Skin cancer is on the increase in the UK. Calls are thus being made by both retailers and cancer charities for a cut in VAT on sun cream.
At present the VAT rate on sun cream in the UK is the standard rate of 17.5%, which is due to increase to 20% in January 2011. But would cutting the rate to 5%, as is being proposed, be effective in cutting skin cancer rates? What information would you, as an economist, need to assess this claim?

Questions
- What would determine the incidence of a cut in VAT on sun creams between consumers and retailiers?
- If there were a 50:50 incidence of a VAT cut between consumers and retailers and the VAT was cut from 17.5% to 5%, what percentage fall in the retail price would you expect?
- Assume that the price elasticity of demand for sun cream is –1 and price elasticity of supply is +1, how much would sales of sun cream rise if the VAT rate fell from 17.5% to 5%? Are these realistic values for the price elasticity of demand and supply?
- Under what circumstances may promoting the use of sun creams encourage the development of skin cancer?
- Are people being rational if they choose to expose themselves to the sun for long periods in order to receive a ‘fashionable’ tan? How are time preference rates (personal discount rates) relevant here?
- What market failures are involved in the tanning industry? If the use of sunbeds contributes towards skin cancer, should they be banned?
Here’s an exciting bit of news. Lake Eyre in South Australia is filling and the Lake Eyre Yacht Club’s sailing regatta started on 5 July. So what, you may ask! Well, Lake Eyre is in the middle of one of the driest deserts in the world. It virtually never rains there and most of the time, the ‘lake’ is one huge dry salt pan.
But just a few times per century, the rainfall many kilometres away is heavy enough to fill the dry river beds of Cooper Creek, Finke River, Georgina River and Diamantina River. These ‘rivers’ drain about one sixth of the whole of Australia (about the size of Germany, France, Italy combined) – but a sixth where rainfall is normally very low. But this season’s rains have been exceptionally high; the rivers are flowing – and the lake is filling.
When the lake does fill, it teems with life. Fish eggs that have lain buried in the salt for years hatch. Sea birds fly in nearly 1000 kilometres from the Southern Ocean. And it’s then that the enthusiasts come to play.
What’s this got to do with economics? Well economics is about scarcity and choice. Many of the choices we make are not simple buying and selling choices. Many clubs and other organisations thrive on the enthusiasm of their members. They’re not there to make money but certainly add to people’s ‘utility’. And enthusiasm, and hope, is what the members of the Lake Eyre Yacht Club have in abundance. Let’s hope they get lots of utility from sailing in the desert over the coming weeks.

Questions
- What attitude do the members of Lake Eyre Yacht Club have towards risk and uncertainty?
- How would you set about estimating the consumer surplus that members are likely to gain from attending the regatta and sailing on the lake?
- How price elastic would you expect the demand for and supply of services to be, such as ferry crossings and accommodation?
- What business opportunities are likely to be associated with sailing on the lake? Would it be ‘rational’ to set up such a business?
Whilst the internet and technological developments provide massive opportunities, they also create problems. For some time now, newspapers have seen declining sales, as more and more information becomes available online. Type something into Google or any other search engine and you will typically find thousands of relevant articles, even if the story has only just broken. As revenue from newspaper sales falls, revenue has to be made somewhere else to continue investment in ‘frontline journalism’. The question is: where will this come from?
The Financial Times and News Corp’s Wall Street Journal charge readers for online access and we can expect this to become more common from May, when the Times and the Sunday Times launch their new websites, where users will be charged for access. Subscription to these online news articles will be £1 per day or £2 for weekly access. Whilst the Executives of the Times admit that they will lose many online readers, they hope that the relatively low price, combined with a differentiated product will be enough of an incentive to keep readers reading.
Critics of this strategy argue that this a high risk strategy, as there is so much information available online. Whilst the BBC does plan to curtail the scope of its website, the Times and Sunday Times will still face competition from them, as well as the Guardian, the Independent, Reuters, etc., all of whom currently do not charge for online access. However, if you value journalism, then surely it’s right that a price should be charged to read it. Only time will tell how successful a strategy this is likely to be and whether we can expect other online news sites to follow their example.

Questions
- Why have newspaper sales declined?
- How might estimates of elasticity have been used to make the decision to charge to view online articles?
- ’If people value journalism, they should pay for it.’ What key economic concepts are being considered within that statement?
- Why is charging for access to the Times Online viewed as a high-risk strategy?
- What are the advantages and disadvantages of this strategy? To what extent do you think it is likely that other newspapers will soon follow suit?
- Which consumers do you think will be most affected by this strategy?
- In what ways might non-pay sites gain from theTimes’ charging policy?
- Would you continue to read articles from the Times linked from this site if you had to pay to access them? If so, why? If not, why not? (We want to know!!)
Are consumers ‘rational’ is the sense of trying to maximise consumer surplus? In some circumstances the answer is yes. When we go shopping we do generally try to get best value for money, where value is defined in terms of utility. With limited incomes, we don’t want to waste money. If we were offered two baskets of goods costing the same amount, we would generally choose basket A if its contents gave us more utility than basket B.
So why do we frequently buy things that are bad for us? Take the case of food. Why do we consume junk food if we know fresh produce is better for us? To answer this we need to look a little closer at the concept of utility and what motivates us when we consumer things. The following article does just that. It reports on writings of Michael Pollan. Pollan looks at our motivation when choosing what and how much to eat. For much of the time our choices are governed by our subconscious and by habit.
“Millions of humans, while believing they govern their actions with conscious intelligence, clean every morsel from their dinner plates, mainly because their parents told them to. And we do this even if we don’t particularly like the food on the plate and even if we know we should be eating less of it. Unthinkingly, we follow a habit we would condemn if we looked at it clearly.”
You mar what you eat and the politics of Michael Pollan National Post (Canada), Robert Fulford (18/1/10)
Questions
- What is meant by ‘rational behaviour’? Is it reasonable to assume that people are rational in most circumstances?
- Is eating junk food consistent with the attempt to maximise consumer surplus?
- How relevant is the principle of diminishing marginal utility in explaining the amount of junk food we eat?
- To what extent are the problems that Pollan identifies examples of (a) imperfect information; (b) irrationality?
- What does people’s eating behaviour reveal about their preferences for the present over the future and hence their personal discount rate?
- What are the policy implications of Pollan’s analysis for governments trying to get people to eat more healthily?
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?
