UK productivity growth remains well below levels recorded before the financial crisis, as Chart 1 illustrates. In fact, output per hour worked in 2016 Q3 was virtually the same as in 2007 Q4. What is more, as can be seen from Chart 2, UK productivity lags well behind its major competitors (except for Japan).
But why does UK productivity lag behind other countries 
and why has it grown so slowly since the financial crisis? In its July 2015 analysis, the ONS addressed this ‘productivity puzzle’.
Among the many reasons suggested are low levels of investment, the impact of the financial crisis on bank’s willingness to lend to new businesses, higher numbers of people working beyond normal retirement age as a result of population and pensions changes, and firms’ ability to retain staff because of low pay growth. While these and other factors may be relevant, they do not provide a complete explanation for the weakness in productivity.
The lack of investment in technology and lack of infrastructure investment have been key reasons for the sluggish growth in productivity. Many companies are prepared to continue using relatively labour-intensive techniques because wage growth has been so low and this reduces the incentive to invest in labour-saving technology.
Another factor has been long hours and, for many office workers, being constantly connected to their work, checking and responding to emails and messages away from the office. The Telegraph article below reports Ann Francke, chief executive of the Chartered Management Institute, as saying:
“This is having a deleterious effect on the health of managers, which has a direct impact on productivity. UK workers already have the longest hours in Europe and yet we’re less productive.”
Another problem has been ultra low interest rates, which have reduced the burden of debt for poor performing companies and has allowed them to survive. It may also have prevented finance from being reallocated to more dynamic companies which would like to develop new products and processes.
Another feature of UK productivity is the large differences between regions. This is illustrated in Chart 3. Productivity in London in 2015 (the latest full year for data) was 31.5% above the UK average, while that in Wales was 19.4% below.
This again reflects investment patterns and also the concentration of industries in particular locations. Thus London’s financial sector, a major part of London’s economy, has experienced relatively large increases in productivity and this has helped to push productivity growth in the capital well above other parts of the country.
Another factor, which again has a regional dimension, is the poor productivity performance of family-owned businesses, where ownership and management is passed down the generations within the family without bringing in external managerial expertise.
The government is very aware of the UK’s weak productivity performance. Its recently launched industrial policy is designed to address the problem. We look at that in a separate post.

Earlier this week FIFA, the world governing body of football, announced plans to expand the World Cup from 32 to 48 teams starting in 2026. It is fair to say that this has been met with mixed reactions, in part due to the politics and money involved. However, for an economist one particularly interesting question is how the change will affect the incentives of the teams taking part in the competition.
As a result of the change in the first stage of the competition, teams will be play the two other teams in their group. The best two teams in the group will then progress to the next round with the worst team going home. This is in contrast to the current format where the best two teams from a group of four go through to the next round.
Currently, in the final round of group matches all four of the teams in the group play simultaneously. However, an immediate implication of the new format is that this will no longer be the case. Instead, one of the teams will have finished their group matches before the other two teams play each other. This could have important implications for the incentives of the teams involved. To see this we can recall a very famous match played under similar circumstances between West Germany and Austria at the 1982 World Cup.
The results of the earlier group games meant that if West Germany beat Austria by one or two goals to nil both teams would progress to the next round. Any other result would mean that Algeria progressed at the expense of one of these two teams. The way in which the match played out was that West Germany scored early on and much of the rest of the game descended into farce. Both teams refused to attack or tackle their opponents, as they had no incentive to so (see here for some clips of the action, or lack of!).
There is no evidence to suggest that West Germany and Austria had come to a formal agreement to do this. Instead, the two teams appear to have simply had a mutual understanding that refraining from competing would be beneficial for both of them.
This is exactly what economists refer to as tacit collusion – a mutual understanding that refraining from competition and keeping prices high benefits all firms in the market. Much like the fans who had to sit through the farce of a game (you can hear the frustration of the crowd in the video clip linked to above), the end result is harm to consumers who have to pay the higher prices or go without the product.
For this reason governments use competition policy to try to stop situations arising in markets that make the possibility of tacit collusion more likely. One way in which this is done is by preventing mergers in markets where tacit collusion appears possible and would be facilitated by the reduction in the number of firms as a result of the merger. The equivalent for the World Cup would be preventing a change in the format of the competition.
An alternative approach is to tinker with the rules of the game in order to make collusion harder. FIFA seems to have some awareness of the possibility of doing this as it is suggesting that it may require all tied games to extra-time and then a penalty shoot-out in order to determine a winner. Clearly, this would go at least some way to alleviating concerns about tacit collusion in the final group matches because coordinating on a draw would no longer be possible. In a similar fashion, competition authorities can also intervene in markets to change the rules of the game (see for example the recent intervention in the UK cement industry).
Therefore, more generally, the World Cup example highlights the fact that variations in the structure of markets and the rules of the game can have significant effects on firms’ incentives and this can have important consequences for market outcomes. It will certainly be fascinating to see what rules are imposed for the 2026 World Cup and how the teams taking part respond.

The Competition and Markets Authority (CMA) has imposed a record fine of £84m on the American pharmaceutical manufacturing company Pfizer and of £5.2m on its UK distributor, Flynn Pharma. The CMA found that the companies charged unfair prices to the NHS for phenytoin sodium capsules, the anti-epilepsy drug.
The price was previously regulated, but Pfizer deliberately de-branded the drug in September 2012 and immediately raised the price to Flynn Pharma by between 780% and 1600%, which, in turn, raised the price to the NHS by nearly 2600%. This made the drug many times more expensive than in any other European country.
The cost to the NHS rose from around £2m per year to around £50m in 2013. Although other generic drugs are available, there would be serious health risks to patients forced to switch drugs. The NHS thus had no alternative to paying the higher price.
Pfizer claimed that the drug was loss-making before it was de-branded. However, the CMA calculated that this did not justify the size of the price increase; that the higher price enabled Pfizer to recover all these claimed losses within just two months.
The usual practice is for pharmaceutical companies to charge high prices for new drugs for a period of time to enable them to recover high research and development costs. Later, the drugs become available as generic drugs that other manufacturers can produce. The price then normally falls dramatically.
Phenytoin sodium was invented many years ago and there has been no recent innovation and no significant investment. But, unlike with many other drugs, there has been no switching by the NHS because of possible dangers to patients. This has given Pfizer and its distributor considerable market power. As the CMA states in its press release:
Epilepsy patients who are already taking phenytoin sodium capsules should not usually be switched to other products, including another manufacturer’s version of the product, due to the risk of loss of seizure control which can have serious health consequences. As a result, the NHS had no alternative to paying the increased prices for the drug.
In conclusion, the CMA found that “both companies have held a dominant position in their respective markets for the manufacture and supply of phenytoin sodium capsules and each has abused that dominant position by charging excessive and unfair prices”.

- Under what legislation did the CMA fine Pfizer and Flynn Pharma? What is the upper limit to the fine it is able to impose? Did it impose the maximum fine on Pfizer?
The UK government has finally given the go-ahead to build the new Hinkley C nuclear power station in Somerset. It will consist of two European pressurised reactors, a relatively new technology. No EPR plant has yet been completed, with the one in the most advanced stages of construction at Flamanville in France, having experienced many safety and construction problems. This is currently expected to be more than three times over budget and at least six years behind its original completion date of 2012.
The Hinkley C power station, first proposed in 2007, is currently estimated to cost £18 billion. This cost will be borne entirely by its builder, EDF, the French 85% state-owned company, and its Chinese partner, CGN. When up and running – currently estimated at 2025 – it is expected to produce around 7% of the UK’s electricity output.
On becoming Prime Minister in July 2016, Theresa May announced that the approval for the plant would be put on hold while further investigation of its costs, benefits, 
security concerns, technological issues and safeguards was conducted. This has now been completed and approval has been granted subject to new conditions. The main one is that the government “will be able to prevent the sale of EDF’s controlling stake prior to the completion of construction”. This will allow the government to prevent change of ownership during the construction phase. Thus, for example, EDF, would not be allowed to sell its share of Hinkley C to CGN, which currently has a one-third share in the project. EDF and CGN have accepted the new terms.
After Hinkley the government will have a ‘golden share’ in all future nuclear projects. “This will ensure that significant stakes cannot be sold without the Government’s knowledge or consent.”
In return for their full financing of the project, the government has guaranteed EDF and CGN a price of £92.50 per megawatt hour of electricity (in 2012 prices). This price will be borne by consumers. It will rise with inflation from now and over the first 35 years of the power station’s operation. It is expected that the Hinkley C will have a life of 60 years.
Critics point out that this guaranteed ‘strike price’ is more than double the current wholesale price of electricity and, with the price of renewables falling as technology improves, it will be an expensive way to meet the UK’s electricity needs and cut carbon emissions.
Those in favour argue that it is impossible to predict electricity prices into the distant future and that the certainty this plant will give is worth the high price by current standards.
To assess the desirability of the plant requires an assessment of its costs and benefits. In principle, this is a relatively simple process of identifying and measuring the costs and benefits, including external costs and benefits; discounting future costs and benefits to give them a present value; weighting them by their probability of occurrence; then calculating whether the net present value is positive or negative. A sensitivity analysis could also be conducted to show just how sensitive the net present value would be to changes in the value of specific costs or benefits.
In practice the process is far from simple – largely because of the huge uncertainty over specific costs and benefits. These include future wholesale electricity prices, unforeseen problems in construction and operation, and a range of political issues, such as pressure from various interest groups, and attitudes and actions of EDF and CGN and their respective governments, which will affect not only Hinkley C but other future power stations.
The articles look at the costs and benefits of this, the most expensive construction project ever in the UK, and possibly on Earth..

This time last year bookmakers Ladbrokes and Coral announced their intention to merge. This was closely followed by a merger between Betfair and Paddy Power. This wave of consolidation appears to have been partly motivated by the rise of online gambling, stricter regulation and increased taxation.
The UK Competition and Markets Authority (CMA) commenced an initial investigation into the Ladbrokes-Coral merger in late 2015 and, at the request of the merging parties, agreed to fast track the case to a detailed phase 2 investigation.
Despite the growth in the online market, the CMA’s investigation recognised the continued importance of high-street betting shops:
Although online betting has grown substantially in recent years, the evidence we’ve seen confirms that a significant proportion of customers still choose to bet in shops – and many will continue to do so after the merger.
The CMA identified almost 650 local markets where it believed there would be a substantial lessening of competition. It concluded that this could have both local and national effects:
Discounts and offers of free bets to individual customers are 2 of the ways betting shops respond to local competition which could be threatened by the merger. Such a widespread reduction in competition at the local level could also worsen those elements that are set centrally, such as odds and betting limits.
Therefore, earlier this week the CMA announced that before it is prepared to clear the merger, the parties must sell around 350 stores in order to preserve competition in the problem markets (many of these overlap so the number of store sales required is less than the number of problem markets). This divestment represents around 10% of the total number of stores currently owned by the two merging parties. It appears that rivals Betfred and Boylesports, plus a number of private equity investors, are already interested in purchasing the stores.
This may also not be the last consolidation in the industry with the struggling leading bookmaker William Hill apparently attracting merger interest from rival 888 in combination with a casino and bingo hall operator.
