The UK’s poor productivity record

In its latest World Economic Outlook update, the IMF forecasts that the UK in 2023 will be the worst performing economy in the G7. Unlike all the other countries and regions in the report, only the UK economy is set to shrink. UK real GDP is forecast to fall by 0.6% in 2023 (see Figure 1: click here for a PowerPoint). In the USA it is forecast to rise by 1.4%, in Germany by 0.1%, in France by 0.7% and in Japan by 1.8%. GDP in advanced countries as a whole is forecast to grow by 1.2%, while world output is forecast to grow by 2.9%. Developing countries are forecast to grow by 4.0%, with China and India forecast to grow by 5.2% and 6.1%, respectively. And things are not forecast to be a lot better for the UK in 2024, with growth of 0.9% – bottom equal with Japan and Italy.

Low projected growth in the UK in part reflects the tighter fiscal and monetary policies being implemented to curb inflation, which is slow to fall thanks to tight labour markets and persistently higher energy prices. The UK is particularly exposed to high wholesale gas prices, with a larger share of its energy coming from natural gas than most countries.

But the UK’s lower forecast growth relative to other countries reflects a longer-term problem in the UK and that is the slow rate of productivity growth. This is illustrated in Figure 2, which shows output (GDP) per hour worked in major economies, indexed at 100 in 2008 (click here for a PowerPoint). As you can see, the growth in productivity in the UK has lagged behind that of the other economies. The average annual percentage growth in productivity is shown next to each country. The UK’s growth in productivity since 2008 has been a mere 0.3% per annum.

Causes of low productivity/low productivity growth

A major cause of low productivity growth is low levels of investment in physical capital. Figure 3 shows investment (gross capital formation) as a percentage of GDP for the G7 countries from the 2007–8 financial crisis to the year before the pandemic (click here for a PowerPoint). As you can see, the UK performs the worst of the seven countries.

Part of the reason for the low level of private investment is uncertainty. Firms have been discouraged from investing because of a lack of economic growth and fears that this was likely to remain subdued. The problem was compounded by Brexit, with many firms uncertain about their future markets, especially in the EU. COVID affected investment, as it did in all countries, but supply chain problems in the aftermath of COVID have been worse for the UK than many countries. Also, the UK has been particularly exposed to the effects of higher gas prices following the Russian invasion of Ukraine, as a large proportion of electricity is generated from natural gas and natural gas is the major fuel for home heating.

Part of the reason is an environment that is unconducive for investment. Access to finance for investment is more difficult in the UK and more costly than in many countries. The financial system tends to have a short-term focus, with an emphasises on dividends and short-term returns rather than on the long-term gains from investment. This is compounded by physical infrastructure problems with a lack of investment in energy, road and rail and a slow roll out of advances in telecoms.


To help fund investment and drive economic growth, in 2021 the UK government established a government-owned UK Infrastructure Bank. This has access to £22 billion of funds. However, as The Conversation article below points out:

According to a January 2023 report from Westminster’s Public Accounts Committee, 18 months after its launch the bank had only deployed ‘£1 billion of its £22 billion capital to 10 deals’, and had employed just 16 permanent staff ‘against a target of 320’. The committee also said it was ‘not convinced the bank has a strategic view of where it best needs to target its investments’.

Short-termism is dominant in politics, with ministers keen on short-term results in time for the next election, rather than focusing on the long term when they may no longer be in office. When the government is keen to cut taxes and find ways of cutting government expenditure, it is often easier politically to cut capital expenditure rather than current expenditure. The Treasury oversees fiscal policy and its focus tends to be short term. What is needed is a government department where the focus is on the long term.

One problem that has impacted on productivity is the relatively large number of people working for minimum wages or a little above. Low wages discourage firms from making labour-saving investment and thereby increasing labour productivity. It will be interesting to see whether the labour shortages in the UK, resulting from people retiring early post-COVID and EU workers leaving, will encourage firms to make labour-saving investment.

Another issue is company taxation. Until recently, countries have tended to compete corporate taxes down in order to attract inward investment. This was stemmed somewhat by the international agreement at the OECD that Multinational Enterprises (MNEs) will be subject to a minimum 15% corporate tax rate from 2023. The UK is increasing corporation tax from 19% to 25% from April 2023. It remains to be seen what disincentive effect this will have on inward investment. Although the new rate is similar to, or slightly lower, than other major economies, there are some exceptions. Ireland will have a rate of just 15% and is seen as a major alternative to the UK for inward investment, especially with its focus on cheaper green energy. AstraZeneca has just announced that instead of building its new ‘state-of-the-art’ manufacturing plant in England close to its two existing plats in NW England, it will build it in Ireland instead, quoting the UK’s ‘discouraging’ tax rates and price capping for drugs by the NHS.

And it is not just physical investment that affects productivity, it is the quality of labour. Although a higher proportion of young people go to university (close to 50%) than in many other countries, the nature of the skills sets acquired may not be particularly relevant to employers.

What is more, relatively few participate in vocational education and training. Only 32% of 18-year olds have had any vocational training. This compares with other countries, such as Austria, Denmark and Switzerland where the figure is over 65%. Also a greater percentage of firms in other countries, such as Germany, employ people on vocational training schemes.

Another aspect of labour quality is the quality of management. Poor management practices in the UK and inadequate management training and incentives have resulted in a productivity gap with other countries. According to research by Bloom, Sadun & Van Reenen (see linked article below, in particular Figure A5) the UK has an especially large productivity gap with the USA compared with other countries and the highest percentage of this gap of any country accounted for by poor management.

Solutions

Increasing productivity requires a long-term approach by both business and government. Policy should be consistent, with no ‘chopping and changing’. The more that policy is changed, the less certain will business be and the more cautious about investing.

As far a government investment is concerned, capital investment needs to be maintained at a high level if significant improvements are to be made in the infrastructure necessary to support increased growth rates. As far as private investment is concerned, there needs to be a focus on incentives and finance. If education and training are to drive productivity improvements, then there needs to be a focus on the acquisition of transferable skills.

Such policies are not difficult to identify. Carrying them out in a political environment focused on the short term is much more difficult.

The growth of autarky: is globalisation dead?

Over the decades, economies have become increasingly interdependent. This process of globalisation has involved a growth in international trade, the spread of technology, integrated financial markets and international migration.

When the global economy is growing, globalisation spreads the benefits around the world. However, when there are economic problems in one part of the world, this can spread like a contagion to other parts. This was clearly illustrated by the credit crunch of 2007–8. A crisis that started in the sub-prime market in the USA soon snowballed into a worldwide recession. More recently, the impact of Covid-19 on international supply chains has highlighted the dangers of relying on a highly globalised system of production and distribution. And more recently still, the war in Ukraine has shown the dangers of food and fuel dependency, with rapid rises in prices of basic essentials having a disproportionate effect on low-income countries and people on low incomes in richer countries.

Moves towards autarky

So is the answer for countries to become more self-sufficient – to adopt a policy of greater autarky? Several countries have moved in this direction. The USA under President Trump pursued a much more protectionist agenda than his predecessors. The UK, although seeking new post-Brexit trade relationships, has seen a reduction in trade as new barriers with the EU have reduced UK exports and imports as a percentage of GDP. According to the Office for Budget Responsibility’s November 2022 Economic and Fiscal Outlook, Brexit will result in the UK’s trade intensity being 15 per cent lower in the long run than if it had remained in the EU.

Many European countries are seeking to achieve greater energy self-sufficiency, both as a means of reducing reliance on Russian oil and gas, but also in pursuit of a green agenda, where a greater proportion of energy is generated from renewables. More generally, countries and companies are considering how to reduce the risks of relying on complex international supply chains.

Limits to the gains from trade

The gains from international trade stem partly from the law of comparative advantage, which states that greater levels of production can be achieved by countries specialising in and exporting those goods that can be produced at a lower opportunity cost and importing those in which they have a comparative disadvantage. Trade can also lead to the transfer of technology and a downward pressure on costs and prices through greater competition.

But trade can increase dependence on unreliable supply sources. For example, at present, some companies are seeking to reduce their reliance on Taiwanese parts, given worries about possible Chinese actions against Taiwan.

Also, governments have been increasingly willing to support domestic industries with various non-tariff barriers to imports, especially since the 2007–8 financial crisis. Such measures include subsidies, favouring domestic firms in awarding government contracts and using regulations to restrict imports. These protectionist measures are often justified in terms of achieving security of supply. The arguments apply particularly starkly in the case of food. In the light of large price increases in the wake of the Ukraine war, many countries are considering how to increase food self-sufficiency, despite it being more costly.

Also, trade in goods involves negative environmental externalities, as freight transport, whether by sea, air or land, involves emissions and can add to global warming. In 2021, shipping emitted over 830m tonnes of CO2, which represents some 3% of world total CO2 emissions. In 2019 (pre-pandemic), the figure was 800m tonnes. The closer geographically the trading partner, the lower these environmental costs are likely to be.

The problems with a globally interdependent world have led to world trade growing more slowly than world GDP in recent years after decades of trade growth considerably outstripping GDP growth. Trade (imports plus exports) as a percentage of GDP peaked at just over 60% in 2008. In 2019 and 2021 it was just over 56%. This is illustrated in the chart (click here for a PowerPoint). Although trade as a percentage of GDP rose slightly from 2020 to 2021 as economies recovered from the pandemic, it is expected to have fallen back again in 2022 and possibly further in 2023.

But despite this reduction in trade as a percentage of GDP, with de-globalisation likely to continue for some time, the world remains much more interdependent than in the more distant past (as the chart shows). Greater autarky may be seen as desirable by many countries as a response to the greater economic and political risks of the current world, but greater autarky is a long way from complete self-sufficiency. The world is likely to remain highly interdependent for the foreseeable future. Reports of the ‘death of globalisation’ are premature!

The costs of Brexit: a clearer picture

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.

From Reaganomics to Trussonomics

In her bid to become Conservative party leader, Liz Truss promised to make achieving faster economic growth her number-one policy objective. This would involve pursuing market-orientated supply-side policies.

These policies would include lower taxes on individuals to encourage people to work harder and more efficiently, and lower taxes on business to encourage investment. The policy would also involve deregulation, which would again encourage investment, both domestic and inward investment from overseas. These proposals echoed the policies pursued in the 1980s by President Ronald Reagan in the USA and Margaret Thatcher in the UK.

On September 23, the new Chancellor, Kwasi Kwarteng, presented a ‘mini-Budget’ – although the size of the changes made it far from ‘mini’. This, as anticipated, included policies intended to boost growth, including scrapping the 45% top rate of income tax, which is currently paid by people earning over £150 000 (a policy withdrawn on 3 October after massive objections), cutting the basic rate of income tax from 20% to 19%, scrapping the planned rise in corporation tax from 19% to 25%, scrapping the planned rise in national insurance by 1.25 percentage points, a cut in the stamp duty on house purchase and scrapping the limit placed on bankers’ bonuses. In addition, he announced the introduction of an unlimited number of ‘investment zones’ which would have lower business taxes, streamlined planning rules and lower regulation. The policies would be funded largely from extra government borrowing.

Theoretically, the argument is simple. If people do work harder and firms do invest more, then potential GDP will rise – a rise in aggregate supply. This can be shown on an aggregate demand and supply diagram. If the policy works, the aggregate supply curve will shift to the right. Real GDP will rise and there will be downward pressure on prices. In Figure 1, real GDP will rise from Y0 to Y1 and the price level will fall from P0 to P1. However, things are not as simple as this. Indeed, there are two major problems.

The first concerns whether tax cuts will incentivise people to work harder. The second concerns what happens to aggregate demand. I addition to this, the policies are likely to have a profound effect on income distribution.

Tax cuts and incentives

Cutting the top rate of income tax would have immediately given people at the top of the income scale a rise in post-tax income. This would have created a substitution effect and an income effect. Each extra pound that such people earn would be worth more in post-tax income – 60p rather than 55p. This would provide an incentive for people to substitute work for leisure as work is now more rewarding. This is the substitution effect. On the other hand, with the windfall of extra income, they now would have needed to work less in order to maintain their post-tax income at its previous level. They may well indeed, therefore, have decided to work less and enjoy more leisure. This is the income effect.

With the diminishing marginal utility of income, generally the richer people are, the bigger will be the income effect and the smaller the substitution effect. Thus, cutting the top rate of income tax may well have led to richer people working less. There is no evidence that the substitution effect would be bigger.

If top rates of income tax are already at a very high level, then cutting then may well encourage more work. After all, there is little incentive to work more if the current rate of tax is over 90%, say. Cutting them to 80% could have a big effect. This was the point made by Art Laffer, one of Ronald Reagan’s advisors. He presented his arguments in terms of the now famous ‘Laffer curve’, shown in Figure 2. This shows the total tax revenue raised at different tax rates.

If the average tax rate were zero, no revenue would be raised. As the tax rate is raised above zero, tax revenues will increase. The curve will be upward sloping. Eventually, however, the curve will peak (at tax rate t1). Thereafter, tax rates become so high that the resulting fall in output more than offsets the rise in tax rate. When the tax rate reaches 100 per cent, the revenue will once more fall to zero, since no one will bother to work.

If the economy were currently to the right of t1, then cutting taxes would increase revenue as there would be a major substitution effect. However, most commentators argue that the UK economy is to the left of t1 and that cutting the top rate would reduce tax revenues. Analysis by the Office for Budget Responsibility in 2012 suggested that t1 for the top rate of income tax was at around 48% and that cutting the rate below that would reduce tax revenue. Clearly according to this analysis, 40% is considerably below t1.

As far as corporation tax is concerned, the 19% rate is the lowest in the G20 and yet the UK suffers from low rates of both domestic investment and inward direct investment. There is no evidence that raising it somewhat, as previously planned, will cut investment. And as far as individual entrepreneurs are concerned, cutting taxes is likely to have little effect on the desire to invest and expand businesses. The motivation of entrepreneurs is only partly to do with the money. A major motivation is the sense of achievement in building a successful business.

Creating investment zones with lower taxes, no business rates and lower regulations may encourage firms to set up there. But much of this could simply be diverted investment from elsewhere in the country, leaving overall investment little changed.

To assess these questions, the government needs to model the outcomes and draw on evidence from elsewhere. So far this does not seem to have happened. They government did not even present a forecast of the effects of its policies on the public finances, something that the OBR normally presents at Budget time. This was one of the reasons for the collapse in confidence of sterling and gilts (government bonds) in the days following the mini-Budget.

Effects on aggregate demand

Cutting taxes and financing them from borrowing will expand aggregate demand. In Figure 1, the AD curve will also shift to the right and this will push up prices. Inflation is already a serious problem in the economy and unfunded tax cuts will make it worse. Higher inflation will result in the Bank of England raising interest rates further to curb aggregate demand. But higher interest rates, by raising borrowing costs, are likely to reduce investment, which will have a negative supply-side effect.

The problem here is one of timing. Market-orientated supply-side policies, if they work to increase potential GDP, will take time – measured in years rather than months. The rise in aggregate demand will be much quicker and will thus precede the rise in supply. This could therefore effectively kill off the rise in supply as interest rates rise, the exchange rate falls and the economy is pushed towards recession. Indeed, the mini-Budget immediately sparked a run on the pound and the exchange rate fell.

The rising government debt may force the government to make cuts in public expenditure. Rather than cutting current expenditure on things such as nurses, teachers and benefits, it is easier to cut capital expenditure on things such as roads and other infrastructure. But this will have adverse supply-side effects.

Effects on income distribution

Those advocating market-orientated supply-side policies argue that, by making GDP bigger, everyone can gain. They prefer to focus on the size of the national ‘pie’ rather than its distribution. If the rich initially gain, the benefits will trickle down to the poorest in society. This trickle-down theory was popular in the 1980s with politicians such as Margaret Thatcher and Ronald Reagan and, more recently, with Republican presidents, such as Goerge W Bush and Donald Trump. There are two problems with this, however.

The first, which we have already seen, is whether such policies actually do increase the size of the ‘pie’.

The second is how much does trickle down. During the Thatcher years, income inequality in the UK grew, as it did in the USA under Ronald Reagan. According to an IMF study in 2015 (see the link to the IMF analysis below), policies that increase the income share of the poor and the middle class do increase growth, while those that raise the income share of the top 20 per cent result in lower growth.

After the mini-Budget was presented, the IMF criticised it for giving large untargeted tax cuts that would heighten inequality. The poor would gain little from the tax cuts. The changes to income tax and national insurance mean that someone earning £20 000 per year will gain just £167 per year, while someone earning £200 000 will gain £5220. What is more, the higher interest rates and higher prices resulting from the lower exchange rate are likely to wipe out the modest gains to the poor.

Soaring gas prices (updated 1/10/22)

International wholesale gas prices have soared in recent months. This followed a cold winter in 2021/22 across Europe, the bounceback in demand as economies opened up after COVID and, more recently, pressure on supplies since the Russian invasion of Ukraine and the resulting restricted gas supplies from Russia. The price of gas traded on the UK wholesale market is shown in Chart 1 (click here for a PowerPoint). Analysts are forecasting that the wholesale price of gas will continue to rise for some time. The higher price of gas has had a knock-on effect on wholesale electricity prices, as gas-fired power stations are a major source of electricity generation and electricity prices.

In the UK, domestic fuel prices were capped by the regulator, Ofgem. The cap reflected wholesale prices and was designed to allow electricity suppliers to make reasonable but not excessive profits. The cap was adjusted every six months, but this was been reduced to three months to reflect the rapidly changing situation. Prices are capped for both gas and electricity for both the standing charge and the rate per kilowatt hour (kWh). This is illustrated in Chart 2 (click here for a PowerPoint).

The effects of the cap were then projected in terms of a total annual bill for a typical household consuming 12 000 kWh of gas and 2900 kWh of electricity. Chart 3 shows the typical fuel bill for the last four price caps and, prior to the mini-Budget of 23 September, the projected price caps for the first and second quarters of 2023 based on forecasts at the time of wholesale prices (click here for a PowerPoint). As you can see, wholesale gas and electricity prices account for an increasing proportion of the total bill. The remaining elements in cost consist of profits (1.9% assumed), VAT (5%), operating costs, grid connection costs and green levies (around £153). The chart shows that, without government support for prices, the price cap would have risen by 80.6% in October 2022 and was projected to rise by a further 51% in January 2023 and by another 23% in March 2023. If this were to have been the case, then prices would have risen by 481% between the summer of 2021 and March 2023.

This was leading to dire warnings of extreme fuel poverty, with huge consequences for people’s health and welfare, which would put extra demands on an already stretched health service. Many small businesses would not be able to survive the extra fuel costs, which would lead to bankruptcies and increased unemployment.

Future wholesale gas prices

Energy market analysts expect wholesale gas prices to remain high throughout 2023, with little likelihood that gas supplies from Russia will increase. Some European countries, such as Germany, have been buying large amounts of gas to fill storage facilities before winter and before prices rise further. This has added to demand.

The UK, however, has only limited storage facilities. Although it is not an importer of gas from Russia and so, in one sense, storage facilities are less important at the current time, wholesale gas prices reflect international demand and supply and thus gas prices in the UK will be directly affected by an overall global shortage of supply.

What would have been the response to the projected rise in gas prices? Eventually demand would fall as substitute fuels are used for electricity generation. But demand is highly inelastic. People cannot readily switch to alternative sources of heating. Most central heating is gas fired. People may reduce consumption of energy by turning down their heating or turning it off altogether, but such reductions are likely to be a much smaller percentage than the rise in price. Thus, despite some use of other fuels and despite people cutting their energy usage, people would still end up spending much more on energy.

Over the longer term, new sources of supply of gas, including liquified natural gas (LNG), may increase supply. And switching to green energy sources for electricity generation, may bring the price of electricity back down and lead to some substitution been gas and electricity in the home and businesses. Also improved home insulation and the installation of heat pumps and solar panels in homes, especially in new builds, may reduce the demand for gas. But these changes take time. Chart 4 illustrates the situation (click here for a PowerPoint).

Both demand and supply are relatively inelastic. The initial demand and supply curves are D1 and S1. Equilibrium price is P1 (point a). There is now a fall in supply. Supply shifts to S2. With an inelastic demand, there is a large rise in price to P2 (point b).

Over two or three years, there is a modest fall in demand (as described above) to D2 and a modest rise in supply to S3. Price falls back somewhat to P3 (point c). Over a longer period of time, these shifts would be greater and the price would fall further.

Possible policy responses

What could the government do to alleviate the problem? Consensus was that the new Conservative Prime Minister, Liz Truss, and her Chancellor, Kwasi Kwarteng, would have to take radical measures if many households were to avoid severe hardship and debt. One proposal was to reduce VAT on domestic energy from 5% to zero and to cut green levies. Although this would help, it would make only a relatively small dent in people’s rising bills.

Another proposal was to give people cash payments to help with their bills. The more generous and widespread these payments, the more costly they would be.

One solution here would be to impose larger windfall taxes on oil and gas producers (as opposed to retailers). Their profits have soared as oil and gas prices have soared. Such a move is generally resisted by those on the right of politics, arguing that it could discourage investment in energy production. Those on the centre and left of politics argue that the profits are the result of global factors and not because of wise business decisions by the energy producers. A windfall tax would only take away these excess profits.

The EU has agreed a tax on fossil fuel companies’ surplus profits made either this year or next. It is also introducing a levy on the excess revenues that other low-cost power producers make from higher electricity prices.

Another proposal was to freeze retail energy prices at the current or some other level. This would make it impossible for energy suppliers to cover their costs and so they would have to be subsidised. This again would be very expensive and would require substantially increased borrowing at a time when interest rates are rising, or increased taxation at a time when people’s finances are already squeezed by higher inflation. An alternative would be to cap the price North Sea producers receive. As around half of the UK’s gas consumption is from the North Sea, this would help considerably if it could be achieved, but it might be difficult to do so given that the gas is sold onto international markets.

One proposal that was gaining support from energy producers and suppliers is for the government to set up a ‘deficit fund’. Energy suppliers (retailers) would freeze energy prices for two years and take out state-backed loans from banks. These would then be paid back over time by prices being capped sufficiently high to cover costs (which, hopefully, by then would be lower) plus repayments.

Another policy response would be to decouple electricity prices from the wholesale price of gas. This is being urgently considered in the EU, and Ofgem is also consulting on such a measure. This could make wholesale electricity prices reflect the costs of the different means of generation, including wind, solar and nuclear, and would see a fall in wholesale electricity prices. At the moment, generators using these methods are making large profits.

The government’s response

On September 23, the government held a mini-Budget. One of its key elements was a capping of the unit price of energy for both households and firms. The government called this the Energy Price Guarantee. For example, those households on a variable dual-fuel, direct-debit tariff would pay no more than 34.0p/kWh for electricity and 10.3p/kWh for gas. Standing charges are capped at 46p per day for electricity and 28p per day for gas. These rates will apply for 2 years from 1/10/22 and should give an average annual household bill of £2500.

Although the government has widely referred to the ‘£2500 cap’, it is the unit price that is capped, not the annual bill. It is still the case that the more you consume, the more you will pay. As you can see from Chart 3, the average £2500 still represents an average increase per annum of just over £500 per household and is almost double the cap of £1277 a year ago. It will thus still put considerable strain on many household finances.

For businesses, prices will be capped for 6 months from 1 October at 21.1p per kWh for electricity and 7.5p per KWh for gas – considerably lower than for domestic consumers.

The government will pay subsidies to the retail energy companies to allow them to make sufficient, but not excess, profit. These subsidies are estimated to cost around £150 billion. This will be funded by borrowing, not by tax increases, with the government ruling out a windfall tax on North Sea oil and gas extracting companies. Indeed, the mini-Budget contained a number of tax reductions, including scrapping the 45% top rate of income tax, cutting the basic rate of income tax from 20% to 19% and scrapping the planned rise in corporation tax from 19% to 25%.
