Tag: output gap

The UK government has made much of its spending commitments in the UK Budget and Spending Review delivered on 27 October 2021. Spending on transport infrastructure, green energy and health care figured prominently. The government claimed that these were to help achieve its objectives of economic growth, carbon reduction and ‘levelling up’. This means that government expenditure will be around 42% of GDP for the five years from 2022 (from 1988 to 2000 it averaged 36%). Although it temporarily rose to 52% in 2020/21, this was the result of supporting the economy through the pandemic. But does this mean that the government is now a ‘Keynesian’ one?

When the economy is in recession, as was the case in 2020 with the effects of the pandemic, increased government expenditure financed by borrowing rather than taxation is the classic Keynesian remedy to boost aggregate demand and close the output gap. The increased injection of spending works through the multiplier process to raise equilibrium national income and reduce unemployment.

But is this the objective of the extra spending announced in October 2021? To answer this, it is important to look at forecasts for the state of the economy with no change in government policy and at the balance of government expenditure and taxation resulting from the Budget. The first chart shows public sector net borrowing from 2006/7 and forecast to 2026/7. The green and red lines from 2021/22 onwards give the PSNB forecasts with and without the October 2021 measures.

As you can see, there was a large increase in the PSNB in 2020/21, reflecting the government’s measures to support firms and workers during the pandemic. (Click here for a PowerPoint of the chart.) This was very much a Keynesian response, where a large budget deficit was necessary to support aggregate demand. It was also to protect the supply side of the economy by enabling firms to survive.

But could the October 2021 announcements also be seen as a Keynesian response to the macroeconomic situation? If we redraw Chart 1, focusing just on the forecast period and adjust the vertical scale, we can see that the measures have a net effect of increasing the PSNB and thus acting as a stimulus to aggregate demand. (Click here for a PowerPoint of the chart.) The figures are shown in the following table, which shows the totals from Table 5.1 in the Autumn Budget and Spending Review 2021 document:

Effects of Spending Review and Budget 2021 on PSNB (+ = increase in PSNB)

At first sight, it would seem that the Budget was mildly expansionary. To see how much so, the Office for Budget Responsibility (OBR) measures the ‘fiscal stance’ using the ‘cyclically adjusted primary deficit (CAPD)’. This is PSNB minus interest payments and minus expenditures and tax revenues that fluctuate with the cycle and which therefore act as automatic stabilisers. The OBR’s forecast of the CAPD shows it to be expansionary, but decreasing over time. In 2021/22, there is forecast to be a net injection of around 3.2% (excluding ‘virus-related’ support), falling to 2.7% in 2022/23 and then gradually to around 0.6% by 2026/27. So it does seem that fiscal policy remains expansionary throughout the period, but less and less so.

But this alone does not make it ‘Keynesian’. A Keynesian Budget would be one that uses fiscal policy to adjust aggregate demand (AD) according to whether AD is forecast to be deficient or excessive without the Budget measures. To operate a Keynesian Budget, it would be necessary to forecast the output gap without any policy measures. If was forecast to be negative (a deficiency of demand, with equilibrium output below the potential level), then an expansionary policy should be pursued by raising government expenditure, cutting taxes or some combination of the two. If it was forecast to be positive (an excess demand, with equilibrium output above the potential level), then a contractionary/deflationary policy should be pursued by cutting government expenditure, raising taxes or some combination of the two.

So what is the forecast for the output gap? The OBR states that, after being negative in 2020
(–0.4% of potential GDP), it has risen substantially to 0.9% in 2021 with the rapid bounce back from the pandemic. But it is forecast to remain positive, albeit declining, until reaching zero in 2025. This is illustrated in Chart 3. (Click here for a PowerPoint of the chart.) So fiscal policy remains mildly expansionary until 2025, after having provided a considerable stimulus in 2021.

This is not normally what a Keynesian economist would recommend. Fiscal policy should be designed to achieve a zero output gap. With the output gap being substantially positive in 2021, there is a problem of excess demand. This can be seen in supply-chain difficulties and labour shortages in certain areas and higher inflation, with CPI inflation predicted by the OBR to rise to 4.4 per cent in 2022. The combination of higher prices, the rise in national insurance from April 2022 by 1.25 percentage points and the freezing of income tax personal allowances will squeeze living standards. And the cancelling of the £20 per week uplift to Universal Credit and no increase in its rate for the unemployed will put particular pressure on some of the poorest people.

The government is hoping that the rise in government expenditure will have beneficial supply-side effects and increase potential national income. The aim is to create a high-wage, high-skilled, high-productivity economy though investment in innovation, infrastructure and skills. As the OBR states, ‘The rebounding economy has provided the Chancellor with a Budget windfall that he has added to with tax rises that lift the tax burden to its highest since the early 1950s’.

It remains to be seen whether the extra spending on education, training, infrastructure and R&D will be sufficient to achieve the long-term growth the Chancellor is seeking. The OBR is forecasting very modest growth into the longer term when the bounce back has worked through. Real GDP is forecast to grow on average by just 1.5% per year from 2024 to 2026. What is more, the OBR sees permanent scarring effects of around 2% of GDP from the pandemic and around 4% of GDP from Brexit.

The OECD has recently published its six-monthly Economic Outlook. This assesses the global economic situation and the prospects for the 38 members of the OECD.

It forecasts that the UK economy will bounce back strongly from the deep recession of 2020, when the economy contracted by 9.8 per cent. This contraction was deeper than in most countries, with the USA contracting by 3.5 per cent, Germany by 5.1 per cent, France by 8.2 per cent, Japan by 4.7 per cent and the OECD as a whole by 4.8 per cent. But, with the success of the vaccine roll-out, UK growth in 2021 is forecast by the OECD to be 7.2 per cent, which is higher than in most other countries. The USA is forecast to grow by 6.8 per cent, Germany by 3.3 per cent, France by 5.8 per cent, Japan by 2.6 per cent and the OECD as a whole by 5.3 per cent. Table 1 in the Statistical Annex gives the figures.

This good news for the UK, however, is tempered by some worrying features.

The OECD forecasts that potential economic growth will be negative in 2021, with capacity declining by 0.4 per cent. Only two other OECD countries, Italy and Greece, are forecast to have negative potential economic growth (see Table 24 in the Statistical Annex). A rapid increase in aggregate demand, accompanied by a decline in aggregate supply, could result in inflationary pressures, even if initially there is considerable slack in some parts of the economy.

Part of the reason for the supply constraints are the additional barriers to trade with the EU resulting from Brexit. The extra paperwork for exporters has added to export costs, and rules-of-origin regulations add tariffs to many exports to the EU (see the blog A free-trade deal? Not really). Another supply constraint linked to Brexit is the shortage of labour in certain sectors, such as hospitality, construction and transport. With many EU citizens having left the UK and not being replaced by equivalent numbers of new immigrants, the problem is likely to persist.

The scarring effects of the pandemic present another problem. There has been a decline in investment. Even if this is only temporary, it will have a long-term impact on capacity, unless there is a compensating rise in investment in the future. Many businesses have closed and will not re-open, including many High Street stores. Moves to working from home, even if partially reversed as the economy unlocks, will have effects on the public transport industry. Also, people may have found new patterns of consumption, such as making more things for themselves rather than buying them, which could affect many industries. It is too early to predict the extent of these scarring effects and how permanent they will be, but they could have a dampening effect on certain sectors.

Inflation

So will inflation take off, or will it remain subdued? At first sight it would seem that inflation is set to rise significantly. Annual CPI inflation rose from 0.7 per cent in March 2021 to 1.5 per cent in April, with the CPI rising by 0.6 per cent in April alone. What is more, the housing market has seen a large rise in demand, with annual house price inflation reaching 10.2 per cent in March.

But these rises have been driven by some one-off events. As the economy began unlocking, so spending rose dramatically. While this may continue for a few months, it may not persist, as an initial rise in household spending may reflect pent-up demand and as the furlough scheme comes to an end in September.

As far as as the housing market is concerned, the rise in demand has been fuelled by the stamp duty ‘holiday’ which exempts residential property purchase from Stamp Duty Land Tax for properties under £500 000 in England and Northern Ireland and £250 000 in Scotland and Wales (rather than the original £125 000 in England and Northern Ireland, £145 000 in Scotland and £180 000 in Wales). In England and Northern Ireland, this limit is due to reduce to £250 000 on 30 June and back to £125 000 on 30 September. In Scotland the holiday ended on 31 March and in Wales is due to end on 30 June. As these deadlines are passed, this should see a significant cooling of demand.

Finally, although the gap between potential and actual output is narrowing, there is still a gap. According to the OECD (Table 12) the output gap in 2021 is forecast to be −4.6 per cent. Although it was −11.4 per cent in 2020, a gap of −4.6 per cent still represents a significant degree of slack in the economy.

At the current point in time, therefore, the Bank of England does not expect to have to raise interest rates in the immediate future. But it stands ready to do so if inflation does show signs of taking off.

On 10 March, the House of Representatives gave final approval to President Biden’s $1.9tr fiscal stimulus plan (the American Rescue Plan). Worth over 9% of GDP, this represents the third stage of an unparalleled boost to the US economy. In March 2020, President Trump secured congressional agreement for a $2.2tr package (the CARES Act). Then in December 2020, a bipartisan COVID relief bill, worth $902bn, was passed by Congress.

By comparison, the Obama package in 2009 in response to the impending recession following the financial crisis was $831bn (5.7% of GDP).

The American Rescue Plan

The Biden stimulus programme consists of a range of measures, the majority of which provide monetary support to individuals. These include a payment of $1400 per person for single people earning less than $75 000 and couples less than $150 000. These come on top of payments of $1200 in March 2020 and $600 in late December. In addition, the top-up to unemployment benefits of $300 per week agreed in December will now continue until September. Also, annual child tax credit will rise from $2000 annually to as much as $3600 and this benefit will be available in advance.

Other measures include $350bn in grants for local governments depending on their levels of unemployment and other needs; $50bn to improve COVID testing centres and $20bn to develop a national vaccination campaign; $170bn to schools and universities to help them reopen after lockdown; and grants to small businesses and specific grants to hard-hit sectors, such as hospitality, airlines, airports and rail companies.

Despite supporting the two earlier packages, no Republican representative or senator backed this latest package, arguing that it was not sufficiently focused. As a result, reaction to the package has been very much along partisan lines. Nevertheless, it is supported by some 90% of Democrat voters and 50% of Republican voters.

Is the stimulus the right amount?

Although the latest package is worth $1.9tr, aggregate demand will not expand by this amount, which will limit the size of the multiplier effect. The reason is that the benefits multiplier is less than the government expenditure multiplier as some of the extra money people receive will be saved or used to reduce debts.

With $3tr representing some 9% of GDP, this should easily fill the estimated negative output gap of between 2% and 3%, especially when multiplier effects are included. Also, with savings having increased during the recession to put them some 7% above normal, the additional amount saved may be quite small, and wealthier Americans may begin to reduce their savings and spend a larger proportion of their income.

So the problem might be one of excessive stimulus, which in normal times could result in crowding out by driving up interest rates and dampening investment. However, the Fed is still engaged in a programme of quantitative easing. Between mid-March 2020 and the end of March 2021, the Fed’s portfolio of securities held outright grew from $3.9tr to $7.2tr. What is more, many economists predict that inflation is unlikely to rise other than very slightly. If this is so, it should allow the package to be financed easily. Debt should not rise to unsustainable levels.

Other economists argue, however, that inflationary expectations are rising, reflected in bond yields, and this could drive actual inflation and force the Fed into the awkward dilemma of either raising interest rates, which could have a significant dampening effect, or further increasing money supply, potentially leading to greater inflationary problems in the future.

A lot will depend what happens to potential GDP. Will it rise over the medium term so that additional spending can be accommodated? If the rise in spending encourages an increase in investment, this should increase potential GDP. This will depend on business confidence, which may be boosted by the package or may be dampened by worries about inflation.

Additional packages to come

Potential GDP should also be boosted by two further packages that Biden plans to put to Congress.

The first is a $2.2tr infrastructure investment plan, known as the American Jobs Plan. This is a 10-year plan to invest public money in transport infrastructure (such as rebuilding 20 000 miles of road and repairing bridges), public transport, electric vehicles, green housing, schools, water supply, green power generation, modernising the power grid, broadband, R&D in fields such as AI, social care, job training and manufacturing. This will be largely funded through tax increases, such as gradually raising corporation tax from 21% to 28% (it had been cut from 35% to 21% by President Trump) and taxing global profits of US multinationals. However, the spending will generally precede the increased revenues and thus will raise aggregate demand in the initial years. Only after 15 years are revenues expected to exceed costs.

The second is a yet-to-be announced plan to increase spending on childcare, healthcare and education. This should be worth at least $1tr. This will probably be funded by tax increases on income, capital gains and property, aimed largely at wealthy individuals. Again, it is hoped that this will boost potential GDP, in this case by increasing labour productivity.

With earlier packages, the total increase in public spending will be over $8tr. This is discretionary fiscal policy writ large.

On 25 November, the UK government published its Spending Review 2020. This gives details of estimated government expenditure for the current financial year, 2020/21, and plans for government expenditure and the likely totals for 2021/22.

The focus of the Review is specifically on the effects of and responses to the coronavirus pandemic. It does not consider the effects of Brexit, with or without a trade deal, or plans for taxation. The Review is based on forecasts by the Office for Budget Responsibility (OBR). Because of the high degree of uncertainty over the spread of the disease and the timing and efficacy of vaccines, the OBR gives three forecast values for most variables – pessimistic, central and optimistic.

According to the central forecast, real GDP is set to decline by 11.3% in 2020, the largest one-year fall since the Great Frost of 1709. The economy is then set to ‘bounce back’ (somewhat), with GDP rising by 5.2% in 2021.

Unemployment will rise from 3.9% in 2019 to a peak of 7.5% in mid-2021, after the furlough scheme and other support for employers is withdrawn.

This blog focuses at the impact on government borrowing and debt and the implications for the future – both the funding of the debt and ways of reducing it.

Soaring government deficits and debt


Government expenditure during the pandemic has risen sharply through measures such as the furlough scheme, the Self-Employment Income Support Scheme and various business loans. This, combined with falling tax revenue, as incomes and consumer expenditure have declined, has led to a rise in public-sector net borrowing (PSNB) from 2.5% of GDP in 2019/20 to a central forecast of 19% for 2020/21 – the largest since World War II. By 2025/26 it is still forecast to be 3.9% of GDP. The figure has also been pushed up by a fall in nominal GDP for 2020/21 (the denominator) by nearly 7%. (Click here for a PowerPoint of the above chart.)

The high levels of PSNB are pushing up public-sector net debt (PSNB). This is forecast to rise from 85.5% of GDP in 2019/20 to 105.2% in 2020/21, peaking at 109.4% in 2023/24.

The exceptionally high deficit and debt levels will mean that the government misses by a very large margin its three borrowing and debt targets set out in the latest (Autumn 2016) ‘Charter for Budget Responsibility‘. These are:

  • to reduce cyclically-adjusted public-sector net borrowing to below 2% of GDP by 2020/21;
  • for public-sector net debt as a percentage of GDP to be falling in 2020/21;
  • for overall borrowing to be zero or in surplus by 2025/26.

But, as the Chancellor said in presenting the Review:

Our health emergency is not yet over. And our economic emergency has only just begun. So our immediate priority is to protect people’s lives and livelihoods.

Putting the public finances on a sustainable footing

Running a large budget deficit in an emergency is an essential policy for dealing with the massive decline in aggregate demand and for supporting those who have, or otherwise would have, lost their jobs. But what of the longer-term implications? What are the options for dealing with the high levels of debt?

1. Raising taxes. This tends to be the preferred approach of those on the left, who want to protect or improve public services. For them, the use of higher progressive taxes, such as income tax, or corporation tax or capital gains tax, are a means of funding such services and of providing support for those on lower incomes. There has been much discussion of the possibility of finding a way of taxing large tech companies, which are able to avoid taxes by declaring very low profits by diverting them to tax havens.

2. Cutting government expenditure. This is the traditional preference of those on the right, who prefer to cut the overall size of the state and thus allow for lower taxes. However, this is difficult to do without cutting vital services. Indeed, there is pressure to have higher government expenditure over the longer term to finance infrastructure investment – something supported by the Conservative government.

A downside of either of the above is that they squeeze aggregate demand and hence may slow the recovery. There was much discussion after the financial crisis over whether ‘austerity policies’ hindered the recovery and whether they created negative supply-side effects by dampening investment.

3. Accepting higher levels of debt into the longer term. This is a possible response as long as interest rates remain at record low levels. With depressed demand, loose monetary policy may be sustainable over a number of years. Quantitative easing depresses bond yields and makes it cheaper for governments to finance borrowing. Servicing high levels of debt may be quite affordable.

The problem is if inflation begins to rise. Even with lower aggregate demand, if aggregate supply has fallen faster because of bankruptcies and lack of investment, there may be upward pressure on prices. The Bank of England may have to raise interest rates, making it more expensive for the government to service its debts.

Another problem with not reducing the debt is that if another emergency occurs in the future, there will be less scope for further borrowing to support the economy.

4. Higher growth ‘deals’ with the deficit and reduces debt. In this scenario, austerity would be unnecessary. This is the ‘golden’ scenario – for the country to grow its way out of the problem. Higher output and incomes leads to higher tax revenues, and lower unemployment leads to lower expenditure on unemployment benefits. The crucial question is the relationship between aggregate demand and supply. For growth to be sustainable and shrink the debt/GDP ratio, aggregate demand must expand steadily in line with the growth in aggregate supply. The faster aggregate supply can grow, the faster can aggregate demand. In other words, the faster the growth in potential GDP, the faster can be the sustainable rate of growth of actual GDP and the faster can the debt/GDP ratio shrink.

One of the key issues is the degree of economic ‘scarring’ from the pandemic and the associated restrictions on economic activity. The bigger the decline in potential output from the closure of firms and the greater the deskilling of workers who have been laid off, the harder it will be for the economy to recover and the longer high deficits are likely to persist.

Another issue is the lack of labour productivity growth in the UK in recent years. If labour productivity does not increase, this will severely restrict the growth in potential output. Focusing on training and examining incentives, work practices and pay structures are necessary if productivity is to rise significantly. So too is finding ways to encourage firms to increase investment in new technologies.

With promises by the newly elected Conservative government to increase investment expenditure on health, education, innovation and infrastructure, it was expected that Rishi Sunak’s first Budget would be strongly expansionary. In fact, it turned out to be two Budgets in one – both giving a massive fiscal boost.

An emergency Budget

The first part of the Budget was a short-term emergency response to the explosive spread of the coronavirus. An extra £12 billion is to be spent on the NHS and other public services. Whether this will be anything like enough to cope with the effects of the pandemic as businesses fail and people lose their jobs remains to be seen. (See the blog A global supply-side shock: the impact of the coronavirus (COVID-19) outbreak.)

A key issue is just how quickly the money can be spent. How quickly can you train health professionals or produce more ventilators or provide extra hospital beds?

This emergency part of the Budget was co-ordinated with the Bank of England’s decision to cut Bank Rate from 0.75% to 0.25%.

This combined fiscal and monetary response to the crisis was further enhanced by the agreement of central banks on 15 March to boost world liquidity by increasing the supply of US dollars through large-scale quantitative easing. The US central bank, the Federal Reserve, also cut its main federal funds rate by one percentage point from 1–1.25% to 0–0.25%.

The planned Budget

The second part of the Budget is to raise government investment by 9% in real terms over the next four years, bringing overall government expenditure to 41% of GDP, financed largely by extra borrowing. As the IFS observes, “That is above its pre-crisis level and bigger than at any point between the mid 1980s and the start of the financial crisis.”

But despite this rise in the proportion of government spending to GDP, in other respects the spending plans are less expansionary than they may appear. Increases in current spending on health, education and defence had already been promised. This leaves other departments, such as social security, facing cuts, or at least no increase. And when compared with 2010/11 levels, if you exclude health, government current spending per head of the population will around 14% lower, or 19% lower once you account for spending that replaces EU funding.

The Chancellor’s hope is that, by focusing on investment, there will be a supply-side effect as well as a demand-side boost. If increases in aggregate demand are balanced by increases in aggregate supply, such a policy would not be inflationary in the long run. But in the light of the considerable uncertainty of the effects of the coronavirus, the plans may well require significant adjustment in the Autumn Budget – or earlier.
