Competition authorities across the globe have recently been paying close attention to the activity of large firms in high-tech markets, in particular Google, Amazon, Facebook and Apple. One estimate suggests that 30 cases have been opened by the authorities since 2010, and a third of these were launched in 2020.

One of the most prominent recent cases in the US courts concerns a complaint made by Epic Games, producer of the popular Fortnite game, against Apple. The background to the case is Apple’s standard practice on its App Store of taking a 30% cut of all paid app and in-app purchases. Therefore, a Fortnite player purchasing $10 worth of in-game currency would result in $7 for Epic and $3 for Apple.

However, in August 2020 Epic decided, contrary to Apple’s terms and conditions, to offer players an alternative way to purchase in-game currency. Gamers would see a choice screen giving them the option to buy currency through the Apple App Store or to buy it directly from Epic. Crucially, purchasing directly from Epic would be cheaper. For example, the same $10 worth of in-game currency on the App Store would cost only $8 if purchased directly from Epic.

It is clear to see why Epic was in favour of direct payments – it earns revenue of $8 instead of $7. However, note that the benefits for gamers are even larger – they save $2 by buying directly. In other words, Epic is passing on 2/3 of the cost saving to consumers.

Apple very quickly responded to Epic’s introduction of the direct purchase alternative by removing Fortnite from the App Store. Epic then filed a complaint with the US District Court.

The Epic v Apple court case

The case concerned Apple restricting game developers’ ability to promote purchasing mechanisms outside the App Store. However, more broadly, it also examined Apple’s complete control of the iOS app market since all apps must be distributed through the Apple App Store. Epic had previously disrupted PC games distribution by launching its own platform with lower fees. The setup of iOS and Apple’s actions against Epic make this an impossible way to reach users.

The Court’s analysis of the Epic v Apple case depended upon several key factors. First, the market definition. To be found to have breached competition law Apple must have a significant share of the market. If the market is defined as that for iOS apps, this is clearly the case. However, if, as Apple argues, it is broader, encompassing the options to play Epic games through web browsers, gaming consoles and PCs, then this is not the case.

Second, even if the market is narrowly defined, Apple argues that its control of the app distribution market is essential to provide user friendly and secure provision of apps. Furthermore, revenue extracted from app producers can enable more investment in the iOS. Without Apple controlling the market, app producers would be able to free-ride on the visibility the App Store provides for their apps.

The ruling

The US Court announced its ruling on 10 September 2021. The judge decided that the market was broader than just iOS and thus Apple is not considered to be a monopolist. This has been touted as a major success for Apple, as it will allow the company to maintain its control of the app distribution market. However, the Court also ruled that Apple must allow game developers to link and direct users to alternative purchasing methods outside the App Store.

The Court’s decision in the Epic v Apple case closely follows concessions recently made by Apple for so called ‘reader apps’ such as Spotify and Netflix. Following an investigation by the Japanese authorities, these concessions allowed such apps to promote and receive purchases directly from consumers as long as they were made outside the app. These apps could be treated differently, as digital goods are consumed on multiple devices. However, the decision in the Epic case now extends such concessions to gaming apps.

It is unclear whether Apple will appeal the decision in the case Epic brought. If not, Apple stands to lose considerable revenue from its 30% share of in-app purchases. It will be very interesting to see how this ruling affects how Apple runs the App Store. Epic, on the other hand, has already made clear it will appeal the decision, aiming to prevent Apple gaining a share of any payment users make outside the app.

Questions

  1. Why might a firm involved in a competition case, such as Apple, try to convince the authorities to define the relevant market as broadly as possible?
  2. Using the example of the Epic v Apple case, explain how Apple’s actions could be seen as both exclusionary and exploitative abuses of a dominant position.

When did you last think about buying a new car? If not recently, then you may be in for a surprise next time you shop around for car deals. First, you will realise that the range of hybrid cars (i.e. cars that combine conventional combustion and electric engines) has widened significantly. The days when you only had a choice of Toyota Prius and another two or three hybrids are long gone! A quick search on the web returned 10 different models (although five of them belong to the Toyota Prius family), including Chevrolet Malibu, VW Jetta and Ford Fusion. And these are only the cars that are currently available in the UK market.

But the biggest surprise of all may be the number of purely (plug-) electric cars that are available to UK buyers these days. The table below provides a summary of total registrations of light-duty plug-electric cars by model in the UK, between 2010 and June 2016.

Source: Wikipedia, “Plug-in electric vehicles in the United Kingdom”

In 2010 there were nly 138 electric vehicles in total registered in the UK. They were indeed an unusual sight at that time – and good luck to you if you had one and you happened to run out of power in the middle of a journey. In 2011 this (small) number increased sevenfold – an increase that was driven mostly by the successful introduction of Nissan Leaf (635 electric Nissans were registered in the UK that year). And since then the number of electric vehicles registered in the country has increased with spectacular speed, at an average rate of 252% per year.

There is clearly strong interest in electric vehicles – an interest likely to increase as their price becomes more competitive. However, they are still very expensive items to buy, especially when compared with their conventional fuel-engine counterparts. What makes electric cars expensive? One thing is the cost of purchasing and maintaining a battery that can deliver a reasonable range. But the cost of batteries is falling, as more and more companies realise the potential of this new market and join the R&D race. As mentioned in a special report that was published recently in the FT:

The cost of lithium-ion batteries has fallen by 75 per cent over the past eight years, measured per kilowatt hour of output. Every time battery production doubles, costs fall by another 5 per cent to 8 per cent, according to analysts at Wood Mackenzie.

There is no doubt that more research will result in more efficient batteries, and will increase the interest in electric cars not only by consumers but also by producers, who already see the opportunity of this new global market. Does this mean that prices will necessarily fall further? You might think so, but then you have to take into consideration the availability and cost of mining further raw materials to make these batteries (such as cobalt, which is one of the materials used in the making of lithium-ion batteries and nearly half of which is currently sourced from the Democratic Republic of Congo). This may lead to bottlenecks in the production of new battery units. In which case, the price of batteries (and, by extension, the price of electric cars) may not fall much further until some new innovation happens that changes either the material or its efficiency.

The good news is that a lot of researchers are currently looking into these questions, and innovation will do what it always does: give solutions to problems that previously appeared insurmountable. They had better be fast because, according to estimates by Wood Mackenzie, the number of electric vehicles globally is expected to rise by over 50 times – from 2 million (in 2017) to over 125 million by 2035.

How many economists does it take to charge an electric car? I guess we are going to find out!

  3. Should the government subsidise the development and production of electric car batteries? Explain the advantages and disadvantages of such intervention and take a position.

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?

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.

Questions

  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?
