In the blog post, Global warning, we looked at the use of unconventional macroeconomic policies to deal with the slow pace of economic growth around the world. One of the articles was by Nouriel Roubini. In the linked article below, he argues that slow economic growth may be the new global norm.
At the centre of the problem is a fall in the rate of potential economic growth. This has been caused by a lack of investment, which has slowed the pace of innovation and the growth in labour productivity.
The lack of investment, in turn, has been caused by a lack of spending by both households and governments. What is the point in investing in new capacity, argue firms, if they already have spare capacity?
Low consumer spending is partly the result of a redistribution of income from low- and middle-income households (who have a high marginal propensity to consume) to high-income households and corporations (who have a low mpc). Low spending is also the result of both consumers and governments attempting to reduce their levels of debt by cutting back spending.
Low growth leads to hysteresis – the process whereby low actual growth leads to low potential growth. The reason is that the unemployed become deskilled and the lack of investment by firms reduces the innovation that is necessary to embed new technologies.
Read Roubini’s analysis and consider the policy implications.

Has the global economic growth malaise become the ‘new normal’? The Guardian, Nouriel Roubini (2/5/16)
Questions
- Explain what is meant by ‘hysteresis’ and how the concept is relevant in explaining low global economic growth.
- Why has there been a reduction in the marginal propensity to consume in recent years? What is the implication of this for the multiplier and economic recovery?
- Explain what Roubini means by ‘a painful de-leveraging process’. What are the implications of this process?
- How important are structural reforms and what forms could these take? Why has there been a reluctance for governments to institute such reforms?
- ‘Asymmetric adjustment between debtor and creditor economies has also undermined growth.’ Explain what Roubini means by this.
- Why are governments reluctant to use fiscal policy to boost both actual and potential economic growth?
- What feasible policy measures could be taken to boost actual and potential economic growth?
Productivity has been a bit of a problem for the UK economy for a number of years. Earlier posts from 2015 have discussed the trend in Tackling the UK’s poor productivity and The UK’s poor productivity record. Although the so-called ‘productivity gap’ has been targeted by the government, with George Osborne promising to take steps to encourage more long-term investment in infrastructure and create better incentives for businesses to improve productivity, the latest data suggest that the problem remains.
The ONS has found that the UK continues to lag behind the other members of the G7, but perhaps more concerning is that the gap has grown to its biggest since 1991. The data showed that output per hour worked was 20 percentage points lower in the UK than the average for the other G7 countries. The economic downturn did cause falls in productivity, but the UK has not recovered as much as other advanced nations. One of the reasons, according to the Howard Archer, chief UK economist at IHS Global Insight is that it ‘had been held back since the financial crisis by the creation of lots of low-skilled, low-paid jobs’. These are the jobs where productivity is lowest and this may be causing the productivity gap to expand. Other cited reasons include the lack of investment which Osborne is attempting to address, fewer innovations and problems of finance.
Despite these rather dis-heartening data, there are some signs that things have begun to turn around. In the first quarter of 2015, output per hour worked did increase at the fastest annual growth rate in 3 years and Howard Archer confirmed that this did show ‘clear sign that UK productivity is now seeing much-needed improvement.’ There are other signs that we should be optimistic, delivered by the Bank of England. Sir John Cunliffe, Deputy Governor for financial stability said:
“firms have a greater incentive to find efficiency gains and to switch away from more labour-intensive forms of production. This should boost productivity.”
The reason given for this optimism is the increase in the real cost of labour relative to the cost of investment. So, a bit of a mixed picture here. UK productivity remains a cause for concern and given its importance in improving living standards, the Conservative government will be keen to demonstrate that its policies are closing the productivity gap. The latest data is more promising, but that still leaves a long way to go. The following articles consider this data and news.

Questions
- How could we measure productivity?
- Why should we be optimistic about productivity if the real cost of labour is rising?
- If jobs are being created at slower rate and the economy is still expanding, why does this suggest that productivity is rising? What does it suggest about pay?
- Why is a rise in productivity needed to improve living standards?
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.

Questions
- Define (a) labour productivity; (b) capital productivity; (c) total factor productivity.
- Why has the UK experienced lower productivity than other developed countries?
- Why may the UK’s lower unemployment than other countries in the post-recession period be the direct consequence of lower productivity growth?
- For what reasons might it be difficult for the government to achieve a significant increase in UK productivity?
- How might demand-side policy negatively impact on the supply-side policies that the government might adopt to increase productivity?
- How might the period up to and beyond the referendum in the UK on continuing EU membership impact on productivity?
- How might poor productivity be tackled?
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.

Questions
- How can productivity be measured? What are the advantages and disadvantages of using specific measures?
- Draw a diagram to show the effects on equilibrium national income of (a) a productivity increase, but offset by a fall in the number of hours worked; (b) a productivity increase with hours worked remaining the same; (c) a rise in hours worked with no increase in productivity. Assume that actual output depends on aggregate demand.
- Is poor productivity growth good for employment? Explain.
- Why is productivity in the UK lower now than in 2008?
- What policies can be pursued to increase productivity in the UK?
UK unemployment fell by 4000 to 2.51 million in second quarter of this year. But this was too small to have any significant effect on the unemployment rate, which remained at 7.8%.
According to the forward guidance issued by the Bank of England, Bank Rate will stay at 0.5%, barring serious unforeseen circumstances, until unemployment reaches 7%. So will this be soon?
There are good reasons to suggest that the answer is no. Reasons include the following:
(a) Many firms may choose to employ their part-time workers for more hours, rather than taking on extra staff, if the economy picks up.
(b) The recovery is being fuelled by a rise in consumption, which, in turn, is being financed by people drawing on savings or borrowing more. The household saving ratio fell from 7.4% in 2012 Q1 to 4.2% in 2013 Q1. This trend will be unsustainable over the long run, especially as the Bank of England may see a rapid rise in borrowing/decline in saving as serious enough to raise interest rates before the unemployment rate has fallen to 7%.
(c) Despite the modest recovery, people’s average real incomes are well below the levels prior to the deep recession of 2008/9.
