Regulation

Utility and Network Regulation

The regulation of the telecoms, energy and other network industries has huge economic, social and political importance. This note seeks to summarise the key issues and developments, and contains the following sections:

Overview

It is very important to remember that utility regulation is a poor second best to, or substitute for, a properly functioning competitive market. Although regulators are often seen as a useful agent for those who want to change the behaviour of utility industries in various ways, the principal purpose of utility regulation is to limit the economic harm that would occur if these naturally monopolistic industries were not regulated. Such harm would likely include inadequate investment and reduced innovation as well as higher prices, poor service and so on. It is of course possible to ask regulators to assume wider responsibilities, such as helping vulnerable groups or improving the environment, but this generally requires regulators to make trade-offs between their economic and societal objectives, and these decisions are in principle better left to politicians.

It follows that legislators should set tasks and duties for regulators - not outcomes. (Good legislative formulae include phrases such as "... the Commission shall exercise its functions in the manner which it considers is best calculated to further the interests of users ...", "... wherever appropriate by promoting effective competition ...".) Legislators should thus allow competition (or, in its absence, consultation with customers) to determine outcomes which may vary over time, from place to place, and depending on the nature of the company and customer.

It is also important to bear in mind that the network nature of these industries means that there are in principle two quite distinct types of utility/network regulation.

In an ideal world, effective rules regulation does away with the need for output regulation as it facilitates effective competition. This was the logic which drove the electricity regulator to abandon retail price controls in 2002.

The relationship between government, consumer representatives and regulators

The basic rule is that politicians should make social and environmental decisions such as how much to subsidise the phone or energy bill of less affluent consumers, and/or those living in rural areas. Regulators should then implement those decisions when establishing regulatory frameworks and making regulatory decisions. It is in practice difficult to achieve this pure separation as politicians need to understand the detailed impact of their policy choices, and regulators need to be mindful of the unintended consequences of their regulatory decisions, especially for vulnerable customers. There therefore needs to be good communication between regulators and government departments, even if this appears to detract from regulatory independence. But politicians need to remember that - although it is tempting to use regulation as a taxation or redistribution mechanism, as it is easy for subsidies and policy costs to be hidden in regulatory determinations - it is ultimately undemocratic and unreasonable to ask economic regulators to take important social and environmental policy decisions, especially when the regulator's consultation on the choices is less than fully transparent.

Turning to consumer representation, it is generally recognised that, although regulators are pretty good at understanding companies' likely responses to regulation, they do not know enough about how consumers respond to information about prices, quality etc., nor how much customers would be willing to pay for improved service quality etc. This makes it difficult for regulators to construct detailed price controls which inevitably have to prescribe what service has to be provided for a particular price. There is also a good deal of (what is known in the trade as) 'regulatory asymmetry' which takes three main forms:

This leads to quite a dilemma for the regulators. They would generally prefer to act as even-handed arbitrator between consumer representatives on the one hand and utility companies on the other hand, receiving contrasting submissions and making quasi-judicial determinations based on those submissions. But this would disadvantage consumers as the regulated industries would inevitably have much greater power and influence. In practice, therefore, the regulators generally see themselves as representing consumers - or at least the wider public interest - against industry opposition.

One partial solution is 'constructive engagement', first used by the Civil Aviation Authority in setting landing charges etc. - when they asked the airports and the airlines to agree as much as they could (for instance about the need for new investment) in advance of the regulator finalising the price control. It didn't work brilliantly in practice but it was a brave attempt and at least led to sensible and helpful information exchange. The very complex Gas and Electricity Code Modification processes - in which the industry and consumer representatives take the lead in agreeing changes the the rules regulation of these industries - can perhaps be seen as another form of constructive engagement. But these techniques only work if the customers (such as the airlines) are very powerful or the issues relatively uncontroversial. In most other cases it is inevitably necessary for the regulators' staff to ensure that the customer's voice is properly heard by decision makers.

The RPI-X approach to price control

UK regulators generally impose price controls via an 'RPI-X' formula:- prices are allowed to rise in line with the Retail Prices Index less an X% reduction each year to pass on to customers the benefit of improved efficiency. It is generally believed that this formula works well in a wide variety of circumstances, but - by incentivising regular annual price cuts - does it reduce the incentive to innovate and invest, activities which might increase prices in the short term in order to benefit consumers in the longer term?

And it is worth bearing in mind that there are three main players in the regulatory contest: the company, its investors and the regulator. Regulated companies, implicitly - and sometimes explicitly - supported by their owners/investors, will often kick up quite a fuss in the final stages of a price control discussion, claiming that there is no way that the company can meet the regulators' efficiency targets, and trying to browbeat or scare the regulator into making further concessions. But the owners/investors change sides when the new price control kicks in, and will generally put a lot of pressure on the company's managers to cut costs to as to beat the price control and make extra profits - and it is amazing how often the supposedly impossible efficiency targets have in practice been exceeded.

London Underground Public-Private Partnership (PPP) Agreements Arbitration

The PPP Arbiter had the interesting task of acting as 'piggy in the middle' between two sets of monopolists. On the one side there were Metronet Railways and Tube Lines, the companies that ran London's underground railway lines, and on the other side there was their customer, Transport for London (TfL), who are a monopoly supplier of most of London's railway and other transport services.

The PPP itself was always controversial, having been forced on TfL in 2003 by then Chancellor of the Exchequer Gordon Brown. The Government believed that private sector operators would be more efficient, and more willing to stand up to the equally-monopolistic employees and their unions, than public sector TfL. But TfL and others complained that the PPP was extremely and damagingly complex, and (in their view) likely to cost TfL more than if they had run the underground railway lines themselves. One reason for the likely extra cost was that it would cost the private sector companies more than taxpayer-backed TfL to borrow the money to fund the necessary investment in London's ageing railway system. Partial evidence supporting the critics' point of view was the collapse into administration of Metronet in 2007. TfL then took back the running of Metronet's lines. But the Arbiter subsequently found that much of the cost of running the former Metronet lines was higher than the cost of running the remaining private sector Tube Lines lines.

The (as it turned out final) key regulatory development was the Arbiter's decision, in March 2010, that TfL should pay Tube Lines £4,460m over the 7.5 years from 1 July 2010, to include the cost of upgrading the ageing Piccadilly and Northern Lines as required by TfL. TFl said that this was £460m more than they could afford. They therefore needed either to reduce the scope of the work that they wanted Tube Lines to carry out, or somehow find that money. (TfL had hoped that the Arbiter would require Tube Lines to borrow the missing £460m and be paid at a later date, but the Arbiter did not think that this was sensible, as it would cost Tube Lines more to borrow this money than it would cost TfL to do the same thing.) This was followed in May 2010 by TfL's decision to acquire Tube Lines assets for £310m thus bringing an end to this PPP, as well as the Arbiter, its associated regulator. It seemed likely, however, that TfL would then save money by slowing down its rate of spend on upgrading the underground transport system.
