On 8 February, the Bank of England issued a statement that was seen by many as a warning for earlier and speedier than previously anticipated increases in the UK base rate. Mark Carney, the governor of the Bank of England, referred in his statement to ‘recent forecasts’ which make it more likely that ‘monetary policy would need to be tightened somewhat earlier and by a somewhat greater extent over the forecast period than anticipated at the time of the November report’.

A similar picture emerges on the other side of the Atlantic. With labour markets continuing to deliver spectacularly high rates of employment (the highest in the last 17 years), there are also now signs that wages are on an upward trajectory. According to a recent report from the US Bureau of Labor Statistics, US wage growth has been stronger than expected, with average hourly earnings rising by 2.9 percent – the strongest growth since 2009.

These statements have coincided with a week of sharp corrections and turbulence in the world’s largest capital markets, as investors become increasingly conscious of the threat of rising inflation – and the possibility of tighter monetary policy.

The Dow Jones plunged from an all-time high of 26,186 points on 1 February to 23,860 a week later – losing more than 10 per cent of its value in just five trading sessions (suffering a 4.62 percentag fall on 5 February alone – the worst one-day point fall since 2011). European and Asian markets followed suit, with the FTSE-100, DAX and NIKKEI all suffering heavy losses in excess of 5 per cent over the same period.

But why should higher inflationary expectations fuel a sell-off in global capital markets? After all, what firm wouldn’t like to sell its commodities at a higher price? Well, that’s not entirely true. Investors know that further increases in inflation are likely to be met by central banks hiking interest rates. This is because central banks are unlikely to be willing or able to allow inflation rates to rise much above their target levels.

The Bank of England, for instance, sets itself an inflation target of 2%. The actual ongoing rate of inflation reported in the latest quarterly Inflation Report is 3% (50 per cent higher than the target rate).

Any increase in interest rates is likely to have a direct impact on both the demand and the supply side of the economy.

Consumers (the demand side) would see their cost of borrowing increase. This could put pressure on households that have accumulated large amounts of debt since the beginning of the recession and could result in lower consumer spending.

Firms (the supply side) are just as likely to suffer higher borrowing costs, but also higher operational costs due to rising wages – both of which could put pressure on profit margins.

It now seems more likely that we are coming towards the end of the post-2008 era – a period that saw the cost of money being driven down to unprecedentedly low rates as the world’s largest economies dealt with the aftermath of the Great Recession.

For some, this is not all bad news – as it takes us a step closer towards a more historically ‘normal’ equilibrium. It remains to be seen how smooth such a transition will be and to what extent the high-leveraged world economy will manage to keep its current pace, despite the increasingly hawkish stance in monetary policy by the world’s biggest central banks.

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.

On 2 November, the Bank of England raised Bank rate from 0.25% to 0.5% – the first rise since July 2007. But was now the right time to raise interest rates? Seven of the nine-person Monetary Policy Committee voted to do so; two voted to keep Bank Rate at 0.25%.

Raising the rate, on first sight, may seem a surprising decision as growth remains sluggish. Indeed, the two MPC members who voted against the rise argued that wage growth was too weak to justify the rise. Also, inflation is likely to fall as the effects of the Brexit-vote-induced depreciation of sterling on prices feeds through the economy. In other words, prices are likely to settle at the new higher levels but will not carry on rising – at least not at the same rate.

So why did the other seven members vote to raise Bank Rate. There are three main arguments:

Inflation, at 3%, is above the target of 2% and is likely to stay above the target if interest rates are not raised.
There is little spare capacity in the economy, with low unemployment. There is no shortage of aggregate demand relative to output.
With productivity growth being negligible and persistently below that before the financial crisis, aggregate demand, although growing slower than in the past, is growing excessively relative to the growth in aggregate supply.

As the Governor stated at the press conference:

In many respects, the decision today is straightforward: with inflation high, slack disappearing, and the economy growing at rates above its speed limit, inflation is unlikely to return to the 2% target without some increase in interest rates.

But, of course, the MPC’s forecasts may turn out to be incorrect. Many things are hard to predict. These include: the outcomes of the Brexit negotiations; consumer and business confidence and their effects on consumption and investment; levels of growth in other countries and their effects on UK exports; and the effects of the higher interest rates on saving and borrowing and hence on aggregate demand.

The Bank of England is well aware of these uncertainties. Although it plans two more rises in the coming months and then Bank Rate remaining at 1% for some time, this is based on its current assessment of the outlook for the economy. If circumstances change, the Bank will adjust the timing and total amount of future interest rate changes.

There are, however, dangers in the rise in interest rates. Household debt is at very high levels and, although the cost of servicing these debts is relatively low, even a rise in interest rates of just 0.25 percentage points can represent a large percentage increase. For example, a rise in a typical variable mortgage interest rate from 4.25% to 4.5% represents a 5.9% increase. Any resulting decline in consumer spending could dent business confidence and reduce investment.

Nevertheless, the Bank estimates that the effect of higher mortgage rates is likely to be small, given that some 60% of mortgages are at fixed rates. However, people need to refinance such rates every two or three years and may also worry about the rises to come promised by the Bank.

  7. To what extent can the Bank of England’s monetary policy be described as ‘discretionary’?

In three interesting articles, linked below, the authors consider the state of economies since the financial crisis of 2007–8 and whether governments have the right tools to tackle future economic shocks.

There have been some successes over the past 10 years, in particular keeping inflation close to central bank targets despite considerable shocks (see the Vox article). Also unemployment has fallen in most countries and to very low levels in some, including the UK.

But economic growth has generally remained well below the levels prior to the financial crisis, with low productivity growth being the main culprit. Indeed, many people have seen no growth at all in their real incomes over the past 10 years, with low unemployment being bought at the cost of a growth in zero-hour contracts and work in the gig economy. And what economic growth we have seen has been largely the result of taking up slack through unprecedentedly loose monetary policy.

Fiscal policy, except in the period directly following the financial crisis, has generally been tight as governments have sought to reduce their deficits and slow down the growth in their debt.

But what will happen if economies once more slow? Or, worse still, what will happen if there is another global recession? Do countries have the policies to tackle the problem this time round?

Quantitative easing could be used again, but many economists believe that it will have more limited scope if confined to the purchase of assets in the secondary market. Also, there is little scope for reducing interest rates, which, despite some modest rises in the USA, remain at close to zero in most developed countries.

One possibility is a combination of monetary and fiscal policy, where new money is used to finance government expenditure on infrastructure, such as road and rail, broadband, green energy, hospitals and schools and colleges. This would avoid the need for governments to borrow on open markets as the spending would be financed by new government securities purchased directly by the central bank.

An objection to such ‘people’s quantitative easing‘, as it has been dubbed, is that it would effectively end the independence of central banks. This independence has been credited by many with giving central banks credibility in controlling inflation. Would inflationary expectations rise with people’s quantitative easing and, with it, actual inflation? A lot would depend on the extent to which this QE could still be conducted within a framework of targeting inflation and whether people’s expectations of inflation could be managed jointly by the government and central bank.

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!
