Obesity is on the rise, especially in children. With all the attendant health problems, concern is growing and various policies have been proposed to try to tackle the problem. One such policy is a sugar tax. This could be either a universal tax on sugar in food products or a tax just on soft drinks, many of which are very high in sugar – typically about seven teaspoons in a can or individual bottle.

Currently the issue is being considered by the UK’s Parliamentary Health Select Committee. Jamie Oliver, the TV chef and restaurateur, argued strongly before the committee in favour of a sugar tax on fizzy drinks. He has already imposed a levy on soft drinks with added sugar in his restaurants. He maintained that it was not just the higher price from a sugar tax that would deter consumption of such drinks, but it would send out an important message that too much sugar is bad for you.

Two days later, Dr Alison Tedstone appeared before the committee. She is chief nutritionist at Public Health England. PHE has been carrying out research into obesity and ways of tackling it. It has reviewed two types of evidence: experimental data on the effects of imposing higher prices on products with added sugar; and the effects of policies pursued in other countries. She stated to the committee that ‘universally all the evidence shows that the tax does decrease consumption’ and that ‘the higher the tax increase, the greater the effect’.

The government was not planning to publish the report at this stage, but under considerable pressure agreed to its publication.

The articles look at the prospects for a sugar tax, its likely effects if one were introduced and at the politics of the situation, which are likely to result in such a tax being rejected.

Questions

  1. What factors are driving the current high consumption of sugar?
  2. How is the concept of price elasticity of demand relevant to the effectiveness of imposing a sugar tax?
  3. What would determine the incidence of such a tax between food and drink manufacturers and consumers?
  4. Would such a tax be progressive, regressive or neutral? Explain.
  5. What other policies could be pursued to discourage the consumption of sugar? Discuss their likely effectiveness and compare them with a sugar tax.
  6. What externalities are involved in sugar consumption? How would you set about measuring them? Should a sugar tax be set at a rate that internalises the estimated externalities?
  7. Examine the objections to imposing a sugar tax.

The Gap has been a fixture of UK High Streets for many years and has had both ups and downs. In a highly competitive market, it faces fierce rivals from other high street retailers and also from an increasingly important online presence. Same-shop sales for Gap fell in July by 7% and the brand is now finding itself in a tricky position.

Although the Gap does sell products at a variety of prices, even sales growth in its most affordable line was not sufficient to offset declines elsewhere. It’s not just the UK where this decline is observed, with 175 Gap specialty shops in America being shut down over the next year. This will inevitably mean job losses. So why is Gap struggling so much, after being such a popular brand?

Its competitors are arguably offering a very similar product, but at a lower price. Consumers, being increasingly aware of prices and having many more options to make price comparisons, are perhaps using this information to make better choices. If they don’t believe that they are getting something extra from paying a slightly higher price at Gap, then they’d prefer to get the same thing elsewhere, from somewhere like Forever 21 or H&M. Some also suggest that the product itself is out of date and with the world of high fashion being such an important part of life for many people, an out-of-date product is bad news. That, together with consumers finding more and more things that they can spend their money on, beyond clothes has led to a tricky position for the Gap.

A key part of maintaining a presence on high streets has been sales and special offers – this has been a key element in keeping customers coming, but it is certainly not a long term strategy. Research analysts have been investigating some of the key aspects of the Gap and various comments have been made, including:

“Uniformity is no longer cool… The trick now is convincing your customer that they’re getting something unique.” (Simeon Siegel), Nomura Securities.

“Of top priority is delivering more consistent and compelling product collections.” Kari Shellhorn, Gap spokeswomen.

“Whether it’s colour or print or it’s pattern, the Gap brand hasn’t been kept up to date … Until they have their product right, I think we’ll continue to see them have promotions.” Dana Telsey, Telsey Advisory Group.

The future of Gap is certainly in the balance and with an increasingly competitive market when it comes to retail, an effective strategy to maintain and increase its market share will be essential.

Questions

  1. What sort of figure would you expect Gap’s clothes to have and why?
  2. Into which market structure would you place the retail industry? What does this tell us about how a company such as Gap can hope to make profits?
  3. If you were advising Gap, what strategies would you propose as a means of boosting revenue and cutting costs?
  4. The BBC News article states that the fortunes of Gap have been hurt by a strong US dollar. Why may this be the case?

For years, the UK consumer organisation, Which?, has exposed misleading supermarket pricing practices. These include bogus price reductions, ‘cheaper’ multi-buys, smaller pack sizes and confusing special offers. Claiming that these practices are still continuing, Which? has made a super-complaint (available to designated consumer bodies) to the competition regulator, the Competition and Markets Authority (CMA).

Commenting on this action, Which? executive director, Richard Lloyd said:

“Despite Which? repeatedly exposing misleading and confusing pricing tactics, and calling for voluntary change by the retailers, these dodgy offers remain on numerous supermarket shelves. Shoppers think they’re getting a bargain but in reality it’s impossible for any consumer to know if they’re genuinely getting a fair deal.

We’re saying enough is enough and using one of the most powerful legal weapons in our armoury to act on behalf of consumers by launching a super-complaint to the regulator. We want an end to misleading pricing tactics and for all retailers to use fair pricing that people can trust.”

The CMA will consider the issues raised under the super-complaint to establish whether any of them are significantly harming the interests of consumers. It will publish a response within 90 days from the receipt of the complaint on 21 April 2015. The possible outcomes include:

recommending the quality and accessibility of information for consumers is improved
encouraging businesses in the market to self-regulate
making recommendations to government to change the legislation or public policy
taking competition or consumer enforcement action
instigating a market investigation or market study
a clean bill of health

Some 40% of groceries are sold on promotion. Supermarkets are well aware that consumers love to get a bargain and use promotions to persuade consumers to buy things they might not otherwise have done.

What is more, consumer rationality is bounded by the information and time available. People are often in a hurry when shopping; prices change frequently; people are often buying numerous low-value items; and they don’t know what competitors are charging. People may thus accept an offer as genuine and not spend time investigating whether it is so. Supermarkets know this and use all sorts of tactics to try to persuade people that they are indeed getting a bargain.

The Budget takes place on 17th March 2015 and as always there is much speculation as to what it will and won’t include. One industry that is eagerly awaiting Osborne’s Budget is the North Sea oil and gas industry. Tax cuts and rises may well play a key role in the Budget, but this is one sector where a possibly large tax cut is expected.

The tax paid by this industry is very high compared to others, potentially reaching 80%. The tax rate was increased some years ago and it is now thought that it may come back down. One key factor is oil prices: with such huge decreases in the price of oil relative to when the tax on the industry was increased, the industry is now asking for these tax rises to be reversed. The industry has suggested that a 10% tax cut is a possibility and this would make a big difference for the industry.

Danny Alexander, the chief secretary to the Treasury, said:

“We’ve been very clear that the direction of travel for tax in the North Sea needs to be downwards … And that needs to be even stronger given the low oil price we see at the moment. We want people to have the confidence to invest for the long term future of the North Sea … And so George Osborne and I have been listening very carefully to what the industry has been saying …People will have to wait and see what we say on Wednesday [Budget day], but I hope very much that it will give the North Sea that confidence that we all want to see for one of Britain’s most important industries.”

We may also see further changes for this industry, such as allowances to encourage further investment, as costs of investment are extremely high and this has led to many years of under-investment. These changes are hoped to regenerate this industry. Any change in tax allowances or tax rates will have an impact on tax revenue and it is not necessarily the case that an increase in tax will lead to a rise in revenue or a fall in revenue. The relationship between tax rates and tax revenues can be very complex. The following articles consider this particular issue and what the Budget will do for this industry.

Many UK coal mines closed in the 1970s and 80s. Coal extraction was too expensive in the UK to compete with cheap imported coal and many consumers were switching away from coal to cleaner fuels. Today many shale oil producers in the USA are finding that extraction has become unprofitable with oil prices having fallen by some 50% since mid-2014 (see A crude indicator of the economy (Part 2) and The price of oil in 2015 and beyond). So is it a bad idea to invest in fossil fuel production? Could such assets become unusable – what is known as ‘stranded assets‘?

In a speech on 3 March 2015, Confronting the challenges of tomorrow’s world, delivered at an insurance conference, Paul Fisher, Deputy Governor of the Bank of England, warned that a switch to both renewable sources of energy and actions to save energy could hit investors in fossil fuel companies.

‘One live risk right now is of insurers investing in assets that could be left ‘stranded’ by policy changes which limit the use of fossil fuels. As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.

… As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.’

Much of the known reserves of fossil fuels could not be used if climate change targets are to be met. And investment in the search for new reserves would be of little value unless they were very cheap to extract. But will climate change targets be met? That is hard to predict and depends on international political agreements and implementation, combined with technological developments in fields such as clean-burn technologies, carbon capture and renewable energy. The scale of these developments is uncertain. As Paul Fisher said in his speech:

‘Tomorrow’s world inevitably brings change. Some changes can be forecast, or guessed by extrapolating from what we know today. But there are, inevitably, the unknown unknowns which will help shape the future. … As an ex-forecaster I can tell you confidently that the only thing we can be certain of is that there will be changes that no one will predict.’

The following articles look at the speech and at the financial risks of fossil fuel investment. The Guardian article also provides links to some useful resources.
