A four-day week – a solution to sluggish productivity growth?

In two previous posts, one at the end of 2019 and one in July 2021, we looked at moves around the world to introduce a four-day working week, with no increase in hours on the days worked and no reduction in weekly pay. Firms would gain if increased worker energy and motivation resulted in a gain in output. They would also gain if fewer hours resulted in lower costs.

Workers would be likely to gain from less stress and burnout and a better work–life balance. What is more, firms’ and workers’ carbon footprint could be reduced as less time was spent at work and in commuting.

If the same output could be produced with fewer hours worked, this would represent an increase in labour productivity measured in output per hour.

The UK’s poor productivity record since 2008

Since the financial crisis of 2007–8, the growth in UK productivity has been sluggish. This is illustrated in the chart, which looks at the production industries: i.e. it excludes services, where average productivity growth tends to be slower. (Click here for a PowerPoint of the chart.)

Prior to the crisis, from 1998 to 2007, UK productivity in the production industries grew at an annual rate of 6.1%. From 2007 to the start of the pandemic in 2020, the average annual productivity growth rate in these industries was a mere 0.5%.

It grew rapidly for a short time at the start of the pandemic, but this was because many businesses temporarily shut down or went to part-time working, and many of these temporary job cuts were low-wage/low productivity jobs. If you take services, the effect was even stronger as sectors such as hospitality, leisure and retail were particularly affected and labour productivity in these sectors tends to be low. As industries opened up and took on more workers, so average productivity fell back. In the four quarters to 2022 Q3 (the latest data available), productivity in the production industries fell by 6.8%.

If you project the average productivity growth rate from 1998 to 2007 of 6.1% forwards (see grey dashed line), then by 2022 Q3, output per hour in the production industries would have been 21/4 times (125%) higher than it actually was. This is a huge productivity gap.

Productivity in the UK is lower than in many other competitor countries. According to the ONS, output per hour in the UK in 2021 was $59.14 in the UK. This compares with an average of $64.93 for the G7 countries, $66.75 in France, £68.30 in Germany, $74.84 in the USA, $84.46 in Norway and $128.21 in Ireland. It is lower, however, in Italy ($54.59), Canada ($53.97) and Japan ($47.28).

As we saw in the blog, The UK’s poor productivity record, low UK productivity is caused by a number of factors, not least the lack of investment in physical capital, both by private companies and in public infrastructure, and the lack of investment in training. Other factors include short-termist attitudes of both politicians and management and generally poor management practices. But one cause is the poor motivation of many workers and the feeling of being overworked. One solution to this is the four-day week.

Latest evidence on the four-day week

Results have just been released of a pilot programme involving 61 companies and non-profit organisations in the UK and nearly 3000 workers. They took part in a six-month trial of a four-day week, with no increase in hours on the days worked and no loss in pay for employees – in other words, 100% of the pay for 80% of the time. The trial was a success, with 91% of organisations planning to continue with the four-day week and a further 4% leaning towards doing so.

The model adopted varied across companies, depending on what was seen as most suitable for them. Some gave everyone Friday off; others let staff choose which day to have off; others let staff work 80% of the hours on a flexible basis.

There was little difference in outcomes across different types of businesses. Compared with the same period last year, revenues rose by an average of 35%; sick days fell by two-thirds and 57% fewer staff left the firms. There were significant increases in well-being, with 39% saying they were less stressed, 40% that they were sleeping better; 75% that they had reduced levels of burnout and 54% that it was easier to achieve a good work–life balance. There were also positive environmental outcomes, with average commuting time falling by half an hour per week.

There is growing pressure around the world for employers to move to a four-day week and this pilot provides evidence that it significantly increases productivity and well-being.

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.

A Spring dose of fiscal policy

On March 23, Rishi Sunak, the UK’s Chancellor of the Exchequer, delivered his Spring Statement, in which he announced changes to various taxes and grants. These measures were made against the background of rising inflation and falling living standards.

CPI inflation, currently at 6.2%, is still rising and the Office for Budget Responsibility forecasts that inflation will average 7.4% this year. The poor spend a larger proportion of their income on energy and food than the rich. With inflation rates especially high for gas, electricity and basic foodstuffs, the poor have been seen their cost of living rise by considerably more than the overall inflation rate.

According to the OBR, the higher inflation, by reducing real income and consumption, is expected to reduce the growth in real GDP this year from the previously forecast 6% to 3.8% – a much smaller bounce back from the fall in output during the early stages of the pandemic. Despite this growth in GDP, real disposable incomes will fall by an average of £488 per person this year. As the OBR states:

With inflation outpacing growth in nominal earnings and net taxes due to rise in April, real living standards are set to fall by 2.2 per cent in 2022/23 – their largest financial year fall on record – and not recover their pre-pandemic level until 2024/25.

Fiscal measures

The Chancellor announced a number of measures, which, he argued, would provide relief from rises in the cost of living.

  • Previously, the Chancellor had announced that national insurance (NI) would rise by 1.25 percentage points this April. In the Statement he announced that the starting point for paying NI would rise from a previously planned £9880 to £12 570 (the same as the starting point for income tax). This will more than offset the rise in the NI rate for those earning below £32 000. This makes the NI system slightly more progressive than before. (Click here for a PowerPoint of the chart.)
  • A cut in fuel duty of 5p per litre. The main beneficiaries will be those who drive more and those with bigger cars – generally the better off. Those who cannot afford a car will not benefit at all, other than from lower transport costs being passed on in lower prices.
  • The 5% VAT on energy-saving household measures such as solar panels, insulation and heat pumps will be reduced to zero.
  • The government’s Household Support Fund will be doubled to £1bn. This provides money to local authorities to help vulnerable households with rising living costs.
  • Research and development tax credits for businesses will increase and small businesses will each get another £1000 per year in the form of employment allowances, which reduce their NI payments. He announced that taxes on business investment will be further cut in the Autumn Budget.
  • The main rate of income tax will be cut from 20% to 19% in two years’ time. Unlike the rise in NI, which only affects employment and self-employment income, the cut in income tax will apply to all incomes, including rental and savings income.

Fiscal drag

The Chancellor announced that public finances are stronger than previously forecast. The rapid growth in tax receipts has reduced public-sector borrowing from £322 billion (15.0 per cent of GDP) in 2020/21 to an expected £128 billion (5.4 per cent of GDP) in 2021/22, £55 billion less than the OBR forecast in October 2021. This reflects not only the growth in the economy, but also inflation, which results in fiscal drag.

Fiscal drag is where rises in nominal incomes mean that the average rate of income tax rises. As tax thresholds for 2022/23 are frozen at 2021/22 levels, a greater proportion of incomes will be taxed at higher rates and tax-free allowances will account for a smaller proportion of incomes. The higher the rate of increase in nominal incomes, the greater fiscal drag becomes. The higher average rate of tax drags on real incomes and spending. On the other hand, the extra tax revenue reduces government borrowing and gives the government more room for extra spending or tax cuts.

The growth in poverty

With incomes of the poor not keeping pace with inflation, many people are facing real hardship. While the Spring Statement will provide a small degree of support to the poor through cuts in fuel duty and the rise in the NI threshold, the measures are poorly targeted. Rather than cutting fuel duty by 5p, a move that is regressive, removing or reducing the 5% VAT on gas and electricity would have been a progressive move.

Benefits, such as Universal Credit and the State Pension, are uprated each April in line with inflation the previous September. When inflation is rising, this means that benefits will go up by less than the current rate of inflation. This April, benefits will rise by last September’s annual inflation rate of 3.1% – considerably below the current inflation rate of 6.2% and the forecast rate for this year of 7.4%. This will push many benefit recipients deeper into poverty.

One measure rejected by Rishi Sunak is to impose a temporary windfall tax on oil companies, which have profited from the higher global oil prices. Such taxes are used in Norway and are currently being considered by the EU. Tax revenues from such a windfall tax could be used to fund benefit increases or tax reductions elsewhere and these measures could be targeted on the poor.

Rise in the cost of living
Part 1: What are the distributional consequences?

Households are expected to see further rises in the cost of living after the annual inflation rate climbed for a 13th month to its highest point in almost 30 years. This will put further pressure on already stretched household budgets. The increase reflects a bounceback in demand for goods and services after lockdowns, when prices fell sharply. It also reflects the impact of supply-chain disruptions as Covid-19 hit factory production and global trade.

The biggest concern, however, is the impact it will have on those already hard-pressed families across the UK. According to official figures, prices are rising at similar rates for richer and poorer households. However, household income levels will determine personal experiences of inflation. Poorer households find it harder to cope than richer families as essentials, such as energy and food, form a larger proportion of their shopping basket than discretionary items. On average the lowest-income families spend twice as much proportionately on food and housing bills as the richest. So low-income households, if they are already spending mainly on essentials, will struggle to find where to cut back as prices rise.

Latest Inflation figures

Latest figures from the ONS show that the Consumer Prices Index (CPI) rose by 5.5% in the year to January 2022, with further increases in the rate expected over the next couple of months. In measuring inflation, the ONS takes a so-called ‘basket of goods, which is frequently updated to reflect changes in spending patterns. For example, in 2021, hand sanitiser and men’s loungewear bottoms were added, but sandwiches bought at work were removed.

Annual CPI inflation is announced each month, showing how much the weighted average of these prices has risen since the same date last year. The weighted average is expressed as an index, with the index set at 100 in the base year, which is currently 2015.

Consumers would not normally notice price rises from month to month. However, prices are now rising so quickly that it is clear for everyone to see. What is more, average pay is not keeping up. There are workers in a few sectors, such as lorry drivers, who are in high demand, and therefore their wages are rising faster than prices. But the majority of workers won’t see such increases in pay. In the 12 months to January, prices rose by 5.5% on average, but regular pay, excluding bonuses, on average rose by only 4.7%, meaning that they fell by 0.8% in real terms.

The Bank of England has warned that CPI inflation could rise to 7% this year and some economists are forecasting that it could be almost 8% in April.

Why are costs rising?

From the weekly food shop, to filling up cars, to heating our homes, the cost of living is rising sharply around the world. Global inflation is at its highest since 2008. Some of the reasons why include:

  • Rising energy and petrol prices
    Oil prices slumped at the start of the pandemic, but demand has rocketed back since, and oil prices have hit a seven-year high. The price of gas has also shot up, leaving people around the world with eye-watering central heating bills. Home energy bills in the UK are set to rise by 54% in April when Ofgem, the energy regulator, raises the price cap.
  • Goods shortages
    During the pandemic, prices of everyday consumer goods increased. Consumers spent more on household goods and home improvements because they were stuck at home, couldn’t go out to eat or go on holiday. Manufacturers in places such as Asia have struggled to keep up with the demand. This has led to shortages of materials such as plastic, concrete and steel, driving up prices. Timber cost as much as 80% more than usual in 2021 in the UK.
  • Shipping costs
    Global shipping companies have been overwhelmed by surging demand after the pandemic and have responded by raising shipping charges. Retailers are now having to pay a lot more to get goods into stores. These prices are now being passed on to consumers. Air freight fees have also increased, having been made worse by a lorry driver shortage in Europe.
  • Rising wages
    During the pandemic many people changed jobs, or even quit the workforce – a problem exacerbated in the UK by Brexit as many European workers returned to their home countries. Firms are now having problems recruiting staff such as drivers, food processors and restaurant waiters. This has resulted in companies putting up wages to attract and retain staff. Those extra costs to employers are again being passed on to consumers.
  • Extreme weather impact
    Extreme weather in many parts of the world has contributed to inflation. Global oil supplies took a hit from hurricanes which damaged US oil infrastructure. Fierce storms in Texas also worsened the problems in meeting the demand for microchips. The cost of coffee has also jumped after Brazil had a poor harvest following its most severe drought in almost a century.
  • Trade barriers
    More costly imports are also contributing to higher prices. New post-Brexit trading rules are estimated to have reduced imports from the EU to the UK by about a quarter in the first half of 2021. In the USA, import tariffs on Chinese goods have almost entirely been passed on to US customers in the form of higher prices. Chinese telecoms giant Huawei said last year that sanctions imposed on the company by the USA in 2019 were affecting US suppliers and global customers.
  • The end of pandemic support
    Governments are ending the support given to businesses during the pandemic. Public spending and borrowing increased across the world leading to tax rises. This has contributed to rises in the cost-of-living, while most people’s wages have lagged behind.

Main concerns for the UK inflation

With rapidly rising prices, the economic decisions people will have to make are much harder. The main concerns for UK households include increases in energy costs, food prices, rent and interest rates on borrowing. All of these concerns come at a time when the government prepares to increase national insurance contributions for workers in April. There has been some pressure from MPs to scrap the tax rise so as to ease the pressure on living costs. It can be argued that there are fairer ways to increase taxes than through national insurance. However, the plan is relatively progressive, and scrapping the rise could be a badly targeted way of helping the poorest households with their energy bills.

Energy Bills
Electricity and gas bills for a typical household are expected to increase on average by £693 a year in April, which, as we have seen, is a 54% increase. Around 18 million households on standard tariffs will see an average increase from £1277 to £1971 per year. And around 4.5 million prepayment customers will see an average increase of £708 – from £1309 to £2017. Energy bills won’t rise immediately for customers on fixed rates, but many are likely to see a significant increase when their deal ends.

Bills are going up because the energy price cap is being raised. The energy price cap is an example of a maximum price being imposed on the market; it is the maximum price suppliers in England, Wales and Scotland can charge households for their energy. Energy firms can increase bills by 54% when the new cap is introduced in April. The price cap is currently reviewed every 6 months and it is expected that that prices will rise again in October.

Energy price rises are likely to hit Britain’s poorest households the hardest as they spend proportionately more of their income on energy, a problem exacerbated by many living in poorly insulated homes. More people are thus expected to find themselves facing fuel poverty. This means that they spend a disproportionate amount of their income on energy and cannot afford to heat their homes adequately. According to the Resolution Foundation, the poorest will see their energy spend rise from 8.5% to 12% of their total household budget, three times the percentage for the richest.

The way fuel poverty is measured varies around the UK. In Scotland, a household is in fuel poverty if more than 10% of its income is spent on fuel and its remaining income isn’t enough to maintain an adequate standard of living. It is expected that the number of homes facing ‘fuel stress’ across the UK will treble to 6.3 million after April. It will, however, have the greatest impact on pensioners, people in local authority housing and low-income single-adult households who on average could be forced to spend over 50% of their income on gas and electricity. The Resolution Foundation thinktank has warned that UK households are facing a ‘cost of living catastrophe’.

Food
Low-income households also spend a larger proportion than average on food and will therefore be relatively more affected by increases in food prices. Food and non-alcoholic drink prices were up by 4.2% in the year to December 2021. The Monetary Policy Committee has stated that food price inflation is expected to increase in coming months, given higher input costs. It has been estimated by the thinktank, Food Foundation, that 4.7m Britons, equivalent to 8.8% of the population, are struggling to feed themselves and are regularly going a day without eating.

Supermarkets have also raised their concerns about future increases. Tesco’s chairman John Allan has predicted that the worst is yet to come, pointing to 5% as a likely figure for food price inflation by the spring. He cited high energy prices, both for Tesco and its suppliers, as a key factor behind the expected rise.

It has been observed that the Smart Price, Basics and Value range products offered by supermarkets as lower-cost alternatives are stealthily being extinguished from the shelves. This is leaving shoppers with no choice but to ‘level up’ to the supermarkets’ own better-quality branded goods – usually in smaller quantities at larger prices. The managing director of Iceland, Richard Walker, has stated that his stores are not losing customers to other competitors or to better offers, but to food banks and to hunger. This is a highly concerning statement given that 2.5m citizens were forced by an array of desperate circumstances to use food banks over the past year.

Rent
Private rents are also rising at their fastest rate in five years, intensifying the increase in the cost of living for millions of households. Data from the ONS reveal that the average cost of renting in the UK rose by 2% in 2021. This was the largest annual increase since 2017. The East Midlands had the biggest increase in average rental prices, with tenants paying 3.6% more than a year earlier. However, due to falling demand for city flats during lockdown, as people favoured working from home, London had the smallest increase at 0.1%. Nevertheless, as Covid restrictions are removed, renters, including office workers and students, are now returning back to cities. This is now pushing up rental prices with demand outpacing supply.

The property website Zoopla found newly advertised rental prices were rising much faster across the UK. It said the average rent jumped 8.3% in the final three months of 2021 to £969 a month. This increase in rental prices, combined with the general rise in prices will place additional pressure on the government to increase support for vulnerable families. The housing charity, Shelter, has reported an increase in people who are struggling to pay their rent and even pay their electricity. With Covid-era protections having ended, if people struggle to pay, they are faced with eviction or even homelessness. There are calls for the government to support such people by reversing welfare cuts.

Insurer, Legal & General, has announced an additional investment over the next 5 years of £2.5bn on its ‘build to rent’ schemes. The aim is to provide more than 7000 purpose-built rental homes in UK towns and cities. L&G claims that the additional homes are part of the solution to the rental problem, with rent increases being capped at 5% for five years. However, sceptics claim the company is simply trying to cash in on the booming market and there are calls for further government action. The Joseph Rowntree Foundation claim that renters will struggle as rents in some areas have risen as much as 8%. Despite this, housing benefit has been frozen for two years and therefore there are calls for government to urgently relink housing benefit to the real cost of renting.

JIT or illegit?

With the bounce-back from the pandemic, many countries have experienced supply-chain problems. For example, the shortage of lorry drivers in the UK and elsewhere (see the blog Why is there a driver shortage in the UK?) has led to empty shelves, fuel shortages and rising prices. The problem has been exacerbated by a lack of stock holding. Holding minimum stocks has been part of the modern system of ‘just-in-time’ (JIT) supply-chain management.

JIT involves involves highly integrated and sophisticated supply chains. Goods are delivered to factories, warehouses and shops as they are needed – just in time. Provided firms can be sure that they will get their deliveries on time, they can hold minimum stocks. This enables them to cut down on warehousing and its associated costs. The just-in-time approach to supply-chain management was developed in the 1950s in Japan and since the 1980s has been increasingly adopted around the world, helped more recently by sophisticated ordering and tracking software.

If supply chains become unreliable, however, JIT can lead to serious disruptions. A hold-up in one part of the chain will have a ripple effect along the whole chain because there is little or no slack in the system. When the large container ship, the Ever Given, en route from Malaysia to Felixtowe, was wedged in the Suez canal for six days in March this year, the blockage caused shipping to be backed up. By day six, 367 container ships were waiting to transit the canal. The disruption to supply cost some £730m.

JIT works well when sources of supply and logistics are reliable and when demand is predictable. The pandemic is causing many logistics and warehousing managers to consider building a degree of slack into their systems. This might involve companies having alternative suppliers they can call on, building in more spare capacity and having their own fleet of lorries or warehousing facilities that can be hired out when not needed but can be relied on at times of high demand.

When the ‘bounce back’ subsides, so may the current supply chain bottlenecks. But the rethinking that has been generated by the current problems may see new patterns emerge that make supply chains more flexible without becoming more expensive.
