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.

Macronomics

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.

The engine of global productivity stuck in first gear

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.

The UK productivity puzzle

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.

The world economic outlook – as seen by the IMF

The IMF has just published its six-monthly World Economic Outlook. It expects world aggregate demand and growth to remain subdued. A combination of worries about the effects of Brexit and slower-than-expected growth in the USA has led the IMF to revise its forecasts for growth for both 2016 and 2017 downward by 0.1 percentage points compared with its April 2016 forecast. To quote the summary of the report:

Global growth is projected to slow to 3.1 percent in 2016 before recovering to 3.4 percent in 2017. The forecast, revised down by 0.1 percentage point for 2016 and 2017 relative to April, reflects a more subdued outlook for advanced economies following the June UK vote in favour of leaving the European Union (Brexit) and weaker-than-expected growth in the United States. These developments have put further downward pressure on global interest rates, as monetary policy is now expected to remain accommodative for longer.

Although the market reaction to the Brexit shock was reassuringly orderly, the ultimate impact remains very unclear, as the fate of institutional and trade arrangements between the United Kingdom and the European Union is uncertain.

The IMF is pessimistic about the outlook for advanced countries. It identifies political uncertainty and concerns about immigration and integration resulting in a rise in demands for populist, inward-looking policies as the major risk factors.

It is more optimistic about growth prospect for some emerging market economies, especially in Asia, but sees a sharp slowdown in other developing countries, especially in sub-Saharan Africa and in countries generally which rely on commodity exports during a period of lower commodity prices.

With little scope for further easing of monetary policy, the IMF recommends the increased use of fiscal policies:

Accommodative monetary policy alone cannot lift demand sufficiently, and fiscal support — calibrated to the amount of space available and oriented toward policies that protect the vulnerable and lift medium-term growth prospects — therefore remains essential for generating momentum and avoiding a lasting downshift in medium-term inflation expectations.

These fiscal policies should be accompanied by supply-side policies focused on structural reforms that can offset waning potential economic growth. These should include efforts to “boost labour force participation, improve the matching process in labour markets, and promote investment in research and development and innovation.”

Producing growth without production

In our recent blog constructing growth without production: The UK growth paradox we saw that the provisional estimate of economic growth in the UK in the final quarter of 2015 was 0.5 per cent. This was buoyed by service sector growth of 0.7 per cent. Meanwhile, construction sector output was estimated to have fallen by 0.1 per cent and production in the production industries by 0.2 per cent. The ONS Index of Production released on 11 February suggests the decline in production activity in the final quarter might have been has much as 0.5 per cent further pointing to unbalanced industrial growth.

The production industries today account for about 15 per cent of UK output which is small in comparison to the roughly 79 per cent from service-sector industries. Chart 1 shows the quarterly rate of growth in UK industrial production since the 1980s. (Click here for a PowerPoint of the chart). Over this period the average quarterly rate of growth in industrial output has been a mere 0.1 per cent compared with 0.5 per cent for total economic output and 0.7 per cent for the service sector. As a result, the importance of the production industries as a driver of economic output has declined.

Across 2015 industrial production rose by 1 per cent while the total output of the economy grew by 2.2 per cent. Industrial output comprises four main components. Of these, output from mining and quarrying grew in 2015 by 6.6 per cent, water, sewerage and waste management by 3.1 per cent, electricity, gas, steam and air conditioning by 0.3 per cent, while manufacturing output contracted by 0.2 per cent.

Chart 2 shows the path of industrial output since 2006. (Click here for a PowerPoint of the chart). In particular, it allows us to analyse the effect of the financial crisis and the global economic downturn. Whereas the total output of the economy surpassed its 2008 Q1 peak in 2013 Q2, driven by the service sector, total industrial output in 2015 Q4 remains 9.9 per cent below its 2008 Q1 level. Among its component parts, output in mining and quarrying is 31 per cent lower, electricity, gas, steam and air conditioning output is 12.2 per cent lower and manufacturing 6.5 per cent lower. Only the output of water, sewerage and waste management is greater – some 7.4 per cent higher.

The data point to the industrial composition of UK remaining heavily skewed towards the service sector and, hence, to service-sector industries driving economic growth. A key talking point is the extent to which this matters. On one hand we might point to the deindustrialisation captured by the data. This has had profound implications for certain regions of the United Kingdom and in particular for living standards in certain communities. Industrial change poses challenges for the UK labour force and for policymakers trying to affect the skills of workers needed in a changing economy. It has had a profound impact on the country’s balance of trade in goods: we consistently run a balance of trade deficit in goods. On the other hand we might argue that the UK does services well. We might be said to have a comparative advantage in this area. Whatever, your view point the latest industrial production data show the fragility of UK industrial output.

Constructing growth without construction: The UK growth paradox

In the blog the service sector continues to drive the UK business cycle written in October 2014 we observed how UK growth was being driven by the service sector while other industrial sectors struggled. The contrasting performance across UK industry appears now to be even more marked. The latest GDP numbers from the Office for National Statistics contained in Gross Domestic Product: Preliminary Estimate, Quarter 4 (Oct to Dec) 2015 show the economy’s output expanded by 0.5 per cent in the fourth quarter. Yet the construction sector is in recession following contractions of 1.9 per cent (Q3) and 0.1 per cent (Q4). Here we update our earlier blog to evidence the UK’s growth paradox.

Preliminary estimates suggest that the UK economy expanded by 0.5 per cent in the final quarter of 2015 following on from growth of of 0.4 per cent in the third quarter. 2015 as a whole saw output grow by 2.2 per cent, down from 2.9 per cent in 2014 and a little below the average over the past 60 years of around 2.6 per cent.

Chart 1 shows quarterly economic growth since 1980s (Click here for a PowerPoint of the chart). It illustrates nicely the inherent volatility of economies – one of the threshold concepts in economics.The average quarterly rate of growth since 1980 has been 0.5 per cent so on the face of it, a quarterly growth number of 0.5 per cent might seem to paint a picture of sustainable growth. Yet, the industrial make up of growth is far from balanced.

Consider now Chart 2 (Click here for a PowerPoint of the chart). It allows us to analyse more recent events by tracking how industrial output has evolved since 2006. It suggests an unbalanced recovery following the financial crisis. In 2015 Q4 the economy’s total output was 6.6 per cent higher than in 2008 Q1 with service-sector output 11.6 per cent higher. However, a very different picture emerges for the other principal industrial types.

The economy’s total output surpassed its 2008 Q1 peak in 2013 Q2, but output across the production industries in 2015 Q4 remains 9.4 per cent lower than in 2008 Q1 (and 6.4 per cent lower specifically within manufacturing) and 4.2 per cent lower in the construction sector. However, output in the agricultural sector has rebounded and is now 8.4 per cent higher than in 2008 Q1.

The growth data continue to show the British economy struggling to rebalance its industrial composition. With output in construction in 2015 Q4 2 per cent lower than it was in Q2 and manufacturing output 0.4 per cent lower, UK growth remains stubbornly dependent on the service sector.

What’s the outlook for the global economy?

The International Monetary Fund has just published its six-monthly World Economic Outlook (WEO). The publication assesses the state of the global economy and forecasts economic growth and other indicators over the next few years. So what is this latest edition predicting?

Well, once again the IMF had to adjust its global economic growth forecasts down from those made six months ago, which in turn were lower than those made a year ago. As Larry Elliott comments in the Guardian article linked below:

Every year, economists at the fund predict that recovery is about to move up a gear, and every year they are disappointed. The IMF has over-estimated global growth by one percentage point a year on average for the past four years.

In this latest edition, the IMF is predicting that growth in 2015 will be slightly higher in developed countries than in 2014 (2.0% compared with 1.8%), but will continue to slow for the fifth year in emerging market and developing countries (4.0% in 2015 compared with 4.6% in 2014 and 7.5% in 2010).

In an environment of declining commodity prices, reduced capital flows to emerging markets and pressure on their currencies, and increasing financial market volatility, downside risks to the outlook have risen, particularly for emerging market and developing economies.

So what is the cause of this sluggish growth in developed countries and lower growth in developing countries? Is lower long-term growth the new norm? Or is this a cyclical effect – albeit protracted – with the world economy set to resume its pre-financial-crisis growth rates eventually?

To achieve faster economic growth in the longer term, potential national output must grow more rapidly. This can be achieved by a combination of more rapid technological progress and higher investment in both physical and human capital. But in the short term, aggregate demand must expand sufficiently rapidly. Higher short-term growth will encourage higher investment, which in turn will encourage faster growth in potential national output.

But aggregate demand remains subdued. Many countries are battling to cut budget deficits, and lending to the private sector is being constrained by banks still seeking to repair their balance sheets. Slowing growth in China and other emerging economies is dampening demand for raw materials and this is impacting on primary exporting countries, which are faced with lower exports and lower commodity prices.

Quantitative easing and rock bottom interest rates have helped somewhat to offset these adverse effects on aggregate demand, but as the USA and UK come closer to raising interest rates, so this could dampen global demand further and cause capital to flow from developing countries to the USA in search of higher interest rates. This will put downward pressure on developing countries’ exchange rates, which, while making their exports more competitive, will make it harder for them to finance dollar-denominated debt.

As we have seen, long-term growth depends on growth in potential output, but productivity growth has been slower since the financial crisis. As the Foreword to the report states:

The ongoing experience of slow productivity growth suggests that long-run potential output growth may have fallen broadly across economies. Persistently low investment helps explain limited labour productivity and wage gains, although the joint productivity of all factors of production, not just labour, has also been slow. Low aggregate demand is one factor that discourages investment, as the last World Economic Outlook report showed. Slow expected potential growth itself dampens aggregate demand, further limiting investment, in a vicious circle.

But is this lower growth in potential output entirely the result of lower demand? And will the effect be permanent? Is it a form of hysteresis, with the effect persisting even when the initial causes have disappeared? Or will advances in technology, especially in the fields of robotics, nanotechnology and bioengineering, allow potential growth to resume once confidence returns?

Which brings us back to the short and medium terms. What can be done by governments to stimulate sustained recovery? The IMF proposes a focus on productive infrastructure investment, which will increase both aggregate demand and aggregate supply, and also structural reforms. At the same time, loose monetary policy should continue for some time – certainly as long as the current era of falling commodity prices, low inflation and sluggish growth in demand persists.

Questions

  1. Look at the forecasts made in the WEO October editions of 2007, 2010 and 2012 for economic growth two years ahead and compare them with the actual growth experienced. How do you explain the differences?
  2. Why is forecasting even two years ahead fraught with difficulties?
  3. What factors would cause a rise in (a) potential output; (b) potential growth?
  4. What is the relationship between actual and potential economic growth?
  5. Explain what is meant by hysteresis. Why may recessions have a permanent negative effect, not only on trend productivity levels, but on trend productivity growth?
  6. What are the current downside risks to the global economy?
  7. Why have commodity prices fallen? Who gains and who loses from lower commodity prices? Does it matter if falling commodity prices in commodity importing countries result in negative inflation?
  8. To what extent can exchange rate depreciation help commodity exporting countries?
  9. What is meant by the output gap? How have IMF estimates of the size of the output gap changed and what is the implication of this for actual and potential economic growth?

Tackling the UK’s poor productivity

As we saw in the blog post The UK’s poor productivity record, the UK’s productivity, as measured by output per hour worked, has grown much slower than in other major developed countries since the financial crisis. In fact, output per hour is lower now than in 2008. In France and Germany it is around 3 per higher than in 2008; in Japan it is nearly 6% higher; in the USA it is over 8% higher; and in Ireland it is 12% higher.

The chart below shows international comparisons of labour productivity from 2000 to 2014. (Click here for a PowerPoint of the chart.)

And it is not just labour productivity that has fallen in the UK. Total factor productivity of labour and capital combined has also fallen. This reflects the fall in business investment after the financial crisis and, more recently, meeting the demand for extra output by employing more labour rather than by investing in extra capital.

In his first major speech since the election, the Chancellor of the Exchequer, George Osborne, told the CBI that the government was intent on tackling the problem of low and stagnant productivity. This would require investment in infrastructure, such as high-speed rail, better roads, superfast broadband and a new runway in the south east. It would require investment in education, training and research; it would involve cutting red tape for business; it would require making it easier for both parents in a family to work by cutting the cost of childcare. The details of the government’s policies would be made clear in the soon-to-be published Productivity Plan.

But how much difference can the government make? Are there intractable problems that will prove virtually impossible to overcome? How much, indeed, can a government do, however much it would like to? The articles explore the issues.
