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.

Cloud computing is growing rapidly and has started to dominate many parts of the IT market. Cloud revenues are rising at around 25% per year and, according to Jeremy Duke of Synergy Research Group:

“Major barriers to cloud adoption are now almost a thing of the past, especially on the public-cloud side. Cloud technologies are now generating massive revenues for technology vendors and cloud service providers, and yet there are still many years of strong growth ahead.”

The market leader in cloud services (as opposed to cloud hardware) is Amazon Web Services (AWS), a subsidiary of Amazon. At the end of 2016, it had a market share of around 40%, larger than the next three competitors (Microsoft, Google and IBM), combined. AWS originated cloud computing some 10 years ago. It is set to have generated revenue of $13 billion in 2016.

The cloud computing services market is an oligopoly, with a significant market leader, AWS. But is the competition from other players in the market, including IT giants, such as Google, Microsoft, IBM and Oracle, enough to guarantee that the market stays competitive and that prices will fall as technology improves and costs fall?

Certainly all the major players are investing heavily in new services, better infrastructure and marketing. And they are already established suppliers in other sectors of the IT market. Microsoft and Google, in particular, are strong contenders to AWS. Nevertheless, as the first article states:

Neither Google nor Microsoft have an easy task since AWS will continue to be an innovation machine with a widely recognized brand among the all-important developer community. Both Amazon’s major competitors have an opportunity to solidify themselves as strong alternatives in what is turning into a public cloud oligopoly.

Record fines have been imposed by the European Commission for the operation of a cartel. Truck makers, Volvo/Renault, Daimler, Iveco and DAF have been fined a total of €2.93bn. The fines were considerably higher than the previous record fine of €1.7bn on banks for rigging the LIBOR rate.

Along with MAN, they were found to have colluded for 14 years over pricing. They also colluded in passing on to customers the costs of compliance with stricter emissions rules. Together these five manufacturers account for some 90% of medium and heavy lorries produced in Europe.

The companies have admitted their involvement in the cartel. If they had not, the fines might have been higher. MAN escaped a fine of €1.2bn as it had revealed the existence of the cartel to the Commission.

A sixth company, Scania, is still in dispute with the Commission over its involvement. Thus the final total of fines could be higher when Scania’s case is settled.

In addition, any person or firm adversely affected by the cartel can seek damages from any of the companies in the national courts of member states. They do not have to prove that there was a cartel.

The Commission hopes that the size of the fine will act as a disincentive for other firms to form a cartel. ‘We have, today, put down a marker by imposing record fines for a serious infringement,’ said Margrethe Vestager, the EU’s competition commissioner.

Also, by being able to exempt a cartel member (MAN in this case) from a fine if it ‘blows the whistle’ to the authorities, it will help to break existing cartels.

There are some other major possible cartels and cases of abuse of market power currently being considered by the Commission. These include Google and whether unfair tax breaks were given to Apple and Amazon by Ireland and Luxembourg respectively.

In the following article, Joseph Stiglitz argues that power rather than competition is a better starting point for analysing the working of capitalism. People’s rewards depend less on their marginal product than on their power over labour or capital (or lack of it).

As inequality has widened and concerns about it have grown, the competitive school, viewing individual returns in terms of marginal product, has become increasingly unable to explain how the economy works.

Thus the huge bonuses, often of millions of pounds per year, paid to many CEOs and other senior executives, are more a reflection of their power to set their bonuses, rather than of their contribution to their firms’ profitability. And these excessive rewards are not competed away.

Stiglitz examines how changes in technology and economic structure have led to the increase in power. Firms are more able to erect barriers to entry; network economies give advantages to incumbents; many firms, such as banks, are able to lobby governments to protect their market position; and many governments allow powerful vested interests to remain unchecked in the mistaken belief that market forces will provide the brakes on the accumulation and abuse of power. Monopoly profits persist and there is too little competition to erode them. Inequality deepens.

According to Stiglitz, the rationale for laissez-faire disappears if markets are based on entrenched power and exploitation.

In June 2014, the Gas and Electricity Markets Authority (which governs the energy regulator, Ofgem) referred Great Britain’s retail and wholesale gas and electricity markets to the Competition and Markets Authority (CMA). The market is dominated by the ‘big six‘ energy companies (British Gas, EDF, E.ON, npower, Scottish Power and SSE) and Ofgem suspected that this oligopoly was distorting competition and leading to higher prices.

The CMA presented its report on 10 March 2016. It confirmed its preliminary findings of July and December 2015 “that there are features of the markets for the supply of energy in Great Britain that result in an adverse effect on competition”. It concludes that “the average customer could save over £300 by switching to a cheaper deal” and that “customers could have been paying about £1.7 billion a year more than they would in a competitive market”.

It made various recommendations to address the problem. These include “requiring the largest suppliers to provide fuller information on their financial performance” and strengthening the role of Ofgem.

Also the CMA wants to encourage more people to switch to cheaper suppliers. At present, some 70% of the customers of the big six are on default standard variable tariffs, which are more expensive than other tariffs available. To address this problem, the CMA proposes the setting up of “an Ofgem-controlled database which will allow rival suppliers to contact domestic and microbusiness customers who have been stuck on their supplier’s default tariff for 3 years or more with better deals.”

Another area of concern for the CMA is the 4 million people (16% of customers) forced to have pre-payment meters. These tend to be customers with poor credit records, who also tend to be on low incomes. Such customers are paying more for their gas and electricity and yet have little opportunity to switch to cheaper alternatives. For these customers the CMA proposed imposing transitional price controls from no later than April 2017 until 2020. These would cut typical bills by some £80 to £90 per year. In the meantime, the CMA would seek to remove “restrictions on the ability of new suppliers to compete for prepayment customers and reduce barriers such as debt issues that make it difficult for such customers to switch”.

Despite trying to address the problem of lack of competition, consumer inertia and barriers to entry, the CMA has been criticised for not going further. It has also been criticised for the method it has chosen to help consumers switch to cheaper alternative suppliers and tariffs. The articles below look at these criticisms.
