In a post at the end of 2019, 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.

In New Zealand, Unilever has begun a one-year experiment to allow all 81 of its employees to work one day less each week and no more hours per day. This, it argues, might boost productivity and improve employees’ work-life balance.

The biggest experiment so far has been in Iceland. From 2015 to 2019 more than 2500 people took part in a pilot programme (about 1 per cent of Iceland’s working population). This involved reducing the working week to four days and reducing hours worked from 40 hours per week to 35 or 36 hours with no reduction in weekly pay.

Analysis of the results of the trial, published in July 2021, showed that output remained the same or improved in the majority of workplaces.

As a result of agreements struck with unions since the end of the pilot programme, 86% of Iceland’s workforce have either moved to shorter hours for the same pay or will gain the right to do so.

Many companies and public-sector employers around the world are considering reducing hours or days worked. With working patterns having changed for many employees during the pandemic, employers may now be more open to rethinking ways of deploying their workforce more productively. And this may involve rethinking worker motivation and welfare.

House prices are soaring throughout the world, making them unaffordable for many first-time buyers. In the UK, for example, according to the Nationwide, the annual house price increase was 13.4% in 2021 Q2. In the USA, house prices are rising by over 23% per annum.

The reason for this rampant house price inflation is that demand is rising much faster than supply. What is more, with inelastic supply in the short term, a given percentage rise in demand leads to a larger percentage increase in prices.

Reasons for rapidly rising house prices

But why has demand risen so rapidly? One major reason is that central banks have engaged in massive quantitative easing. This has driven down interest rates to historic lows and has led to huge asset purchases. Mortgage lenders, awash with money, have been able to increase the ratio of lending to income. Borrowing by house purchasers, encouraged by low interest rates and easy access to mortgages, has thus increased rapidly.

Another reason for the increased demand is that economies are beginning to recover from the COVID-induced recessions. This makes people more confident about their future financial positions and more willing to take on increased mortgage debt. Another reason is that, with increased working from home, people are looking for larger houses where rooms can be used as studies. Another is that, with less spending during the lockdowns, people have built up savings, which can be used to buy larger homes.

Some countries have deliberately boosted demand by fiscal measures. In the UK, the government introduced a stamp duty ‘holiday’. Previously a 3% ‘stamp duty’ tax was applied to purchases over £125 000. Under the holiday scheme, the rate would only apply to purchases over £500 000 until 30 June 2021 and then to purchases over £250 000 until 30 September 2021. This massively boosted demand, especially as the deadlines approached. In the USA, there are various schemes at federal and state level to support first-time buyers, including low-interest loans and vouchers. Supporting demand is counterproductive if it merely leads to higher prices and thus does not make it easier for people to buy.

Speculation has played a major part too, with many potential purchasers keen to buy before prices rise further. On the supply side, some vendors have held back hoping to get a higher price by waiting. Gazumping has returned. This is where vendors accept a new higher offer even though they have already accepted a previous lower one.

Effects of higher house prices

Higher house prices have had a knock-on effect on rents, which have also soared. This has encouraged house purchases for rent both by individuals and by property investment companies. The effect of rapidly rising house prices and rents has been to increase the divide in society between property owners and those unable to afford to buy and forced to rent.

Increased housing wealth is likely to lead to greater housing equity withdrawal. This is where people draw on some of their equity in order to finance increased consumer spending, thereby boosting aggregate demand and possibly inflation.

Will the house price boom end soon?

One scenario is that there will be a gradual slowdown in house price increases as quantitative easing is tapered off and as support measures, such as the UK’s stamp duty holiday, are unwound.

There is a real possibility, however, that there will be a more severe correction, with house prices actually falling. This could be triggered by central banks raising interest rates in response to higher inflation caused by the recovery and by higher commodity prices. In the UK, labour shortages brought about by Brexit could make the inflationary problem worse. With high levels of mortgage debt, even a half percentage point rise in mortgage interest rates could have a severe effect on demand. Falling house prices will then be compounded by speculation, with buyers holding off and sellers rushing to sell.

  2. Under what circumstances might tax relief help or not help first-time buyers?

  5. Under what circumstances would a sudden house price correction be more likely?
  6. Write a critique of housing policy in the light of growing inter-generational inequality of wealth.

Boeing and Airbus have called a truce in their 17-year battle over subsidies. During this period, both have accused each other of unfair government subsidies to their respective plane makers.

The long-running trade dispute

In October 2004, the USA requested the establishment of a WTO panel to consider whether Airbus was providing unfair subsidies to develop its new super-jumbo – the A380. This provoked a counter-request by Airbus, claiming unfair subsidies of $27.3 billion for Boeing by the US government since 1992. In July 2005, two panels were set up to deal with the two sets of allegations.

In June 2010, the WTO panel circulated its findings on Boeing’s case against Airbus. It found Airbus guilty of using some illegal subsidies to win contracts through predatory pricing, but dismissed several of Boeing’s claims because many of the subsidies were reimbursable at commercial rates of interest. However, some of the ‘launch aid’ for research and development was given at below market rates and so violated WTO rules. The report evoked appeal and counter-appeal from both sides, but the WTO’s Appellate Body reported in May 2011 upholding the case that ‘certain subsidies’ provided by the EU and member states were incompatible with WTO rules. In June 2011, the EU accepted the findings.

In March 2011, the WTO panel circulated its findings on Airbus’s case against Boeing. The EU claimed that ten specific measures amounted to subsidies to Boeing, which were inconsistent with the WTO’s rules on subsidies (the SCM agreement). It upheld three of ten alleged breaches, including subsidies between 1989 and 2006 of at least $5.3 billion. These subsidies were adjudged to have resulted in adverse effects to the EU’s interests, specifically in lost sales, especially to third-country markets, and in significantly suppressing the price at which Airbus was able to sell its aircraft.

But these rulings were not the end of the matter. Various appeals and counter-appeals were lodged by both sides with varying degrees of success. Also the disputes extended to other wide-bodied jets and to narrow-bodied ones too with claims by both sides of unfair subsidies and tax breaks.

On 9 June 2017 the WTO’s compliance panel rejected several EU claims that the USA had failed to withdraw all illegal subsidies to Boeing. However, it also found that the USA had not complied with an earlier ruling to abolish illegal tax breaks. Both sides claimed victory. Airbus claimed that the ruling had seen the WTO condemn non-compliance and new subsidies. In particular, it focused on the WTO ruling that Washington State subsidies had resulted in a significant loss of sales for Airbus. On the other hand, a Boeing press release spoke of a US win in a major WTO compliance ruling. Boeing claimed that that ruling meant that the United States had complied with ‘virtually all’ of the WTO’s decisions in the counter-case that the EU had filed against the USA in 2006.

On 27 June 2017, as expected, the EU challenged the WTO decision. This meant that the EU’s case would go back to the WTO’s appellate body, which was still considering a separate US case over state aid to Airbus.

On 15 May 2018, the WTO ruled that Airbus did not use unfair subsidies for narrow-bodied jets, such as the A320, which competes with the 737, but did for wide-bodied jets. The EU said that it would comply with the WTO ruling over the support for wide-bodied jets.

In 2019, the WTO ruled that the EU had illegally provided support to Airbus. The USA responded with tariffs of up to $7.5bn on a range of goods imported from the EU. In a parallel case, the WTO ruled that the US benefits to Boeing also violated trade rules, authorising the EU to impose tariffs on US imports worth roughly $4bn. Then in March 2020, the USA imposed a 15% tariff on Airbus aircraft.

The truce

Agreement was reached on 15 June 2021 in trade talks between the USA and the EU in Brussels. Both sides recognised that the dispute had been a negative-sum game, with both sides losing. It was thus agreed to suspend for five years all tariffs on aircraft and on a range of other goods, such as EU cheese and wine and US tobacco and spirits. The agreement did not include ending EU tariffs on US steel, however.

It was also agreed to work on an overarching agreement on subsidies, which would allow fair support by governments on both sides, and to co-operate in finding ways to counter unfair state investment in aircraft by China. US Trade Representative Katherine Tai said that the agreement ‘includes a commitment for concrete joint collaboration to confront the threat from China’s ambitions to build an aircraft sector on non-market practices’. China’s state-sponsored aerospace manufacturer, the Commercial Aircraft Corporation of China, or Comac, sees its C919, now in late stages of development, as a direct rival to the Airbus A320neo and the Boeing 737 Max.

To work out the details of US-EU collaboration, a working group will be set up. It will consider ways of ensuring that finance is provided on market terms, that R&D funding is transparent and that support given to aircraft manufactures will be equivalent by each side and will avoid harming the other side. It will consider just how the two sides can co-operate to address unfair competition from elsewhere.

Two days later, an almost identically worded deal was reached between the USA and the UK to end tariffs on a range of goods and join the EU-USA co-operation on aircraft manufacture.

The effects of the Brexit trade deal are becoming clearer as new data are released. Figures for UK food imports and exports from and to the EU for the first quarter of 2021 have been published by the Food and Drink Federation. These show a 46.6% fall in UK food and drink exports to the EU in Q1 2021 when compared with Q1 2020, and a 55.1% fall when compared with Q1 2019 (before COVID).

The dairy sector has been the hardest hit, with exports of milk and cream to the EU down by more than 90% and exports of cheese down by 67% compared with Q1 2020. Other hard-hit sectors have been soft drinks, fish, potatoes and chicken. (Click here for a PowerPoint of the following chart.)

The Brexit trade deal did not involve the imposition of tariffs on exports and imports. However, with the UK having left the EU single market, there are now many regulatory checks and a considerable amount of paperwork to be completed for each consignment of exports. These frictions are slowing down trade and adding to costs. Although food and drink exports are beginning to recover somewhat, the delays while formalities are completed will have a lasting dampening effect on exports to the EU, especially in the case of perishable goods, such as meat and fish.

Also, farming has been badly affected by labour shortages, with many EU citizens returning to the EU. For example, according to the British Poultry Council (BPC), 10 per cent fewer chickens had been produced since Easter because of worker shortages. Across meat processing generally, similar shortfalls are being recorded because of a lack of labour.



  1. Find out how exports to the EU from sectors other than food and drink have fared since January this year.
  2. What are rules of origin? Why are they less likely to apply to food exports to the EU than to manufactured exports?
  3. Would you describe the Brexit trade deal (the EU-UK Trade and Cooperation Agreement) as a ‘free-trade’ deal? Explain.
  4. What are the particular difficulties for the food and drink sector in the Trade and Cooperation Agreement?
  5. Find out which parts of the food and drink sector have been particularly affected by labour shortages.

One of the major economic concerns about the COVID-19 pandemic has been the likely long-term scarring effects on economies from bankruptcies, a decline in investment, lower spending on research and development, a loss of skills, discouragement of workers, disruption to education, etc. The result would be a decline in potential output or, at best, a slower growth. These persistent effects are known as ‘hysteresis’ – an effect that persists after the original cause has disappeared.

In a speech by Dave Ramsden, the Bank of England’s Deputy Governor for Markets & Banking, he argued that, according to MPC estimates, the pandemic will have caused a loss of potential output of 1.75%. This shortfall may seem small at first sight, so does it matter? According to Ramsden:

The answer is definitely yes for two reasons. First, a 1¾% shortfall as a share of annual GDP for the UK … represents roughly £39 billion – for context, that’s about half of the education budget. And second, that 1¾% represents a permanent shortfall, or at least a very persistent one, on top of the impact of the immediate downturn. If you lose 1¾% of GDP every year for ten years, then in total you have lost 17.5% of one year’s GDP, or around £390bn in 2019 terms

However, as the IMF blog linked below argues, there may be positive supply-side effects which outweigh these scarring effects, causing a net rise in potential GDP growth. There are two possible reasons for this.

The first is that the pandemic may have hastened the process of digitalisation and automation. Examples include ‘video conferencing and file sharing applications to drones and data-mining technologies’. According to evidence from a sample of 15 countries cited in the blog, a 10% rise in such intangible capital investment is associated with about a 4½% rise in labour productivity. ‘As COVID-19 recedes, the firms which invested in intangible assets, such as digital technologies and patents may see higher productivity as a result.’

The second is a reallocation of workers and capital to more productive sectors. Firms in some sectors, such as leisure, hospitality and retail, have relatively low labour productivity. Many parts of these industries have declined during the pandemic, especially those with high labour intensity. At the same time, there has been a rise in employment in firms where output per worker is higher. Such sectors include e-commerce and those where remote working is possible. The greater the reallocation from low labour-productivity to high labour-productivity sectors, the more will overall labour productivity rise and hence the more will potential output increase.

The size of these two effects will depend to a large extent on expectations, incentives and government policy. The blog cites four types of policy that can help investment and reallocation.

  • Improved insolvency and restructuring procedures to enable capital in failed firms to be reallocated to sectors with potential for growth.
  • Promoting competition to enable the exit and entry of firms into expanding sectors and to prevent powerful firms from blocking the process.
  • Refocusing policy from retaining labour in existing jobs to reskilling workers for new jobs, thereby improving labour mobility from declining to expanding sectors.
  • Addressing financial bottlenecks, so as to ensure adequate access to financing for viable firms.

Whether there will be a net increase or decrease in productivity from the pandemic very much depends on the extent to which firms and workers are able and willing to take advantage of new opportunities and the extent to which government supports investment in and reallocation to high-productivity sectors.
