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!

We’ve considered Keynesian economics and policy in several blogs. For example, a year ago in the post, What would Keynes say?, we looked at two articles arguing for Keynesian expansionary polices. More recently, in the blogs, End of the era of liquidity traps? and A risky dose of Keynesianism at the heart of Trumponomics, we looked at whether Donald Trump’s proposed policies are more Keynesian than his predecessor’s and at the opportunities and risks of such policies.

The article below, Larry Elliott updates the story by asking what Keynes would recommend today if he were alive. It also links to two other articles which add to the story.

Elliott asks his imaginary Keynes, for his analysis of the financial crisis of 2008 and of what has happened since. Keynes, he argues, would explain the crisis in terms of excessive borrowing, both private and public, and asset price bubbles. The bubbles then burst and people cut back on spending to claw down their debts.

Keynes, says Elliott, would approve of the initial response to the crisis: expansionary monetary policy (both lower interest rates and then quantitative easing) backed up by expansionary fiscal policy in 2009. But expansionary fiscal policies were short lived. Instead, austerity fiscal policies were adopted in an attempt to reduce public-sector deficits and, ultimately, public-sector debt. This slowed down the recovery and meant that much of the monetary expansion went into inflating the prices of assets, such as housing and shares, rather than in financing higher investment.

He also asks his imaginary Keynes what he’d recommend as the way forward today. Keynes outlines three alternatives to the current austerity policies, each involving expansionary fiscal policy:

•  Trump’s policies of tax cuts combined with some increase in infrastructure spending. The problems with this are that there would be too little of the public infrastructure spending that the US economy needs and that the stimulus would be poorly focused.
•  Government taking advantage of exceptionally low interest rates to borrow to invest in infrastructure. “Governments could do this without alarming the markets, Keynes says, if they followed his teachings and borrowed solely to invest.”
•  Use money created through quantitative easing to finance public-sector investment in infrastructure and housing. “Building homes with QE makes sense; inflating house prices with QE does not.” (See the blogs, A flawed model of monetary policy and Global warning).

Increased government spending on infrastructure has been recommended by international organisations, such as the OECD and the IMF (see OECD goes public and The world economic outlook – as seen by the IMF). With the rise in populism and worries about low economic growth throughout much of the developed world, perhaps Keynesian fiscal policy will become more popular with governments.

In his 2016 Autumn Statement, the new Chancellor of the Exchequer, Philip Hammond, announced that he was abandoning his predecessor’s target of achieving a budget surplus in 2019/20 and beyond. This was partly in recognition that tax revenues were likely to be down as economic growth forecasts were downgraded by the Office for Budget Responsibility. But it was partly to give himself more room to boost the economy in response to lower economic growth. In other words, he was moving from a strictly rules-based fiscal policy to one that is more interventionist.

Although he still has the broad target of reducing government borrowing over the longer term, this new flexibility allowed him to announce increased government spending on infrastructure.

The new approach is outlined in the updated version of the Charter for Budget
, published alongside the Autumn Statement. The government’s fiscal mandate would now include the following:

 •  a target to reduce cyclically-adjusted public-sector net borrowing to below 2% of GDP by 2020/21;
 •  a target for public-sector net debt as a percentage of GDP to be falling in 2020/21.

It also states that:

In the event of a significant negative shock to the UK economy, the Treasury will review the appropriateness of the fiscal mandate and supplementary targets as a means of returning the public finances to balance as early as possible in the next Parliament.

In the Autumn Statement, the new approach to fiscal policy is summarised as follows:

This new fiscal framework ensures the public finances continue on the path to sustainability, while providing the flexibility needed to support the economy in the near term.

With his new found freedom, the Chancellor was able to announce spending increases, despite deteriorating public finances, of £36bn by 2021/22 (see Table 1 in the Autumn Statement).

Most of the additional expenditure will be on infrastructure. To facilitate this, the government will set up a new National Productivity Investment Fund (NPIF) to channel government spending to various infrastructure projects in the fields of housing, transport, telecoms and research and development. The NPIF will provide £23bn to such projects between 2017/18 and 2021/22.

But much of the additional flexibility in the new Fiscal Mandate will be to allow automatic fiscal stabilisers to operate. The OBR forecasts an increase in borrowing of £122bn over the 2017/18 to 2021/22 period compared with its forecasts made in March this year. Apart from the additional £23bn spending on infrastructure, most of the rest will be as a result of lower tax receipts from lower economic growth. This, in turn, is forecast to be the result of lower investment caused by Brexit uncertainties and lower real consumer spending because of the fall in the pound and the consequent rise in prices.

But rather than having to tighten fiscal policy to meet the previous borrowing target, the new Fiscal Mandate will permit this rise in borrowing. The lower tax payments will help to reduce the dampening effect on the economy.

So are we entering a new era of fiscal policy? Is the government now using discretionary fiscal policy to boost aggregate demand, while also attempting to increase productivity? Or is the relaxation of the Fiscal Mandate just a redrawing of the rules to give a bit more flexibility over the level of stimulus the government can give the economy?

  1. Distinguish between discretionary fiscal policy and rules-based fiscal policy.
  2. Why have forecasts of the public finances worsened since last March?
  3. What is meant by automatic fiscal stabilisers? How do they work when the economic growth slows?
  4. What determines the size of the multiplier from public-sector infrastructure projects?
  5. What dangers are there in relaxing the borrowing rules in the Fiscal Mandate?
  6. Examine the arguments for relaxing the borrowing rules more than they have been?
  7. If the economy slows more than has been forecast and public-sector borrowing rises faster, does the Chancellor have any more discretion in giving a further fiscal boost to the economy?
  8. Does the adjustment of borrowing targets as the economic situation changes make such a policy a discretionary one rather than a rules-based one?

As the Chancellor of the Exchequer, Philip Hammond, delivers his first Autumn statement, both the Office for Budget Responsibility (OBR) and the National Institute for Economic and Social Research (NIESR) have published updated forecasts for government borrowing and government debt.

They show a rise in government borrowing compared with previous forecasts. The main reason for this is a likely slowdown in the rate of economic growth and hence in tax revenues, especially in 2017. Last March, the OBR forecast GDP growth of 2.2% for 2017; it has now revised this down to 1.4%.

This forecast slowdown is because of a likely decline in the growth of aggregate demand caused by a decline in investment as businesses become more cautious given the uncertainty about the UK’s relationships with the rest of the world post Brexit. There is also likely to be a slowdown in real consumer expenditure as inflation rises following the fall in the pound of around 15%.

But what might be more surprising is that the public finances are not forecast to deteriorate even further. The OBR forecasts that the deficit will increase by a total of £122bn to £216bn over the period from 2016/17 to 2020/21. The NIESR predicts that it will rise by only £50bn to £187bn – but this is before the additional infrastructure spending and other measures announced in the Autumn Statement.

One reason is looser monetary policy. Following the Brexit vote, the Bank of England cut Bank Rate from 0.5% to 0.25% and introduced further quantitative easing. This makes it cheaper to finance government borrowing. What is more, the additional holdings of bonds by the Bank mean that the Bank returns to the government much of the interest (coupon payments) that would otherwise have been paid to the private sector.

Then, depending on the nature of the UK’s post-Brexit relationships with the EU, there could be savings in contributions to the EU budget – but just how much, no-one knows at this stage.

Finally, it depends on just what effects the measures announced in the Autumn Statement will have on tax revenues and government spending. We will examine this in a separate blog.

But even though public-sector borrowing is likely to fall more slowly than before the Brexit vote, the trajectory is still downward. Indeed, the previous Chancellor, George Osborne, had set a target of achieving a public-sector surplus by 2019/20.

But, would eventually bringing the public finances into surplus be desirable? Apart from the dampening effect on aggregate demand, such a policy could lead to underinvestment in infrastructure and other public-sector capital. There is thus a strong argument for continuing to run a deficit on the public-sector capital account to fund public-sector investment – such investment will increase incomes and social wellbeing in the future. It makes sense for the government to borrow for investment, just as it makes sense for the private sector to do so.

The Brexit vote has caused shockwaves throughout European economies. But there is a potentially larger economic and political problem facing the EU and the eurozone more specifically. And that is the state of the Italian banking system and the Italian economy.

Italy is the third largest economy in the eurozone after Germany and France. Any serious economic weaknesses could have profound consequences for the rest of the eurozone and beyond.

At 135% of GDP, Italy’s public-sector debt is one the highest in the world; its banks are undercapitalised with a high proportion of bad debt; and it is still struggling to recover from the crisis of 2008–9. The Economist article elaborates:

The adult employment rate is lower than in any EU country bar Greece. The economy has been moribund for years, suffocated by over-regulation and feeble productivity. Amid stagnation and deflation, Italy’s banks are in deep trouble, burdened by some €360 billion of souring loans, the equivalent of a fifth of the country’s GDP. Collectively they have provisioned for only 45% of that amount. At best, Italy’s weak banks will throttle the country’s growth; at worst, some will go bust.

Since 2007, the economy has shrunk by 10%. And potential output has fallen too, as firms have closed. Unemployment is over 11%, with youth unemployment around 40%.

Things seem to be coming to a head. As confidence in the Italian banking system plummets, the Italian government would like to bail out the banks to try to restore confidence and encourage deposits and lending. But under new eurozone rules designed to protect taxpayers, it requires that the first line of support should be from bondholders. Such support is known as a ‘bail-in’.

If bondholders were large institutional investors, this might not be such a problem, but a significant proportion of bank bonds in Italy are held by small investors, encouraged to do so by tax relief. Bailing in the banks by requiring bondholders to bear significant losses in the value of their bonds could undermine the savings of many Italians and cause them severe hardship, especially those who had saved for their retirement.

So what is the solution? Italian banks need recapitalising to restore confidence and prevent a more serious crisis. However, there is limited scope for bailing in, unless small investors can be protected. And eurozone rules provide little scope for government funding for the banks. These rules should be relaxed under extreme circumstances. At the same time, policy needs to focus on making Italian banking more efficient.

Meanwhile, the IMF is forecasting that Italian economic growth will be less than 1% this year and little better in 2017. Part of the problem, claims the IMF, is the Brexit vote. This has heightened financial market volatility and increasead the risks for Italy with its fragile banking system. But the problems of the Italian economy run deeper and will require various supply-side policies to tackle low productivity, corruption, public-sector inefficiency and a financial system not fit for purpose. What the mix of these policies should be – whether market based or interventionist – is not just a question of effectiveness, but of political viability and democratic support.
