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.

A modern day hindrance is spam email clogging up your inbox with, for example, offers for cheap drugs or notifications that you will inherit enough money to retire to the Bahamas. A recent paper by Justin Rao and David Reiley in the Journal of Economic Perspectives investigates the economics of spam mail (which, as I discovered, from the article gets it’s name from a Monty Python sketch). Remarkably, they quote figures suggesting that 88% of worldwide email traffic is spam. Their paper then provides a number of interesting insights into the business of spam mail.

First, given that most recipients simply delete it, why is spam mail sent out? For the benefits of sending it to exceed the costs, it must be that somebody is reading and responding to it and the costs must also be reasonably low. Rao and Reiley are able to quantify these costs and benefits. They estimate that if 8.3 million spam emails are sent, only 1.8% (approximately 150,000) will reach the intended recipients’ inboxes, with the remainder being blocked or filtered out. Of these 150,000, just 0.25% (375) are clicked on. Furthermore, these 375 clicks generate just a single sale of the advertised product which is typically sold for around $50. Assuming that free entry of spammers leads to them earning zero economic profit, this means that it costs the spammers around $50 to send the 8.3 million emails.

Second, spam mail clearly imposes a considerable negative externality on society. This includes wasted time for consumers and the costs of the extra server hardware capacity required. Rao and Reiley are also able to quantify the size of the negative externality created. First, they estimate that:

“American firms and consumers experience costs of almost $20 billion annually due to spam.”

This can then be compared to the benefits senders of spam get:

“….. we estimate that spammers and spam-advertised merchants collect gross worldwide revenues on the order of $200 million per year. Thus, the ‘externality ratio’ of external costs to internal benefits for spam is around 100:1.”

They then compare this to estimates for other negative externalities such as car pollution and conclude that the size of the negative externality from spam is significantly greater.

Finally, they also point out that it is predominantly the larger email service providers i.e. Yahoo! Mail, Microsoft Hotmail, and Google Gmail who have both the incentives and resources to fund interventions to eradicate spam. For example, in 2009 Microsoft and Pfizer (the manufacturer of Viagra which faces competition from counterfeit versions often advertised by spam) financially supported the successful operation to shut down the largest spam distributor. Clearly, such operations have large positive spillovers for email users. However, as they also discuss, anti-spam technology also increases the fixed costs of competing as an email provider and they suggest that this has contributed to the increased concentration in the market.

After weak Christmas trading, Tesco issued a profit warning – its first in 20 years. Following this, their shares fell in value by some £5bn, but this was met with an announcement of the creation of 20,000 jobs in the coming years, as part of a project to train staff, improve existing stores and open new ones. Yet, Tesco has reported another quarter of falling sales.

Trading times have been challenging and the fact that the UK’s biggest supermarket is struggling is only further evidence to support this. In the 13 weeks to the 26th May 2012, Tesco reported a decline in like-for-like sales of 1.5%. Although much of the £1bn investment in Tesco is yet to be spent, the fact that sales have fallen for a full year must be of concern, not only to its Chief Executive, but also to analysts considering the economic future for the UK.

Consumer confidence remains low and together with tight budgets, shoppers are continuing to be very cautious of any unnecessary spending. Part of Tesco’s recent drive to drum up sales has been better customer service and a continuing promotion war with the other supermarkets. This particular sector is highly competitive and money-off coupons and other such promotions plays a huge part in the competitive process. Whilst low prices are obviously crucial, this is one sector where non-price competition can be just as important.

Although Tesco sales in the UK have been nothing to shout about – the Chief Executive said their sales performance was ‘steady’ – its total global sales did increase by 2.2%. The Chief Executive, Mr Clarke said:

‘Internationally, like-for-like sales growth proved resilient, despite slowing economic growth in China…Against the backdrop of continued uncertainty in the eurozone, it is pleasing to see that our businesses have largely sustained their performance.’

A boost for UK sales did come with the Jubilee weekend and with the Olympics just round the corner, Tesco will be hoping for a stronger end to the year than their beginning. The following articles consider Tesco’s sales and the relative performance of the rest of the sector.

Vodafone has offered to purchase Cable & Wireless Worldwide (C&WW), with Vodafone paying 38p per share, making this deal worth £1.044bn.

This deal, however, was rejected by C&WW’s largest shareholder, Orbis, within hours, as the price was not high enough, despite the 38p per share offer representing a 92% premium to the level of C&WW’s share price before the bid interest emerged in February. A spokesperson for Orbis said:

‘Although we believe the C&WW management team has handled the bid process responsibly, we have declined to give an irrevocable undertaking or letter of intent to the support the transaction.’

However, with the only other interested party, Tata Communications withdrawing, Vodafone was the only remaining bidder. As such, many suggest that this deal is a good one for the struggling business, despite Orbis’ claim that it under-values the business.

Adding a UK fixed-line cable to Vodafone’s business will increase its capacity, which is much needed at this moment in time with the added demand for mobile data from increased Smartphone usage. Cost savings are also expected from this merger, as the company will no longer have to pay to other companies to lease its fixed-line capacity.

The bid from Vodafone did help C&WW’s trading performance, which had been worsening for some time and so some shareholders will be glad of the bid. Its shares were up following this deal and it went to the top of the FTSE250. Vodafone will also benefit, as this merger would make it the second largest combined fixed and mobile line operator in the UK.

The trends of these two companies in recent years have been very much in contrast. C&WW had been the larger of the two firms up until 1999, yet the price Vodafone would now pay for the company represents a mere 1% of its current market value. The following articles consider this merger.

Last year, we felt the cost of the cold weather and whilst we haven’t seen such low temperatures this year, gas shortages are also emerging. Across Eastern Europe, temperatures have fallen well below -30ºC and so demand for gas has unsurprisingly increased.

Thanks to these low temperatures, Russian gas supplies are running low and several countries have seen their deliveries of gas fall. However, the Russian gas monopoly, Gazprom has said that supplies have not been cut and that it has been exporting more gas during these cold times. The blame, according to Alexander Medvedev (the Deputy CEO of Gazprom), lies with the Ukraine taking gas at a pace significantly above contracted levels. The following articles consider this issue.
