Category: Economics 9e: Ch 09

Each January, world political and business leaders gather at the ski resort of Davos in Switzerland for the World Economic Forum. They discuss a range of economic and political issues with the hope of guiding policy.

This year, leaders meet at a time when the global political context has and is changing rapidly. This year the focus is on ‘Creating a Shared Future in a Fractured World’. As the Forum’s website states:

The global context has changed dramatically: geostrategic fissures have re-emerged on multiple fronts with wide-ranging political, economic and social consequences. Realpolitik is no longer just a relic of the Cold War. Economic prosperity and social cohesion are not one and the same. The global commons cannot protect or heal itself.

One of the main ‘fissures’ which threatens social cohesion is the widening gap between the very rich and the rest of the world. Indeed, inequality and poverty is one of the main agenda items at the Davos meeting and the Forum website includes an article titled, ‘We have built an unequal world. Here’s how we can change it’ (see second link in the Articles below). The article shows how the top 1% captured 27% of GDP growth between 1980 and 2016.

The first Guardian article below identifies seven different policy options to tackle the problem of inequality of income and wealth and asks you to say, using a drop-down menu, which one you think is most important. Perhaps it’s something you would like to do.

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.

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.

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.
