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.

Short-term Energy Outlook U.S. Energy Information Administration (EIA) (9/1/18)


  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?

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 UK Parliament’s Culture Media and Sport Select Committee has been examining the secondary ticketing market. The secondary market for events is dominated by four agencies – viagogo, eBay-owned StubHub and Ticket-master’s Get Me In! and Seatwave. These buy tickets to events in the primary market (i.e. from the events or their agents) and then resell them, normally at considerably inflated prices to people unable to get tickets in the primary market.

One example has grabbed the headlines recently. This is where viagogo was advertising tickets for an Ed Sheeran charity concert for £5000. The original tickets were sold for between £40 and £110, with the money going to the Teenage Cancer Trust. None of viagogo’s profits would go to the charity. The tickets were marked ‘not for resale’; so there was doubt that anyone buying a ticket from viagogo would even be able to get into the concert!

There are four major issues.

The first is that the tickets are often sold, as in the case of the Ed Sheeran concert, at many times their face value. We examined this issue back in September 2016 in the blog What the market will bear? Secondary markets and ticket touts).

The second is that the secondary sites use ‘bots’ to buy tickets in bulk when they first come on sale. This makes it much harder for customers to buy tickets on the primary site. Often all the tickets are sold within seconds of coming on sale.

The third is whether the tickets sold on the secondary market are legitimate. Some, like the Ed Sheeran tickets, are marked ‘not for resale’; some are paperless and yet the secondary ticket agencies are accused of selling paper versions, which are worthless.

The fourth is that multiple seats that are listed together are not always located together and so people attending with friends or partners may be forced to sit separately.

These are the issues that were addressed by the Culture Media and Sport committee at its meeting on 21 March. It was due to take evidence from various people, including viagogo, the agency which has come in for the most criticism. Viagogo, however, decided not to attend. This has drawn withering criticism from the press and on social media. One of the other witnesses at the meeting, Keith Kenny, sales and ticketing director for the West End musical Hamilton, described viagogo as ‘a blot on the landscape’. He said, ‘Ultimately, our terms and conditions say ticket reselling is forbidden. If you look at the way that glossy, sneaky site is constructed, they’ve gone an awful long way not to be compliant in the way they’ve built their site.’

The Competition and Markets Authority launched an enforcement investigation last December into suspected breaches of consumer protection law in the online secondary tickets market. This follows on from an earlier report for the government by an independent review chaired by Professor Waterson.

The government itself is considering amending the Digital Economy Bill to make it illegal to use bots to buy tickets in excess of the limit set by the event. Online touts who break this new law would face unlimited fines.

  1. Use a demand and supply diagram to demonstrate how secondary ticket agencies are able to sell tickets for popular events at prices several times the tickets’ face value.
  2. If secondary ticket sites and ticket touts are able to sell tickets at well above box office prices, isn’t this simply a reflection of people’s willingness to pay (i.e. their marginal utility)? In which case, aren’t these sellers providing a useful service?
  3. How do secondary ticket agencies reduce consumer surplus? Could they reduce it to zero?
  4. See Tickets, the primary market ticket agency, has set up a secondary site, whereby fans can trade tickets with one another at a mark-up capped at just 5%. Will this help to reduce abuses on the secondary market, or is it a totally separate part of the market?
  5. Would it be a good idea for event organisers to charge higher prices for popular events than they do at present, but still below the equilibrium?
  6. How does the price elasticity of demand influence the mark-up that secondary ticket agencies can make? Illustrate this on a diagram similar to the one in question 1.
  7. What measures would you advocate to make tickets more available to the public at reasonable prices? Explain their benefits and any drawbacks.
  8. What would be the effect on prices if the use of bots could be successfully banned?

The Competition and Markets Authority (CMA) has imposed a record fine of £84m on the American pharmaceutical manufacturing company Pfizer and of £5.2m on its UK distributor, Flynn Pharma. The CMA found that the companies charged unfair prices to the NHS for phenytoin sodium capsules, the anti-epilepsy drug.

The price was previously regulated, but Pfizer deliberately de-branded the drug in September 2012 and immediately raised the price to Flynn Pharma by between 780% and 1600%, which, in turn, raised the price to the NHS by nearly 2600%. This made the drug many times more expensive than in any other European country.

The cost to the NHS rose from around £2m per year to around £50m in 2013. Although other generic drugs are available, there would be serious health risks to patients forced to switch drugs. The NHS thus had no alternative to paying the higher price.

Pfizer claimed that the drug was loss-making before it was de-branded. However, the CMA calculated that this did not justify the size of the price increase; that the higher price enabled Pfizer to recover all these claimed losses within just two months.

The usual practice is for pharmaceutical companies to charge high prices for new drugs for a period of time to enable them to recover high research and development costs. Later, the drugs become available as generic drugs that other manufacturers can produce. The price then normally falls dramatically.

Phenytoin sodium was invented many years ago and there has been no recent innovation and no significant investment. But, unlike with many other drugs, there has been no switching by the NHS because of possible dangers to patients. This has given Pfizer and its distributor considerable market power. As the CMA states in its press release:

Epilepsy patients who are already taking phenytoin sodium capsules should not usually be switched to other products, including another manufacturer’s version of the product, due to the risk of loss of seizure control which can have serious health consequences. As a result, the NHS had no alternative to paying the increased prices for the drug.

In conclusion, the CMA found that “both companies have held a dominant position in their respective markets for the manufacture and supply of phenytoin sodium capsules and each has abused that dominant position by charging excessive and unfair prices”.

An earlier post on this site described a recent row between Tesco and Unilever that erupted when Unilever attempted to raise the prices it charges Tesco for its products. Unilever justified this because its costs have increased as a result of the UK currency depreciation following the Brexit decision.

It also appears that more general concerns that the fall in the value of sterling would lead to higher retail prices were prevalent around the time that the Tesco Unilever dispute came to light. Former Sainsbury’s boss, Justin King, made clear that British shoppers should be prepared for higher prices. He also said that:

Retailers’ margins are already squeezed. So there is no room to absorb input price pressures and costs will need to be passed on. But no one wants to be the first to break cover. No business wants to be the first to blame Brexit for a rise in prices. But once someone does, there will be a flood of companies because they will all be suffering.

It is interesting to consider further why the Tesco and Unilever case was the first to make the headlines and why their dispute was resolved so quickly. In addition, what are the more general implications for the retail prices consumers will have to pay?

Arguably, Unilever saw itself as having a strong hand in negotiations with Tesco because its product portfolio includes a wide variety of must-stock brands, including Pot Noodles, Marmite and Persil, that are found in 98% of UK households..

Unilever has been criticised for using the currency devaluation as an excuse to justify charging Tesco more, since most of its products are made in the UK. However, Unilever was quick to point outthat commodities it uses in the manufacture of products are priced in US dollars, so the currency devaluation can still affect the cost of products that it manufactures in the UK. In addition, Unilever’s chief financial officer, Graeme Pitkethly, insisted that price increases due to rising costs were a normal part of doing business:

We are taking price increases in the UK. That is a normal devaluation-led cycle.

On the other hand, even if the cost increases faced by Unilever are genuine, it is interesting to speculate whether it would have been so quick to adjust its prices downwards in response to a currency appreciation. After all, a commonly observed phenomenon across a range of markets is ‘rockets and feathers’ pricing behaviour i.e. prices going up from a cost increase more quickly than they go down following an equivalent cost decrease.

Compared to Unilever, some other suppliers are likely to have less bargaining power – in particular, those competing in highly fragmented markets and those producing less branded products. In such markets the suppliers may be forced to accept cost increases. For example, almost 50% of butter and cheese consumed in the UK comes from milk sourced from EU markets. Protecting such suppliers is one of the key roles of the Grocery code of conduct that the UK competition agency has put in place.

From Tesco’s point of view it will have benefited from good publicity by doing its best to protect consumers from price hikes. Helen Dickinson, chief executive of the British Retail Consortium, said:

Retailers are firmly on the side of consumers in negotiating with suppliers and improving efficiencies in the supply chain to control the inflationary pressure that is building through the devaluation of the pound.

However, it is also clear that Tesco had its own motives for resisting increased costs for Unilever’s products. In such situations both supplier and retailer should be keen to avoid a situation where they both impose their own substantial mark-ups at each stage of the supply chain. It is well established that this creates a double mark-up and not only harms consumers, but also the supplier and retailer themselves. Instead, the firms have an incentive to use more complex contractual arrangements to solve the problem. For example, suppliers may pay slotting allowances to get a place on the retailers’ shelves in exchange for lower retail mark-ups.

It has also been claimed that cutthroat competition in the supermarket industry, especially from discounter retailers Aldi and Lidl, made Tesco particularly keen to prevent price rises. Some arguments suggest that these discounters will be best placed to benefit from the currency devaluation as they sell more own brands, have a limited range, the leanest supply chains and benefit from substantial economies of scale. On the other hand, they source more of their products from abroad and it has been suggested that:

A fall in sterling will push prices up for everyone who sources products from Europe, but Aldi and Lidl will be affected more than most.

One prediction suggests that the overall impact of the currency depreciation on food prices will be an increase of around 3%. This may be particularly worrisome given concerns that the impact will fall most heavily on benefit claimants and other low-income households.

Outside of the food industry, Mike Rake, the chairman of BT, has highlighted the fact that:

Imported mobile phones and broadband home hubs were already 10% more expensive and the cost would have to be passed on to consumers in the near future.

It is therefore clear that the currency devaluation has the potential to create substantial tensions in the supply-chain agreements across a range of markets. The impact on the firms involved and on consumers will depend upon a wide range of factors, including the competitiveness of the markets, the nature of the firms involved and their bargaining power. Furthermore, evidence from an earlier currency depreciation in Latin America makes clear that the price elasticity of demand will be another factor that determines the impact price rises have.

Finally, it is also worth noting that a potential flip side of the currency depreciation is a boost for UK exports. However, it has been suggested that the manufacturing potential to take advantage of this in the UK is limited. In addition, even the manufacturing that does take place, for example in the car industry, often relies on components imported from abroad.
