Tag: price elasticity of demand

Oil prices will remain below $60 per barrel for the foreseeable future. At least this is what is being assumed by most oil producing companies. In the more distant future, prices may rise as investment in fracking, tar sands and new wells dries up. In meantime, however, marginal costs are sufficiently low as to make it economically viable to continue extracting oil from most sources at current prices.

The low prices are partly the result of increases in supply from large-scale investment in new sources of oil over the past few years and increased output by OPEC. They are also partly the result of falling demand from China.

But are low prices all bad news for the oil industry? It depends on the sector of the industry. Extraction and exploration may be having a hard time; but downstream, the refining, petrochemicals, distribution and retail sectors are benefiting from the lower costs of crude oil. For the big integrated oil companies, such as BP, the overall effect may not be as detrimental as the profits from oil production suggest.

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.

Most of us will have milk in our fridges – it’s a basic product consumed by the majority of people on a daily basis and hence a common feature of most shopping trolleys. As we saw in the post Got milk?, the low price of milk has been causing problems for farmers. This has caused one Morrisons store to take a different approach.

In the increasingly globalised world, British dairy farmers are no longer competing against each other. The global market place means that they are now facing growing competition from abroad and in this global world, supply exceeds demand. Even in the EU, the member states in 2015 are exceeding the milk production levels from 2014. In many markets, we wouldn’t be so concerned about production (or supply) rising, as demand can keep pace. However, in the market for milk, it’s not a product that you consume (that much) more of as your income rises. So, as the world gets richer, demand for milk is not increasing at the same pace as supply – demand in China has collapsed. This means that prices are being forced down. Adding to this global market place, we saw the European Union remove its quotas on milk production, thus boosting supply and Russian bans on imports.

The farmers themselves are in a tricky situation. They are often the small players in the supply chain, with prices being forced down by customers, supermarkets and milk processors. AHDB Dairy, the trade body, says that the average price of milk has decreased to just 23.66p per litre. According to leading industry experts this is well below the costs of production, suggested to be closer to 30p per litre. If these figures are even close to being accurate, then clearly dairy farmers’ costs of production per litre are no longer covered by the price they receive. Every litre of milk produced represents a loss.

The price that supermarkets pay to farmers for milk does vary, with some such as Marks and Spencer and Tesco ensuring that they pay farmers a price above cost. However, Morrisons in Bradford has adopted a new strategy and brand. Their new milk brand ‘Morrisons Milk for Farmers’ has been launched at a 23p price rise for every four pint bottle. The catch: they will become the first UK retailer where the 23p price hike goes directly to farmers. This represents 10 pence per litre of milk going directly back to the farmers that produce it. This is a bold strategy, but data and surveys do suggest a willingness to pay more from customers, if it means that dairy farmers get a fairer deal. The protests we have seen across the country have certainly helped to generate interest and created awareness of the difficulties that many farmers are facing. Rob Harrison from the NFU said:

“We are pleased that Morrisons has acknowledged the desperate situation that many dairy farmers still find themselves in and recognise that retailers have a big role to play in, helping customers to support the UK dairy sector…

…Research from Mintel revealed over half of people who drink cows milk, would be prepared to pay more than £1 for a four-pint bottle of milk, as long as it is dairy farmers that benefit. This new initiative will enable them to do just that. The 10p a litre extra will go directly back into the dairy sector will make a difference on farm.”

The interesting thing will be to observe the impact on sales following this 23p price rise. We would normally expect customers to look for the cheaper substitutes, but evidence does suggest that British consumers are willing to pay the price premium if it means helping British farmers. A similar strategy adopted for British Cheddar Cheese proved fruitful and over the coming weeks, we will see if the average consumer is willing to pay directly the dairy farmers.

Questions

  1. Using demand and supply analysis, explain which factors have caused the price of milk to fall.
  2. When incomes rise, the demand for milk does not really change. What does this suggest about the income elasticity of demand for milk and the type of product that it is?
  3. If prices rise and sales also rise, does this suggest that British milk has an upward sloping demand curve?
  4. If we do see little effect on the demand for milk following Morrisons 23p price rise, what conclusion can we come to about the price elasticity of demand?
  5. Why do supermarkets and milk processors have the power to force down prices paid to dairy farmers?
  6. What type of market structure do you think dairy farmers compete in?
  7. If dairy farmers are unable to sell a litre of milk for a higher price than it costs to produce, is it a sensible strategy for them to remain in the market?

Most observers were once again left stunned by how much media companies are willing to pay to secure the rights to broadcast live games in the English Premier League (EPL). At the same time the method used to sell those rights is being investigated by Ofcom following complaints made by Virgin Media. Virgin Media actually requested that the auction was halted until the investigation was completed.

Between them, BSkyB and BT Sport have paid £5.136bn to purchase the rights to broadcast live matches in the EPL over a three-year period beginning in the 2016–17 season. This is a 71% increase in the price paid for the previous three-year deal which runs from 2013 to 2016 and cost £3.018bn. However, the headline figure hides some big differences between the amounts paid by the two companies.

How exactly are the rights sold? The broadcast rights for the 168 live matches are split up into seven different packages labelled A through to G and are placed in seven different auctions. The type of auction used by the EPL is a sealed bid auction. Interested companies are invited to make an offer for any of the packages. However, when they make a bid they do not know (a) if other firms have also made a bid and (b) the size of any other bids. Another constraint is that one firm is not allowed to win more than five of the auctions. When the auction finishes the EPL only releases information about the winning offers. It never provides information about any of the failed bids.

Some of the packages are worth more than others to the broadcasters. The first five packages (A–E) each contain the rights for 28 games per season, while the other two packages (F and G) contain the rights for 14 matches. In some of the packages all of the games kick off at the same time and on the same day. For example all 28 games in package ‘A’ kick off at 12.30pm on a Saturday. Others contain more of a mixture. Some of the games in Package E take place on a Monday evening. while others take place on a Friday evening. Given the potential advertising revenue and number of viewers, the most valuable package is D, which has 28 games that kick off at 4.00pm on a Sunday.

Another factor that influences the value of a package is the number of ‘first picks’. In any given week, more than one broadcaster might want to screen the same match. To overcome this problem, each package is allocated a number of first, second, third, fourth and fifth ‘picks’. For example, package D comes with 18 first and 10 fourth round picks. This means that whichever company wins this package will get first choice on the games they want to broadcast on 18 occasions a year. Package C contains no ‘first picks’ but offers 15 second, 4 fourth and 7 fifth round picks. There is also a maximum and a minimum limit on the number of times games including a specific team can be broadcast.

BSkyB won the auctions for packages A, C, D, E and G for a price of £4.17bn. This means that it will be paying £1.396bn to broadcast 126 live games per season. This is an average payment of £11,031,700 per game. In the previous deal it paid £760million for the rights to broadcast 116 live games per season. This is an average payment of £6,551,724 per game. The new deal represents a cost increase of 68% per game. However, the number of first picks BskyB has secured in the new deal increases from 20 to 26.

BTSport won the auctions for packages B and F for a price of £960m. This means that it will be paying £320m for the rights to broadcast 42 live games per season. This is an average payment of £7,619,048 per game. In the previous deal it paid £246 million per year for the rights to broadcast 38 live games per season. This is an average payment of £6,473,684 per game. The new deal represents an increase in costs of 17.7% per game for BT Sport – a much lower figure than for BSkyB.

BSkyB has stated that it will cover the increase in the price it has paid for the rights with efficiency savings. However, many observers believe that it will ultimately result in significant increases in the subscription rates for SkySports. The impact of the deal on BskyB’s profit may well depend on the willingness of its customers to pay higher prices. What is the price elasticity of demand for SkySports at the current subscription rates they are charging?

There is still some uncertainty about the deal following Ofcom’s decision to investigate the legitimacy of the method used by the EPL to auction the rights. Virgin Media made a formal complaint in September 2014 about the collective selling of the live broadcast rights and argued that it was in breach of competition law. The investigation by Ofcom will make a judgment about whether the joint selling of the rights by the EPL is a contravention of Chapter I of the Competition Act 1998 and/or Article 101(1) of the Treaty on the Functioning of the European Union. An initial announcement will be made in March.

Over the past three months oil prices have been falling. From the beginning of September to the end of November Brent Crude has fallen by 30.8%: from $101.2 to a four-year low of $70.0 per barrel (see chart below: click here for a PowerPoint). The fall in price has been the result of changes in demand and supply.

As the eurozone, Japan, South America and other parts of the world have struggled to recover, so the demand for oil has been depressed. But supply has continued to expand as the USA and Canada have increased shale oil production through fracking. As far as OPEC is concerned, rather than cutting production, it decided at a meeting on 27 November to maintain the current target of 30 million barrels a day.

The videos and articles linked below look at these demand and supply factors and what is likely to happen to oil prices over the coming months.

They also look at the winners and losers. Although falling prices are likely in general to benefit oil importing countries and harm oil exporting ones, it is not as simple as that. The lower prices could help boost recovery and that could help to halt the oil price fall and be of benefit to the oil exporting countries. But if prices stay low for long enough, this could lower inflation and even cause deflation (in the sense of falling prices) in many countries. This, in turn, could dampen demand (see the blog post, Deflation danger). This is a particular problem in Japan and the eurozone. Major oil importing developing countries, such as China and India, however, should see a boost to growth from the lower oil prices.

Some oil exporting countries will be harder hit than others. Russia, in particular, has been badly affected, especially as it is also suffering from the economic sanctions imposed by Western governments in response to the situation in Ukraine. The rouble has fallen by some 32% this year against the US dollar and nearly 23% in the past three months alone.

Then there are the environmental effects. Cheaper oil puts less pressure on companies and governments to invest in renewable sources of energy. And then there are the direct effects on the environment of fracking itself – something increasingly being debated in the UK as well as in the USA and Canada.
