Since the financial crisis of 2008–9, the UK has experienced the lowest growth in productivity for the past 250 years. This is the conclusion of a recent paper published in the National Institute Economics Review. Titled, Is the UK Productivity Slowdown Unprecedented, the authors, Nicholas Crafts of the University of Sussex and Terence C Mills of Loughborough University, argue that ‘the current productivity slowdown has resulted in productivity being 19.7 per cent below the pre-2008 trend path in 2018. This is nearly double the previous worst productivity shortfall ten years after the start of a downturn.’

According to ONS figures, productivity (output per hour worked) peaked in 2007 Q4. It did not regain this level until 2011 Q1 and by 2019 Q3 was still only 2.4% above the 2007 Q4 level. This represents an average annual growth rate over the period of just 0.28%. By contrast, the average annual growth rate of productivity for the 35 years prior to 2007 was 2.30%.

The chart illustrates this and shows the productivity gap, which is the amount by which output per hour is below trend output per hour from 1971 to 2007. By 2019 Q3 this gap was 27.5%. (Click here for a PowerPoint of the chart.) Clearly, this lack of growth in productivity over the past 12 years has severe implications for living standards. Labour productivity is a key determinant of potential GDP, which, in turn, is the major limiter of actual GDP.

Crafts and Mills explore the reasons for this dramatic slowdown in productivity. They identify three primary reasons.

The first is a slowdown in the impact of developments in ICT on productivity. The office and production revolutions that developments in computing and its uses had brought about have now become universal. New developments in ICT are now largely in terms of greater speed of computing and greater sophistication of software. Perhaps with an acceleration in the development of artificial intelligence and robotics, productivity growth may well increase in the relatively near future (see third article below).

The second cause is the prolonged impact of the banking crisis, with banks more cautious about lending and firms more cautious about borrowing for investment. What is more, the decline in investment directly impacts on potential output, and layoffs or restructuring can leave people with redundant skills. There is a hysteresis effect.

The third cause identified by Crafts and Mills is Brexit. Brexit and the uncertainty surrounding it has resulted in a decline in investment and ‘a diversion of top-management time towards Brexit planning and a relative shrinking of highly-productive exporters compared with less productive domestically orientated firms’.

The Brexit vote has caused shockwaves throughout European economies. But there is a potentially larger economic and political problem facing the EU and the eurozone more specifically. And that is the state of the Italian banking system and the Italian economy.

Italy is the third largest economy in the eurozone after Germany and France. Any serious economic weaknesses could have profound consequences for the rest of the eurozone and beyond.

At 135% of GDP, Italy’s public-sector debt is one the highest in the world; its banks are undercapitalised with a high proportion of bad debt; and it is still struggling to recover from the crisis of 2008–9. The Economist article elaborates:

The adult employment rate is lower than in any EU country bar Greece. The economy has been moribund for years, suffocated by over-regulation and feeble productivity. Amid stagnation and deflation, Italy’s banks are in deep trouble, burdened by some €360 billion of souring loans, the equivalent of a fifth of the country’s GDP. Collectively they have provisioned for only 45% of that amount. At best, Italy’s weak banks will throttle the country’s growth; at worst, some will go bust.

Since 2007, the economy has shrunk by 10%. And potential output has fallen too, as firms have closed. Unemployment is over 11%, with youth unemployment around 40%.

Things seem to be coming to a head. As confidence in the Italian banking system plummets, the Italian government would like to bail out the banks to try to restore confidence and encourage deposits and lending. But under new eurozone rules designed to protect taxpayers, it requires that the first line of support should be from bondholders. Such support is known as a ‘bail-in’.

If bondholders were large institutional investors, this might not be such a problem, but a significant proportion of bank bonds in Italy are held by small investors, encouraged to do so by tax relief. Bailing in the banks by requiring bondholders to bear significant losses in the value of their bonds could undermine the savings of many Italians and cause them severe hardship, especially those who had saved for their retirement.

So what is the solution? Italian banks need recapitalising to restore confidence and prevent a more serious crisis. However, there is limited scope for bailing in, unless small investors can be protected. And eurozone rules provide little scope for government funding for the banks. These rules should be relaxed under extreme circumstances. At the same time, policy needs to focus on making Italian banking more efficient.

Meanwhile, the IMF is forecasting that Italian economic growth will be less than 1% this year and little better in 2017. Part of the problem, claims the IMF, is the Brexit vote. This has heightened financial market volatility and increasead the risks for Italy with its fragile banking system. But the problems of the Italian economy run deeper and will require various supply-side policies to tackle low productivity, corruption, public-sector inefficiency and a financial system not fit for purpose. What the mix of these policies should be – whether market based or interventionist – is not just a question of effectiveness, but of political viability and democratic support.

Real GDP depends on two things: output per hour worked and the number of hours worked. On the surface, the UK economy is currently doing relatively well, with growth in 2014 of 2.8%. After several years of poor economic growth following the financial crisis of 2007/8, growth of 2.8% represents a return to the long-run average for the 20 years prior to the crisis.

But growth since 2010 has been entirely due to an increase in hours worked. On the one hand, this is good, as it has meant an increase in employment. In this respect, the UK is doing better than other major economies. But productivity has not grown and on this front, the UK is doing worse than other countries.

The first chart shows UK output per hour worked (click here for a PowerPoint). It is based on figures released by the ONS on 1 April 2015. Average annual growth in output per hour worked was 2.3% from 2000 to 2008. Since then, productivity growth has stalled and output per hour is now lower than at the peak in 2008.

The green line projects from 2008 what output per hour would have been if its growth had remained at 2.3%. It shows that by the end of 2014 output per hour would have been nearly 18% higher if productivity growth had been maintained.

The second chart compares UK productivity growth with other countries (click here for a PowerPoint). Up to 2008, UK productivity was rising slightly faster than in the other five countries illustrated. Since then, it has performed worse than the other five countries, especially since 2011.

Productivity growth increases potential GDP. It also increases actual GDP if the productivity increase is not offset by a fall in hours worked. A rise in hours worked without a rise in productivity, however, even though it results in an increase in actual output, does not increase potential output. If real GDP growth is to be sustained over the long term, there must be an increase in productivity and not just in hours worked.

The articles below examines this poor productivity performance and looks at reasons why it has been so bad.
