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.

Questions

  1. In measuring productivity, the ONS uses three indicators: output per worker, output per hour and output per job. Compare the relative usefulness of these three measures of productivity.
  2. How would you explain the marked difference in productivity between regions and cities within the UK?
  3. How do flexible labour markets impact on productivity?
  4. Why is investment as a percentage of GDP so low in the UK compared to that in most other developed countries (see)?
  5. Give some examples of industrial policy measures that could be adopted to increase productivity growth.
  6. Examine the extent to which very low interest rates and quantitative easing encourage productivity-enhancing investment.

Many politicians throughout the world,
not just on the centre and left, are arguing for increased spending on infrastructure. This was one of the key proposals of Donald Trump during his election campaign. In his election manifesto he pledged to “Transform America’s crumbling infrastructure into a golden opportunity for accelerated economic growth and more rapid productivity gains”.

Increased spending on inffrastructure has both demand- and supply-side effects.

Unless matched by cuts elsewhere, such spending will increase aggregate demand and could have a high multiplier effect if most of the inputs are domestic. Also there could be accelerator effects as the projects may stimulate private investment.

On the supply side, well-targeted infrastructure spending can directly increase productivity and cut costs of logistics and communications.

The combination of the demand- and supply-side effects could increase both potential and actual output and reduce unemployment.

So, if infrastructure projects can have such beneficial effects, why are politicians often so reluctant to give them the go-ahead?

Part of the problem is one of timing. The costs occur in the short run. These include demolition, construction and disruption. The direct benefits occur in the longer term, once the project is complete. And for complex projects this may be many years hence. It is true that demand-side benefits start to occur once construction has begun, but these benefits are widely dispersed and not easy to identify directly with the project.

Then there is the problem of externalities. The external costs of projects may include environmental costs and costs to local residents. This can lead to protests, public hearings and the need for detailed cost–benefit analysis. This can delay or even prevent projects from occurring.

The external benefits are to non-users of the project, such as a new bridge or bypass reducing congestion for users of existing routes. These make the private construction of many projects unprofitable, except with public subsidies or with public–private partnerships. So there does need to be a macroeconomic policy that favours publicly-funded infrastructure projects.

One type of investment that is less disruptive and can have shorter-term benefits is maintenance investment. Maintenance expenditure can avoid much more costly rebuilding expenditure later on. But this is often the first type of expenditure to be cut when public-sector budgets as squeezed, whether at the local or national level.

The problem of lack of infrastructure investment is very much a political problem. The politicians who give the go-ahead to such projects, such as high-speed rail, come in for criticisms from those bearing the short-run costs but they are gone from office once the benefits start to occur. They get the criticism but not the praise.

Economic forecasting came in for much criticism at the time of the financial crisis and credit crunch. Few economists had predicted the crisis and its consequences. Even Queen Elizabeth II, on a visit to the London School of Economics in November 2008, asked why economists had got it so wrong. Similar criticisms have emerged since the Brexit vote, with economic forecasters being accused of being excessively pessimistic about the outcome.

The accuracy of economic forecasts was one of the topics discussed by Andy Haldane, Chief Economist at the Bank of England. Speaking at the Institute for Government in London, he compared economic forecasting to weather forecasting (see section from 15’20” in the webcast):

“Remember that? Michael Fish getting up: ‘There’s no hurricane coming but it will be very windy in Spain.’ Very similar to the sort of reports central banks – naming no names – issued pre-crisis, ‘There is no hurricane coming but it might be very windy in the sub-prime sector.” (18’40”)

The problem with the standard economic models which were used for forecasting is that they were essentially equilibrium models which work reasonably well in ‘normal’ times. But when there is a large shock to the economic system, they work much less well. First, the shocks themselves are hard to predict. For example, the sub-prime crisis in 2007/8 was not foreseen by most economists.

Then there is the effect of the shocks. Large shocks are much harder to model as they can trigger strong reactions by consumers and firms, and governments too. These reactions are often hugely affected by sentiment. Bouts of pessimism or even panic can grip markets, as happened in late 2008 with the collapse of Lehman Brothers. Markets can tumble way beyond what would be expected by a calm adjustment to a shock.

It can work the other way too. Economists generally predicted that the Brexit vote would lead to a fall in GDP. However, despite a large depreciation of sterling, consumer sentiment held up better than was expected and the economy kept growing.

But is it fair to compare economic forecasting with weather forecasting? Weather forecasting is concerned with natural phenomena and only seeks to forecast with any accuracy a few days ahead. Economic forecasting, if used correctly, highlights the drivers of economic change, such as government policy or the Brexit vote, and their likely consequences, other things being equal. Given that economies are constantly being affected by economic shocks, including government or central bank actions, it is impossible to forecast the state of the macroeconomy with any accuracy.

This does not mean that forecasting is useless, as it can highlight the likely effects of policies and take into account the latest surveys of, say, consumer and business confidence. It can also give the most likely central forecast of the economy and the likely probabilities of variance from this central forecast. This is why many forecasts use ‘fan charts’: see, for example, Bank of England forecasts.

What economic forecasts cannot do is to predict the precise state of the economy in the future. However, they can be refined to take into account more realistic modelling, including the modelling of human behaviour, and more accurate data, including survey data. But, however refined they become, they can only ever give likely values for various economic variables or likely effects of policy measures.

The economic climate remains uncertain and, as we enter 2017, we look towards a new President in the USA, challenging negotiations in the EU and continuing troubles for High Street stores. One such example is Next, a High Street retailer that has recently seen a significant fall in share price.

Prices of clothing and footwear increased in December for the first time in two years, according to the British Retail Consortium, and Next is just one company that will suffer from these pressures. This retail chain is well established, with over 500 stores in the UK and Eire. It has embraced the internet, launching its online shopping in 1999 and it trades with customers in over 70 countries. However, despite all of the positive actions, Next has seen its share price fall by nearly 12% and is forecasting profits in 2017 to be hit, with a lack of growth in earnings reducing consumer spending and thus hitting sales.

The sales trends for Next are reminiscent of many other stores, with in-store sales falling and online sales rising. In the days leading up to Christmas, in-store sales fell by 3.5%, while online sales increased by over 5%. However, this is not the only trend that this latest data suggests. It also indicates that consumer spending on clothing and footwear is falling, with consumers instead spending more money on technology and other forms of entertainment. Kirsty McGregor from Drapers magazine said:

“I think what we’re seeing there is an underlying move away from spending so much money on clothing and footwear. People seem to be spending more money on going out and on technology, things like that.”

Furthermore, with price inflation expected to rise in 2017, and possibly above wage inflation, spending power is likely to be hit and it is spending on those more luxury items that will be cut. With Next’s share price falling, the retail sector overall was also hit, with other companies seeing their share prices fall as well, although some, such as B&M, bucked the trend. However, the problems facing Next are similar to those facing other stores.

But for Next there is more bad news. It appears that the retail chain has simply been underperforming for some time. We have seen other stores facing similar issues, such as BHS and Marks & Spencer. Neil Wilson from ETX Capital said:

“The simple problem is that Next is underperforming the market … UK retail sales have held up in the months following the Brexit vote but Next has suffered. It’s been suffering for a while and needs a turnaround plan … The brand is struggling for relevancy, and risks going the way of Marks & Spencer on the clothing front, appealing to an ever-narrower customer base.”

Brand identity and targeting customers are becoming ever more important in a highly competitive High Street that is facing growing competition from online traders. Next is not the first company to suffer from this and will certainly not be the last as we enter what many see as one of the most economically uncertain years since the financial crisis.

We have frequently looked at patterns in lending by financial institutions in our blogs given that many economies, like the UK, display cycles in credit. Central banks now pay considerable attention to the possibility of such cycles destabilising economies and causing financial distress to people and businesses. There is also increased interest here in the UK in bank lending data in light of Brexit. Patterns in credit flows may indicate whether it is affecting the lending choices of financial institutions and borrowing choices of people and businesses.

Data from the Bank of England’s Money and Credit – September 2016 statistical release shows net lending (lending net of repayments) by monetary financial institutions (MFIs) to individuals in September 2016 was £4.65 billion. This compares with £8.89 billion back in March 2016 which then was the highest monthly total since August 2007. However, the March figure was something of a spike in lending and this September’s figure is actually very slightly above the monthly average over the last 12 months, excluding March, of £4.5 billion. In other words, as yet, there is no discernible change in the pattern of credit flows post-Brexit.

Leaving aside the question of the economic impact of Brexit, we still need to consider what the credit data mean for financial stability and for our financial well-being. Chart 1 shows the annual flows of lending by banks and building societies since the mid 1990s. The chart evidences the cycles in secured lending and in consumer credit (unsecured lending) with its consequent implications for economic and financial-welling being.(Click here to download a PowerPoint of Chart 1.)

After the financial crisis, as Chart 1 shows, net lending to individuals collapsed. More recently, net lending has been on the rise both through secured lending and in consumer credit. The latest data show that annual flows have begun to plateau. Nonetheless, the total flow of credit in the 12 months to September of £58 billion compares with £33 billion and £41 billion in the 12 months to September 2014 and 2015 respectively. Having said this, in the 12 months to September 2007 the figure was £112 billion! £58 billion is currently equivalent to around about 3 per cent of GDP.

To more readily see the effect of the credit flows on debts stocks, Chart 2 shows the annual growth rate of net lending by MFIs. In essence, this mirrors the growth rate in the stocks of debt which is an important metric of financial well-being. The chart nicely captures the pick up in the growth of lending from around the start of 2013. What is particularly noticeable is the very strong rates of growth in net unsecured lending from MFIs. The growth of unsecured lending remains above 10 per cent, comparable with rates in the mid 2000s. (Click here to download a PowerPoint of Chart 2.)

The growth in debt stocks arising from lending continues to demonstrate the need for individuals to be mindful of their financial well-being. This caution is perhaps more important given the current economics uncertainties. The role of the Financial Policy Committee in the UK is to monitor the financial well-being of economic agents in the context of ensuring the resilience of the financial system. It therefore analyses the data on credit flows and debt stocks referred to in this blog along with other relevant metrics. At this moment its stance is not to apply any additional buffer – known as the Countercyclical Capital Buffer – on a financial institution’s exposures in the UK over and above internationally agreed standards. Regardless, the fact that it explicitly monitors financial well-being and risk shows just how significant the relationship between the financial system and economic outcomes is now regarded.
