To make a sensible comparison of one year’s national income generated from the production of goods and services with another we need to take inflation into account. Changes in inflation-adjusted GDP represent changes in the volume of production of a country’s goods and services: in other words, the real value of goods and services. We revisit the blog written back in April 2019, prior the pandemic, to show how changes in real GDP evidence what we may refer to as the twin characteristics of economic growth: positive long-term growth but with fluctuating short-term rates of growth.

Real and nominal GDP

The nominal or current-price estimate for UK Gross Domestic Product in 2020 is £2.156 trillion. It is the value of output produced within the country in 2020. This was a fall of 4.4 per cent on the £2.255 trillion recorded in 2019. These values make no adjustment for inflation and therefore reflect the prices of output that were prevailing at the time.

Chart 1 shows current-price estimates of GDP from 1950 when the value of GDP was estimated at £12.7 billion. The increase to £2.156 trillion in 2020 amounts to a proportionate increase of almost 170 times, a figure that rises to 211 times if we compare the 1950 value with the latest IMF estimate for 2025 of £2.689 trillion. However, if we want to make a more meaningful comparison of the country’s national income by looking at the longer-term increase in the volume of production, we need to adjust for inflation.

Long-term growth in real GDP

If we measure GDP at constant prices, we eliminate the effect of inflation. To construct a constant-price series for GDP a process known as chain-linking is used. This involves taking consecutive pairs of years, e.g. 2020 and 2021, and estimating what GDP would be in the most recent year (in this case, 2021) if the previous year’s prices (i.e. 2020) had continued to prevail. By calculating the percentage change from the previous year’s GDP value we have an estimate of the volume change. If this is repeated for other pairs of years, we have a series of percentage changes that capture the volume changes from year-to-year. Finally, a reference year is chosen and the percentage changes are applied backwards and forwards from the nominal GDP value for the reference year – the volume changes forwards and backwards from this point.

In effect, a real GDP series creates a quantity measure in monetary terms. Chart 1 shows GDP at constant 2019 prices (real GDP) alongside GDP at current prices (nominal GDP). Consider first the real GDP numbers for 1950 and 2020. GDP in 1950 at 2019 prices was £410.1 billion. This is higher than the current-price value because prices in 2019 (the reference year) were higher than those in 1950. Meanwhile, GDP in 2020 when measured at 2019 prices was £2.037 trillion. This constant-price value is smaller than the corresponding current-price value because prices in 2019 where lower than those in 2020.

Between 1950 and 2020 real GDP increased 5.0 times. If we extend the period to 2025, again using the latest IMF estimates, the increase is 5.9 times. Because we have removed the effect of inflation, the real growth figure is much lower than the nominal growth figure. Crucially, what we are left with is an indicator of the long-term growth in the volume of the economy’s output and hence an increase in national income that is backed up by an increase in production. Whereas nominal growth rates are affected both by changes in volumes and prices, real growth rates reflect only changes in volumes.

The upward trajectory observed in constant-price GDP is therefore evidence of positive longer-term growth. This is one of the twin characteristics of growth.

Short-term fluctuations in the growth of real GDP

The second characteristic is fluctuations in the rate of growth from period to period. We can see this second characteristic more clearly by plotting the percentage change in real GDP from year to year.

Chart 2 shows the annual rate of growth in real GDP each year since 1950. From it, we see the inherent instability that is a key characteristic of the macroeconomic environment. This instability is, of course, mirrored in the output path of real GDP in Chart 1, but the annual rates of growth show the instability more clearly. We can readily see the impact on national output of the global financial crisis and the global health emergency.

In 2009, constant-price GDP in the UK fell by 4.25 per cent. Then, in 2020, constant-price GDP and, hence, the volume of national output fell by 9.7 per cent, as compared to a 4.4 per cent fall in current-price GDP that we identified earlier. These global, ‘once-in-a-generation’ shocks are stark examples of the instability that characterises economies and which generate the ‘ups and downs’ in an economy’s output path, known more simply as ‘the business cycle’. (Click here to download a PowerPoint copy of the chart.)

Determinants of long-and short-term growth

The twin characteristics of growth can be seen simultaneously by combining the output path captured by the levels of real GDP with the annual rates of growth. This is shown in Chart 3. The longer-term growth seen in the economy’s output path is generally argued to be driven by the quantity and quality of the economy’s resources, and their effectiveness when combined in production. In other words, it is the supply-side that determines the trajectory of the output path over the longer term. (Click here to download a PowerPoint copy of the chart.)

However, the fluctuations we observe in short-term growth rates tend to reflect impulses that affect the ability and or willingness of producers to supply (supply-side shocks) and purchasers to consume (demand-side shocks). These impulses are then propagated and their effects, therefore, transmitted through the economy.

Effects of the pandemic

The pandemic is unusual in that the health intervention measures employed by governments around the world resulted in simultaneous negative aggregate demand and aggregate supply shocks. Economists were particularly concerned that the magnitude of these impulses and their propagation had the potential to generate scarring effects and hence negative hysteresis effects. The concern was that these would affect the level of real GDP in the medium-to-longer term and, hence, the vertical position of the output path, as well as the longer-term rate of growth and, hence, the steepness of the output path.

The extent of these scarring effects continues to be debated. The ability of businesses and workers to adapt their practices, the extraordinary fiscal and monetary measures that were undertaken in many countries, and the roll-out of vaccines programmes, especially in advanced economies, have helped to mitigate some of these effects. For example, the latest IMF forecasts for output in the USA in 2024 are over 2 per cent higher than those made back in October 2019.

Scarring effects are, however, thought to be an ongoing issue in the UK. The IMF is now expecting output in the UK to be nearly 3 per cent lower than it originally forecast back in October 2019. Therefore, whilst UK output is set to recover, scarring effects on the UK economy will mean that the output path traced out by real GDP will remain, at least in the medium term, vertically lower than was expected before the pandemic.

The COVID-19 pandemic had a stark effect on countries’ public finances. Governments had to make difficult fiscal choices around spending and taxation to safeguard public health, and the protection of jobs and incomes both in the present and in the future. The fiscal choices were to have historically large effects on the size of public spending and on the size of public borrowing. Here we briefly summarise the magnitude of these effects on public spending, receipts and borrowing in the UK.

The public sector comprises both national government and local or regional government. In financial year 2019/20 public spending in the UK was £886 billion. This would rise to £1.045 trillion in 2020/21. To understand better the magnitude of these figures we can express them as a share of national income (Gross Domestic Product). In 2019/20 public spending was 39.8 per cent of national income. This rose to 52.1 per cent in 2020/21. Meanwhile, public-sector receipts, largely taxation, fell from £829.1 billion in 2019/20 to £796.5 billion in 2020/21, though, because of the fall in national income, the share of receipts in national income rose very slightly from 37.3 to 37.9 per cent of national income.

The chart shows both public spending and public receipts as a share of national income since 1900. (Click here for a PowerPoint of the chart.) What this chart shows is the extraordinary impact of the two World Wars on the relative size of public spending. We can also see an uptick in public spending following the global financial crisis and, of course, the COVID-19 pandemic. The chart also shows that spending is typically larger than receipts meaning that the public sector typically runs a budget deficit. .
If we focus on public spending as a share of national income and its level following the two world wars, we can see that it did not fall back to pre-war levels. This is what Peacock and Wiseman (1961) famously referred to as a displacement effect. They attributed this to, among other things, an increase in the public’s tolerance to pay higher taxation because of the higher taxes levied during the war as well as to a desire for greater public intervention. The latter arose from an inspection effect. This can be thought of as a public consciousness effect, with the war helping to shine a light on a range of economic and social issues, such as health, housing and social security. These two effects, it is argued, reinforced each other, allowing the burden of taxation to rise and, hence, public spending to increase relative to national income.

If we forward to the global financial crisis, we can again see public spending rise as a share of national income. However, this time the ratio did not remain above pre-crisis levels. Rather, the UK government was fearful of unsustainable borrowing levels and the crowding out of private-sector activity by the public sector, with higher interest rates making public debt an attractive proposition for investors. It thus sought to reduce the public-sector deficit by engaging in what became known as ‘austerity’ measures.

If we move forward further to the COVID-19 pandemic, we see an even more significant spike in public spending as a share of national income. It is of course rather early to make predictions about whether the pandemic will have enduring effects on public spending and taxation. Nonetheless the pandemic, in a similar way to the two world wars, has sparked public debates on many economic and social issues. Whilst debates around the funding of health and social care are longstanding, it could be argued that the pandemic has provided the government with the opportunity to introduce the 1.25 percentage point levy from April 2022 on the earned incomes of workers (both employees and the self-employed) and on employers. (See John’s blog Fair care? for a fuller discussion on the tax changes to pay for increased health and social care expenditure).

The extent to which there may be a pandemic displacement effect will depend on the fiscal choices made in the months and years ahead. The key question is how powerful will be the effect of social issues like income and wealth inequality, regional and inter-generational disparities, discrimination, poor infrastructure and educational opportunities in shaping these fiscal choices? Will these considerations carry more weight than the push to consolidate the public finances and tighten the public purse? These fiscal choices will determine the extent of any displacement effect in public spending and taxation.

In March 2020, the UK government introduced a Coronavirus Job Retention Scheme. Businesses that had to close or cut back could put staff on furlough and the scheme would allow employers to claim 80% of workers’ wages up to £2500 per month. This would be passed on to workers.

There was large-scale uptake of the scheme. By the end of August, 9.6 million employees were on furlough (28% of the workforce) from around 1.2 million employers (61% of eligible employers). The scheme significantly stemmed the rise in unemployment. The claimant count rose 121% from March to August from 1.24 million to 2.74 million, far less than it would have done without the furlough scheme.

Since 1 August the level of support has been reduced in stages and is due to end on 31 October. It will then be replaced by a new ‘Job Support Scheme (JSS)‘ running from 1 November 2020 to 30 April 2021. Initially, employees must work at least 33% of their usual hours. For hours not worked, the government and the employer will pay a third each. There would be no pay for the final third. This means that an employee would receive at least 77.7% (33% + (2/3)67%) of their full pay – not far short of the 80% under the furlough scheme.

Effects on unemployment

Will the scheme see a substantial rise in unemployment, or will it be enough to support a gradual recovery in the economy as more businesses are able to reopen or take on more staff?

On first sight, it might seem that the scheme will give only slightly less job protection than the job furlough scheme with employees receiving only a little less than before. But, unlike the previous scheme, employers will have to pay not only for work done, but also an additional one-third for work not done. This is likely to encourage employers to lay off part of their staff and employ the remainder for more than one-third of their usual hours. Other firms may simply not engage with the scheme.

What is more, the furlough scheme paid wages for those previously employed by firms that were now closed. Under the new scheme, employees of firms that are forced to stay closed, such as many in the entertainments industry, will receive nothing. They will lose their jobs (at least until such firms are able to reopen) and will thus probably have to look for a new job. The scheme does not support them.

The government acknowledges that some people will lose their jobs but argues that it should not support jobs that are no longer viable. The question here is whether some jobs will eventually become viable again when the Covid restrictions are lifted.

With Covid cases on the rise again and more restrictions being imposed, especially at a local level, it seems inevitable that unemployment will continue to rise for some time with the ending of the furlough scheme and as the demand for labour remains subdued. The ending of the new scheme in April could compound the problem. Even when unemployment does begin to fall, it may take many months to return to pre-pandemic levels.

Update: expansion of the scheme

On 9 October, with Covid-19 cases rising rapidly in some parts of the country and tighter restrictions being imposed, the government announced that it was extending the scheme. From 1 November, employees of firms in certain parts of the country that would be required to close by the government, such as bars and restaurants, would be paid two-thirds of their previous wages by the government.

Critics of this extension to the scheme argue many firms will still be forced to shut because of lack of demand, even though they are not legally being required close. Employees of such firms will receive nothing from the scheme and will be forced onto Universal Credit. Also, the scheme will mean that many of the workers who do receive the money from the government will still face considerable hardship. Many will previously have been on minimum wages and thus will struggle to manage on only two-thirds of their previous wages.

In a little over a decade economies around the world have experienced two ‘once-in-a-lifetime’ shocks. First, there was the global financial crisis of the late 2000s, which saw an unsustainable expansion of banks’ balance sheets that resulted in a global economic slowdown. Now in 2020, a global health emergency has meant unprecedented falls in economic activity. In both cases, the public sector has been the economy’s shock absorber but this has had dramatic effects on its financial wellbeing. We consider here the effect on the UK public finances and reflect on their sustainability in light of the recent Fiscal Sustainability Report published by the Office of Budget Responsibility (OBR).

The COVID-19 pandemic saw the government initiate a range of fiscal interventions to support people and businesses. Interventions directly affecting public-sector spending included a series of employment support measures. These included the Coronavirus Job Retention Scheme, commonly referred to as the furlough scheme, the Self-employed Income Support scheme, a ‘Kickstart Scheme’ of work placements for universal credit recipients aged between 16 and 24 and a ‘Job Retention Bonus’ whereby employers can receive a one-off payment of £1,000 for every furloughed employee continuously employed from the cessation of the Job Retention Scheme on 31 October through to 31 January 2021.

Further spending interventions have included small business grant schemes, such as the Coronavirus Small Business Grant Fund, the coronavirus Retail, Hospitality and Leisure Grant Fund and the Coronavirus Local Authority Discretionary Grants Fund.

Meanwhile, taxation relief measures have included a business rates holiday for retail, hospitality and leisure businesses and a reduced rate of VAT of 5 per cent for hospitality, accommodation and attractions until 12 January 2021.

OBR’s central scenario

The OBR in its Fiscal Stability Report in July 2020 attempts to assess the wellbeing of the public finances not just in the short term but in the medium and longer term too. This longer-term perspective allows it to assess the sustainability of the public finances.

Its analysis is based on some key assumptions, including population growth and future demands on public services, but, understandably, the timing of this report has necessitated some key assumptions around path of the economy, including the extent to which the economy will experience scarring effects, also known as hysteresis effects. While the analysis does not incorporate the Chancellor’s measures announced in its summer statement on the 8 July, including the kickstart scheme, job retention bonus and the reduced rate of VAT, which would have a material effect on this year’s numbers, the OBR concludes that there would be less significant impact on its medium-term analysis.

In what it describes as its ‘central scenario’ the OBR forecasts that national output (real GDP) will fall by 12 per cent in 2020 before growing by 9 per cent in 2021 and 4 per cent in 2022. National output therefore reaches its pre-virus peak at the end of 2022. However, 20 quarters on from the pandemic shock in Q1 2020 output is estimated to be 3.2 per cent less than it would otherwise have been, while the cumulative loss of output is expected to be 6.4 per cent over the period. The cumulative loss of output in the 20 quarters following the financial crisis (Q2 2008) is estimated to have been 9.3 per cent of actual cumulative output.

While national output is expected to be permanently lower because of the pandemic, consistent with hysteresis, the forecast assumes that the longer-term growth rate is unaffected. In other words, there is not expected to be what some now refer to as ‘super hysteresis’, whereby the scarring effects have persistent effects on rates of capital accumulation, innovation and productivity, which therefore depress structural economic growth rates.

Meanwhile, the unemployment rate is expected to peak at 11.9 per cent in the final quarter of this year, before falling to 8.8 per cent in Q4 2021 and 6.3 per cent in Q4 2022. By Q4 2025 the unemployment rate is forecast to be 5.1 per cent, one percentage point higher than the OBR was forecasting at the time of the Budget in March.

Spending and receipts

Chart 1 shows shows the predicted paths of (nominal) public-sector receipts and expenditures as a percentage of (nominal) GDP. Receipts are expected come in at £740 billion this financial year (excluding the impact of the summer statement measures), some £133 billion lower than was forecast at the time of the March budget. This will amount to a 10 per cent fall in receipts in the financial year, driven by a much-shrunken economy. However, the fact that nominal GDP falls somewhat more means that the receipts-to-GDP ratio ticks up slightly. (Click here for a PowerPoint of the chart.)

Public-sector spending is expected to be higher in 2020/21 than was forecast in the March by £135 million (excluding the summer statement measures) reflecting the COVID-19 interventions. This would result in spending rising to £1.06 trillion, a 20 per cent rise in the financial year. It would also mean that public-sector spending as a share of GDP rises to 54 per cent – its highest since 1945/46.

Going forward, in cash terms receipts are permanently lower than forecast because GDP is lower, though as a share of GDP cash receipts increase very slightly, but remain below what was expected at the time of the March budget. Spending in cash terms is expected to fall back by close to 8 per cent next financial year before increasing by 3 per cent per year up to 2024/25. This means that the spending-to-GDP ratio falls back to around 43 per cent by 2024/25, a couple of percentage points higher than was forecast back in March.

Deficits and debt

The difference between spending and receipts is known as public-sector net borrowing. While the extent of borrowing can be inferred by inspection of Chart 1, it can be seen more readily in Chart 2 which plots the path of public-sector net borrowing as a share of GDP.

The OBR is now forecasting a budget deficit of £322 billion (excluding the summer statement measures) in 2020/21 compared to £55 billion at the time of the March Budget. This would be equivalent to over 16 per cent of GDP, the highest since the Second World War. In a follow-up presentation on the Fiscal Stability Report on the 14 July the OBR suggested that the inclusion of summer statement measures could mean the deficit being as high as £375 billion, implying a deficit-to-GDP ratio of just shy of 19 per cent. (Click here for a PowerPoint of the chart.)

Deficits represent borrowing and are therefore a flow concept. The accumulated deficits over the years (minus any surpluses) gives total debt, which is a stock concept. The public-sector’s net debt is its gross debt less its liquid assets, principally deposits held with financial institutions and holdings of international reserves. This is also affected by Bank of England interventions, such as the Term Funding Scheme which enables banks and building societies to borrow funds at close to Bank Rate for up to four years. Nonetheless, the key driver of net debt-to-GDP ratio going forward is the persistence of deficits.

Chart 3 shows the expected path of the net debt-to-GDP ratio. The OBR expects this to exceed 100 per cent in 2020/21 for the first time since 1960/61. This reflects an increase in cash terms of the stock of net debt to £2.2 trillion, up from £1.8 trillion at the end of 2019/20, as well as a fall in GDP. By 2024/25 the net debt stock is expected to have risen to £2.6 trillion, £600 billion more than expected at the time of the March budget, with the net debt-to-GDP ratio still above 100 per cent at 102.1 per cent. (Click herefor a PowerPoint of the chart.)

Sustainability

The higher debt-to-GDP ratio raises longer-term questions about the sustainability of the public finances. The government is currently reviewing its fiscal rules and is expected to report back in time for the autumn budget. A key question is what debt-stabilising level might be considered appropriate. Is it the 102 per cent that the OBR is predicting at the end of 2024/25 (the medium-term horizon)? Or is it the 75 per cent that was being forecast for this point back in the March budget? This has profound implications for the fiscal arithmetic and, specifically, for the primary balance (the difference between non-interest spending and receipts) that the public sector needs to run.

If the government accepts a higher debt-to-GDP ratio as a ‘new norm’ that eases the fiscal arithmetic somewhat. However, some economists would be concerned about the economic consequences of larger public-sector debts, most notably so-called potential crowding-out effects on private-sector investment if upward pressure on interest rates was to materialise (see the news item MMT – a Magic Money Tree or Modern Monetary Theory?).

Even if the higher stabilising debt level was deemed appropriate, the OBR’s report analysis suggests problems in the government meeting this because it could still be running a primary deficit of 3.7 per cent of GDP by 2024/25. Therefore, even with interest rates expected to be lower than economic growth rates in 2024/25 (a negative growth-corrected interest rate) that enable governments to run primary deficits and yet maintain debt-to-GDP ratios, the debt-stabilising primary deficit for 2024/25 is estimated at only 3.2 per cent. All in all, this points to difficult fiscal choices ahead.

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.
