Category: Essential Economics for Business: Ch 05

In the last few years there have been growing concerns (see here for example) that markets in the USA are becoming increasingly dominated by a small number of firms. It is feared that the result of this will be a reduction in competition. Consistent with this, evidence suggests that the profits these firms make have increased. Last month The Economist and the Resolution Foundation published evidence (see references below) suggesting a similar picture may be emerging in Britain.

The Economist divided the British economy into 600 sub-sectors and found that in 58% of these the share of total revenue accruing to the 4 biggest firms had increased since 2008. The Resolution Foundation found a similar picture, especially in manufacturing industries where from 2004-16 the top five firms’ share of total revenue increased by over 10%.

Economic theory would suggest that as markets become more concentrated prices are likely to rise and The Economist cites research showing that mark-ups charged by firms in Britain have indeed risen. In addition to consumers facing higher prices, there is also concern that the lack of competition both in the USA and the UK is leading to lower wages being paid to workers. On the other hand, unlike in the USA, the evidence from the UK does not so far suggest there has also been an increase in corporate profits. Instead, it appears that the more successful firms’ profits have increased at the expense of their rivals.

This evidence on profits is line with a number of arguments that suggest we should perhaps be less concerned when markets are dominated by a small number of firms. Large firms may benefit from economies of scale and, being sufficiently large may be necessary for firms to innovate in new products and processes. Furthermore, high market shares may result from the competitive process as a reward for a firm developing a unique product or being more efficient than its rivals.

The Economist cites the supermarket industry as an example where concentrated is high, but competition is intense. Interestingly, this is a market where the British competition authorities have previously been concerned about the level of competition and spent considerable amounts of time investigating.

Despite these two opposing viewpoints, overall, The Economist argues strongly that we should be concerned about the situation in Britain. Not only are prices too high and wages too low, but growth in productivity is slow, even for the leading firms. Furthermore, they make clear that the situation may worsen following Brexit. It is argued that:

leaving the EU’s single market and customs union would reduce trade, easing competitive pressure from abroad.

This is consistent with evidence that joining the EC in the mid 1970s increased foreign competition in the UK and helped to end the low productivity growth that had plagued the economy since the 1930s.

Furthermore, it is suggested that:

to attract investment the government might look more favourably on proposed mergers—and loosening regulations would be easier outside the EU’s competition regime.

Therefore, it is clear that in the future there will be a vital role for the UK’s competition authority to remain independent of political objectives and aim to promote competition. In particular, they must prevent mergers that raise concentration and harm competition and intervene if they believe firms are abusing their dominant positions. Of course, following Brexit the case load of the competition authority in the UK will increase dramatically as they have to take on cases previously dealt with by the European Commission. One estimate is that it will need to look at around 40% more merger cases. It will certainly be interesting to see how competition in markets in Britain evolves over the next few years and the role competition policy plays in regulating this process.

OPEC, for some time, was struggling to control oil prices. Faced with competition from the fracking of shale oil in the USA, from oil sands in Canada and from deep water and conventional production by non-OPEC producers, its market power had diminished. OPEC now accounts for only around 40% of world oil production. How could a ‘cartel’ operate under such conditions?

One solution was attempted in 2014 and 2015. Faced with plunging oil prices which resulted largely from the huge increase in the supply of shale oil, OPEC refused to cut its output and even increased it slightly. The aim was to keep prices low and to drive down investment in alternative sources, especially in shale oil wells, many of which would not be profitable in the long term at such prices.

In late 2016, OPEC changed tack. It introduced its first cut in production since 2008. In September it introduced a new quota for its members that would cut OPEC production by 1.2 million barrels per day. At the time, Brent crude oil price was around $46 per barrel.

In December 2016, it also negotiated an agreement with non-OPEC producers, and most significantly Russia, that they would also cut production, giving a total cut of 1.8 million barrels per day. This amounted to around 2% of global production. In March 2017, it was agreed to extend the cuts for the rest of the year and in November 2017 it was agreed to extend them until the end of 2018.

With stronger global economic growth in 2017 and into 2018 resulting in a growth in demand for oil, and with OPEC and Russia cutting back production, oil prices rose rapidly again (see chart: click here for a PowerPoint). By January 2018, the Brent crude price had risen to around $70 per barrel.

Low oil prices had had the effect of cutting investment in shale oil wells and other sources and reducing production from those existing ones which were now unprofitable. The question being asked today is to what extent oil production from the USA, Canada, the North Sea, etc. will increase now that oil is trading at around $70 per barrel – a price, if sustained, that would make investment in many shale and other sources profitable again, especially as costs of extracting shale oil is falling as fracking technology improves. US production since mid-2016 has already risen by 16% to nearly 10 million barrels per day. Costs are also falling for oil sand and deep water extraction.

In late January 2018, Saudi Arabia claimed that co-operation between oil producers to limit production would continue beyond 2018. Shale oil producers in the USA are likely to be cheered by this news – unless, that is, Saudi Arabia and the other OPEC and non-OPEC countries party to the agreement change their minds.

Questions

  1. Using supply and demand diagrams, illustrate what has happened to oil prices and production over the past five years. What assumptions have you made about the price elasticity of supply and demand in your analysis?
  2. If the oil price is above the level at which it is profitable to invest in new shale oil wells, would it be in the long-term interests of shale oil companies to make such investments?
  3. Is the structure of the oil industry likely to result in long-term cycles in oil prices? Explain why or why not.
  4. Investigate the level of output from, and investment in, shale oil wells over the past three years. Explain what has happened.
  5. Would it be in the interests of US producers to make an agreement with OPEC on production quotas? What would prevent them from doing so?
  6. What is likely to happen to oil prices over the coming 12 months? What assumptions have you made and how have they affected your answer?
  7. If the short-term marginal costs of operating shale oil wells is relatively low (say, below $35 per barrel) but the long-term marginal cost (taking into account the costs of investing in new wells) is relatively high (say, over $65 per barrel) and if the life of a well is, say, 5 years, how is this likely to affect the pattern of prices and output over a ten-year period? What assumptions have you made and how do they affect your answer?
  8. If oil production from countries not party to the agreement between OPEC and non-OPEC members increases rapidly and if, as a result, oil prices start to fall again, what would it be in OPEC’s best interests to do?

Together with Formula 1, tennis is the other sport I love – and my favourite player by far is Rafa!

We often apply game theory to various sports and consider how players, teams and individuals can think strategically. One of the big debates in tennis is ‘who is the best ever’ and I argue that Nadal is the greatest, based on a huge range of metrics.

I saw this article in the Economist, providing analysis and comparison between some of the best tennis players. It shows how we can use economic thinking, probability, game theory and analysis to come to something of an answer about who is the greatest, considering the various players’ runs to the title in the Grand Slams. Of course the reason I’m posting this is because according to the Economist, Rafa is the best! And the reasoning is very sound. Enjoy. I certainly did.

  2. How does the rating system aim to measure the skill of a tennis champion?
  3. In this particular scenario, why is it important to use probabilities?
  4. We can use game theory to think about penalty shoot outs and whether footballers play to the Nash equilibrium. Can we also use the Nash equilibrium when thinking about tennis? (Think about the serve!)

Following concerns about the market power of the Big Six energy suppliers in the UK and high prices for gas and electricity, the industry regulator, Ofgem, referred the industry to the Competition and Markets Authority (CMA) in June 2014. The CMA published its final report in June 2016. This argued that while there was sufficient potential for competition, consumers nevertheless needed further encouragement to switch suppliers. This would strengthen competition in the market.

To encourage switching, the CMA proposed the creation of a database that would include the details of customers who have been on a supplier’s standard variable tariff (SVT) for three or more years. Competitor energy suppliers would have access to this database to offer better deals for these customers.

There had already been calls for price caps to be imposed on suppliers. For example, in the run-up to the 2015 general election, the then Labour leader, Ed Miliband, proposed imposing a price freeze. This was criticised by the Conservatives for being too anti-market, that it would encourage energy companies to raise prices prior to the freeze and that it would be of no benefit in times of falling wholesale energy prices (which was the position in 2015).

Indeed, in its 2016 report, the CMA recommended price caps only for the 16% of people on prepayment meters and these would be variable caps not freezes. This was followed in February 2017, by Ofgem’s announcement that a temporary price cap for such customers would come into effect in April 2017. The level of the cap would vary by meter type and region. It would also be reviewed every six months to reflect changes in costs and remain in place until 2020. There would be no cap on other customers.

But in the run-up to the 2017 election, the Conservatives announced that they would, after all, introduce a price cap on SVTs – 66% of customers are on such tariffs. Before the details were announced, there was much speculation as to what form such a cap would take? It would not be a simple freeze. But there was debate as to whether caps would vary with wholesale costs or whether they would be relative to the company’s lowest tariffs or to those of its rivals.

As it turned out, the proposal was for a cap on standard variable tariffs. It would be set by Ofgem and reviewed every six months. The cap would be based on the cheapest standard variable tariffs in each part of the UK, taking into account the variable costs for transporting energy there. Ofgem will adjust the cap every six months to reflect changes in the wholesale cost of energy.

The term ‘Google it’ is now part of everyday language. If there is ever something you don’t know, the quickest, easiest, most cost-effective and often the best way to find the answer is to go to Google. While there are many other search engines that provide similar functions and similar results, Google was revolutionary as a search engine and as a business model.

This article by Tim Harford, writing for BBC News, looks at the development of Google as a business and as a search engine. One of the reasons why Google is so effective for individuals and businesses is the speed with which information can be obtained. It is therefore used extensively to search key terms and this is one of the ways Google was able to raise advertising revenue. The business model developed to raise finance has therefore been a contributing factor to the decline in newspaper advertising revenue.

Google began the revolution in terms of search of engines and, while others do exist, Google is a classic example of a dominant firm and that raises certain problems. The article looks at many aspects of Google.
