In various blogs, we’ve looked at the UK’s low productivity growth, both relative to other countries and relative to the pre-1998 financial crisis (see, for example, The UK productivity puzzle and Productivity should we be optimistic?). Productivity is what drives long-term economic growth as it determines potential GDP. If long-term growth is seen as desirable, then a fall in productivity represents a serious economic problem.
Recent data suggest that the problem, if anything, is worse than previously thought and does not seem to be getting better. Productivity is now some 21% below what it would have been had productivity growth continued at the rate experienced in the years before the financial crisis (see second chart below).
In its latest productivity statistics, the ONS reports that labour productivity (in terms of output per hour worked) fell by 0.1% in the second quarter of 2017. This follows a fall of 0.5% in quarter 1. Over the whole year to 2017 Q2, productivity fell by 0.3%.
Most other major developed countries have much higher productivity than the UK. In 2016, Italy’s productivity was 9.9% higher than the UK’s; the USA’s was 27.9%, France’s was 28.7% and Germany’s was 34.5% higher. What is more, their productivity has grown faster (see chart).
But what of the future? The Office for Budget responsibility publishes forecasts for productivity growth, but has consistently overestimated it. After predicting several times in the past that UK productivity growth would rise towards its pre-financial crisis trend of around 2% per year, in its October 2017 Forecast evaluation Report it recognises that this was too optimisitic and revises downwards its forecasts for productivity growth for 2017 and beyond.
As the period of historically weak productivity growth lengthens, it seems less plausible to assume that potential and actual productivity growth will recover over the medium term to the extent assumed in our most recent forecasts. Over the past five years, growth in output per hour has averaged 0.2 per cent. This looks set to be a better guide to productivity growth in 2017 than our March forecast of 1.6 per cent.
Looking further ahead, it no longer seems central to assume that productivity growth will recover to the 1.8 per cent we assumed in March 2017 within five years.
But why has productivity growth not returned to pre-crisis levels? There are five possible explanations.
The first is that there has been labour hoarding. But with companies hiring more workers, this is unlikely still to be true for most employers.
The second is that very low interest rates have allowed some low-productivity companies to survive, which might otherwise have been driven out of business.
The third is a reluctance of banks to lend for investment. After the financial crisis this was driven by the need for them to repair their balance sheets. Today, it may simply be greater risk aversion than before the financial crisis, especially with the uncertainties surrounding Brexit.
The fourth is a fall in firms’ desire to invest. Although investment has recovered somewhat from the years directly following the financial crisis, it is still lower than might be expected in an economy that is no longer is recession. Indeed, there has been a much slower investment recovery than occurred after previous recessions.
The fifth is greater flexibility in the labour market, which has subdued wages and has allowed firms to respond to higher demand by taking on more relatively low-productivity workers rather than having to invest in human capital or technology.
Whatever the explanation, the solution is for more investment in both technology and in physical and human capital, whether by the private or the public sector. The question is how to stimulate such investment.

In the last blog post, As UK inflation rises, so real wages begin to fall, we showed how the rise in inflation following the Brexit vote is causing real wages in the UK to fall once more, after a few months of modest rises, which were largely due to very low price inflation. But how does this compare with other OECD countries?
In an article by Rui Costa and Stephen Machin from the LSE, the authors show how, from the start of the financial crisis in 2007 to 2015 (the latest year for which figures are available), real hourly wages fell further in the UK than in all the other 27 OECD countries, except Greece (see the chart below, which is Figure 5 from their article). 
Indeed, only in Greece, the UK and Portugal were real wages lower in 2015 than in 2007.
The authors examine a number of aspects of real wages in the UK, including the rise in self employment, differences by age and sex, and for different percentiles in the income distribution. They also look at how family incomes have suffered less than real wages, thanks to the tax and benefit system.
The authors also look at what the different political parties have been saying about the issues during their election campaigns and what they plan to do to address the problem of falling, or only slowly rising, real wages.

The UK Chancellor of the Exchequer, Philip Hammond, announced in the Budget this week that national insurance contributions (NICs) for self-employed people will rise from 9% to 11% by 2019. These are known as ‘Class 4’ NICs. The average self-employed person will pay around £240 more per year, but those on incomes over £45,000 will pay £777 more per year. Many of the people affected will be those working in the so-called ‘gig economy’. This sector has been growing rapidly in recent years and now has over 4 million people working in it.
Workers in the gig economy are self employed, but are often contracted to an employer. They are paid by the job (or ‘gig’: like musicians), rather than being paid a wage. Much of the work is temporary, although many in the gig economy, such as taxi drivers and delivery people stick with the same job. The gig economy is just one manifestation of the growing flexibility of labour markets, which have also seen a rise in temporary employment, part-time employment and zero-hour contracts.
Working in the gig economy provides a number of benefits for workers. Workers have greater flexibility in their choice of hours and many work wholly or partly from home. Many do several ‘gigs’ simultaneously, which gives variety and interest.
In terms of economic theory, this flexibility gives workers a greater opportunity to work the optimal amount of time. This optimum involves working up to the point where the marginal benefit from work, in terms of pay and enjoyment, equals the marginal cost, in terms of effort and sacrificed leisure.
For firms using people from the gig economy, it has a number of advantages. They are generally cheaper to employ, as they do not need to be paid sick pay, holiday pay or redundancy; they are not entitled to parental leave; there are no employers’ national insurance contributions to pay (which are at a rate of 13.8% for employers); the minimum wage does not apply to such workers as they are not paid a ‘wage’. Also the firm using such workers has greater flexibility in determining how much work individuals should do: it chooses the amount of service it buys in a similar way that consumers decide how much to buy.
Many of these advantages to firms are disadvantages to the workers in the gig economy. Many have little bargaining power, whereas many firms using their services do. It is not surprising then that the Chancellor’s announcement of a 2 percentage point rise in NICs for such people has met with such dismay by the people affected. They will still pay less than employed people, but they claim that this is now not enough to compensate for the lack of benefits they receive from the state or from the firms paying for their services.
Some of the workers in the gig economy can be seen as budding entrepreneurs. If you have a specialist skill, you may use working in the gig economy as the route to setting up your own business and employing other people. A self-employed plumber may set up a plumbing company; a management consultant may set up a management consultancy agency. Another criticism of the rise in Class 4 NICs is that this will discourage such budding entrepreneurs and have longer-term adverse supply-side effects on the economy.
As far as the government is concerned, there is a worry about people moving from employment to self-employment as it tends to reduce tax revenues. Not only will considerably less NIC be paid by previous employers, but the scope for tax evasion is greater in self-employment. There is thus a trade-off between the extra output and small-scale investment that self-employment might bring and the lower NIC/tax revenue for the government.

The UK benefits system is complex and this is just one reason why some people fall through the safety net. There are criticisms that it doesn’t reward work and doesn’t provide sufficient incentives to move off benefits and into work. One rather radical policy that has been discussed in numerous countries is the idea of a ‘Basic Income’.
The Basic Income or Citizen’s Income is a policy where individuals receive a regular payment from the government, essentially for doing nothing. The income is paid and aims to cover basic living costs and on top of this, individuals can then work, earn income and pay tax on it. Experiments of this policy are already in place and over the next few years, we may see many more being trialled and much discussion of the possibility of implementing this in the UK. We tend to be fairly risk averse when it comes to radical policies and so while we may see discussion of it in the UK, I imagine we’ll want to see the relative success of the policy in other countries first!
There are many variations of the scheme and lots of questions that need addressing. Will it encourage people to work more or less? Might it reduce the stigma of claiming benefits, if this is a basic income that everyone receives? Does it simplify the system and hence provide more people with a basic income thus targeting poverty?
Some proposals have this payment as a universal one – non means tested and not conditional on anything. 
Other proposals, including one in Finland, sees just the unemployed receive the benefit and appears to be a social experiment to see if such a policy discourages the unemployed from taking jobs. Traditionally individuals receive a benefit if they are out of work, but this benefit can be cut (in some cases quite substantially) if they begin to work. This creates a disincentive to supply labour. However, under the basic income scheme, those who moved into work would continue to receive the basic income payment and hence the disincentive effect is removed. The policy thus creates a basic level of economic security. As Howard Reed and Stewart Lansley argue, it would offer:
“…financial independence and freedom of choice for individuals between work and leisure, education and caring, while recognising the huge value of unpaid work”.
There isn’t universal support for this type of scheme and many remain very cautious about such a radical policy and how the incentives will work. Key questions focus around the marginal rate of income tax that might be needed to finance such a policy. Furthermore, there is discussion about the equity of the policy if it is universal and hence non means-tested.
In Switzerland, the policy was put to a public referendum and it was rejected, with 75% of voters voting against such a policy. However, with changes in the structure of economies and, in many countries, technological change increasingly leading to automation, some argue that such a system will help to protect people. Lord Skidelsky, Professor of Political Economy at Warwick University said:
“Credible estimates suggest it will be technically possible to automate between a quarter and a third of all current jobs in the western world within 20 years … It [Basic Income] would ensure the benefits of automation were shared by the many, not just the few.”
Basic Income or Citizen’s Income is certainly something we are likely to hear a lot about during 2017. Whether or not the time has come for implementation is another matter, but it’s a good idea now to look into both sides and the relative success of the upcoming trials around the world.

Many countries have experienced soaring house prices in recent years. To find out why, you need to look at demand and supply.
Low mortgage interest rates and more relaxed lending rules in the last couple of years have stimulated demand. In some countries, such as the UK, demand has been further boosted by governments providing increased help to buyers. In others, various tax breaks are given to house purchasers.
Typically the rise in demand has not been matched by an equivalent rise in supply. Social house building has slowed in many countries and building for private purchase has often be hampered by difficulties in obtaining appropriate land or getting planning permission.
The articles linked below look at the situation in Australia. Here too house prices have been soaring. Over the past 30 years they have grown by 7.25% per year – way above the growth in incomes. As the second article below states:
So expensive are homes becoming that the share of median household income devoted to mortgage payments for Australians aged 35 to 44 has more than doubled in 30 years. Incredibly, it’s happened at a time when mortgage rates have slid to their lowest on record.
But why? Again, to understand this it is necessary to look at demand and supply.
Strong population growth combined with easy availability of mortgage loans, low interest rates and tax breaks for both owner occupiers and property investors have stoked demand, while new building has lagged behind. As far as investors are concerned, any shortfall of rental income over mortgage payments (known as negative gearing) can be offset against tax – and then there is still the capital gain to be made from any increase in the property’s price.
But in some Australian towns and cities, price rises have started to slow down or even fall. This may be due to a fall in demand. For example, in Perth, the ending of the commodity boom has led to a fall in demand for labour in the mining areas; mine workers often live in Perth and fly up to the mining areas for shifts of a week or more. 
The fall in demand for labour has led to a fall in demand for housing.
House price changes are amplified by speculation. People rush to buy houses when they think house prices will rise, further pushing up prices. Landlords do the same. This speculation fuels the price rises. Speculation also amplifies price falls, with people with houses to sell keen to sell them quickly before prices fall further. Potential purchasers, including property investors, hold back, waiting for prices to fall.
