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 UK is a productivity laggard. Compared to many developed countries over the recent past it has experienced weaker growth in output per worker and output per hour worked. This is detrimental to our longer-term well-being and to peoples’ living standards. An important contributory factor has been the weakness of growth in (non-financial) capital per worker. Recent ONS figures show that UK experienced a decline in capital per worker from 2012 to 2015, which was only ended in 2016.

Non-financial capital assets (also known as fixed assets) are defined as already-produced, durable goods or any non-financial asset used in the production of goods or services. This includes items such as dwellings, buildings, ICT, machinery and transport equipment.

Chart 1 shows the value of net capital assets in the UK since 1995. ‘Net’ figures account for the depreciation of assets and so reflect the market value of the capital stock. At the end of 2016 the net capital stock was estimated at £7.54 trillion (at 2015 prices) compared to £4.94 trillion (at 2015 prices) in 1995, an increase of 53 per cent or about 2.4 per cent per year.

However, as the chart shows, the rate of growth slowed markedly following the financial crisis of the late 2000s, averaging a mere 0.8 per cent per year since 2010. (Click here for a Powerpoint of the chart).

Capital intensity can be measured by the amount of capital per employee. Capital intensity is important because the growth in net capital per employee impacts on productivity. Its growth has an impact on the current effectiveness of capital and labour in production and on the future growth in potential output per employee.

Chart 2 shows that, following the financial crisis, falling employment levels temporarily boosted the growth in net capital per employee. Then, as employment levels recovered and began growing again, the weakness in investment meant that net capital per employee began to fall.

In 2016, as employment growth slowed, the now stronger flows of investment meant that, for the first time since 2011, net capital per employee was finally rising again. (Click here for a PowerPoint of the chart).

The persistent weakness experienced by UK in the growth of capital intensity in the 2010s is a drag on productivity and on supply-side growth. The weakness of UK productivity growth looks like remaining for some time one of the biggest economic challenges facing policymakers. Productivity needs its capital.

Where you live in Great Britain can have a profound effect on your earning potential. According to a report published by the Social Mobility Commission, there is a growing geographical divide, with more affluent areas getting relatively richer, while ‘many other parts of the country are being left behind economically and hollowed out socially’.

The Commission uses a Social Mobility Index to rank the 324 local authorities in England. The index is a measure of the social mobility prospects for people from disadvantaged backgrounds. It is ‘made up of 16 key performance indicators spanning each major life stage’.

The index shows that children from disadvantaged backgrounds have lower educational attainment, poorer initial jobs and poorer prospects for advancement in the labour market. Often they are stuck in low paid jobs with little chance of getting on the housing ladder and fewer chances of moving away from the area.

The problem is not simply one of a North-South divide or one of inner cities versus the suburbs. Many inner-city areas have been regenerated, with high incomes and high social and geographical mobility. Other inner-city areas remain deprived.

The worst performing areas are remote rural or coastal areas and former industrial areas, where industries have closed. As the author of the report states in the Guardian article linked below:

These areas have fewer specialist teachers, fewer good schools, fewer good jobs and worse transport links. … Many of these areas have suffered from a lack of regeneration: few high-paying industries are located there, and they often exhibit relatively limited job opportunities and clusters of low pay.

The problem often exists within areas, with some streets exhibiting growing affluence, where the residents have high levels of social mobility, while other streets have poor housing and considerable levels of poverty and deprivation. Average incomes for such areas thus mask this type of growing divide within areas. Indeed, some of the richest areas have worse outcomes for disadvantaged children than generally poorer areas.

There are various regional and local multiplier effects that worsen the situation. Where people from disadvantaged backgrounds are successful, they tend to move away from the deprived areas to more affluent ones, thereby boosting the local economy in such areas and providing no stimulus to the deprived areas. And so the divide grows.

Policies, according to the report, need to focus public investment, and incentives for private investment, in deprived areas. They should not focus simply on whole regions. You can read the specific policy recommendations in the articles below.

In delivering his Budget on 22 November, Philip Hammond reported that the independent Office for Budget Responsibility had revised down its forecasts of growth in productivity and real GDP, and hence of earnings growth.

Today, median earnings are £23,000 per annum. This is £1500 less than the £24,500 that the median worker earned in 2008 in today’s prices. The OBR forecasts a growth in real household disposable income of just 0.35% per annum for the next four years.

With lower growth in earnings would come a lower growth in tax revenues. With his desire to cut the budget deficit and start eventually reducing government debt, this would give the government less scope for spending on infrastructure, training and other public-sector investment; less scope to support public services, such as health and education; less scope for increasing benefits and public-sector wages.

The normal measure of productivity, and the one used by the OBR, is the value of output produced per hour worked. This has hardly increased at all since the financial crisis of 2008. It now takes an average worker in the UK approximately five days to produce the same amount as it takes an average worker in Germany four days. Although other countries’ productivity growth has also slowed since the financial crisis, it has slowed more in the UK and from a lower base – and is now forecast to rebound less quickly.

For the past few years the OBR has been forecasting that productivity growth would return to the trend rate of just over 2% that the UK achieved prior to 2008. For example, the forecasts it made in June 2010 are shown by the grey line in the chart, which were based on the pre-crash trend rate of growth in productivity (click on chart to enlarge). And the forecasts it made in November 2016 are shown by the pale green line. Yet each year productivity has hardly changed at all. Today output per hour is less than 1% above its level in 2008.

Now the OBR believes that poorer productivity growth will persist. It is still forecasting an increase (the blue line in the chart) – but by 0.7 of a percentage point less than it was forecasting a year ago (the pale green line): click here for a PowerPoint of the chart.

We have assumed that productivity growth will pick up a little, but remain significantly lower than its pre-crisis trend rate throughout the next five years. On average, we have revised trend productivity growth down by 0.7 percentage points a year. It now rises from 0.9 per cent this year to 1.2 per cent in 2022. This reduces potential output in 2021-22 by 3.0 per cent. The ONS estimates that output per hour is currently 21 per cent below an extrapolation of its pre-crisis trend. By the beginning of 2023 we expect this to have risen to 27 per cent.

Why has there been such weak productivity growth?
Weak productivity growth has been caused by a mixture of factors.

Perhaps the most important is that investment as a percentage of GDP has been lower than before the financial crisis and lower than in other countries. Partly this has been caused by a lack of funding for investment as banks have sought to rebuild their capital and have cut down on riskier loans. Partly it has been caused by a lack of demand for investment, given sluggish rates of economic growth and the belief that austerity will continue.

And it is not just private investment. Public-sector investment in transport infrastructure, housing and education and training has been lower than in other countries. Indeed, the poor training record and low skill levels in the UK are main contributors to low productivity.

The fall in the pound since the Brexit vote has raised business costs and further dampened demand as incomes have been squeezed.

Another reason for low productivity growth has been that employers have responded to weak demand, not by laying off workers and thereby raising unemployment, but by retaining low-productivity workers on low wages. Another has been the survival of ‘zombie’ firms, which, by paying low wages and facing ultra-low interest rates, are able to survive competition from firms that do invest.

Why is weak productivity growth forecast to continue?
Looking forward, the nature of the Brexit deal will impact on confidence, investment, wages and growth. If the deal is bad for the UK, the OBR’s forecasts are likely to be too optimistic. As it is, uncertainty over the nature of the post-Brexit world is weighing heavily on investment as some businesses choose to wait before committing to new investment.

On the other hand, exports may rise faster as firms respond to the depreciation of the pound and this may stimulate investment, thereby boosting productivity.

Another factor is the effect of continuing tight Budgets. There was some easing of austerity in this Budget, as the Chancellor accepted a slower reduction in the deficit, but government spending will remain tight and this is likely to weigh on growth and investment and hence productivity.

But this may all be too gloomy. It is very difficult to forecast productivity growth, especially as it is hard to measure output in much of the service sector. It may be that the productivity growth forecasts will be revised up before too long. For example, the benefits from new technologies, such as AI, may flow through more quickly than anticipated. But they may flow through more slowly and the productivity forecasts may have to be revised down even further!

The latest edition of the IMF’s Fiscal Monitor, ‘Tackling Inequality’ challenges conventional wisdom that policies to reduce inequality will also reduce economic growth.

While some inequality is inevitable in a market-based economic system, excessive inequality can erode social cohesion, lead to political polarization, and ultimately lower economic growth.

The IMF looks at three possible policy alternatives to reduce inequality without damaging economic growth

The first is a rise in personal income tax rates for top earners. Since top rates have been cut in most countries, with the OECD average falling from 62% to 35% over the past 30 years, the IMF maintains that there is considerable scope of raising top rates, with the optimum being around 44%. Evidence suggests that income tax elasticity is low at most countries’ current top rates, meaning that a rise in top income tax rates would only have a small disincentive effect on earnings.

An increased progressiveness of income tax should be backed by sufficient taxes on capital to prevent income being reclassified as capital. Different types of wealth tax, such as inheritance tax, could also be considered. Countries should also reduce the opportunities for tax evasion.

The second policy alternative is a universal basic income for all people. This could be achieved by various means, such as tax credits, child benefits and other cash benefits, or minimum wages plus benefits for the unemployed or non-employed.

The third is better access to health and education, both for their direct effect on reducing inequality and for improving productivity and hence people’s earning potential.

In all three cases, fiscal policy can help through a combination of taxes, benefits and public expenditure on social infrastructure and human capital.

But a major problem with using increased tax rates is international competition, especially with corporation tax rates. Countries are keen to attract international investment by having corporation tax rates lower than their rivals. But, of course, countries cannot all have a lower rate than each other. The attempt to do so simply leads to a general lowering of corporation tax rates (see chart in The Economist article) – to a race to the bottom. The Nash equilibrium rate of such a game is zero!
