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

  1. How could we measure productivity?
  2. Why should we be optimistic about productivity if the real cost of labour is rising?
  3. 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?
  4. Why is a rise in productivity needed to improve living standards?

Labour markets can be a key indicator of the strength of an economy, with emphasis placed on measures including the unemployment rate and the rate of job creation. Over the past few decades, we have seen many changes in the UK labour market, with more women, more part-time jobs, flexible hours and a shift towards services. After the financial crisis, unemployment declined and more and more people were entering the labour market. But one criticism of this was zero-hours contracts. They are nothing new and were considered in earlier blogs.

Zero hours contracts are essentially what they say: a contract where you are guaranteed to work for zero hours. This means that under such a contract, there is no guarantee that you will have employment on any given day/week and hence this creates uncertainty. However, on the other side, there can be more flexibility with such a contract and with growth in female participation and part-time work, flexibility is essential for many people. James Sproule, Director of Policy at the Institute of Directors said:

“Zero hours contracts offer businesses and employees an important degree of flexibility. For skilled professionals, a degree of flexibility can boost their earning power, while flexibility also suits students and older people – the main users of zero-hours contracts – who cannot commit to a set number of hours each and every week.”

The ONS has found that businesses are using more zero-hours contracts, with a 6% rise. This reflects a growth in January from 1.4 million to 1.5 million zero-hours contracts, though this increase was not statistically significant. Over the past year, the use of these contracts has increased by 19%, from 624,000 people employed on them in 2014 to 744,000 people in 2015.

Although there has undoubtedly been an increase in the number of people employed on zero-hours contracts, there is also more recognition of these contracts. Therefore, part of the increase in the numbers could be down to this recognition and not just due to more and more people moving onto these contracts. With this greater flexibility, comes more opportunities for more people to enter the labour market. While this is a good thing, it can hide some other aspects. For example, if more people are working, it may suggest a fall in the rate of unemployment and a rise in employment, but perhaps this is misleading if some of those in employment are under-employed. The data revealed that:

On average, someone on a zero-hours contract usually works 25 hours a week, with around 40% of them wanting more hours, most from their current job, rather than in a different or additional one.

Furthermore, for some people there may be very few other options. However, there was also evidence that the possibility of zero-hours contracts has created opportunities for those who may otherwise not have entered the labour market: perhaps women re-entering the labour market and students in full time education. They also offer businesses greater flexibility and this may be a key way for the UK to improve efficiency and productivity. Jon Ingham from Glassdoor, an employment analyst said:

“It’s no great surprise to see the number of people on these contracts is on the up … It’s safe to say that employees who accept a zero hours contract do not do so as a career choice. For most it’s because they have limited options. For some it might be beneficial to have the flexibility to fit around their lifestyle but for others it’s a substandard contract which offers little in the way of benefits or security.”

The change in the structure of the labour market has been on-going and this may be a small change in amongst a much larger structural change. As the economy continues its recovery, we may see a return to the more typical working contract, but it appears that there will always be this greater demand for flexibility in working patterns and hence perhaps the zero-hours contracts do have a place in Britain.

Many Chinese people have taken to investing on the Chinese stock market, seeing it as a way of making a lot of money quickly. From October 2014 to June this year the market soared, rising by 126% from 2290 to 5166.

More and more people used their savings to buy stocks and China now has over 90 million individual investors. And it was not just savings that were invested. Increasingly people have been borrowing money to invest, seeing it as an easy way of making money. Unlike stock markets in developed countries, where the majority of shares are held by financial organisations, such as pension funds, holdings by individuals account for about 80% of stocks on the Chinese market.

But since mid-June, share prices have plummeted by 32% (see chart). People have thus seen a huge fall in the value of their savings, while many others have found their shareholdings worth less than their debts. The fall, like the rise that preceded it, has been driven by speculation, fuelled by first optimism and then pessimism.

The Chinese government is worried that the fall might dampen investment and economic growth. It has thus has been supplying liquidity to various institutions to buy shares, but this has had little effect and is dismissed by many as meddling. What is more it could expose companies which take advantage of the liquidity to greater risk.

So serious has been the rout, that over 50% of listed companies have halted trading on the mainland Chinese stock exchanges.

So just why has there been this bubble and why has it burst? What implications will it have for (a) China and (b) the rest of the world? The following articles explore the issues.

With worries about Greek exit from the eurozone, with the unlikelihood of further quantitative easing in the USA and the UK, with interest rates likely to rise in the medium term, and with Chinese growth predicted to be more moderate, many market analysts are forecasting that stock markets are likely to fall in the near future. Indeed, markets are already down over the past few weeks. Since late April/early May, the FTSE is down 4.5%; the German DAX index is down 7.0%; the French CAC40 index is down 6.9%; and the US Dow Jones index is down 2.3%. But does this give us an indication of what is likely to happen over the coming months?

If stock markets were perfectly efficient, then all possible information about the future will already have been taken into account and will all be reflected in current share prices. It would be impossible to ‘get ahead of the game’.

It is only if market participants have imperfect information and if you have better information than other people that you can are likely to predict correctly what will happen. Even then, the markets might be buffeted by random and hence unpredictable shocks.

Some people correctly predicted things in the past: such as crashes or booms. But in many cases, this was luck and their subsequent predictions have proved to be wrong. When financial advisers or newspaper columnists give advice, they are often wrong. If they were reliably right, then people would follow their advice and markets would rapidly adjust to their predictions.

If Greece were definitely to exit the euro, if interest rates were definitely to rise in the near future, if it became generally believed that stock markets were overvalued, then stock markets would probably fall. But these things may not happen. After all, people have been predicting a rise in interest rates from their ultra-low levels for many months – and it hasn’t happened yet, and may not happen for some time to come – but it may!

If you want to buy shares, you might just as well buy them at random – or randomly sell any you already have. As Tetlock says, quoted in the Nasdaq article:

“Even the most astute observers will fail to outperform random prediction generators – the functional equivalent of dart-throwing chimps.”

And yet, people do believe that they can predict what is going to happen to stock markets – if not precisely, then at least roughly. Are they deluded, or can looking calmly at likely political and economic events put them one step ahead of other people who perhaps behave more reactively and emotionally?

You may be used to these types of blogs by now … On my commute to work on the 18th May, I listened to Start the Week on BBC radio 4 and happened upon a fascinating discussion on inequality.

Of those discussing the issue, one certainly needs no introduction: Joseph Stiglitz, a prominent economist, author and commentator on economics, in particular on inequality. He was joined by Steve Hilton, who has worked for David Cameron for many years in providing advice on a range of issues, including inequality and strategy and has written on existing institutions and their effectiveness. The final panellist was Masha Gessen, who has written extensively on Russia and in particular on the journey of the infamous Boston Bomber.

Though the discussion covers a variety of areas relevant to economics, one key area that is addressed is inequality and the policies that are being used to address the causes and the symptoms. You can access the 45-minute discussion at the link below.
