Oil prices have been rising in recent weeks. At the beginning of October 2010, the spot price of Brent Crude was $80 per barrel. By December it has passed $90 per barrel. There is some way to go before it gets to the levels of mid-2008, when it peaked at over $140 per barrel (only then to fall rapidly as the world slid into recession, bottoming out at around $34 per barrel at the end of 2008).

Higher oil prices are a worry for governments around the world as they threaten higher inflation and put recovery from recession in jeopardy. You will probably have noticed the higher petrol prices at the pumps. If you spend more on petrol, you will have less to spend on other things.

So why have oil prices risen and are they likely to continue rising? The following articles examine the causes of the recent surge and look ahead to the likely response from OPEC and the path of oil prices next year.

You will probably have come across the concept of consumer sovereignty. In the mythical world of perfect markets, producers are at the beck and call of consumers. Firms that are not responsive to consumer demand go out of business. In other words, in order to survive they have to respond to any shifts in consumer demand. These in turn can be the result of changes in tastes, changes in income, changes in the prices of other goods, and so on.

Of course, the real world is not perfect, but it is still often assumed that consumers are powerful in influencing what firms sell and at what prices. Well, firms would much rather be in a position of manipulating consumer tastes and hence the huge amounts spent on advertising and marketing.

And it doesn’t end there. Firms use many pricing practices which, to put it mildly, try to confuse consumers or lure them into buying things by making them think they are getting something much cheaper than they really are. Take the case of airline tickets. Some budget airlines offer tickets at extremely low prices, such as 99p. But if you select such a flight, by the time you get to the final screen where taxes, charges, supplements, luggage, etc. are added, the price could exceed £100! And ask yourself this, when you buy something with 20% off, or when you buy ‘three for the price of two’ how rational was your decision? Did you really want the product? Was the offer really ‘genuine’?

The Office of Fair Trading has recently completed two investigations into pricing. As it stated 14 months ago when the investigations were launched:

The first, into online targeting of advertising and prices will cover behavioural advertising and customised pricing, where prices are individually tailored using information collected about a consumer’s internet use. It is expected that this study will be completed by spring 2010.

The second, into advertising of prices, will consider various pricing practices which may potentially mislead consumers. The study will look in particular, but not exclusively, at how these practices are used online.

The following articles look at some of the practices that firms use to drive sales – practices that deliberately attempt to manipulate the consumer. The assumption of ‘perfect knowledge’ by consumers may be a long way from the truth.

A two-week international climate change summit opened in Cancún, Mexico, on 29 November. But will the talks make any progress in tackling global warming? Will mechanisms be put in place to ensure that the previously agreed ceiling of 2°C warming is met?

After the largely unsuccessfuly talks in Copenhagen a year ago, hopes are not high. But a likely rise in global temperatures of considerably more than 2°C could have disasterous global consequences. Indeed, new evidence suggests that even a ceiling of 2°C may be too high and that, as temperatures rise towards that level, domino effects will start that may become virtually unstoppable. As Andrew Sims in the Guardian article notes:

This is the problem. Once the planet warms to the point where environmental changes that further add to warming feed off each other, it becomes almost meaningless to specify just how much warmer the planet may get. You’ve toppled the first domino and it becomes virtually impossible to stop the following chain of events. Honestly, nobody really knows exactly where that will end, but they do know it will end very, very badly.

The following podcasts and articles look at the importance of reaching international agreement but the difficulties of doing so.

There has been a 38% increase in profit margins made by energy companies in the last 2 months and it is this which has prompted an investigation by Ofgem, the electricity and gas market regulator in the UK. Alistair Buchanan, Ofgem’s chief executive, said:

“With Britain facing an investment bill of £20bn over the next 10 years, consumers have the right to expect that the energy retail market is providing them with value for money. Our analysis published today shows an increase in company margins from £65 to £90 at a time of rising energy prices, which causes Ofgem to rightly ask if companies are playing it straight with consumers.”

Three of the big six suppliers have recently announced price rises and the fast-track review by Ofgem will consider whether consumers should be better protected. Scottish Power has increased gas prices by 2% and electricity prices by nearly 9%, meaning some customers may pay an extra £138 per year. British Gas is also planning on raising prices from December 10th, with gas and electricity bills expected to increase by 7%. Scottish and Southern Energy said it will increase domestic gas tariffs by 9.4%. EDF has promised a price freeze – at least until after the winter and nPower and E.ON are yet to announce their plans, but we can expect some form of a price rise.

While the review won’t make any difference to customer bills in the short term, Ofgem does have the power to make some changes to the way the companies are run. It is also expected that Ofgem will ask for more legislative support from the government and the Competition Commission. Although there are several suppliers in the energy market, each has market power and their dominance is preventing new firms from entering. As Adam Scorer, Director of Reputation and Impact at Consumer Focus, said:

“They do not feel the hot breath of competition on their necks.”

The owner-occupied housing market has seen widespread coverage. With house prices falling throughout the recession and problems accessing mortgages for many people, it is this sector of housing that has received most attention. However, it is rental homes that we’ll be considering here and a new strategy being adopted by landlords. As access to mortgages dried up, people instead turned to renting. Demand for rental properties began to increase, such that competition between potential tenants increased significantly. Not only has there been a substantial increase in rents – up by some 35%, but it has also led to a new ‘sealed bid’ strategy.

A strategy that is often used for purchasing houses is where potential buyers submit sealed bids and it is this approach which is now spreading to the rental sector, as demand and competition for properties increases. Potential tenants are required to submit a sealed bid, containing the amount that they are willing to pay to rent out the property and all this must be done within a deadline. Whoever submits the highest bid ‘wins’ the property and hence tenants are encouraged to submit a bid at or close to the maximum they are willing to pay. Landlords insist that they are not trying to force tenants to pay more, but that it is simply the most effective way of letting properties that are short in supply, but face significant demand. As the BBC News article states:

‘It seems that with the current state of the housing market, sealed bids will be here to stay – as long as many would-be renters are chasing a dwindling supply of good rental homes.’

Questions

  1. Using a supply and demand diagram, explain the trend we have seen in the rental market, thinking about the impact on demand, supply and hence on price. How does this explain why sealed bids have been used to combat the increased competition?
  2. Which factors have affected (a) the demand for rental properties and (b) the supply of rental properties? How is the elasticity of demand and supply relevant here in terms of the impact on price?
  3. To what extent is a sealed bid format fair on potential tenants? Who does such a strategy favour?
  4. How could this sealed bid strategy be an example of price discrimination?
  5. What is likely to happen to your consumer surplus if you have to submit a sealed bid?
