Tag: price elasticity of demand

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.

Questions

  1. Using a diagram, explain how a minimum price control on alcohol will work. What are the likely effects?
  2. Which factors will determine the effectiveness of the minimum price?
  3. Why is it that ‘binge drinkers’ may not be responsive to the higher price?
  4. The Mirror article refers to ‘loss leaders’. What are they and how are they relevant here?
  5. What other policies could be used to tackle binge drinking?
  6. Given that taxes on products such as alcohol and cigarettes raise so much tax revenue for the government, would there be an adverse effect by raising the minimum price on alcohol?

  8. Is alcohol a de-merit good? Why is it an example of market failure?

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.

Questions

  1. What type of tax is VAT? Illustrate the effect of such a tax on a diagram and explain why the higher the price of the good, the bigger the impact of the VAT rise. How might this impact inflation?
  2. Why are car sales expected to fall in the UK over the coming year? Given this expected trend, what might we expect to see in terms of car prices?
  3. What impact might rising petrol prices have on new car purchases? What figure would you expect to see for cross elasticity of demand?
  4. How might the expected decline in car sales affect the UK economy over the next 12 months?
  5. What type of market structure is the car industry? (Think about the characteristics of monopolistic competition and oligopoly.)

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.

As students, many of you probably have a student identification card, which you might use when you go to the cinema or when you buy something in a shop offering student discounts. Your parents or grandparents, if they are 60 or over, may get similar discounts, and your younger siblings or nieces and nephews may pay nothing for certain services.

It doesn’t cost a cinema more to provide a seat for an adult than it does for a child, a student or a senior citizen. So, why is it that firms can charge different groups of consumers different prices, even though they are consuming the same good or service? We are, of course, referring to the ability of a firm to price discriminate. The following short cases look at the concept in action.

  5. What forms of price discrimination (a) are being practised by US private universities and (b) being proposed in the Browne report for students at English universities?
  6. What other examples of price discrimination can you think of? Try and think of examples that fit into the different types of price discrimination.

Rising costs of cloth and a rise in VAT could mean that clothes prices are set to rise. Does this spell the end of cheap fashion from the likes of Primark and H&M? Or can they absorb the cost increases?
