Global long-term economic growth has slowed dramatically since the financial crisis of 2007–8. This can be illustrated by comparing the two 20-year periods 1988 to 2007 and 2009 to 2028 (where IMF forecasts are used for 2024 to 2028: see WEO Database under the Data link below). Over the two periods, average annual world growth fell from 3.8% to 3.1%. In advanced countries it fell from 2.9% to 1.6% and in developing countries from 4.8% to 4.3%. In the UK it fell from 2.4% to 1.2%, in the USA from 3.1% to 1.8% and in Japan from 1.9% to 0.5%.
In the UK, labour productivity growth in the production industries was 6.85% per annum from 1998 to 2006. If this growth rate had been maintained, productivity would have been 204% higher by the end of 2023 than it actually was. This is shown in the chart (click here for a PowerPoint).
The key driver of long-term economic growth is labour productivity, which can best be measured by real GDP per hour worked. This depends on three things: the amount of capital per worker, the productivity of this capital and the efficiency of workers themselves – the latter two giving total factor productivity (TFP). Productivity growth has slowed, and with it the long-term rate of economic growth.
If we are measuring growth in output per head of the population, as opposed to simple growth in output, then another important factor is the proportion of the population that works. With ageing populations, many countries are facing an increase in the proportion of people not working. In most countries, these demographic pressures are likely to increase.
A major determinant of long-term economic growth and productivity is investment. Investment has been badly affected by crises, such as the financial crisis and COVID, and by geopolitical tensions, such as the war in Ukraine and tensions between the USA and China and potential trade wars. It has also been adversely affected by government attempts to deal with rising debt caused by interventions following the financial crisis and COVID. The fiscal squeeze and, more recently higher interest rates, have dampened short-term growth and discouraged investment, thereby dampening long-term growth.
Another factor adversely affecting productivity has been a lower growth of allocative efficiency. Competition in many industries has declined as the rate of new firms entering and exiting markets has slowed. The result has been an increase in concentration and a growth in supernormal profits.
In the UK’s case, growth prospects have also been damaged by Brexit. According to Bank of England and OBR estimates, Brexit has reduced productivity by around 4% (see the blog: The costs of Brexit: a clearer picture). For many companies in the UK, Brexit has hugely increased the administrative burdens of trading with the EU. It has also reduced investment and led to a slower growth in the capital stock.
The UK’s poor productivity growth over many yeas is examined in the blog The UK’s poor productivity record.
Boosting productivity
So, how could productivity be increased and what policies could help the process?
Artificial intelligence. One important driver of productivity growth is technological advance. The rapid advance in AI and its adoption across much of industry is likely to have a dramatic effect on working practices and output. Estimates by the IMF suggest that some 40% of jobs globally and 60% in advanced countries could be affected – some replaced and others complemented and enhanced by AI. The opportunities for raising incomes are huge, but so too are the dangers of displacing workers and deepening inequality, as some higher-paid jobs are enhanced by AI, while many lower paid jobs are little affected and other jobs disappear.
AI is also likely to increase returns to capital. This may help to drive investment and further boost economic growth. However, the increased returns to capital are also likely to exacerbate inequality.
To guard against the growth of market power and its abuse, competition policies may need strengthening to ensure that the benefits of AI are widely spread and that new entrants are encouraged. Also training and retraining opportunities to allow workers to embrace AI and increase their mobility will need to be provided.
Training. And it is not just training in the use of AI that is important. Training generally is a key ingredient in encouraging productivity growth. In the UK, there has been a decline in investment in adult education and training, with a 70% reduction since the early 2000s in the number of adults undertaking publicly-funded training, and with average spending on training by employers decreasing by 27% per trainee since 2011. The Institute for Fiscal Studies identifies five main policy levers to address this: “public funding of qualifications and skills programmes, loans to learners, training subsidies, taxation of training and the regulation of training” (see link in articles below).
Competition. Another factor likely to enhance productivity is competition, both internationally and within countries. Removing trade restrictions could boost productivity growth; erecting barriers to protect inefficient domestic industry would reduce it.
Investment. Policies to encourage investment are also key to productivity growth. Private-sector investment can be encouraged by tax incentives. For example, in the UK the Annual Investment Allowance allows businesses to claim 100% of the cost of plant and machinery up to £1m in the year it is incurred. However, for tax relief to produce significant effects on investment, companies need to believe that the policy will stay and not be changed as economic circumstances or governments change.
Public-sector investment is also key. Good road and rail infrastructure and public transport are vital in encouraging private investment and labour mobility. And investment in health, education and training are a key part in encouraging the development of human capital. Many countries, the UK included, cut back on public-sector capital investment after the financial crisis and this has had a dampening effect on economic growth.
Regional policy. External economies of scale could be encouraged by setting up development areas in various regions. Particular industries could be attracted to specific areas, where local skilled workers, managerial expertise and shared infrastructure can benefit all the firms in the industry. These ‘agglomeration economies’ have been very limited in the UK compared with many other countries with much stronger regional economies.
Changing the aims and governance of firms. A change in corporate structure and governance could also help to drive investment and productivity. According to research by the think tank, Demos (see the B Lab UK article and the second report below), if legislation required companies to consider the social, economic and environmental impact of their business alongside profitability, this could have a dramatic effect on productivity. If businesses were required to be ‘purpose-led’, considering the interests of all their stakeholders, this supply-side reform could dramatically increase growth and well-being.
Such stakeholder-governed businesses currently outperform their peers with higher levels of investment, innovation, product development and output. They also have higher levels of staff engagement and satisfaction.

We have examined inflation in several blogs in recent months. With inflation at levels not seen for 40 years, this is hardly surprising. One question we’ve examined is whether the policy response has been correct. For example, in July, we asked whether the Bank of England had raised interest rates too much, too late. In judging policy, one useful distinction is between demand-pull inflation and cost-push inflation. Do they require the same policy response? Is raising interest rates to get inflation down to the target rate equally applicable to inflation caused by excessive demand and inflation caused by rising costs, where those rising costs are not caused by rising demand?
In terms of aggregate demand and supply, demand-pull inflation is shown by continuing rightward shifts in aggregate demand (AD); cost-push inflation is shown by continuing leftward/upward shifts in short-run aggregate supply (SRAS). This is illustrated in the following diagram, which shows a single shift in aggregate demand or short-run aggregate supply. For inflation to continue, rather than being a single rise in prices, the curves must continue to shift.
As you can see, the effects on real GDP (Y) are quite different. A rise in aggregate demand will tend to increase GDP (as long as capacity constraints allow). A rise in costs, and hence an upward shift in short-run aggregate supply, will lead to a fall in GDP as firms cut output in the face of rising costs and as consumers consume less as the cost of living rises.
The inflation experienced by the UK and other countries in recent months has been largely of the cost-push variety. Causes include: supply-chain bottlenecks as economies opened up after COVID-19; the war in Ukraine and its effects on oil and gas supplies and various grains; and avian flu and poor harvests from droughts and floods associated with global warming resulting in a fall in food supplies. These all led to a rise in prices. In the UK’s case, this was compounded by Brexit, which added to firms’ administrative costs and, according to the Bank of England, was estimated to cause a long-term fall in productivity of around 3 to 4 per cent.
The rise in costs had the effect of shifting short-run aggregate supply upwards to the left. As well as leading to a rise in prices and a cost-of-living squeeze, the rising costs dampened expenditure.
This was compounded by a tightening of fiscal policy as governments attempted to tackle public-sector deficits and debt, which had soared with the support measures during the pandemic. It was also compounded by rising interest rates as central banks attempted to bring inflation back to target.
Monetary policy response
Central banks are generally charged with keeping inflation in the medium term at a target rate set by the government or the central bank itself. For most developed countries, this is 2% (see table in the blog, Should central bank targets be changed?). So is raising interest rates the correct policy response to cost-push inflation?
One argument is that monetary policy is inappropriate in the face of supply shocks. The supply shocks themselves have the effect of dampening demand. Raising interest rates will compound this effect, resulting in lower growth or even a recession. If the supply shocks are temporary, such as supply-chain disruptions caused by lockdowns during the pandemic, then it might be better to ride out the problem and not raise interest rates or raise them by only a small amount. Already cost pressures are easing in some areas as supplies have risen.
If, however, the fall in aggregate supply is more persistent, such as from climate-related declines in harvests or the Ukraine war dragging on, or new disruptions to supply associated with the Israel–Gaza war, or, in the UK’s case, with Brexit, then real aggregate demand may need to be reduced in order to match the lower aggregate supply. Or, at the very least, the growth in aggregate demand may need to be slowed to match the slower growth in aggregate supply.
Huw Pill, the Chief Economist at the Bank of England, in a podcast from the Columbia Law School (see links below), argued that people should recognise that the rise in costs has made them poorer. If they respond to the rising costs by seeking higher wages, or in the case of businesses, by putting up prices, this will simply stoke inflation. In these circumstances, raising interest rates to cool aggregate demand may reduce people’s ability to gain higher wages or put up prices.
Another argument for raising interest rates in the face of cost-push inflation is when those cost increases are felt more than in other countries. The USA has suffered less from cost pressures than the UK. On the other hand, its growth rate is higher, suggesting that its inflation, albeit lower than in the UK, is more of the demand-pull variety. Despite its inflation rate being lower than in the UK, the problem of excess demand has led the Fed to adopt an aggressive interest rate policy. Its target rate is 5.25% to 5.50%, while the Bank of England’s is 5.25%. In order to prevent short-term capital outflows and a resulting depreciation in the pound, further stoking inflation, the Bank of England has been under pressure to mirror interest rate rises in the USA, the eurozone and elsewhere.

At the time of the 2016 referendum, the clear consensus among economists was that Brexit would impose net economic costs on the UK economy. The size of these costs would depend on the nature of post-Brexit trading relations with the EU. The fewer the new barriers to trade and the closer the alignment with the EU single market, the lower these costs would be.
The Brexit deal in the form of the EU-UK Trade and Cooperation Agreement (see also) applied provisionally from January 2021, after the end of the transition period, and came into force in May 2021. Although this is a free-trade deal in the sense that goods made largely in the UK or EU can be traded tariff-free between the two, the deal does not apply to services (e.g. financial services) or to goods where components made outside the UK or EU account for more than a certain percentage (the ‘rules of origin‘ condition). Also there has been a huge increase in documentation that must be completed to export to or import from the EU.
Even though the nature of the Brexit deal has been clear since it was signed in December 2020, assessing the impact of the extra barriers to trade it has created has been hard given the various shocks that have had a severe impact on the UK (and global) economy. First COVID-19 and the associated lockdowns had a direct effect on output and trade; second the longer-term international supply-chain disruptions have extended the COVID costs beyond the initial lockdowns and acted as a brake on recovery and growth; third the Russian invasion of Ukraine imposed a severe shock to energy and food markets; fourth these factors have created not just a supply shock but also an inflationary shock, which has resulted in central banks seeking to dampen demand by significantly raising interest rates. One worry among analysts was that the negative effects of such shocks might be greater on the UK economy than on other countries.
However, the negative effects of Brexit are now becoming clearer and various institutions have attempted to quantify the costs. These costs are largely in terms of lower GDP than otherwise. This results from:
- reduced levels of trade with the EU, thereby reducing the gains from exploiting comparative advantage;
- increased costs of trade with the EU;
- disruptions to supply chains;
- reduced competition from European firms, with many no longer exporting to the UK because of the costs;
- reduced inward investment;
- labour market shortages, particularly in certain areas such a hospitality, construction, social care and agriculture as many European workers have left the UK and fewer come;
- a reduction in productivity.
Here is a summary of the findings of different organisations.
The Office for Budget Responsibility (OBR)
The OBR has argued that Brexit as negotiated in the Trade and Cooperation Agreement:
will reduce long-run productivity by 4 per cent relative to remaining in the EU. This largely reflects our view that the increase in non-tariff barriers on UK-EU trade acts as an additional impediment to the exploitation of comparative advantage.21
In addition the OBR estimates that:
Both exports and imports will be around 15 per cent lower in the long run than if the UK had remained in the EU.21
Recent evidence supports this. According to the OBR:
UK and aggregate advanced economy goods export volumes fell by around 20 per cent during the initial wave of the pandemic in 2020. But by the fourth quarter of 2021 total advanced economy trade volumes had rebounded to 3 per cent above their pre-pandemic levels while UK exports remain around 12 per cent below.22
This assumption was repeated in the November 2022 Economic and Fiscal Outlook (p.26) 23. What is more, new trade deals will make little difference, either because they are a roll-over from previous EU trade deals with the respective country or have only a very small effect (e.g. the trade deal with Australia).
The Bank of England
The Bank of England, ever since the referendum in 2016, has forecast that Brexit would damage trade, productivity and GDP growth. In recent evidence to the House of Commons Treasury Committee5, Andrew Bailey, the Governor, stated that previous work by the Bank concluded that Brexit would reduce productivity by a bit over 3% and that this was still the Bank’s view.
His colleague, Dr Swati Dhingra, stated that, because of Brexit, there was a ‘much bigger slowdown in trade in the UK compared to the rest of the world’. She continued:
The simple way of thinking about what Brexit has done to the economy is that in the period after the referendum, the biggest depreciation that any of the world’s four major economies have seen overnight contributed to increasing prices [and] reduced wages. …We think that number is about 2.6% below the trend that real wages would have been on. Soon afterwards and before the TCA happened came the effects of the uncertainty that was unleashed, which basically translates into reduced business investment and less certainty of the FDI effects. Those tend to be very long-pay things.
She continued that now we are seeing significantly reduced trade directly as a result of the Brexit trade agreement (TCA).
Her colleague, Dr Catherine Mann, argued that ‘the small firms are the ones that are the most damaged, because the cost of the paperwork and so forth is a barrier’. This does not only affect UK firms exporting to the EU but also EU firms exporting to the UK. Reduced imports from EU firms reduces competition in the UK, which tends to lead to higher prices.
The Institute for Fiscal Studies
The IFS has consistently argued that Brexit, because of increased trade barriers with the EU, has reduced UK trade, productivity and GDP. In a recent interview6, its Director, Paul Johnson, stated that ‘Brexit, without doubt, has made us poorer than we would otherwise have been’. That, plus other convulsions, such as the mini-Budget of October 2022, have reduced foreigners’ confidence in the UK, with the result that investment in the UK and trade with the rest of the world have fallen.
Resolution Foundation
In a major Resolution Foundation report24, the authors argued that the effects of Brexit will take time to materialise fully and will occur in three distinct phases. First, in anticipation of permanent effects, the referendum caused sterling to depreciate and this adversely affected household incomes. What is more, the uncertainty about the future caused business investment to fall (but not inward FDI). Second, the Trade and Cooperation Act, by introducing trade barriers, reduced UK trade with the EU. But trade with the rest of the world also fell suggesting that Brexit is impacting UK trade openness and competitiveness more broadly. Third, there will be structural changes to the UK economy over the long-term which will adversely affect economic growth:
A less-open UK will mean a poorer and less productive one by the end of the decade, with real wages expected to fall by 1.8 per cent, a loss of £470 per worker a year, and labour productivity by 1.3 per cent, as a result of the long-run changes to trade under the TCA. This would be equivalent to losing more than a quarter of the last decade’s productivity growth.
Nuffield Trust
One of the key effects of Brexit has been on the labour market and especially on sectors, such as hospitality, agriculture, construction, health and social care. These sectors are experiencing labour shortages, in part due to EU nationals leaving the UK. In 2021, the Nuffield Trust looked at the supply of workers in health and social care25 and found that, as a result of increased bureaucratic hurdles, the number of EU/EFTA-trained nurses had declined since 2016. In social care, new immigration rules have made it virtually impossible to recruit from the EU. A more recent report looked at the recruitment of doctors in four specific specialties.26 In each case, although the number recruited from the EU/EFTA was still increasing, the rate of increase had slowed significantly. The reason appeared to be Brexit not COVID-19.
Ivalua
Research by Coleman Parkes for Ivalua18 shows that 80% of firms found Brexit to have been the biggest cause of supply-chain disruptions in the 12 months to August 2022, with 83% fearing the biggest disruptions from Brexit are yet to come. Brexit was found to have had a bigger effect on supply chains than the war in Ukraine, rising energy costs and COVID-19.
Centre for European Reform
Modelling conducted by John Springford27 used a ‘doppelgängers’ method to show the effects of Brexit on the UK economy. Each doppelgänger is ‘a basket of countries whose economic performance closely matches the UK’s before the Brexit referendum and the end of the transition period’. Comparing the UK’s performance with the doppelgänger can show the difference between leaving and not leaving the UK. Doppelgängers were estimated for GDP, investment (gross fixed capital formation), total services trade (exports plus imports) and total goods trade (ditto).
The results are sobering. In the final quarter of 2021, UK GDP is 5.2 per cent smaller than the modelled, doppelgänger UK; investment is 13.7 per cent lower; and goods trade, 13.6 per cent lower.
Economic and Social Research Institute (ESRI) (Ireland)
Similar results for UK trade have been obtained by Janez Kren and Martina Lawless in research conducted for the ESRI.28 They used product-level trade flows between the EU and all other countries in the world as a comparison group. This showed a 16% reduction in UK exports to the EU and a 20% reduction in UK imports from the EU relative to the scenario in which Brexit had not occurred.
British Chambers of Commerce (BCC) survey
According to a BCC survey of 1168 businesses33, 92% of which are SMEs, more than three quarters (77%) for which the Brexit deal is applicable say it is not helping them increase sales or grow their business and 56% say they have difficulties in adapting to the new rules for trading goods. The survey shows that UK firms are facing significant challenges in trying to trade with EU countries under the terms of the Trade and Cooperation Agreement. What is more, 80% of firms had seen the cost of importing increase; 53% had seen their sales margins decrease; and almost 70% of manufacturers had experienced shortages of goods and services from the EU.
Academic studies
Research at the Centre for Business Prosperity, Aston University, by Jun Du, Emine Beyza Satoglu and Oleksandr Shepotylo20, 29 found that UK exports to the EU ‘fell by an average of 22.9% in the first 15 months after the introduction of the EU-UK Trade and Cooperation Agreement’. The negative effect on UK exports persisted and deepened from January 2021 to March 2022. The research involved comparing actual trade with an ‘alternative UK economy’ model based on the UK having remained in the EU. What is more, the researchers found that there had been a reduction of 42% in the number of product varieties exported to the EU, with a large number of exporters simply ceasing to export to the EU and with many of the remaining exporters streamlining their product ranges.
Research at the LSE’s Centre for Economic Performance by Jan David Bakker, Nikhil Datta, Richard Davies and Josh De Lyon31 found that leaving the EU added an average of £210 to UK household food bills over the two years to the end of 2021. This amounted to a total cost to consumers of £5.8 billion. This confirmed the findings of previous research30 that the increase in UK-EU trade barriers led to food prices in the UK being 6% higher than they would have been.
Finally, a report from the Migration Observatory at the University of Oxford32 examined the effects of the ending of the free movement of labour from the EU to the UK. Visas are now required, but ‘low-wage occupations that used to rely heavily on EU workers are now ineligible for work visas, with some limited exceptions for social care and seasonal workers’. Many industries are facing labour shortages. Reasons include other factors, such as low pay and unattractive working conditions, and workers leaving the workforce during the pandemic and afterwards. But the end of free movement appears to have exacerbated these existing problems.

Questions
- Summarise the negative effects of Brexit on the UK economy.
- Why is it difficult to quantify these effects?
- Explain the ‘doppelgängers’ method of estimating the costs of Brexit? How reliable is this method likely to be?
- How have UK firms attempted to reduce the costs of exporting to the EU?
- Is Brexit the sole cause of a shortage of labour in many sectors in the UK?
Aggregate demand has been booming as the world bounces back from the pandemic. At the same time, aggregate supply is severely constrained. These supply constraints are making potential national income smaller – at least temporarily. The result is that many countries are heading for recession.
At the same time, supply constraints are causing prices to rise, especially energy and food prices. This cost-push inflation is made worse by the rises in aggregate demand.
The result is ‘stagflation’ – a recession, or stagnation, accompanied by high inflation. In the UK, the latest Bank of England Monetary Policy Report forecast that by the end of 2022, CPI inflation would be 13.1% and that in 2023, real GDP would fall by 1.5%.
This effect of an adverse supply shock accompanied by relatively buoyant aggregate demand (at least initially) can be illustrated with an aggregate demand and supply diagram. The supply shock is illustrated by an upward shift to the left of the short-run aggregate supply curve (SRAS). (If the shock is a direct rise in prices, then it can be seen as a vertical upward shift. If it is a fall in the total amount supplied, then it can be seen as a horizontal leftward shift.) In the diagram, aggregate supply shifts from SRAS1 to SRAS2. The price level rises from P1 to P2. If costs go on rising or supply goes on falling then the curve will go on shifting upwards to the left.
If the government responds by increasing benefits or reducing taxes, then, other things being
equal, aggregate demand will rise. In the diagram, the AD curve will shift to the right, e.g. from AD1 to AD2. Real GDP only falls to Y3 not Y2. However, the price level rises further: from P2 to P3.
Why has aggregate supply fallen?
There are several factors that have contributed to the fall in aggregate supply/rise in costs.
- Stretched supply chains, which had been adversely affected by Covid. Congestion at container ports has led to delays, with warehouses and shops being short of stock.
- Labour shortages, with many people not returning to the labour force after being laid off or furloughed, or only returning part time, leaving firms needing more people. The problem has been particularly acute in the UK, with many EU citizens having returned to the EU after Brexit and the UK having to rely increasingly on staff from outside the EU.
- The war in Ukraine. This has had a major impact on the supply of natural gas and oil. The war has also led to a fall in grain and other food supplies from Ukraine, as ports have been blockaded and there have been disruptions to planting and harvesting.
- Climate change is causing more severe weather events, such as droughts in Europe and western USA. The droughts of 2022 will compound the problem of food shortages and food price inflation.
- In the UK, Brexit costs, such as increased administrative burdens and difficulties in both exporting and importing, have dampened production and hence adversely impacted on aggregate supply.
- Increased industrial action. As the cost of living soars, unions are demanding pay increases to match the rise in the cost of living. Pay rises further increase firms’ costs – and the bigger the pay rises, the bigger the rise in costs.
The problem with a fall in aggregate supply is that it reduces real GDP. People as a whole are poorer. To use a common analogy, the national ‘pie’ has shrunk. Giving everyone a bigger knife and fork (i.e. a rise in nominal aggregate demand) will not make people better off. It just compounds the problem of rising prices, as the diagram shows.
In the short term, with GDP shrinking, there is a major issue of distribution. If the poor are to be given help so that they are not made even poorer, then other people will have been made worse off. In other words, their nominal incomes must rise more slowly than prices.
Monetary policy
Central banks generally have a mandate of keeping inflation close to 2% over the medium term. Their levers are changes in interest rates, underpinned by changes in the money supply – in extreme times by quantitative easing (creating money by buying assets with newly created money) or quantitative tightening (withdrawing money from the economy by selling assets). Central banks, faced by soaring inflation, have been raising interest rates. The Fed has recently raised the Federal Funds rate by 0.75 percentage points (75 basis points) and the Bank of England and the European Central Bank by 0.5 percentage points (50 basis points).
Raising interest rates reduces inflation by dampening aggregate demand. In the diagram, the AD curve shifts to the left (or shifts to the right less quickly). This will dampen inflation, as falling real demand will force firms to cut prices. But it will also force them to cut output and employment, thereby worsening the recession.
Central banks recognise this dilemma, but also recognise that if inflation is not brought rapidly under control, it could spiral upwards, with wages and prices chasing each other in a wage–price spiral, which only gets worse as inflationary expectations rise. The short-term pain of falling real income is a price worth paying for getting inflation under control.
Fiscal policy
In the short term, there is little that fiscal policy can do to raise real GDP. The focus, as it was during the pandemic, must therefore be in providing relief to those most in need.
In the UK, the energy price cap set by Ofgem will see likely energy bills for the typical household quadruple in just a year, from a little over £1000 per annum at January 2021 prices to over £4200 in predicted January 2023 prices. These higher prices partly reflect rising wholesale energy costs and partly the need for energy companies, in a process known as ‘backwardation’, to recoup hedging costs they have incurred so as not to be forced out of business.
Relief for consumers can be in various forms. For example, the government could pay subsidies to energy suppliers to cap prices at a lower level, perhaps just for the poorest households. Or it could pay grants to help people with their bills. Again, these could be targeted to the poorest families, or paid on a sliding scale according to income. Or VAT on gas and electricity could be scrapped.
Generally the more people are entitled to help, the more expensive it is for the government and hence the less generous the help per family is likely to be.
Then there is the question of whether such measures should be accompanied by a rise in broadly-based tax, such as income tax, or whether the government should borrow more, which would be likely to push up interest rates and increase the cost of servicing government debt.
One topic of debate in the Conservative leadership contest is whether taxes should be cut to help people struggling with the cost of living. Whilst such a policy, if carefully targeted to investment, might increase aggregate supply over the longer term, in the short term it will increase aggregate demand and will add to inflationary pressures.
Targeting tax cuts to the poor is difficult. Cutting income tax rates has the opposite effect. The rich pay more income tax than the poor and will benefit most from a cut in rates. An alternative is to raise personal allowances. This will provide a bigger percentage help to income taxpayers on lower incomes, but provides no help at all for the poorest people who currently pay no income tax.
Conclusion
The supply shocks are making countries poorer. The focus in the short term, therefore, needs to be on income distribution and how to help those suffering the most.
To end on a note of optimism: the energy shocks are causing governments to invest in alternative sources, such as wind, solar and nuclear. When these come on line, it is expected that energy prices will fall.
As far as overall inflation is concerned, although the Bank of England is forecasting CPI inflation of 13.1% by Q4 2022, it is also forecasting that this will have fallen to 5.5% by Q4 2023 and to just 0.8% by Q3 2024. Fingers crossed.
The UK left the EU on 31 January 2020 and entered an 11-month transition phase during which previous arrangements largely applied. On 30 December 2020, the UK and the EU signed the Trade and Cooperation Agreement (TCA) (see also), which set out the details of the post-Brexit trading arrangements between the UK and the EU after the ending of the transition period on 31 December 2020. The new arrangements have been implemented in stages so as to minimise disruption.
A major change was implemented on 1 January 2022, when full customs controls came into effect on imports into the UK from the EU. Later in the year a range of safety and security measures will be introduced, such as physical checks on live animals.
Not surprisingly, the anniversary of the TCA has been marked by many articles on Brexit: assessing its effects so far and looking into the future. Most of the articles see Brexit as having imposed net costs on the UK and the EU. They reflect the views of economists generally. As the first FT article linked below states, “The debate among economists on Brexit has rarely been about whether there would be a hit to growth and living standards, but rather how big a hit”.
The trade and GDP costs of Brexit
The Office for Budget Responsibility in October 2021 attempted to measure these costs in terms of the loss in trade and GDP. In October 2021, it stated:
Since our first post-EU referendum Economic and Fiscal Outlook in November 2016, our forecasts have assumed that total UK imports and exports will eventually both be 15 per cent lower than had we stayed in the EU. This reduction in trade intensity drives the 4 per cent reduction in long-run potential productivity we assume will eventually result from our departure from the EU.
…the evidence so far suggests that both import and export intensity have been reduced by Brexit, with developments still consistent with our initial assumption of a 15 per cent reduction in each.
This analysis is supported by evidence from John Springford, deputy director of the Centre for European Reform think-tank. He compares the UK’s actual performance with a ‘doppelgänger’ UK, which is an imaginary UK that has not left the EU. The doppelgänger used “is a subset of countries selected from a larger group of 22 advanced economies by an algorithm. The algorithm finds the countries that, when combined, create a doppelgänger UK that has the smallest possible deviation from the real UK data until December 2019, before the pandemic struck.” According to Springford, the shortfall in trade in October 2021 was 15.7 per cent – very much in line with the OBR’s forecasts.
Explanations of the costs
Why, then, have have been and will continue to be net economic costs from Brexit?
The main reason is that the UK has moved from being in the EU Single Market, a system of virtually friction-free trade and factor movements, to a trade agreement (the TCA) which, while being tariff and quota free for goods produced in the UK and the EU, involves considerable frictions. These frictions include greatly increased paperwork, which adds to the cost of trade. This has affected small businesses particularly, for whom the increased administrative costs generally represent a larger proportion of total costs than for large businesses.
Although EU tariffs are not imposed on goods wholly originating in the UK, they are imposed on many goods that are not. Under ‘rules of origin’ regulations, an item can only count as a British good if sufficient value or weight is added. If insufficient value is added, then customs charges are imposed. Similar rules apply from 1 January 2022 on goods imported into the Great Britain from the EU which are only partially made in the EU. The issue of rules of origin was examined in the blog A free-trade deal? Not really. Goods being moved between Great Britain and the EU are checked at ports and can only be released into the market if they have a valid customs declaration and have received customs clearance. This involves considerable paperwork for businesses. As the article below from Internet Retailing states:
UK and EU importers need to be able to state the origin of the goods they trade between the UK and EU. For some goods, exporters need to hold supplier declarations to show where they were made and where materials came from. From January 1, those issuing statements of origin for goods exported to the EU will need to hold the supplier declarations at the time that they export their goods, whereas up till now the those declarations could be supplied later.
Brexit has had considerable effects on the labour market. Many EU citizens returned to their home countries both before and after Brexit, creating labour shortages in many sectors. Also, it has become more difficult for UK citizens to work in the EU, with work permits required in most cases. This has had a major effect on some UK workers. For example, British touring musicians and performers find it difficult to tour, given the lack of an EU-wide visa waiver, ‘cabotage’ rules that ban large UK tour vehicles from making more than two stops before returning to the UK and new paperwork needed to take certain musical instruments into the EU.
Another issue concerns investment. Will greater restrictions in trade between the EU and the UK reduce inward investment to the UK, with international companies preferring to locate factories producing for Europe in the EU rather than the UK as the EU market is bigger than the UK market? So far, fears have not been realised as inward investment has held up well, partly because of the rapid bounce-back from the pandemic and the successful roll-out of the vaccine. Nevertheless, the UK’s dominance as a recipient of inward investment to Europe has been replaced by a three-way dominance of the UK, France and Germany, with France being the biggest recipient of the three in 2019 and 2020. It will be some years before the extent to which Brexit has damaged inward investment to the UK, if at all, becomes clear.
The TCA applies to goods, not services. One of the major concerns has been the implications of Brexit for financial services and the City of London. Before Brexit, financial institutions based in the UK had ‘passporting rights’. These allowed them to offer financial services across EU borders and to set up branches in EU countries easily. With the ending of the transition period in December 2020, these passporting rights have ceased. The EU has granted temporary ‘equivalence’ to such institutions until June 2022, but then it comes to an end and there is no prospect of deal on financial services in the near future. Indeed, the EU is actively trying to encourage more financial activity to move from the UK to the EU. Several financial institutions have already relocated all or part of their business from London to the EU.
The articles below examine these costs and many give examples of specific firms and how Brexit has impacted on them. As you will see, there are quite a lot of articles and you might just want to select a few. Or if this blog is being used for classes, the articles could be assigned to different students and used as the basis for discussion.
The future
Whilst the additional costs in terms of trade restrictions and paperwork are clear, it is too soon to know how well firms will be able to overcome them. Many of those who support Brexit argue that the UK now has freedom to impose lighter UK regulations on firms and that this could encourage economic growth. Other supporters of Brexit, however, argue that Brexit gives the UK government the opportunity to impose tougher environmental, safety and employment protection regulations. Again, it is too soon to know what direction the current and future governments will move.
Then there is the question of trade deals with non-EU countries. How many will there be? When will they be signed? What will their terms be? So far, the deals signed have largely been just a roll-over of the deals the UK previously had with these countries as a member of the EU. The one exception is the deal with Australia. But the gains from that are tiny – an estimated gain of between 0.02 and 0.08 per cent of GDP from 2035 (compared with the estimated 4 per cent loss from leaving the EU’s Single Market). Also there are fears by the UK agricultural sector that cheaper food from Australia, produced under lower standards, could undercut UK farmers, especially after the end of a 15-year transitional period. So far, a trade deal with the USA seems a long way off.
Then there are uncertainties about the Northern Ireland Protocol, under which there is an effective border between Great Britain and the EU down the Irish Sea, with free trade across the Northern Ireland–Republic of Ireland border. Will it be rewritten? Will the UK renege on its treaty commitments to impose checks on goods flowing between Northern Ireland and Great Britain?
Difficulties with the Northern Ireland Protocol, highlight another uncertainty and that is the political relationships between the UK and the EU, which have come under considerable strain with various post-Brexit disputes. Could these difficulties damage trade further and, if so, by how much?
What is clear is that there is considerable uncertainty about the future, a future that for some time is likely to be affected by the pandemic and its aftermath in both the UK and the EU. As the OBR states:
It is too early to reach definitive conclusions because:
- The terms of the TCA are yet to be implemented in full, meaning trade barriers will rise further as more of the deal comes into force. For example, the introduction of full checks on UK imports has recently been delayed until 2022.
- The full effect of the referendum outcome and higher trade barriers will probably take several years to come through, with businesses needing considerable time to adjust.
- The pandemic has delivered a large shock to UK and global trade volumes over the past 18 months, making it difficult to disentangle the separate effect of leaving the EU.
- Finally, trade data tend to be relatively volatile and are revised frequently, rendering any initial conclusions subject to change as the data are revised.

- Summarise the reasons why the volume of trade between the UK and the EU is likely to be below the level it would have been if the UK had remained in the Single Market.
- How can economists disentangle the effects of Brexit from the effects of Covid? How is the ‘doppelgänger UK’ model used for this purpose?
- Are there any economic advantages of the UK’s exit from the EU? If so, what are they and how significant are they?
- The OBR forecasts that there will be a long-term reduction of 15 per cent in both UK imports from the EU and UK exports to the EU. What might cause this figure to be (a) greater than 15 per cent; (b) less than 15 per cent?
