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.

Is there a ‘magic money tree’? Is it desirable for central banks to create money to finance government deficits?
The standard thinking of conservative governments around the world is that creating money to finance deficits will be inflationary. Rather, governments should attempt to reduce deficits. This will reduce the problem of government expenditure crowding out private expenditure and reduce the burden placed on future generations of having to finance higher government debt.
If deficits rise because of government response to an emergency, such as supporting people and businesses during the Covid-19 pandemic, then, as soon as the problem begins to wane, governments should attempt to reduce the higher deficits by raising taxes or cutting government expenditure. This was the approach of many governments, including the Coalition and Conservative governments in the UK from 2010, as econommies began to recover from the 2007/8 financial crisis.
‘Modern Monetary Theory‘ challenges these arguments. Advocates of the theory support the use of higher deficits financed by monetary expansion if the money is spent on things that increase potential output as well as actual output. Examples include spending on R&D, education, infrastructure, health and housing.
Modern monetary theorists still accept that excess demand will lead to inflation. Governments should therefore avoid excessive deficits and central banks should avoid creating excessive amounts of money. But, they argue that inflation caused by excess demand has not been a problem for many years in most countries. Instead, we have a problem of too little investment and too little spending generally. There is plenty of scope, they maintain, for expanding demand. This, if carefully directed, can lead to productivity growth and an expansion of aggregate supply to match the rise in aggregate demand.
Government deficits, they argue, are not intrinsically bad. Government debt is someone else’s assets, whether in the form of government bonds, savings certificates, Treasury bills or other instruments. Provided the debt can be serviced at low interest rates, there is no problem for the government and the spending it generates can be managed to allow economies to function at near full capacity.

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.

The article below looks at the economy of Brazil. The statistics do not look good. Real output fell last year by 3.8% and this year it is expected to fall by another 3.3%. Inflation this year is expected to be 9.0% and unemployment 11.2%, with the government deficit expected to be 10.4% of GDP.
The article considers Keynesian economics in the light of the case of Brazil, which is suffering from declining potential supply, but excess demand. It compares Brazil with the case of most developed countries in the aftermath of the financial crisis. Here countries have suffered from a lack of demand, made worse by austerity policies, and only helped by expansionary monetary policy. But the effect of the monetary policy has generally been weak, as much of the extra money has been used to purchase assets rather than funding a growth in aggregate demand.
Different policy prescriptions are proposed in the article. For developed countries struggling to grow, the solution would seem to be expansionary fiscal policy, made easy to fund by lower interest rates. For Brazil, by contrast, the solution proposed is one of austerity. Fiscal policy should be tightened. As the article states:
Spending restraint might well prove painful for some members of Brazilian society. But hyperinflation and default are hardly a walk in the park for those struggling to get by. Generally speaking, austerity has been a misguided policy approach in recent years. But Brazil is a special case. For now, anyway.
The tight fiscal policies could be accompanied by supply-side policies aimed at reducing bureaucracy and inefficiency.

The ‘Classical’ Treasury view of the 1920s and 30s was that extra government spending or tax cuts were not the solution to depression and mass unemployment. Instead, it would crowd out private expenditure if the money supply were not allowed to rise as it would drive up interest rates. But if money supply were allowed to rise, this would be inflationary. The solution was to reduce budget deficits to increase confidence in public finances and to encourage private investment. Greater price and wage flexibility were the answer to markets not clearing.
Keynes countered these arguments by arguing that the economy could settle in a state of mass unemployment, with low confidence leading to lower consumer expenditure, lower investment, lower incomes and lower employment. The situation would be made worse, not better, by cuts in public expenditure or tax rises in an attempt to reduce the budget deficit. The solution was higher public expenditure to stimulate aggregate demand. This could be achieved by fiscal and monetary policies. Monetary policy alone could, however, be made ineffective by the liquidity trap. Extra money might simply be held rather than spent.
This old debate has been reborn since the financial crisis of 2007/8 and the subsequent deep recession and, more recently, the lack of recovery. (Click here for a PowerPoint of the chart.)
The articles below consider the current situation. Many economists, but certainly not all, take a Keynesian line that austerity policies to reduce public-sector deficits have been counter-productive. By dampening demand, such policies have reduced national income and slowed the recovery in both investment and consumer demand. This has at best slowed the rate of deficit reduction or at worst even increased the deficit, with lower GDP leading to a reduction in tax receipts and higher unemployment leading to higher government social security expenditure.
Although monetary policy has been very loose, measures such as record low interest rates and quantitative easing have been largely ineffective in stimulating demand. Economies are stuck in a liquidity trap, with banks preferring to build their reserves rather than to increase lending. This is the result partly of a lack of confidence and partly of pressure on them to meet Basel II and III requirements of reducing their leverage.
But despite the call from many economists to use fiscal policy and more radical monetary policy to stimulate demand, most governments have been pre-occupied with reducing their deficits and ultimately their debt. Their fear is that rising deficits undermine growth – a fear that was given weight by, amongst others, the work of Reinhart and Rogoff (see the blog posts Reinhart and Rogoff: debt and growth and It could be you and see also Light at the end of the tunnel – or an oncoming train?.
But there is some movement by governments. The new Japanese government under Shinzo Abe is following an aggressive monetary policy to drive down the exchange rate and boost aggregate demand (see A J-curve for Japan?) and, more recently, the European Commission has agreed to slow the pace of austerity by giving the Netherlands, France, Spain, Poland, Portugal and Slovenia more time to bring their budget deficits below the 3% of GDP target.
Of course, whether or not expansionary fiscal and/or monetary policies should be used to tackle a lack of growth does not alter the argument that supply-side policies are also required in order to increase potential economic growth.
