The model of demand and supply is one of the first diagrams that any student of Economics will see and it’s a very important model. We can apply it to a multitude of markets and understand how market prices for products and services are determined. One such market is that of wine, where a recent report suggests that wine is in short supply. Bad news for everyone!
The price of wine is set by the interact of demand and supply. As with any market, numerous factors will affect how much wine is demanded at any price. Since 1996, global consumption of wine has been on the increase: for many, wine is a luxury good and thus as income rises, so does consumption. With the emergence of markets, such as China and subsequent income growth, consumption has risen. Furthermore, tastes have changed such that wine is becoming an increasingly desirable drink. So, this has all led to the demand curve shifting to the right.
However, at the same time, the supply of wine has been falling, largely the result of ‘ongoing vine pull and poor weather’ across Europe. European production has fallen by around 10% over the past year and although production in other countries has been rising, overall production is still not sufficient to match the growth in demand.
So, what’s the result of this high growth in demand combined with the decline in supply? A shortage of wine. A report by analysts at Morgan Stanley suggests that the global wine shortage was some 300m cases in 2012. But, more importantly what is the effect of this shortage? When demand for a product exceeds the supply, the market mechanism will push up the price. As stocks of wine continue to be depleted and consumption of wine keeps rising, the only outcome is a rise in the price of a bottle and a crate of wine.
Concerns are also being raised about the future of prices of some of our other favourite luxury products, such as chocolate, goats cheese and olives. In each case, it’s all about demand and supply and how these curves interact with each other. The following articles consider the prices of some of these products.

‘Farm-gate’ milk prices (the price paid to farmers) have been rising in the UK. In July they reached a record high of 31.4p per litre (ppl). This was 5.1ppl higher than in July 2012. There were further price rises this month (October). Sainsbury’s increased the price it pays farmers by nearly 2ppl to 34.15ppl and Arla Foods by 1.5ppl to 33.13ppl. Muller Wiseman is set to raise the price it pays to 32.5p per litre.
And yet many farmers are struggling to make a profit from milk production, claiming that their costs have risen faster than the prices they receive. Feed costs, for example, have risen by 2.12ppl. On average, farmers would need over 38p per litre just to cover their average variable costs. What is more, exceptional weather has reduced yields per cow by some 7%.
Meanwhile, in the USA, supply has risen by some 1.3% compared with a year ago. But despite this, the prices of dairy products are rising, thanks to strong demand. Cheese and butter prices, in particular, are rising rapidly, partly because of high demand from overseas. Demand for imported dairy products is particularly high in China, where supply has fallen by some 6% in the past couple of months.
The problem for dairy farmers in the UK is partly one of the power balance in the industry. Farmers have little or no market power. Supermarkets, however, have considerable market power. As large oligopsonistic buyers, they can put downward pressure on the prices paid to their suppliers. These are mainly large processing firms, such as Robert Wiseman Dairies, Arla Foods and Dairy Crest. They, in turn, can use their market power to keep down the price they pay to farmers.

No matter the product or service, price is always a key factor and never more so than in tough economic times. In most cases, prices are allowed to be determined by the forces of demand and supply, which gives the equilibrium price. However, in some cases, the government may choose to intervene with a price control, for example rent controls and the national minimum wage. Another market where there is also regulation is the airline industry and the Civil Aviation Authority have recently been criticized by Heathrow Airport for its price control plan.
Whenever we go on holiday, the price we pay for an airline ticket will depend in part on the airport we are taking off from and landing at, as they will charge the airline for landing fees, security, terminals etc. 
Heathrow airport had proposed that annual rises to its tariffs charged to airlines would increase by 4.6% above RPI inflation. However, this plan has been rejected by the CAA, which has said that the annual tariff rise between 2014 and 2018 should not be above the RPI. Though Heathrow are criticizing the CAA about this restriction, it is an improvement from the initial proposal which would have capped price rises at the RPI minus 1.3%.
Controversy has naturally been created, with the CAA arguing that such price controls are needed to keep prices down and thus benefit consumers and retain the competitiveness of Heathrow airport. But, in contrast, Heathrow has argued that such a cap will put its competitive position under pressure and will risk future investment in the UK. But this isn’t the only criticism of the CAA. Airlines aren’t happy with the ruling either, arguing that the CAA has bowed to the pressure of Heathrow. The contrasting positions of the CAA, Heathrow and airlines are evident in the following quotes, firstly from the Chairwoman of the CAA:
The proposals will put an end to over a decade of prices rising faster than inflation at Heathrow. Tackling the upward drift in Heathrow’s prices is essential to safeguard its globally competitive position. The challenge for Heathrow is to maintain high levels of customer service while reducing costs. We are confident this is possible and that our proposals create a positive climate for further capital investment, in the passenger interest.
Secondly, from Heathrow’s Chief Executive:
This proposal is the toughest Heathrow has ever faced. The CAA’s settlement could have serious and far-reaching consequences for passengers and airlines at Heathrow … We want to continue to improve Heathrow for passengers. Instead, the CAA’s proposals risk not only Heathrow’s competitive position but the attractiveness of the UK as a centre for international investment. We will now carefully consider our investment plans before responding fully to the CAA.
And finally from the IAG Chief Executive, who said:
[The CAA] neglected its new primary statutory duty to further the interests of passengers by endorsing a settlement that allows the UK’s monopoly hub to ignore its inefficiencies and over-reward investors by imposing excessive charges … It is a bad day for customers who have been let down by the CAA.
Any price rise from the airports will be passed on to airlines and these in turn will translate into higher prices for customers. However, is there any truth to Heathrow’s claims that investment will be adversely impacted? As costs rise, profit margins and profit will fall, unless the revenue generated can increase. Price controls restrict the amount that prices can rise and thus unless demand increases by a significant margin, profits will decline. With lower profits, there will be less money for investment and arguably the service that customers face will also decline. However, the CAA suggests that Heathrow will be able to cut its costs and thus protect investment into the future, while retaining its competitive position globally by charging lower prices to airlines. This is unlikely to be the end of the journey, but for the moment, the CAA appears to have put its foot down. The following articles consider the battleground between the CAA and Heathrow.

- If Heathrow is unable to cut costs, what is the likely effect? Using a diagram illustrate the impact on profitability if costs (a) can be reduced and (b) cannot be reduced.
- Why are the CAA being criticised by airlines and airports?
- How will customers be affected by Heathrow’s planned price rises and the CAA’s proposal?
- ‘Regulation in the airlines industry is essential to retain competitiveness.’ Evaluate the validity of this statement.
Did the benefits of the London Olympics outweigh the costs? The government’s UK Trade and Industry (part of the Department of Business, Innovation & Skills) has just published a report, London 2012, Delivering the economic legacy, which itemises the economic benefits of the games one year on. It claims that benefits to date are some £9.9 billion.
This compares with costs, estimated to be somewhere between £8.9 billion and £9.3 billion, although this figure does not include certain other costs, such as maintenance of the stadium. Nevertheless, according to the figures, even after just a year, it would seem that the Games had ‘made a profit’ – just.
The £9.9 billion of benefits consist of £5.9 billion of additional sales, £2.5 billion of additional inward investment and £1.5 billion of Olympic-related high value opportunities won overseas. 
Most of these can be seen as monetary external benefits: in other words, monetary benefits arising from spin-offs from the Games. The ‘internal’ monetary benefits would be largely the revenues from the ticket sales.
In a separate report for the Department of Culture, Media & Sport, Report 5: Post-Games Evaluation, it has been estimated that the total net benefits (net gross value added (GVA)) from 2004 to 2020 will be between £28 billion and £41 billion.
But benefits are not confined just to internal and external monetary benefits: there are also other externalities that are non-monetary. The Culture, Media & Sport report identified a number of these non-monetary externalities. The Summary Report itemises them. They include:
• The health and social benefits of more people participating in sport
• Inspiring a generation of children and young people
• A catalyst for improved elite sporting performance in the UK
• Setting new standards for sustainability
• Improved attitudes to disability and new opportunities for disabled people to participate in society
• Greater social cohesion as communities across the UK engaged with the Games
• Increased enthusiasm for volunteering
• Accelerated physical transformation of East London
• Beneficial socio-economic change in East London
• Important lessons learned for the co-ordination and delivery of other large-scale public and public/private projects
But with any cost–benefit analysis there are important caveats in interpreting the figures. First there may be monetary and non-monetary external costs. For example, will all the effects on social attitudes be positive? Might greater competitiveness in sport generate less tolerance towards non sporty people? Might people expect disabled people to do more than they are able (see)? Second, the costs generally precede the benefits. This then raises the question of what is the appropriate discount rate to reduce future benefits to a present value.
Perhaps the most serious question is that of the quantification of benefits. It is important that only benefits that can be attributed to the Games are counted and not benefits that would have occurred anyway, even if connected to the Games. For example, it is claimed in the UK Trade & Industry report that much of the Olympic park and stadium for the Winter Olympics in Russia was “designed and built by British businesses”. But was this the direct result of the London Olympics, or would this have happened anyway?
Another example is that any inward investment by any company that attended the London Olympics is counted in the £2.5 billion of additional inward investment (part of the £9.9 billion). As the London Evening Standard article below states:
In London, it credited the Games with helping seal the deal for the £1.2 billion investment in the Royal Albert Docks by Chinese developer ABP, the £1 billion investment in Croydon by Australian shopping centre developer Westfield with UK firm Hammerson and the £700 million investment in Battersea Nine Elms by Dalian Wander Group.
It is highly likely that some or all of these would have gone ahead anyway.
Then there are the £5.9 billion of additional sales. These are by companies which engaged with the Olympics. But again, many of these sales could have taken place anyway, or may have displaced other sales.
Many cost–benefit analyses (or simply ‘benefit analyses’) concern projects where there are strong vested interests in demonstrating that a project should or should not go ahead or, in this case, have gone ahead. The more powerful the vested interests, the less likely it is that the analysis can be seen as objective.

Technology and the Internet have both good and bad sides, whether it’s for businesses or consumers. Many opportunities have been created, such as access to global markets, cheaper and easier transport and communication and better sources of supply. But with this opportunity comes threats, especially for businesses. We’ve seen the emergence of new online-based companies and in some cases these have contributed to the demise of other firms. In this News Item we look at the impact on the newspaper industry.
Media is one industry that has been significantly affected by technological developments. Newspaper readership has been in decline for many years and this is even the case for the most widely read UK paper – The Daily Telegraph. However, according to Seamus Dooley, Irish secretary of the National Union of Journalists, it’s not the end of the industry:
It is an industry in crisis, but I don’t accept it is an industry in terminal decline.
More and more information has become freely available online and just as we would expect in any other sector, the newspaper industry has had to respond. To keep their readers, newspapers across the world provide thousands of articles on all topics on their websites. But if news can be accessed freely, why bother purchasing a newspaper? This is the problem facing the Daily Telegraph, the Independent, the Daily Mail etc – the number of newspapers sold has declined and thus so have revenues and profits.
One option is to charge consumers for reading the news by introducing a subscription to the online articles. The Financial Times already charges a fee to view articles online beyond a certain number and The Telegraph is soon to follow suit. Back in 2010, The Times and Sunday Times launched their new websites, which charged readers for viewing articles. The model being adopted by The Telegraph is a little different, as a certain number of articles can be viewed for free before a price must be paid. International readers are already charged to view online material, but these new charges will apply to UK readers. With so much competition facing newspapers, the number of readers for The Telegraph will undoubtedly decline, but with newspaper readership falling, revenues must come from somewhere. Tony Gallagher has said:
We want to develop a closer rapport with our digital audience in the UK, and we intend to unveil a number of compelling digital products for our loyal subscribers in the months ahead.
Differentiating the product is going to be essential for any newspaper that begins charging, as with so much information available online for free, they have to ensure they keep their readers. Establishing loyalty will be crucial. The following articles consider this change.
