Most real-world markets are a long way from the perfect information setting assumed in perfectly competitive markets. Many industries therefore rely heavily on word of mouth to increase demand. This is especially true in the digital age where information can spread extremely rapidly and many websites encourage consumer ratings and reviews. Here, information becomes more and more valuable as it is shared with other people.
However, the economist Joshua Gans has suggested that traditional business models are not well suited to fully exploiting the benefits of the sharing of information. This is because, whilst enthusiastic consumers spread the word, the seller has traditionally acted as a gate-keeper, maintaining complete control over who obtains the product. The problem is that this creates a friction which can dampen momentum for the product from building.
In contrast, Gans describes a novel alternative strategy that was used by the band the XX when they released their second album earlier this year. As is becoming more and more common, the band premiered the album as an online stream. However, what was unique about the XX’s approach was that they gave the stream to a single superfan. They hoped that this chosen fan would initiate the spreading of the stream amongst other fans. After a worrying delay in which he enjoyed his monopoly ownership, this is what he eventually did. Just 24 hours later the stream had been player millions of times and the site crashed under the burden.
Of course, one reason why suppliers may need close control is to be able to charge for the product. If the sharing information must involve giving something away for free, it typically makes no commercial sense. However, Gans also points out that recommendations are more credible if the information has been costly to obtain. Otherwise, it may simply be cheap talk and therefore carry little value.
The balancing act for suppliers is therefore to introduce a hurdle cost in obtaining the information whilst trying to ensure that, once it has been passed on, the recipient encounters as little friction as possible in making use of it. Gans suggests that alternative business models can be developed which achieve this balance. If these can profitably encourage the sharing of information a win-win situation for sellers and buyers is created.
Furthermore, Gans is experimenting with selling his new book about sharing information under an example of one such model. Having bought the e-book for $4.99 you will find a coupon at the back which you can pass on to a friend or family member which allows them to buy their own copy of the book for a mere $0.99. However, as he points out, there is a potential danger to this strategy:
“All my readers could form a collective and potentially buy one copy for $4.99 and then a million for $0.99.”
He has said that he plans to be report back on how the book has sold on his blog at a later date, so it will be interesting to see whether or not the experiment was successful.

The energy sector has a history of criticism with regards to prices and practices. In the past, Ofgem have tried to make the sector more competitive, by ensuring that price comparisons are easier. At the beginning of this year, many of the big six providers announced price cuts, but within the next few weeks, we will see the reverse occurring, as energy prices begin to rise.
British Gas has announced price rises of 6% from 16th November that will affect over 8 million customers by adding approximately £80 per year to the annual dual fuel bill. Npower will also put its prices up 10 days later (8.8% for gas and 9.1% for electricity), creating higher bills for 3 million people.
In January of this year, when we saw energy prices fall, it was not solely due to Ofgem’s findings. We had a relatively mild winter, which reduced the demand for energy and this fed into lower prices. As the winter now approaches once more, demand for energy will begin to increase, feeding into prices that are now higher.
Furthermore, the energy companies have said that a range of external factors are also adding to their costs and putting increasing pressure on them to increase their charges. Npower’s Chief Commercial Officer said:
“There is never a good time to increase energy bills, particularly when so many people are working hard to make ends meet…But the costs of new statutory schemes, increases in distribution charges and the price of gas for the coming winter are all being driven up by external factors, for example government policy”
Significant investment is needed in the energy sector. Energy companies are required to set aside money for maintaining and improving the national grid and investing in renewable energy, such as wind and solar power. In order for the energy companies to fund these investments, more money must be raised and the logical method is to put up prices. However, critics are simply blaming ‘these very big lazy companies’ who are passing ‘above-inflation price rises’ onto already squeezed households.
Part of this is undoubtedly to do with the market structure of this sector. A typical oligopoly creates a market which, under certain circumstances, can be highly competitive, but because of barriers to entry that prevent new firms from entering the market may charge higher prices and be inefficient. Indeed, Ofgem has plans to reduce the power of the main energy providers by forcing them to auction off some of the electricity they generate. The aim of this is to free up the market and make it more competitive.
While only three providers have announced price rises, it is inevitable that the other three will follow. The relative increases will create incentives for consumers to switch providers, but crucial to this is an ability to understand the different tariffs on offer and lack of clarity on this has been a big criticism previously levelled at the energy sector. Indeed, half of UK customers have never switched energy providers. Perhaps this is the time to think about it, firstly as a means of saving money and secondly as a means of putting the energy companies in competition with each other. The following articles consider this market.

When crude oil prices go up, the prices of petrol and diesel go up pretty well straight away and by the full amount, or more, of the crude price rise. When crude prices go down, however, road fuel prices are often slow to fall; and when they do, the fall is less than the full fall in crude prices.

In response to complaints of motorists and haulage companies, the Office of Fair Trading has announced that it will investigate the link between crude prices and prices at the pump. It will report in January 2013.
The review will consider questions of competition and market power. In particular, it will look at the power of the oil companies in determining the wholesale price of road fuel.
It will also examine the retail fuel sector and whether supermarkets are driving out independent retailers. The claim of many independent petrol stations is that supermarkets are selling below cost as a lost leader to encourage people to shop in their stores. They also claim that supermarkets use their buying power to obtain fuel more cheaply.
What is more, most of the petrol stations that are not part of supermarkets are owned by the oil companies. Again, independents claim that oil companies supply fuel more cheaply to their own stations than to independents.
As a result of what many independents see as unfair competition, many are driven out of business. Today there some 9000 petrol stations in the UK; 20 years ago there were twice as many.
The following articles look at the remit of the OFT investigation and at the competition issues in the road fuel market.

Last year, an academic discovered that the only two firms on Amazon selling new copies of a classic biology textbook were charging well over $1 million (plus $3.99 for shipping!). Furthermore, when he checked the next day, prices had risen even further to nearly $2.8 million! Intrigued by this strange pricing behaviour, he started to investigate the prices further.
In oligopoly markets with a small number of players, firms must make strategic decisions taking into account how they expect their rivals will react. One option in today’s online market places is for firms to use computer algorithms which automatically adjust their prices according to the prices their rivals are charging. The results of his investigation suggested that this was exactly what was causing the prices for this textbook to be so high.
One of the firms appeared to adopt a pricing rule which set its price at 0.9983 times the price of the other firm. This seems to make sense – this firm wants to undercut its rival in order to be more likely to sell its copy. However, if both firms operated under this strategy, we would expect to see prices falling over time (see also). In contrast, the strategy of the other firm appeared to be to price 1.270589 above its rival’s price. Why would it want to try to make sure it was always more expensive that its rival? The academic’s plausible explanation was that:
“…they do not actually possess the book. Rather, they noticed that someone else listed a copy for sale, and so they put it up as well – relying on their better feedback record to attract buyers. But, of course, if someone actually orders the book, they have to get it – so they have to set their price significantly higher – say 1.27059 times higher – than the price they’d have to pay to get the book elsewhere.”
Put both of these pricing rules together and prices will continuously rise over time! This was exactly what the academic observed for over a week, until human intervention appears to have returned prices to a more sensible level.
As Tim Harford discusses in his recent blog post, it had been hoped that online market places would result in very low prices because the high degree of price transparency increases competition. Clearly the prices Amazon was initially charging for the textbook didn’t support this theory and even after human intervention prices would seem to be well above marginal production costs. However, as the blog post goes on to explain, we should not necessarily expect price transparency always to lead to low prices. Economic theory shows us that in oligopoly markets, when a small number of players interact repeatedly, they may be able to collude tacitly on high prices. Furthermore, a high degree of price transparency may help such collusive behaviour because it makes it easier for firms to detect cheating by a rival.

Questions
- What are the key features of competition between book sellers on Amazon?
- What price setting rule would the two firms have to use for prices to continuously fall over time? Provide an illustrative example.
- What are the pros and cons for a firm of relying on a computer algorithm to set its prices?
- How might a firm program its price setting algorithm if it wanted to collude tacitly with its rivals?
- Can you think of any other explanations for the pricing strategies that the two Amazon sellers adopted?
In oligopoly markets, because there are a small number of firms, each firm is affected by its rivals’ decisions. This interdependence results in a tension between cooperation and competition. On the one hand, firms collectively benefit from cooperating and keeping prices high.
On the other hand, an individual firm then has an incentive to undercut its rivals to steal a larger share of the market. This incentive to undercut can potentially result in price wars between firms. This is exactly what has recently occurred between pizza sellers on the Avenue of Americas in Midtown New York. Here, until recently the 6th Ave. Pizza company was selling pizza for $1.50 per slice. However, the entry of two competitors nearby sparked an intense and bitter price war.
First, an outlet called Joey Pepperoni’s Pizza opened nearby and charged $1 per slice. This price was then matched by the 6th Avenue Pizza company. Then, the 2 Bros. pizza chain opened an outlet almost next door to the 6th Avenue Pizza company. Initially, they also charged $1 per slice.
However, this did not last for too long. First 6th Avenue cut its price to 79 cents and then 2 Bros. responded by cutting its price to 75 cents, which 6th Avenue quickly matched.
Which company started this price war has been subject to some debate. The owners of the 6th Avenue Pizza company were angry, alleging that 2 Bros. was trying to force them out of business. However, the owners of 2 Bros. claimed that they were simply responding to the 6th Avenue Pizza company’s decision to start charging 79 cents per slice and they even have evidence from their security cameras confirming this! When asked why they cut their price the owners of the 6th Avenue company said that:
He was taking away our customers. How were we going to pay our rent?
So what will happen next in this market? One of the owners of the 2 Bros. company has said that they will go back to $1 per slice if the 6th Avenue Pizza company does the same, as they can’t make any profit at the current price. However, the tension between cooperation and competition suggests this may be difficult to sustain.
In the meantime, both are quoted suggesting that they may be tempted to reduce prices even further. 6th Avenue Pizza company stated:
We may go to 50 cents. I want to hit him. I want to beat him.
2 Bros. said:
We might go to free pizza soon.
Of course, while the price war continues, the clear winners are the consumers. In the article one is quoted as saying:
I think it’s beautiful. We need 75-cent hamburgers next.
