A huge majority of the British population are in agreement on one thing: UK drinking is out of control. At a cost to the NHS of over £2 billion per annum, it’s quite obvious that the current ‘binge drinking’ culture is unsustainable for those doing the drinking and for the NHS.

This issue was raised back in January 2010, when the Labour government came under pressure to impose a minimum price on alcohol. (see All-you-can-drink bans) The report published in early January suggested that a minimum price on alcohol of 50p per unit would save more than 3000 lives per year. Dr. Richard Taylor said:

“The evidence we took showed that minimum pricing was the most effective way forward and at the moment you can sometimes buy beer cheaper than water. Our message is that the price would be put up but only by a little for moderate drinkers. Surely that is a sacrifice to pay for the good health of young people.”

The Coalition’s plan is to introduce a minimum price for alcohol, which would increase the price of a can of lager to a minimum of 38p and a litre bottle of vodka would be a minimum of £10.71. By increasing the price of alcohol, it is hoped that demand will be reduced and this will go some way to tackling the problem of binge drinking.

However, many argue that the proposal will be ineffective. Some believe that the minimum price is not high enough and that such a small increase will have no effect. Others argue that it will only affect small supermarkets and will have a significantly adverse effect on pubs, which are already struggling. Furthermore, a concern is that by raising the price of alcohol, the only people who will suffer are the so-called ‘sensible’ drinkers. Those who go out and binge drink will be largely unresponsive to the higher price.

For most people, buying a new car is a luxury and in times of hardship it is a luxury that many cannot afford. Sales of new cars did grow during 2010 by 1.8% compared to the previous year, although the end of the car scrappage scheme in March 2010 did see a fall in sales. Sales went from being 19.9 per cent up on 2009 in the first half of the year, to being 13.8 per cent down for the remainder of 2010. On top of this, they are predicted to fall by some 5% over the coming 12 months.

Part of the explanation of this trend is the VAT rise. While an extra 2.5% is hardly noticeable on many every day items (as we saw when VAT was reduced to 15%), it will have a much larger effect on more expensive items, such as cars.

It was expected that people thinking of buying a new car would try to beat the VAT rise and so car firms hoped for a surge in sales during December. However, this did not occur and with VAT at 20% during 2011, car prices will rise: a £15,000 car will cost an extra £320. Another contributing factor to the lower than expected sales in December was the snow. Retail sales in December collapsed by 37.5%, where as fleet sales, which are less likely to be affected by the adverse weather rose by 5.1%. Similar patterns were seen in Spain, Italy and France, but in Germany sales were up by 7% on the year from December 2009.

The good news for the UK car industry is that the second half of 2011 is expected to see growth, so there may be some recovery. Furthermore, UK-built cars have seen a rise in sales – up by 17%. Finally, as petrol prices continue to rise, it is hoped that this might encourage people to trade in their less efficient old cars for more fuel-efficient new cars. This will certainly be an industry to watch over the next few months.

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.

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?

The prices of grains and other foodstuffs are rising rapidly. Wheat prices rose some 40 per cent in July and have continued to rise rapidly since. In June wheat futures were trading at around 450 US cents/bushel. By early September, they were trading at around 700 US cents/bushel. Global food prices generally rose by 5% over the two months July/August. And it’s not just food. Various other commodity prices, such as copper and oil, have also increased substantially.

At the beginning of September there were three days of food riots in Mozambique in protest against the 30% rise in the price of bread. Seven people were killed and 288 were injured. On 2 September Russia announced that it was extending a ban on wheat exports for another 12 months following a disastrous harvest. In Pakistan, the floods have destroyed a fifth of the country’s crops. Drought in Australia and floods in the Canadian prairies have reduced these countries’ grain production.

In response to the higher prices and fears of food riots spreading, the United Nations has called a special meeting on 24 September to bring food exporters and importers together to consider “appropriate reactions to the current market situation”. And yet, although global cereal production is down by some 5% on last year, it is still predicted to be the third largest harvest on record.

So what is causing the price rises? Is it simply a question of the balance of supply and demand and, if so, what has caused the relevant shifts in supply and/or demand? And what role does speculation play? The following articles look at the issues and at the outlook for commodity prices over the coming months.

Clearly changes in commodity prices affect the rate of inflation. The news item (Bank of England navigates choppy waters) amongst other issues looks at the outlook for inflation and the various factors influencing it.
