The geographical immobility of labour in England – a social problem

Where you live in Great Britain can have a profound effect on your earning potential. According to a report published by the Social Mobility Commission, there is a growing geographical divide, with more affluent areas getting relatively richer, while ‘many other parts of the country are being left behind economically and hollowed out socially’.

The Commission uses a Social Mobility Index to rank the 324 local authorities in England. The index is a measure of the social mobility prospects for people from disadvantaged backgrounds. It is ‘made up of 16 key performance indicators spanning each major life stage’.

The index shows that children from disadvantaged backgrounds have lower educational attainment, poorer initial jobs and poorer prospects for advancement in the labour market. Often they are stuck in low paid jobs with little chance of getting on the housing ladder and fewer chances of moving away from the area.

The problem is not simply one of a North-South divide or one of inner cities versus the suburbs. Many inner-city areas have been regenerated, with high incomes and high social and geographical mobility. Other inner-city areas remain deprived.

The worst performing areas are remote rural or coastal areas and former industrial areas, where industries have closed. As the author of the report states in the Guardian article linked below:

These areas have fewer specialist teachers, fewer good schools, fewer good jobs and worse transport links. … Many of these areas have suffered from a lack of regeneration: few high-paying industries are located there, and they often exhibit relatively limited job opportunities and clusters of low pay.

The problem often exists within areas, with some streets exhibiting growing affluence, where the residents have high levels of social mobility, while other streets have poor housing and considerable levels of poverty and deprivation. Average incomes for such areas thus mask this type of growing divide within areas. Indeed, some of the richest areas have worse outcomes for disadvantaged children than generally poorer areas.

There are various regional and local multiplier effects that worsen the situation. Where people from disadvantaged backgrounds are successful, they tend to move away from the deprived areas to more affluent ones, thereby boosting the local economy in such areas and providing no stimulus to the deprived areas. And so the divide grows.

Policies, according to the report, need to focus public investment, and incentives for private investment, in deprived areas. They should not focus simply on whole regions. You can read the specific policy recommendations in the articles below.

Black Monday – 30 years on

Thirty years ago, on Monday 19 October 1987, stock markets around the world tumbled. The day has been dubbed ‘Black Monday’. Wall Street fell by 22% – its biggest ever one-day fall. The FTSE 100 fell by 10.8% and by a further 12.2% the next day.

The crash caught most people totally by surprise and has never been fully explained. The most likely cause was an excessive rise in the previous three years, when share prices more than doubled. This was combined with the lack of ‘circuit breakers’, which today would prevent excessive selling, and a ‘herd’ effect as people rushed to get out of shares before they fell any further, creating a massive wave of destabilising speculation.

Within a few weeks, share prices started rising again and within three years shares were once again trading at levels before Black Monday.

Looking back to the events of 30 years ago, the question many fund managers and others are asking is whether global stock markets are in for another dramatic downward correction. But there is no consensus of opinion about the answer.

Those predicting a downward correction – possibly dramatic – point to the fact that stock markets, apart from a dip in mid-2016, have experienced several years of growth, with yields now similar to those in 1987. Price/earnings ratios, at around 18, are high relative to historical averages.

What is more, the huge increases in money supply from quantitative easing, which helped to inflate share prices, are coming to an end. The USA ceased its programme three years ago and the ECB is considering winding down its programme.

Also, once a downward correction starts, destabilising speculation is likely to kick in, with people selling shares before they go any lower. This could be significantly aggravated by the rise of electronic markets with computerised high-frequency trading.

However, people predicting that there will be little or no downward correction, and even a continuing bull market, point to differences between now and 1987. First, the alternatives to shares look much less attractive than then. Bond yields and interest rates in banks (at close to zero), unlike in 1987, are much lower than the dividend yields on shares (at around 4%). Second, there are circuit breakers in stock markets that suspend dealing in cases of large falls.

But even if there is a downward correction, it will probably be relatively short-lived, with the upward trend in share prices continuing over the long term. If you look at the chart above, you can see this trend, but you can also see periods of falling share prices in the late 1990s/early 2000s and in the financial crisis of 2008–9. Looking back to 1987, it seems like a mere blip from the perspective of 30 years – but it certainly didn’t at the time.

UK low productivity growth – even worse than thought

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.

Falling UK real wages – comparison with other OECD countries

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 gig economy

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.

Basic Income: a step forward?

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.

The housing market: an Australian case study of demand and supply

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.

Going nuclear

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..

The UK gender wage gap

Women in the UK on average earn less per hour than men. According to the Annual Survey of Hours and Earnings, the mean hourly pay for women in 2015 was 17.5% less than that for men. This figure is for all employees, full and part time. As far as full-time employees is concerned, the gap was slightly smaller at 13.9%. Nevertheless, as you can see from Table 6 in the linked Excel file, these gaps have decreased in recent years – but only slightly.

A recent paper from the Institute for Fiscal Studies has disaggregated the figures to give a better picture of this wage gap. It finds that having children is a major contributing factor to the gap. It also finds that this has a bigger impact on the earnings of graduates and those without a degree but with A levels.

On entry to the labour market, men and women earn roughly the same. People’s wages tend to rise during their 20s, but men’s rise slightly faster than women’s, causing a pay gap to open and widen – but slowly at first. Average (mean) men’s wages continue to grow during their 30s and a bit during their 40s. However, average women’s wages flatline. Thus the wage gap grows substantially, especially for the higher educated.

The paper argues that the arrival of children is a major contributing factor to this picture. It looks at the gap before and after the arrival of children. “The crucial observation is that the gap opens up gradually after the first child arrives and continues to widen for many years after that point.” By 12 years after the first child is born, the wage gap has widened to 33%.

The paper does not offer reasons for the small gap that exists before the arrival of children. But it does give possible reasons for the widening gap after having children. A major one, it suggests, has to do with labour market experience.

“As women are likely to do less paid work after the arrival of children, the level of labour market experience they have falls further and further behind that of their male counterparts, and the wage gap therefore widens.” They may also miss out on promotions.

Each year a woman spends away from the labour market is associated with an average 2% drop in pay compared with those who remain in work. For those with at least A levels, the penalty is 4%; but there is no drop in pay for those without A levels.

Other possible explanations include mothers taking work that requires a lower skill level, and at lower hourly pay, in order to gain flexibility in working hours. However, the evidence suggests that women who move to part-time work on having a child suffer no immediate drop in pay. But their hourly pay does grow more slowly, thus contributing to a widening of the gap.

Another explanation is employers exercising market power to discriminate against women with children. The paper does not consider this explanation.

The articles discussing the paper look at policy implications and identify various things that can be done to narrow the gap. Read the paper and articles and try answering the questions below.

Is a competitive market the wrong model for analysing capitalism?

In the following article, Joseph Stiglitz argues that power rather than competition is a better starting point for analysing the working of capitalism. People’s rewards depend less on their marginal product than on their power over labour or capital (or lack of it).

As inequality has widened and concerns about it have grown, the competitive school, viewing individual returns in terms of marginal product, has become increasingly unable to explain how the economy works.

Thus the huge bonuses, often of millions of pounds per year, paid to many CEOs and other senior executives, are more a reflection of their power to set their bonuses, rather than of their contribution to their firms’ profitability. And these excessive rewards are not competed away.

Stiglitz examines how changes in technology and economic structure have led to the increase in power. Firms are more able to erect barriers to entry; network economies give advantages to incumbents; many firms, such as banks, are able to lobby governments to protect their market position; and many governments allow powerful vested interests to remain unchecked in the mistaken belief that market forces will provide the brakes on the accumulation and abuse of power. Monopoly profits persist and there is too little competition to erode them. Inequality deepens.

According to Stiglitz, the rationale for laissez-faire disappears if markets are based on entrenched power and exploitation.
