A simple model in economics is that of demand and supply. Through the price mechanism, signals are sent between consumers and producers and this interaction results in an equilibrium market price and quantity. However, what happens when the market for a good or service is in disequilibrium?

When a market is in equilibrium, demand equals supply. However, as we discussed in a previous blog concerning baby milk in China (see Milking the economy), markets are not always in equilibrium. If demand exceeds supply, a shortage will emerge and to eliminate this, the price must rise. If, on the other hand, supply exceeds demand, there will be an excess supply and thus the price must fall to restore equilibrium.

The market in question here is toilet paper in Venezuela! A severe shortage of this product has emerged in recent months, with shops running out of supplies. In a bid to relieve this shortage, the country’s Minister of Commerce has received approval for a $79 million credit, which can be used to import this basic product in short supply. Fifty million rolls will be imported to help fill the shortage that has emerged. The shortage is not just a problem for toilet paper, but also across a range of basic consumer goods. The article from Reuters comments that:

The government says the toilet paper shortages, like others, are the results of panicked buying and unscrupulous merchants hoarding the goods to artificially inflate prices.

Opposition critics say the problem is caused by the currency controls, created a decade ago by late socialist leader Hugo Chavez, and years of nationalizations that weakened private industry and left businesses unwilling to invest.

With shortages across a variety of products, the President has begun to work closely with business leaders to address this situation. The following articles consider this basic market, the intervention and consequences.

The market for any good or service is affected by countless factors. On the demand-side, things such as incomes, relative prices, expectations of price changes and tastes determine the shape and position of the demand curve. For the supply curve, it’s factors including costs of production, the profitability of alternative goods and in some cases, the weather or natural disasters. It is this last factor, which has presented Weetabix with problems.

An established breakfast cereal and brand, Weetabix is well-known for producing a range of high quality products. However, production of some of its most popular products has been stopped, as the quality of the British wheat used to make the various cereals was called into question. Last year, we had little summer to speak of and this led to the ‘worst harvest we have seen in decades’, so much so that the quality of the wheat was not sufficient to be used in making the breakfast cereal. This has caused production to cease on certain products and shortages have already begun to emerge, with some shops completely selling out and facing no prospect of being re-stocked.

Weetabix is now owned by a Chinese state-owned company, but still prides itself on using locally sourced wheat. However, with the weather affecting the harvest, wheat from abroad has had to be used, aiming to reduce the gap between demand and supply. The UK is typically an exporter of wheat, but with the poor harvest has come a drop in the amount of wheat produced and thus exported by some 2m tonnes – this is back to a similar level as was seen in the 1980s. A spokesman for Weetabix said:

Normally they’re proud to claim Weetabix is not just British wheat but from within 50 miles of Burton Latimer … They have had to source a bit from outside the UK, but Weetabix is still proud to say it sources its wheat within the UK … weather permitting.

Supply will be increased once wheat from abroad is used, but it is expected that this will take a couple of weeks. In the meantime, if you’re a consumer of the traditional Weetabix, you don’t need to worry, as it’s the less-known cereals that have been affected. The following articles consider this external factor and how it affects the supply of a product.

When you hear about China, it’s often regarding their huge population, their strong growth or their dominance in exports. But, when it comes to baby milk, China is certainly an importer – and a big one at that. For many new parents, getting the ‘real thing’ when it comes to baby formula is absolutely essential.

Chinese baby formula is feared by many new parents, due to the potential for it to contain hormones and dangerous chemicals. This has led them to go to great lengths to ensure they have sufficient supplies of imported baby formula, often only trusting it if it has been hand carried from overseas. However, such is the demand for this safe version of baby milk that the global response has been to place restrictions on it. Essentially, we are seeing a system of rationing emerging.

Hong Kong was the first government to limit the amount bought to two cans of formula per day, with the potential for a fine of over $64,000 and up to two years in prison for those who do not abide by the rules. The UK has now also responded with restrictions on the quantity that can be purchased and other countries may follow suit if the excess demand continues.

According to Sainsburys:

As a short-term measure, retailers including Sainsbury’s are limiting the amount of baby milk powder that people can buy. In this way we aim to ensure a constant supply for our customers and we therefore hope they won’t be inconvenienced.

The Chinese government has reacted to this and is aiming to restore confidence in the food industry, but as yet there has been little positive effect and until there are 100% guarantees of food safety the surge in demand for baby formula from abroad is likely to continue.

This policy of rationing is clearly not only going to affect Chinese parents looking to import baby formula, but is already having an impact on domestic residents. Parents living in the UK are feeling the rationing effects and are also being restricted in terms of how many cans of formula they can buy per day. For many families this isn’t a problem, but for those with multiple children and for whom a trip to the supermarket is not a simple task, the restrictions on baby milk purchases is likely to become a problem.

In the blog No accounting for trade, the rise in the UK’s balance of trade deficit was discussed. Many factors have contributed to this weakening position and no one market is to blame. But, by analysing one product and thinking about the factors that have caused its export volumes to decline, we can begin to create a picture not just of the UK economy (or more particularly Scotland!), but of the wider global economy.

Scotch whisky may not have been the drink of choice for many British adults, but look outside Great Britain and the volume consumed is quite staggering. For example, French consumers drink more Scotch whisky in one month than they drink cognac in one year. The volume of Scotch whisky exported from our shores was £4.23 billion for 2011, accounting for 90% of all sales and making its way into 200 markets. However, one problem with this product is that it is highly susceptible to the business cycle. Add to this the time required to produce the perfect Scotch (in particular the fact that it must be left to mature) and we have a market where forecasting is a nightmare.

Producers typically look to forecast demand some 10 years ahead and so getting it right is not always easy, especially when the global economy declines following a financial crisis! So what has been the impact on exports of this luxurious drink? In the past few years, it has been as key growth market for UK exports rising by 190% in value over the past decade. But in 2012 the volume of Scotch whisky exports fell by 5% to 1.19 billion bottles. What explains the decline in sales?

The biggest importer of Scotch whisky is France and its volumes were down by 25%. Part of this decline is undoubtedly the economic situation. When incomes decline, demand for normal goods also falls. Many would suggest Scotch whisky is a luxury and thus we would expect to see a relatively large decline following any given fall in income. However, another factor adding to this decline in 2012 is the increased whisky tax imposed by the French government. Rising by 15% in 2012, commentators suggest that this caused imports of Scotch whisky to rise in 2011 to avoid this tax, thus imports in 2012 took a dive. Spain is another key export market and its economic troubles are clearly a crucial factor in explaining their 20% drop in volume of Scotch whisky imported.

But, it’s not all bad news: sales to Western Europe may be down, but Eastern Europe and other growth countries/continents, such as the BRICs and Africa have developed a taste for this iconic product. Latvia and Estonia’s value of Scotch whisky imports were up by 48% and 28% respectively, as Russian demand rises and China, still growing, is another key market. Gavin Hewitt, chief executive of the Scotch Whisky Association said:

A combination of successful trade negotations, excellent marketing by producers, growing demand from mature markets, particularly the USA, and the growing middle class in emerging economies helped exports hit a record £4.3bn last year.

Furthermore, while the volume of exports worldwide did fall, the value of these exports rose to £4.27 billion, a growth of 1%. This suggests that although we are exporting fewer bottles, the bottles that we are exporting are more expensive ones. Clearly some people have not felt the impact of the recession. For Scotland and the wider UK, these declining figures are concerning, but given the cyclical nature of the demand, as the world economy slowly begins to recover, sales are likely to follow suit. Gavin Hewitt continued his comments above, saying:

We are contributing massively to the Government’s wish for an export-led recovery. There is confidence in the future of the industry, illustrated by the £2bn capital investment that Scotch whisky producers have committed over the next three to four years.

House prices have long been an obsession with the UK media and much of the public; when they rise, homeowners feel rich, when they fall, consumer confidence dives. Following the financial crisis and subsequent recession, there has been a great deal of attention focused on the overall health of the housing market.

But the UK faces a particular problem of a sharp and growing divide in regional house prices. First time buyers in London face having to find high deposits and even then, many are unable to access mortgages. Meanwhile those in the regions can access more affordable housing, but may be reluctant to enter the market when prices are stagnant. What are the implications of this divide for the housing market and for the broader economy?

The housing market demonstrates characteristics which are typical of those for goods that are both consumable and involve capital growth; when prices rise housing is seen as a good ‘investment’ and demand increases, this in turn leads to higher prices. Conversely when values drop, demand falls and the market slumps. Markets like this are described as being prone to price bubbles.

Looking at UK house prices as a whole can, however, mask large variations across the economy; variations which can cause problems for jobseekers, for employers and for the government. Recently one of the UK’s largest mortgage lenders predicted continuing regional variance in house prices. Halifax’s figures looked at the price of housing across a number of UK towns and showed that changes seen during 2012 ranged from a 14.8 per cent rise to an 18.4 per cent fall. The biggest rise seen during the year was in Southend on Sea, in Essex, while the greatest fall was in Craigavon, in Northern Ireland. Of the ten towns with the biggest rises, eight were found in London or the south east, with Durham being the only northern town showing growth. Of the ten towns that the Halifax identified with the biggest falls, four are in Scotland, three are in the north west, one is in the north of England and one is in Northern Ireland.

Martin Ellis, housing economist at the Halifax, said:

We expect continuing broad stability in house prices nationally in 2013. The generalised north/south divide in house price performance seen during 2012 is likely to continue next year. House prices are expected to be strongest in London and the south east as this part of the country performs best in economic terms.

These disparities present a particular problem in a recession. While London and the south east show signs of economic growth, with relatively low unemployment and high levels of inward investment, many regions outside London see house prices falling further as unemployment grows. There are some exceptions – the arrival of the BBC in Salford has resulted in a sharp increase in prices there – but, in general, confidence is low outside the south east.

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.

Adverts are increasingly diverse, ranging from families using various products and promoting their qualities, to a gorilla drumming, a horse dancing and a monkey drinking tea! But, how important is advertising to a product’s brand. Does it have a positive effect on sales and profitability?

The key role of advertising is to sell more products and many firms spend a huge amount on advertising campaigns. Indeed, over £16bn was spent on advertising in 2012. Given that the economy is still vulnerable and many firms have seen their sales and profits decline, this is a huge amount. Procter & Gamble spent over £200 million, British Sky Broadcasting spent £145 million and Tesco spent £114 million in 2011.

Advertising increases consumer awareness of the product and its features, but also actively aims to persuade people to purchase the product. By differentiating the product through adverts a company aims to shift the demand curve to the right and also make it more inelastic, by persuading customers that there are no (or few) close substitutes.

Since the start of the economic downturn in 2008, advertising expenditure has fallen, as companies have seen a decline in their budgets. From a high of £18.61 billion in 2004, the Advertising Association found that it fell to £14.20 billion in 2009 at constant 2008 prices. In the last few years, advertising expenditure has remained at around £14.5 billion. But, is cutting back on advertising a sensible strategy during a recession? Of course budgets are tight for both firms and consumers, but many suggest that media-savvy firms would actually benefit from maintaining their advertising. By doing so firms could take advantage of weaker competitors by increasing their market share and establishing their brand image in the long run.

It’s also important to consider another link between economic growth and advertising. Research suggests that advertising can be an important factor for economic growth. A three-year study undertaken by the Advertising Association and Deloitte, commencing in January 2013 suggests that for every £1 spent on advertising in the UK, £6 is generated for the wider economy. Based on these predictions, the estimated £16bn that was spent on ad campaigns in 2011 added over £100 billion to the UK’s GDP.

So, perhaps encouraging more advertising is the answer to the UK’s economic dilemma. This is certainly the opinion of Matt Barwell, the consumer marketing and innovation director of Diageo Western Europe, who said:

People fundamentally believe in advertising but a lot of the conversation focuses on negative elements. People rarely get the opportunity to talk about the positive role advertising plays in terms of wealth creation, exports and the social benefits that it provides. These are all things that many of us take for granted.

If private firms can therefore be encouraged to boost their marketing campaigns, jobs may be created, demand for products will rise and with the help of the multiplier, the economy may strengthen. Advertising has both pros and cons and opinions differ on what makes a good advert. But, whatever your opinion of the role of advertising, it is certainly an important aspect of any economy. The following articles take a view of advertising.

Investment is crucial in all sectors of the economy. With growing demand for travel abroad, airports across the world have begun implementing investment strategies to increase capacity. Airport bosses at Heathrow are currently considering a 5 year investment plan that is expected to cost £3 billion.

Although investment is certainly needed and passengers will benefit in the long run, the cost of this investment will have to be met by someone. If these plans are approved by the airport bosses, it is likely that ticket prices will be pushed upwards to pay for it. Any increase in charges will have to receive approval by the Civil Aviation Authority (CAA). The plan at the moment would see ticket prices, via landing charges, increase by £19.33 per passenger before a further rise to £27.30. The impact on customers has already been raised as a key concern.

If the investment plans proceed, Heathrow expects to see its passenger numbers increase by 2.6m over the next 5 years, despite the proposed price hikes. This would naturally increase revenue and this money would provide at least some of the funds to repay the cost of the investment.

The price rises have been described as ‘incredibly steep’ and there are concerns that they will penalize customers. Airlines, such as Virgin Atlantic have recognized the need for more investment, but are more focused on finding ways to provide it without the price rises.

However, Colin Matthews, the Heathrow Chief said:

Heathrow faces stiff competition from other European hubs and we must continue to improve the service we offer passengers and airlines.

Passengers have already seen prices rise and Heathrow’s cost base has been described by British Airways as ‘inefficient’. Despite the fact that the decision by the CAA is not expected until January 2014, speculation will undoubtedly continue until any decision is reach. The following articles consider this case.

The technology sector is highly complex and is led by Apple. However, as the tablet market is continuing to grow, it is becoming increasingly competitive with other firms such as Samsung gaining market share. Although both firms sell many products, it is the growing tablet market which is one of the keys to their continued growth.

Tablet PCs have seen a growth in the final quarter of 2012 to a high of 52.5 million units, according to IDC. Although Apple, leading the market, has seen a growth in its sales, its market share has declined to 43.6%. Over the same period, Samsung has increased its market share from 7.3% to 15.1%. While it is still a huge margin behind Apple in the tablet PC market, Samsung’s increase in sales from 2.2 million to 7.9 million is impressive and if such a trend were to continue, it would certainly cause Apple to take note.

It’s not just these two firms trying to take advantage of this growing industry. Microsoft has recently launched a new tablet PC and although its reception was less than spectacular, it is expected that Microsoft will become a key competitor in the long run. There are many factors driving the growth in this market and the war over market share is surely only just beginning. The chart shows the 75.3% growth in sales in just one year. (Click here for a PowerPoint of the chart.)

A Research Director at IDC said:

We expected a very strong fourth quarter, and the market didn’t disappoint…New product launches from the category’s top vendors, as well as new entrant Microsoft, led to a surge in consumer interest and very robust shipments totals during the holiday season’

Apple has been so dominant in this sector that other companies until recently have had little success in gaining market share. However, with companies such as Samsung and ASUS now making in-roads, competition is likely to become fierce. There are already concerns that Apple’s best days are behind it and its share price reflects this. People are now less willing to pay a premium price for an Apple product, as the innovations of its competitors have now caught up with those of the leading brand name.

It’s a relatively common dish to see on a menu at a restaurant: mackerel. This particular fish has been promoted as a healthy and sustainable dish, but now its sustainability is coming into question and the Marine Conservation Society has taken it off its ‘fish to eat’ list. My brother Hugh is a marine biologist and often comments on which fish we should be avoiding due to sustainability issues (especially given how much I like fish!) So, how is this an economics issue?

There a couple of key things to pick out here. Firstly, with the conservationists’ warning of this issue of unsustainability, they have been asking consumers to reduce the amount of mackerel they buy. This will naturally have an impact on fisherman. If consumers do listen to the conservationists and hence reduce their demand for mackerel, we could see a fall in the price of this fish and a reduction in the fishermen’s turnover. It could be that we see a switch in consumption to other more sustainable fish, especially if we see some form of intervention.

Another area concerning economics is the idea of over-fishing. For years, there have been disputes over who has the rights to these fish stocks. In the past, the Faroe Isles and Iceland have increased their quotas significantly, as mackerel appear to have migrated to their shores, contributing to this question of sustainability. Iceland and the Faroe Isles have ‘unilaterally agreed their quotas … as they are not governed by the common fisheries policy’.

The question is: when fisherman catch one additional mackerel, what are they considering? Do they think about the private benefit to them (or their company) or do they consider the external cost imposed on others? Whenever one fish is taken from the sea, there is one less fish available for other fishermen.

This leads to over-consumption of fish and contributes towards the well-documented depletion of fish stocks and ‘The Tragedy of the Commons’, if account is not taken of the external cost imposed on other fishermen.

The total catch is now far in excess of what has been scientifically recommended and previously agreed upon by all participating countries. Negotiations to introduce new catch allowances have so far failed to reach agreement.

There are hopes that an international policy on quotas can be agreed to ensure mackerel levels return to or remain at a sustainable level. However, at present no progress has been made. Until some form of an agreement is reached, fishermen around Iceland and the Faroe Isles will continue to battle against the conservationists. The following articles consider this fishy topic.
