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.

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.

Interest rates have been at record lows across the developed world since 2009. Interest rates were reduced to such levels in order to stimulate recovery from the financial crisis of 2007–8 and the resulting recession. The low interest rates were accompanied by extraordinary increases in money supply under various rounds of quantitative easing in the USA, UK, Japan and eventually the eurozone. But have such policies done harm?
This is the contention of Brian Sturgess in a new paper, published by the Centre for Policy Studies. He maintains that the policy has had a number of adverse effects:
|
• |
There will be nothing left in the monetary policy armoury when the next downturn occurs other than even more QE, which will compound the following problems. |
• |
It has had little effect in stimulating aggregate demand and economic growth. Instead the extra money has been used to repair balance sheets and support unprofitable businesses. |
• |
It has inflated asset prices, especially shares and property, which has encouraged funds to flow to the secondary market rather than to funding new investment. |
• |
The inflation of asset prices has benefited the already wealthy. |
• |
By keeping interest rates down to virtually zero on savings accounts, it has punished small savers. |
• |
By rewarding the rich and penalising small savers, it has contributed to greater inequality. |
• |
By keeping interest rates down to borrowers, it has encouraged households to take on excessive amounts of debt, which will be hard to service if interest rates rise. |
• |
It has lowered the price of risk, thereby encouraging more risky types of investment and the general misallocation of capital. |
Sturgess argues that it is time to end the policy of low interest rates. Currently, in all the major developed economies, central bank rates are below the rate of inflation, making the real central bank interest rates negative.
He welcomes the two small increases by the Federal Reserve, but this should be followed by further rises, not just by the Fed, but by other central banks too. As Sturgess states in the paper (p.12):
In place of ever more extreme descents into the unknown, central banks should quickly renormalise monetary policy. That would involve ending QE and allowing interest rates to rise steadily so that interest rates can carry out their proper functions. Failure to do so will leave the global financial system vulnerable to potential shocks such as the failure of the euro, or the fiscal stresses in the US resulting from the unfinanced spending plans announced by Donald Trump in his presidential campaign.
Although Sturgess argues that the initial programmes of low interest rates and QE were a useful response to the financial crisis, he argues that they should have only been used as a short-term measure. However, if they were, and if interest rates had gone up within a few months, many argue that the global economy would rapidly have sunk back into recession. This has certainly been the position of central banks. Sturgess disagrees.

It is now some seven years since the financial crisis and nearly seven years since interest rates in the USA, the eurozone, the UK and elsewhere have been close to zero. But have these record low interest rates and the bouts of quantitative easing that have accompanied them resulted in higher or lower investment than would otherwise have been the case? There has been a big argument about that recently.
According to conventional economic theory, investment is inversely related to the rate of interest: the lower the rate of interest, the higher the level of investment. In other words, the demand-for-investment curve is downward sloping with respect to the rate of interest. It is true that in recent years investment has been low, but that, according to traditional theory, is the result of a leftward shift in demand thanks to low confidence, not to quantitative easing and low interest rates.
In a recent article, however, Michael Spence (of New York University and a 2001 Nobel Laureate) and Kevin Warsh (of Stanford University and a former Fed governor) challenge this conventional wisdom.
According to them, QE and the accompanying low interest rates led to a rise in asset prices, including shares and property, rather than to investment in the real economy. The reasons, they argue, are that investors have seen good short-term returns on financial assets but much greater uncertainty over investment in physical capital. Returns to investment in physical capital tend to be much longer term; and in the post-financial crisis era, the long term is much less certain, especially if the Fed and other central banks start to raise interest rates again.
“We believe that QE has redirected capital from the real domestic economy to financial assets at home and abroad. In this environment, it is hard to criticize companies that choose ‘shareholder friendly’ share buybacks over investment in a new factory. But public policy shouldn’t bias investments to paper assets over investments in the real economy.”
This analysis has been challenged by several eminent economists, including Larry Summers, Harvard Economics professor and former Treasury Secretary. He criticises them for confusing correlation (low investment coinciding with low interest rates) with causation. As Summers states:
“This is a little like discovering a positive correlation between oncologists and cancer and asserting that this proves oncologists cause cancer. One would expect in a weak recovery that investment would be weak and monetary policy easy. Correlation does not prove causation. …If, as Spence and Warsh assert, QE has raised stock prices, this should tilt the balance toward real investment.”
Not surprisingly Spence and Warsh have an answer to this criticism. They maintain that their critique is less of low interest rates but rather of the form that QE has taken, which has directed new money into the purchase of financial assets. This then has driven further asset purchases, much of it by companies, despite high price/earnings ratios (i.e. high share prices relative to dividends). As they say:
“Economic theory might have something to learn from recent empirical data, and from promising new thinking in behavioral economics.”
Study the arguments of both sides and try to assess their validity, both theoretically and in the light of evidence.

Many UK coal mines closed in the 1970s and 80s. Coal extraction was too expensive in the UK to compete with cheap imported coal and many consumers were switching away from coal to cleaner fuels. Today many shale oil producers in the USA are finding that extraction has become unprofitable with oil prices having fallen by some 50% since mid-2014 (see A crude indicator of the economy (Part 2) and The price of oil in 2015 and beyond). So is it a bad idea to invest in fossil fuel production? Could such assets become unusable – what is known as ‘stranded assets‘?
In a speech on 3 March 2015, Confronting the challenges of tomorrow’s world, delivered at an insurance conference, Paul Fisher, Deputy Governor of the Bank of England, warned that a switch to both renewable sources of energy and actions to save energy could hit investors in fossil fuel companies.
‘One live risk right now is of insurers investing in assets that could be left ‘stranded’ by policy changes which limit the use of fossil fuels. As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.
… As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.’
Much of the known reserves of fossil fuels could not be used if climate change targets are to be met. And investment in the search for new reserves would be of little value unless they were very cheap to extract. But will climate change targets be met?
That is hard to predict and depends on international political agreements and implementation, combined with technological developments in fields such as clean-burn technologies, carbon capture and renewable energy. The scale of these developments is uncertain. As Paul Fisher said in his speech:
‘Tomorrow’s world inevitably brings change. Some changes can be forecast, or guessed by extrapolating from what we know today. But there are, inevitably, the unknown unknowns which will help shape the future. … As an ex-forecaster I can tell you confidently that the only thing we can be certain of is that there will be changes that no one will predict.’
The following articles look at the speech and at the financial risks of fossil fuel investment. The Guardian article also provides links to some useful resources.
