Oligopoly is the most complex market structure, characterised by a few large firms which dominate the industry. Typically there are high barriers to entry and prices can be very sticky. However, perhaps the most important characteristic is interdependence. With this feature of the market, oligopolies, despite being dominated by a few big firms, can be the most competitive market structure.
There are many examples of oligopolies and one of the best is the supermarket industry. Dominated by the likes of Tesco, Morrisons and Asda, competition in terms of branding, product development and quality is constant, but so is price competition. 
During the recession, you could hardly watch a TV programme that included advert breaks without seeing one of the big four advertising their low prices.
However, in the past few years, the supermarket industry has seen competition grow even further and the big four are now facing competition from low-cost retailers, including Aldi and Lidl. This has led to falling sales and profits for the likes of Tesco and Morrisons.
Tesco, Morrisons, Sainsbury’s and Asda have all felt the emergence of discount retailers and have seen their customer numbers fall. All have reacted with rounds of price cuts and new deals, and this price war looks set to continue. Morrisons have just announced a 14% average price cut on 135 products to match earlier changes in pricing strategies by the other main competitors. As I’m writing this during the Algeria v. South Korea match, I have just seen an advert from Sainsbury’s, promoting their milk chocolate digestive biscuits, priced at £1. The advert explicitly states that they are ‘less than Morrisons’, where the price is £1.50. This was soon followed by another from Sainsbury’s saying that 
the Cif bathroom spray is £1.50, which is ‘less than Tesco’, priced at £2.75. I need say no more.
So, what is it about this industry which means it is so susceptible to price wars? Are all oligopolies like this? The following articles consider the supermarket industry and the price wars that have emerged. Think about this sector in terms of oligopoly power and consider the questions that follow.

What does it take to create a successful business? From the looks of it: mud, electric barbed wire, icy water, enormous walls to climb, big jumps to make, team work and complete exhaustion – the recipe for every successful business.
Tough Mudder was founded in 2010 and runs gruelling extreme obstacle courses for anyone mad enough to think it might be fun. In the BBC News article below, you’ll see that there is a discussion as to intellectual property rights, but whatever the outcome, this company has become the main provider of such extreme sports in a remarkably short period of time. Within 2 years of being established, it had gained 500,000 participants and now records annual revenues of more than £60m. Add to this, that there has no external funding and this organic growth is beyond impressive.
A key question, then, is what creates such a successful business? Without a doubt, this depends on the product you are selling and the market a firm is in, but there are some aspects that apply across the board. Understanding what your customers want is crucial, as they represent your demand. Differentiating your product to create inelastic demand may be a good strategy to enable price rises, without losing a large number of sales, but the differentiated product is essential in establishing demand, loyalty and reputation. Marketing something in the right way and to the right audience is crucial – word-of-mouth is often the most effective form of advertising.
If you have all of these aspects, then you have the makings of a successful business. The next step is putting it into practice and climbing those high walls, taking the big jumps and hopefully avoiding the mud and ice. The following article considers Will Dean and his fast growing business.

The most commonly used measure of economic performance is GDP and while there is agreement that it is an important and useful measure, there is also agreement that there are some big problems with it. Does it measure welfare or quality of life? What is and isn’t included? Do some things add to GDP which actually make us worse off?
One criticism often levelled at GDP is that there are many aspects that go unmeasured – often known as the underground economy. Some areas are typical everyday things – DIY, looking after your own children rather than paying someone to do it, or even giving yourself a haircut. But, there are other activities, often illegal, which go unrecorded, such as the selling and distribution of drugs and prostitution. In countries like the Netherlands, their GDP figures get a boost, as some drugs and prostitution are legal. In other countries, such data is not recorded and as such, the contribution of these markets is under-estimated or even completely omitted.
However, this aspect of the calculation of GDP statistics is changing across Europe, which will allow much easier and more meaningful comparisons of relative GDP across countries. This extra production will therefore offer a positive contribution towards our GDP and perhaps suggest to the untrained eye that the British economy is growing, which can only be good news. But, for the trained economist, we are looking at extra data being added, which will boost total output and the question will be does it really indicate that the economy is better off? The following articles consider this change to GDP.

The spectre of deflation haunts the eurozone economy. Inflation in the 12 months to May 2014 was 0.5%, down from 0.7% to April and well below the target of 2% (see). Price deflation can result in deflation of the whole economy. With the prospect of falling prices, many consumers put off spending, hoping to buy things later at a lower price. This delay in spending deflates aggregate demand and can result in a decline in growth or even negative growth: hardly a welcome prospect as the eurozone still struggles to recover from the long period of recession or sluggish growth that followed the 2007–8 financial crisis.
The ECB is well aware of the problem. Its President, Mario Draghi, has stated on several occasions that the central bank will do whatever it takes to ward off deflation and stimulate recovery. At its monthly meeting on 5 June, the ECB Council acted. It took the following measures (see Mario Draghi’s press conference and the press release):
• The main refinancing rate it charges banks on reverse repos (when using open-market operations) was cut from 0.25% to 0.15%.
• The rate it pays banks for depositing money in the ECB was cut from 0% to –0.1%. In other words, banks would be charged for ‘parking’ money with the ECB rather than lending it.
• It will provide targeted lending to banks (targeted longer-term refinancing operations (TLTROs)), initially of 7% of the total amount of each banks’ loans to the non-financial private sector within the eurozone. This will be provided in two equal amounts, in September and December 2014. These extra loans will be for bank lending to businesses and households (other than for house purchase). The total amount will be some €400 billion. Substantial additional lending will be made available quarterly from March 2016 to June 2016.
• It will make preparations for an asset purchase scheme. Unlike that in the UK, which involves the purchase of government bonds, this will involve the purchase of assets which involve claims on private-sector (non-financial) institutions. Depending on financing arrangements, this could amount to quantitative easing.
• It will suspend sterilising the extra liquidity that has been injected under the Securities Markets Programme (operated from May 2010 to September 2012), which involved purchasing eurozone countries’ existing bonds on the secondary market. In other words it will stop preventing the securities that have been purchased from increasing money supply. This therefore, for the first time, represents a genuine form of quantitative easing.
The question is whether the measures will be enough to stimulate the eurozone economy, prevent deflation and bring inflation back to around 2%. The measures are potentially significant, especially the prospect of quantitative easing – a policy pursued by other main central banks, such as the Fed, the Bank of England and the Bank of Japan. A lot depends on what the ECB does over the coming months.
The following articles consider the ECB’s policy. The first ones were published before the announcement and look at alternatives open to the ECB. The others look at the actual decisions and assess how successful they are likely to be.

An historic agreement has been reached between Argentina over outstanding debt owed to creditor nations. Creditor nations come together as the ‘Paris Club’ and at a Paris Club meeting on May 28, details of a repayment plan were agreed. Argentina hopes that the agreement will enable it to start borrowing again on international markets: something that had been largely blocked by outstanding debt, which, up to now, Argentina had been unwilling to repay.
The problem goes back to 2001. Argentina was faced with international debt payments of $132bn, equalling some 27% of GDP and over 300% of export earnings. But at the time the country was in recession and debts were virtually impossible to service. It had received some help from the International Monetary Fund, but in December 2001, the IMF refused a request for a fresh loan of $1.3 billion
As Case Study 27.5 in MyEconLab for Economics, 8th edition explains:
This triggered a crisis in the country with mass rioting and looting. As the crisis deepened, Argentina announced that it was defaulting on its $166 billion of foreign debt.
This hardly came as a surprise, however. For many commentators, it was simply a question of when.
Argentina’s default on its debts was the biggest of its kind in history. In a series of dramatic measures, the Argentine peso was initially devalued by 29%. Over the next three months, the peso depreciated a further 40%.
The economy seemed in free-fall. GDP fell by 11% in 2002 and, by the end of the year, income per head was 22% below that of 1998. Unemployment was 21%.
Then, however, the economy began to recover, helped by higher (peso) prices for exports resulting from the currency depreciation. In 2003 economic growth was 9.0% and averaged 8.4% per annum from 2004 to 2008.
But what of the debt? In 2005, Argentina successfully made a huge debt swap with banks and other private creditors (see Box 27.1 in Economics, 8th edition). A large proportion of its defaulted debt was in the form of bonds. It offered to swap the old bonds for new peso bonds, but worth only 35% as much (known as a ‘haircut’). By the deadline of 25 February, there was a 76% take-up of the offer: clearly people thought that 35% was better than nothing! At a stroke, bonds originally worth $104 billion now became worth just $36.2 billion. Later the take-up of the offer increased to 93%. But still 7% held out.
Then in 2006 its debt of nearly $10 billion was repaid to the IMF. General government debt stock as a percentage of GDP fell from 172% in 2002 to 106% in 2006 and to 48% in 2010.
In September 2008, the government of President Cristina Kirchner pledged to use some of its foreign currency reserves of $47 billion to pay back the remainder of the defaulted debt still owed to Paris Club creditors. But negotiations stalled.
However, at the Paris Club meeting of 28 May this year, agreement was finally reached. Argentina will repay the outstanding $9.7bn owed to individual creditor countries. This will take place over 5 years, with a first instalment of $1.15bn being paid before May 2015.
Argentina hopes that the agreement will open up access to overseas credit, which, up to now, has been limited because of this unresolved debt. However, Argentina still owes money to the holders of the 7% of bonds who did not accept the haircut offered in 2005. Their claims are being heard in the US Supreme Court on 12 June this year. The outcome will be critical in determining whether Argentina will be able to raise new funds on the bond market.
