws the name of another family member at random. They then buy a gift for this person and put the gift under the tree (or in a box). Thus each person gives just one gift and receives one gift and nobody knows who has given them their gift. Normally a maximum value of the gift is determined in advance. Consider the advantages and disadvantages of such as system. Is it a more efficient way of giving?
- What are the macroeconomic arguments for giving presents at Christmas time or at other festivals?
No-one in the UK can have failed to notice the seemingly never-ending torrent of wind and rain that has swept the country over the past couple of weeks. At the moment, there are 19 flood warnings in the UK and a further 58 areas are on flood watch, according to the Environmental Agency. Cockermouth in Cumbria has been the worse hit, with 12.4 inches of rain falling in just 24 hours, 6 bridges collapsing and over 200 people being rescued by emergency services, some having to break through their roof to get out. Thousands of people have been evacuated; PC Bill Barker lost his life trying to save others; and fears remain for a 21-year old women, who was washed away from a bridge. This has led to a safety review of all 1800 bridges in Cumbria.
Thousands of people have lost their homes and belongings and over 1000 claims to insurance companies have already been made. Flood victims are facing rapidly rising costs, as insurance premiums increase to cover the costs of flooding and this has led to these houses becoming increasingly difficult to sell. Some home-owners are even being forced to pay mandatory flood insurance. Without this in place, insurance companies are not willing to insure homeowners in some areas, or the premiums they’re charging are simply unaffordable. After all, if one household in an area hit by flooding claims for flood damage, the probability of all other houses in that area also claiming is pretty high, if not an almost certainty.
Care packages are arriving for those hit by the floods, as food is starting to run out, and estimates of the costs of flooding have already reached ‘tens of millions of pounds’. Gordon Brown has pledged £1 million to help the affected areas, but who knows where this money will come from; Barclays has also pledged help for the small businesses affected.
An independent inquiry needs to be launched into the causes of this flooding and whether better flood protection should have been in place. However, the extent of the flooding experienced is argued to only happen every 300 years, so is the cost of flood protection really worth the benefits it will bring? A number of issues have arisen from this freak weather, and some are considered in the articles below.

Questions

- Are the risks of flooding independent?
- Apart from those living in the areas hit by floods, who else will suffer from the flooding and how?
- The flooding experienced is said to be a phenomenon experienced every 300 years. Should better flood defences be put into place to stop the same thing happening in the future or should we use the necessary money elsewhere?
- What are the private and external costs and benefits of increased flood defences? What would a cost–benefit analysis need to establish in order for a decision to be made over whether more defences should be put in place?
- Millions of pounds will be needed to repair the damage caused by the flooding. Where will this money come from? Think about the opportunity cost.
