These are challenging times for business. Economic growth has weakened markedly over the past 18 months with output currently growing at an annual rate of around 1.5 per cent, a percentage point below the long-term average. Spending power continues to be squeezed, with the annual rate of inflation in October reported to be running at 3.1 per cent compared to annual earnings growth of 2.5 per cent (see the squeeze continues). Moreover, consumer confidence remains fragile with households continuing to express particular concerns about the general economy and unemployment.

Here, we update our blog of July 2016 which, following the UK vote to leave the European Union, noted the fears for UK growth as confidence fell sharply. Consumer confidence is frequently identified by macro-economists as an important source of economic volatility. Indeed many macro models use a change in consumer confidence as a means of illustrating how economic shocks affect a range of macro variables, including growth, employment and inflation. Many economists agree that, in the short term at least, falling levels of confidence adversely affect activity because aggregate demand falls as households spend less.

The European Commission’s confidence measure is collated from questions in a monthly survey. In the UK around 2000 individuals are surveyed. Across the EU as a whole over 41 000 people are surveyed. In the survey individuals are asked a series of 12 questions which are designed to provide information on spending and saving intentions. These questions include perceptions of financial well-being, the general economic situation, consumer prices, unemployment, saving and the undertaking of major purchases.

The responses elicit either negative or positive responses. For example, respondents may feel that over the next 12 months the financial situation of their household will improve a little or a lot, stay the same or deteriorate a little or a lot. A weighted balance of positive over negative replies can be calculated. The balance can vary from -100, when all respondents choose the most negative option, to +100, when all respondents choose the most positive option.

The European Commission’s principal consumer confidence indicator is the average of the balances of four of the twelve questions posed: the financial situation of households, the general economic situation, unemployment expectations (with inverted sign) and savings, all over the next 12 months. These forward-looking balances are seasonally adjusted. The aggregate confidence indicator is thought to track developments in households’ spending intentions and, in turn, likely movements in the rate of growth of household consumption.

Chart 1 shows the consumer confidence indicator for the UK. The long-term average of –8.6 shows that negative responses across the four questions typically outweigh positive responses. In November 2017 the confidence balance stood at -5.2 roughly on par with its value in the previous two months, though marginally up on values of close to -7 over the summer. However, as recently as the beginning of 2016 the aggregate confidence score was running at around +4. In this context, current levels do constitute a significant change in consumer sentiment, changes which do ordinarily mark similar turning points in economic activity.(Click here to download a PowerPoint of the chart.)

Chart 2 allows to look behind the European Commission’s headline confidence indicator for the UK by looking at its four component balances. From it, we can see a deterioration in all four components. However, by far the most significant change in the individual confidence balances has been the sharp deterioration in expectations for the general economy. In November the forward-looking general economic situation stood at -25.5, compared to its long-run average of -11.6. (Click here to download a PowerPoint of the chart.)

The fall in UK consumer confidence is even more stark when compared to developments in consumer confidence across the whole of the European Union and in the 19 countries that make up the Euro area. Chart 3 shows how UK consumer confidence recovered relatively more strongly following the financial crisis of the late 2000s. The headline confidence indicator rose strongly from the middle of 2013 and was consistently in positive territory during 2014, 2015 and into 2016. The fall in consumer confidence in the UK has seen the headline confidence measure fall below that for the EU and the euro area. (Click here to download a PowerPoint of the chart.)

Consumer (and business) confidence is closely linked to uncertainty. The circumstances following the UK vote to leave the EU have undoubtedly created the conditions for acute uncertainty. Uncertainty breeds caution. Economists sometimes talk about spending being affected by two conflicting motives: prudence and impatience. While impatience creates a desire for spending now, prudence pushes us towards saving and insuring ourselves against uncertainty and unforeseen events. The worry is that the twin forces of fragile confidence and squeezed real earning are weighting heavily in favour of prudence and patience (a reduction in impatience). Going forward, this could create the conditions for a sustained period of subdued growth which, if it were to impact heavily on firms’ investment plans, could adversely impact on the economy’s productive potential. The hope is that the Brexit negotiations can move apace to reduce uncertainty and limit uncertainty’s adverse impact on economic activity.

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.

The French have elected Emmanuel Macron as their new President. He claims to be from the economic centre. But just what does this imply for his vision of how the French economy should be run? What policies is he likely to put in place? Can these policies rightly be described as ‘centrist’? In practice, some of his policies are advocated by the centre right and some by the centre left.

He wants to institute policies that are pro business and will have the effect of stimulating private investment, increasing productivity and resulting in faster economic growth.

His pro-business policies include: reducing corporation tax from its current 33.3% to 25%, the hope being that firms will invest the money that this will free up; reducing labour taxes on companies for employing low-wage workers; making the current 35-hour working week less rigid by giving firms greater ability to negotiate special arrangements with trade unions.

Other policies drawn from the centre right include reducing the size of the state. Currently, general government spending in France, at 56.5% of GDP, is the highest of the G7 countries. Italy’s is the next highest at 49.6%, followed by Germany at 44.3%, Canada at 40.8%, the UK at 39.4%, Japan at 36.8% and the USA at 35.2%. President Macron wants to reduce the figure for France to 52% over his five-year term. This will be achieved by cutting 120,000 public-sector jobs and reducing state spending by €60bn. He plans, thereby, to reduce the general government deficit from its 2016 level of 3.4% of GDP to 1% by 2022 and reduce the general government debt from 96.0% of GDP to 93.2% over the same period.

Drawing from centre-left policies he plans to increase public investment by €50bn, including €15bn on training, €15bn on green energy and €5bn each on transport, health, agriculture and the modernisation of public administration. But as this additional expenditure is less than the planned savings through greater efficiency and as GDP is projected to grow, this is still consistent with achieving a reduction in the general government deficit as a percentage of GDP. He has also pledged to extend welfare spending. This will include making the self-employed eligibile for unemployment benefits.

M Macron isalso strongly supportive of France’s membership of the EU and the euro. Nevertheless he wants the EU to be reformed to make it more efficient and achieve significant cost savings.

According to Christine Lagarde, Managing Director of the IMF, the slow growth in global productivity is acting as a brake on the growth in potential income and is thus holding back the growth in living standards. In a recent speech in Washington she said that:

Over the past decade, there have been sharp slowdowns in measured output per worker and total factor productivity – which can be seen as a measure of innovation. In advanced economies, for example, productivity growth has dropped to 0.3 per cent, down from a pre-crisis average of about 1 per cent. This trend has also affected many emerging and developing countries, including China.

We estimate that, if total factor productivity growth had followed its pre-crisis trend, overall GDP in advanced economies would be about 5 percent higher today. That would be the equivalent of adding another Japan – and more – to the global economy.

So why has productivity growth slowed to well below pre-crisis rates? One reason is an ageing working population, with older workers acquiring new skills less quickly. A second is the slowdown in world trade and, with it, the competitive pressure for firms to invest in the latest technologies.

A third is the continuing effect of the financial crisis, with many highly indebted firms forced to make deep cuts in investment and many others being cautious about innovating. The crisis has dampened risk taking – a key component of innovation.

What is clear, said Lagarde, is that more innovation is needed to restore productivity growth. But markets alone cannot achieve this, as the benefits of invention and innovation are, to some extent, public goods. They have considerable positive externalities.

She thus called on governments to give high priority to stimulating productivity growth and unleashing entrepreneurial energy. There are several things governments can do. These include market-orientated supply-side policies, such as removing unnecessary barriers to competition, driving forward international free trade and cutting red tape. They also include direct intervention through greater investment in education and training, infrastructure and public-sector R&D. They also include giving subsidies and/or tax relief for private-sector R&D.

Banks too have a role in chanelling finance away from low-productivity firms and towards ‘young and vibrant companies’.

It is important to recognise, she concluded, that innovation and structural change can lead to some people losing out, with job losses, low wages and social deprivation. Support should be given to such people through better education, retraining and employment incentives.

Both the financial and goods markets are heavily influenced by sentiment. And such sentiment tends to be self-reinforcing. If consumers and investors are pessimistic, they will not spend and not invest. The economy declines and this further worsens sentiment and further discourages consumption and investment. Banks become less willing to lend and stock markets fall. The falling stock markets discourage people from buying shares and so share prices fall further. The despondency becomes irrational and greatly exaggerates economic fundamentals.

This same irrationality applies in a boom. Here it becomes irrational exuberance. A boom encourages confidence and stimulates consumer spending and investment. This further stimulates the boom via the multiplier and accelerator and further inspires confidence. Banks are more willing to lend, which further feeds the expansion. Stock markets soar and destabilising speculation further pushes up share prices. There is a stock market bubble.

But bubbles burst. The question is whether the current global stock market boom, with share prices reaching record levels, represents a bubble. One indicator is the price/earnings (PE) ratio of shares. This is the ratio of share prices to earnings per share. Currently the ratio for the US index, S&P 500, is just over 26. This compares with a mean over the past 147 years of 15.64. The current ratio is the third highest after the peaks of the early 2000s and 2008/9.

An alternative measure of the PE ratio is the Shiller PE ratio (see also). This is named after Robert Shiller, who wrote the book Irrational Exuberance. Unlike conventional PE ratios, which only look at average earnings over the past four quarters, the Shiller PE ratio uses average earnings over the past 10 years. “Because this factors in earnings from the previous ten years, it is less prone to wild swings in any one year.”

The current level of the Shiller PE ratio is 29.14, the third highest on record, this time after the period running up to the Wall Street crash of 1929 and the dot-com bubble of the late 1990s. The mean Shiller PE ratio over the past 147 years is 16.72.

So are we in a period of irrational exuberance? And are stock markets experiencing a bubble that sooner or later will burst? The following articles explore these questions.
