Last week was a rough week for Britain. The “Beast from the East” and storm Emma swept through the country, bringing with them unusually heavy snowfall, which resulted in severe disruption across nearly all parts of the country. Some recent estimates put the cost of these extreme weather conditions at up to £1 billion per day. The construction industry suffering the biggest hit as work came to a halt for the best part of the week. Losses for the industry were estimated to be up to £2 billion.
Closed restaurants, empty shops and severely disrupted transport networks were all part of the effect that this extreme weather had on the overall economy. According to Howard Archer, chief economic adviser of the EY ITEM Club (a UK forecasting group):
It is possible that the severe weather [of the last few days] could lead to GDP growth being reduced by 0.1 percentage point in Q1 2018 and possibly 0.2 percentage points if the severe weather persist.

As the occurrence of freak weather increases across the globe due to climate change, so does the economic cost of these events. The figure above shows the estimated costs of extreme weather events in the USA between 1980 and 2012 and it is reproduced from Jahn (see link below), who also fits a quadratic trend to show that these costs have been increasing over time. He goes on to characterise the impact of different types of extreme weather (including cold waves, heat waves, storms and others) on different sectors of the local economy – ranging from tourism and agriculture, to housing and the insurance sector.
Linnenluecke et al (linked below) argue that extreme weather caused by climate change could influence the decision of firms on where to locate and could lead to a reshuffle of economic activity across the world and have important policy implications. As the authors explain:
Climate change-related relocation has been given consideration in policy-oriented discussions, but not in management decisions. The effects of climate change and extreme weather events have been considered as peripheral or as a risk factor, but not as a determining factor in firm relocation processes…. This paper therefore [provides] insights for understanding how firms can enhance strategic decision-making in light of understanding and assessing their vulnerability as well as likely impacts that climate change may have on relocation decisions.
The likelihood and associated costs of extreme weather events could therefore become an increasingly important matter for discussion amongst economists and policy makers. Such weather events are likely to have profound economic implications for the world.
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 articles below consider these issues.

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.
What categories of market failure would exist in a purely private rail system with no government intervention?
What types of savings could be made by nationalising train operating companies?
The franchise system is one of contestable monopolies. In what ways are they contestable and what benefits does the system bring? Are there any costs from the contestable nature of the system?
Is it feasible to have franchises that allow more than one train operator to run on most routes, thereby providing some degree of continuing competition?
How are rail fares determined in Britain?
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?
With first Houston, then several Caribbean islands and Florida suffering dreadful flooding and destruction from Hurricanes Harvey and Irma, many are questioning whether more should be spent on flood prevention and reducing greenhouse gas emissions. Economists would normally argue that such questions are answered by conducting a cost–benefit analysis.
However, even if the size of the costs and benefits of such policies could be measured, this would not be enough to give the answer. Whether such spending is justified would depend on the social rate of discount. But what the rate should be in cost-benefit analyses is a highly contested issue, especially when the benefits occur a long time in the future.
I you ask the question today, ‘should more have been spent on flood prevention in Houston and Miami?’, the answer would almost certainly be yes, even if the decision had to have been taken many years ago, given the time it takes to plan and construct such defences. But if you asked people, say, 15 years ago whether such expenditure should be undertaken, many would have said no, given that the protection would be provided quite a long time in the future. Also many people back then would doubt that the defences would be necessary and many would not be planning to live there indefinitely.
This is the familiar problem of people valuing costs and benefits in the future less than costs and benefits occurring today. To account for this, costs and benefits in the future are discounted by an annual rate to reduce them to a present value.
But with costs and benefits occurring a long time in the future, especially from measures to reduce carbon emissions, the present value is very sensitive to the rate of discount chosen. But choosing the rate of discount is fraught with difficulties.
Some argue that a social rate of discount should be similar to long-term market rates. But market rates reflect only the current generation’s private preferences. They do not reflect the costs and benefits to future generations. A social rate of discount that did take their interests into account would be much lower and could even be argued to be zero – or negative with a growing population.
Against this, however, has to be set the possibility that future generations will be richer than the current one and will therefore value a dollar (or any other currency) less than today’s generation.
However, it is also likely, if the trend of recent decades is to continue, that economic growth will be largely confined to the rich and that the poor will be little better off, if at all. And it is the poor who often suffer the most from natural disasters. Just look, for example, at the much higher personal devastation suffered from hurricane Irma by the poor on many Caribbean islands compared with those in comparatively wealthy Florida.
A low or zero discount rate would make many environmental projects socially profitable, even though they would not be with a higher rate. The choice of rate is thus crucial to the welfare of future generations who are likely to bear the brunt of climate change.
But just how should the social rate of discount be chosen? The following two articles explore the issue.
Why does the choice of a lower rate of social discount imply a more aggressive climate policy?
How is the distribution of the benefits and costs of measures to reduce carbon emissions between rich and poor relevant in choosing the social rate of discount of such measures?
How is the distribution of the benefits of such measures between current and future generations relevant in choosing the rate?
How is uncertainty about the magnitude of the costs and benefits relevant in choosing the rate?
What is the difference between Stern’s and Nordhaus’ analyses of the choice of social discount rate?
Explain and discuss the ‘mortality-based approach’ to estimating social discount rates.
What are the arguments ‘for economists analysing climate change through the lens of minimising risk, rather than maximizing utility’?
The car industry has featured heavily in the news in recent weeks with the announcement of plans to ban the sale of new petrol and diesel cars in the UK from 2040. Around the same time, news broke that the European Commission had commenced an investigation into potential collusive behaviour between German car makers.
Since the investigation is ongoing, it is not yet clear exactly what the firms are accused of. However, allegations first published in German magazine Der Spiegel claim that since at least the mid 1990s Volkswagen (and subsidiaries Porsche and Audi), Daimler (owner of Mercedes-Benz) and BMW met several times a year. Furthermore, it is alleged the meetings aimed to give the firms an advantage over overseas rivals by:
co-ordinating the development of their vehicles, costs, suppliers and markets for many years, at least since the Nineties, to the present day.
In particular, Der Spiegel claims that the cartel limited the size of the tanks that manufacturers install in cars to hold chemicals that reduce diesel emissions. Smaller tanks then left more room for the car’s sound system.
Limiting the size of these tanks should be seen in the context of the 2015 emissions scandal where it became clear that Volkswagen had programmed its cars to limit the use of these chemicals and cheated in emissions tests. This meant that 11 million cars worldwide produced excess emissions. Whilst other manufacturers have suggested that the cars they produced may also produce excess emissions, Volkswagen has so far been the only firm to admit to breaking the rules so explicitly. However, if the allegations in Der Spiegel turn out to be true, there will be clear evidence that the harm caused was widespread and that illegal communication between firms played a key role in facilitating this. If found guilty, substantial fines will be imposed by the European Commission and several of the firms have already announced plans to put in place measures to reduce emissions.
It is not clear how the competition authorities discovered the cartel. However, it has been suggestedthat incriminating documents were uncovered during a raid of Volkswagen’s offices as part of an investigation into a separate steel cartel. It seems that Volkswagen and Daimler are now cooperating with the investigation, presumably hoping to reduce the penalties they could face. It has also been reported that Daimler’s role in the investigation will have serious implications for future cooperation with BMW, including a project to develop charging sites for electric cars. It will be extremely interesting to see what the investigation uncovers and what the future ramifications for the car industry are.
