So here we are, summer is over (or almost over if you’re an optimist) and we are sitting in front of our screens reminiscing about hot sunny days (at least I do)! There is no doubt, however: a lot happened in the world of politics and economics in the past three months. The escalation of the US-China trade war, the run on the Turkish lira, the (successful?) conclusion of the Greek bailout – these are all examples of major economic developments that took place during the summer months, and which we will be sure to discuss in some detail in future blogs. Today, however, I will introduce a topic that I am very interested in as a researcher: the liberalisation of energy markets in developing countries and, in particular, Mexico.
Why Mexico? Well, because it is a great example of a large developing economy that has been attempting to liberalise its energy market and reverse price setting and monopolistic practices that go back several decades. Until very recently, the price of petrol in Mexico was set and controlled by Pemex, a state monopolist. This put Pemex under pressure since, as a sole operator, it was responsible for balancing growing demand and costs, even to the detriment of its own finances.
The petrol (or ‘gasoline’) price liberalisation started in May 2017 and took place in stages – starting in the North part of Mexico and ending in November of the same year in the central and southern regions of the country. The main objective was to address the notable decrease in domestic oil production that put at risk the ability of the country to meet demand; as well as Mexico’s increasing dependency on foreign markets affected by the surge of the international oil price. The government has spent the past five years trying to create a stronger regulatory framework, while easing the financial burden on the state and halting the decline in oil reserves and production. Unsurprisingly, opening up a monopolistic market turns out to be a complex and bumpy process.

Despite all the reforms, retail petrol prices have kept rising. Although part of this price rise is demand-driven, an increasing number of researchers highlight the significance of the distribution of oil-related infrastructure in determining price outcomes at the federal and regional (state) level. Saturation and scarcity of both distribution and storage infrastructure are probably the two most significant impediments to opening the sector up to competition (Mexico Institute, 2018). You see, the original design of these networks and the deployment of the infrastructure was not aimed at maximising efficiency of distribution – the price was set by the monopolist and, in a way that was compliant with government policy (Mexico Institute, 2018). Economic efficiency was not always part of this equation. As a result, consumers located in better-deployed areas were subsidising the inherent logistics costs of less ‘well endowed’ regions by facing an artificially higher price than they would have in a competitive market.
But what about now? Do such differences in the allocation of infrastructure between regions lead to location-related differences in the price of petrol? If so, by how much? And, what policies should the government pursue to address such imbalances? These are all questions that I explore in one of my recent working papers titled ‘Widening the Gap: Lessons from the aftermath of the energy market reform in Mexico’ (with Hugo Vallarta) and I will be sharing some of the answers with you in a future blog.
- Are state-owned monopolies effective in delivering successful market outcomes? Why yes, why no?
- In the case of Mexico, are you surprised about the complexities that were involved with opening up markets to competition? Explain why.
- Use Google to identify countries in which energy markets are controlled by state-owned monopolies.
On 15 January 2018, Carillion went into liquidation. It was a major construction, civil engineering and facilities management company in the UK and was involved in a large number of public- and private-sector projects. Many of these were as a partner in a joint venture with other companies.
It was the second largest supplier of construction and maintenance services to Network Rail, including HS2. It was also involved in the building of hospitals, including the new Royal Liverpool University Hospital and Midland Metropolitan Hospital in Smethwick. It also provided maintenance, cleaning and catering services for many schools, universities, hospitals, prisons, government departments and local authorities. In addition it was involved in many private-sector projects.
Much of the work on the projects awarded to Carillion was then outsourced to other companies, many of which are small construction, maintenance, equipment and service companies. A large number of these may themselves be forced to close as projects cease and many bills remain unpaid.
Many of the public-sector projects in which Carillion was involved were awarded under the Public Finance Initiative (PFI). Under the scheme, the government or local authority decides the service it requires, and then seeks tenders from the private sector for designing, building, financing and running projects to provide these services. The capital costs are borne by the private sector, but then, if the provision of the service is not self-financing, the public sector pays the private firm for providing it. Thus, instead of the public sector being an owner of assets and provider or services, it is merely an enabler, buying services from the private sector. The system is known as a Public Private Partnership.
Clearly, there are immediate benefits to the public finances from using private, rather than public, funds to finance a project. Later, however, there is potentially an extra burden of having to buy the services from the private provider at a price that includes an element for profit. What is hoped is that the costs to the taxpayer of these profits will be more than offset by gains in efficiency.
Critics, however, claim that PFI projects have resulted in poorer quality of provision and that cost control has often been inadequate, resulting in a higher burden for the taxpayer in the long term. What is more, many of the projects have turned out to be highly profitable, suggesting that the terms of the original contracts were too lax.
There was some modification to the PFI process in 2012 with the launching of the government’s modified PFI scheme, dubbed PF2. Most of the changes were relatively minor, but the government would act as a minority public equity co-investor in PF2 projects, with the public sector taking stakes of up to 49 per cent in individual private finance projects and appointing a director to the boards of each project. This, it was hoped, would give the government greater oversight of projects.
With the demise of Carillion, there has been considerable debate over outsourcing by the government to the private sector and of PFI in particular. Is PFI the best model for funding public-sector investment and the running of services in the public sector?
On 18 January 2018, the National Audit Office published an assessment of PFI and PF2. The report stated that there are currently 716 PFI and PF2 projects either under construction or in operation, with a total capital value of £59.4 billion. In recent years, however, ‘the government’s use of the PFI and PF2 models has slowed significantly, reducing from, on average, 55 deals each year in the five years to 2007-08 to only one in 2016-17.’
Should the government have closer oversight of private providers? The government has been criticised for not heeding profit warnings by Carillion and continuing to award it contracts.
Should the whole system of outsourcing and PFI be rethought? Should more construction and services be brought ‘in-house’ and directly provided by the public-sector organisation, or at least managed directly by it with a direct relationship with private-sector providers?

The linked articles below look at the state of the railways in Britain and whether renationalisation would be the best way of securing more investment, better services and lower fares.
Rail travel and rail freight involve significant positive externalities, as people and goods transported by rail reduce road congestion, accidents and traffic pollution. In a purely private rail system with no government support, these externalities would not be taken into account and there would be a socially sub-optimal use of the railways. If all government support for the railways were withdrawn, this would almost certainly result in rail closures, as was the case in the 1960s, following the publication of the Beeching Report in 1963.
Also the returns on rail investment are generally long term. Such investment may not, therefore, be attractive to private rail operators seeking shorter-term returns.
These are strong arguments for government intervention to support the railways. But there is considerable disagreement over the best means of doing so.
One option is full nationalisation. This would include both the infrastructure (track, signalling, stations, bridges, tunnels and marshalling yards) and the trains (the trains themselves – both passenger and freight – and their operation).
At present, the infrastructure (except for most stations) is owned, operated, developed and maintained by Network Rail, which is a non-departmental public company (NDPB) or ‘Quango’ (Quasi-autonomous non-governmental organisation, such as NHS trusts, the Forestry Commission or the Office for Students. It has no shareholders and reinvests its profits in the rail infrastructure. Like other NDPBs, it has an arm’s-length relationship with the government. Network Rail is answerable to the government via the Department for Transport. This part of the system, therefore, is nationalised – if the term ‘nationalised organisations’ includes NDPBs and not just full public corporations such as the BBC, the Bank of England and Post Office Ltd.
Train operating companies, however, except in Northern Ireland, are privately owned under a franchise system, with each franchise covering specific routes. Each of the 17 passenger franchises is awarded under a competitive tendering system for a specific period of time, typically seven years, but with some for longer. Some companies operate more than one franchise.
Companies awarded a profitable franchise are required to pay the government for operating it. Companies awarded a loss-making franchise are given subsidies by the government to operate it. In awarding franchises, the government looks at the level of payments the bidders are offering or the subsidies they are requiring.
But this system has come in for increasing criticism, with rising real fares, overcrowding on many trains and poor service quality. The Labour Party is committed to taking franchises into public ownership as they come up for renewal. Indeed, there is considerable public support for nationalising the train operating companies.
The main issue is which system would best address the issues of externalities, efficiency, quality of service, fares and investment. Ultimately it depends on the will of the government. Under either system the government plays a major part in determining the level of financial support, operating criteria and the level of investment. For this reason, many argue that the system of ownership is less important than the level and type of support given by the government and how it requires the railways to be run.

- Would nationalising the train operating companies be costly to the taxpayer? Explain.
- What determines the optimal length of a franchise under the current system?
- What role does leasing play in investment in rolling stock?
- What are the arguments for and against the government’s decision in November 2017 to allow the Virgin/Stagecoach partnership to pull out of the East Coast franchise three years early because it found the agreed payments to the government too onerous?
- Could the current system be amended in any way to meet the criticisms that it does not adequately take into account the positive externalities of rail transport and the need for substantial investment, while also encouraging excessive risk taking by bidding companies at the tendering stage?
UK productivity growth remains well below levels recorded before the financial crisis, as Chart 1 illustrates. In fact, output per hour worked in 2016 Q3 was virtually the same as in 2007 Q4. What is more, as can be seen from Chart 2, UK productivity lags well behind its major competitors (except for Japan).
But why does UK productivity lag behind other countries and why has it grown so slowly since the financial crisis? In its July 2015 analysis, the ONS addressed this ‘productivity puzzle’.
Among the many reasons suggested are low levels of investment, the impact of the financial crisis on bank’s willingness to lend to new businesses, higher numbers of people working beyond normal retirement age as a result of population and pensions changes, and firms’ ability to retain staff because of low pay growth. While these and other factors may be relevant, they do not provide a complete explanation for the weakness in productivity.
The lack of investment in technology and lack of infrastructure investment have been key reasons for the sluggish growth in productivity. Many companies are prepared to continue using relatively labour-intensive techniques because wage growth has been so low and this reduces the incentive to invest in labour-saving technology.
Another factor has been long hours and, for many office workers, being constantly connected to their work, checking and responding to emails and messages away from the office. The Telegraph article below reports Ann Francke, chief executive of the Chartered Management Institute, as saying:
“This is having a deleterious effect on the health of managers, which has a direct impact on productivity. UK workers already have the longest hours in Europe and yet we’re less productive.”
Another problem has been ultra low interest rates, which have reduced the burden of debt for poor performing companies and has allowed them to survive. It may also have prevented finance from being reallocated to more dynamic companies which would like to develop new products and processes.
Another feature of UK productivity is the large differences between regions. This is illustrated in Chart 3. Productivity in London in 2015 (the latest full year for data) was 31.5% above the UK average, while that in Wales was 19.4% below.
This again reflects investment patterns and also the concentration of industries in particular locations. Thus London’s financial sector, a major part of London’s economy, has experienced relatively large increases in productivity and this has helped to push productivity growth in the capital well above other parts of the country.
Another factor, which again has a regional dimension, is the poor productivity performance of family-owned businesses, where ownership and management is passed down the generations within the family without bringing in external managerial expertise.
The government is very aware of the UK’s weak productivity performance. Its recently launched industrial policy is designed to address the problem. We look at that in a separate post.

Many politicians throughout the world,
not just on the centre and left, are arguing for increased spending on infrastructure. This was one of the key proposals of Donald Trump during his election campaign. In his election manifesto he pledged to “Transform America’s crumbling infrastructure into a golden opportunity for accelerated economic growth and more rapid productivity gains”.
Increased spending on inffrastructure has both demand- and supply-side effects.
Unless matched by cuts elsewhere, such spending will increase aggregate demand and could have a high multiplier effect if most of the inputs are domestic. Also there could be accelerator effects as the projects may stimulate private investment.
On the supply side, well-targeted infrastructure spending can directly increase productivity and cut costs of logistics and communications.
The combination of the demand- and supply-side effects could increase both potential and actual output and reduce unemployment.
So, if infrastructure projects can have such beneficial effects, why are politicians often so reluctant to give them the go-ahead?
Part of the problem is one of timing. The costs occur in the short run. These include demolition, construction and disruption. The direct benefits occur in the longer term, once the project is complete. And for complex projects this may be many years hence. It is true that demand-side benefits start to occur once construction has begun, but these benefits are widely dispersed and not easy to identify directly with the project.
Then there is the problem of externalities. The external costs of projects may include environmental costs and costs to local residents. This can lead to protests, public hearings and the need for detailed cost–benefit analysis. This can delay or even prevent projects from occurring.
The external benefits are to non-users of the project, such as a new bridge or bypass reducing congestion for users of existing routes. These make the private construction of many projects unprofitable, except with public subsidies or with public–private partnerships. So there does need to be a macroeconomic policy that favours publicly-funded infrastructure projects.
One type of investment that is less disruptive and can have shorter-term benefits is maintenance investment. Maintenance expenditure can avoid much more costly rebuilding expenditure later on. But this is often the first type of expenditure to be cut when public-sector budgets as squeezed, whether at the local or national level.
The problem of lack of infrastructure investment is very much a political problem. The politicians who give the go-ahead to such projects, such as high-speed rail, come in for criticisms from those bearing the short-run costs but they are gone from office once the benefits start to occur. They get the criticism but not the praise.
