The Consumer Prices index (CPI) measures the rate of inflation and in October, this rate fell to 2.2%, bringing inflation to its lowest level since September 2012. For many, this drop in inflation came as a surprise, but it brings the rate much closer to the Bank of England’s target and thus reduces the pressure on changing interest rates.

The CPI is calculated by calculating the weighted average price of a basket of goods and comparing how this price level changes from one month to the next. Between September and October prices across a range of markets fell, thus bringing inflation to its lowest level in many months. Transport prices fell by their largest amount since mid-2009, in part driven by fuel price cuts at the big supermarkets and this was also accompanied by falls in education costs and food. The Mail Online article linked below gives a breakdown of the sectors where the largest price falls have taken place. One thing that has not yet been included in the data is the impact of the price rises by the energy companies. The impact of his will obviously be to raise energy costs and hence we can expect to see an impact on the CPI in the coming months, once the price rises take effect.

With inflation coming back on target, pressures on the Bank of England to raise interest rates have been reduced. When inflation was above the target rate, there were concerns that the Bank of England would need to raise interest rates to cut aggregate demand and thus bring inflation down.

However, the adverse effect of this would be a potential decline in growth. With inflation falling to 2.2%, this pressure has been removed and hence interest rates can continue to remain at the record low, with the objective of stimulating the economy. Chris Williamson from Markit said:

The easing in the rate of inflation and underlying price pressures will provide greater scope for monetary policy to be kept looser for longer and thereby helping ensure a sustainable upturn in the economy … Lower inflation reduces the risk of the Bank of England having to hike rates earlier than it may otherwise prefer to, allowing policy to focus on stimulating growth rather than warding off rising inflationary pressures.

The lower rate of inflation also has good news for consumers and businesses. Wages remain flat and thus the reduction in the CPI is crucial for consumers, as it improves their purchasing power. As for businesses, a low inflation environment creates more certainty, as inflation tends to be more stable. Businesses are more able to invest with confidence, again benefiting the economy. Any further falls in the CPI would bring inflation back to its target level of 2% and then undoubtedly concerns will turn back to the spectre of deflation, though with the recent announcements in energy price rises, perhaps we’re getting a little ahead of ourselves! Though we only need to look to countries such as Spain and Sweden where prices are falling to realise that it is certainly a possibility. The following articles consider the data and the impact.

Questions

  1. How is the CPI calculated?
  2. Use an AD/AS diagram to illustrate how prices have been brought back down. Is the reduction in inflation due to demand-side or supply-side factors?
  3. What are the benefits of low inflation?
  4. The Telegraph article mentions the possibility of deflation. What is deflation and why does it cause such concern?
  5. Explain why a fall in the rate of inflation eases pressure on the Bank of England.
  6. How does the rate of inflation affect the cost of living?
  7. Is a target rate of inflation a good idea?

First the good news. Employment is rising and unemployment is falling. Both claimant count rates and Labour Force Survey rates are down. Compared with a year ago, employment is up 279,092 to 29,869,489; LFS unemployment is down from 7.87% to 7.69%; and the claimant count rate is down from 4.7% to 4.0%.

Now the bad news. Even though more people are in employment, real wages have fallen. In other words, nominal wages have risen less fast than prices. Since 2009, real wages have fallen by 7.6% and have continued to fall throughout this period. The first chart illustrates this. It shows average weekly wage rates in 2005 prices. (Click here for a PowerPoint of the chart.)

The fall in real wages is an average for the whole country. Many people, especially those on low incomes, have seen their real wages fall much faster than the average. For many there is a real ‘cost of living’ crisis.

But why have real wages fallen despite the rise in employment? The answer is that output per hour worked has declined. This is illustrated in the second chart, which compares UK output per worker with that of other G7 countries. UK productivity has fallen both absolutely and relative to other G7 countries, most of which have had higher rates of investment.

The falling productivity in the UK requires more people to be employed to produce the same level of output. Part of what seems to be happening is that many employers have been prepared to keep workers on in return for lower real wages, even if demand from their customers is falling. And many workers have been prepared to accept real wage cuts in return for keeping their jobs.

Another part of the explanation is that the jobs that have been created have been largely in low-skilled, low-wage sectors of the economy, such as retailing and other parts of the service sector.

But falling productivity is only part of the reason for falling real wages. The other part is rising prices. A number of factors have contributed to this. These include a depreciation of the exchange rate back in 2008, the effects of which took some time to filter through into higher prices in the shops; a large rise in various commodity prices; and a rise in VAT and various other administered prices.

So what is the answer to falling real wages? The articles below consider the problem and some of the possible policy alternatives.

Questions

  1. How are real wages measured?
  2. Why have real wage rates fallen in the UK since 2009?
  3. What factors should be included when measuring living standards?
  4. Why has employment risen and unemployment fallen over the past two years?
  5. What factors could lead to a rise in real wages in the future?
  6. What government policies could be adopted to raise real wages?
  7. Assess these policies in terms of their likely short-term success and long-term sustainability.

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.

Questions

  1. What factors determine the rate of unemployment?
  2. With reference to the ONS data in Labour Market Statistics, August 2013 above, what has happened to (a) the long-term unemployment rate; (b) the unemployment rate for 18–24 year olds?
  3. How would you define ‘living standards’?
  4. How is labour productivity relevant to the question of whether unemployment is likely to fall?
  5. How much have living standards fallen since 2008?
  6. Under what circumstances might the Bank of England raise interest rates before the rate of unemployment has fallen to 7%?
  7. Property prices are beginning to rise. Consider the effects of this and whether, on balance, a rise in property prices is beneficial.

Tight fiscal policies are being pursued in many countries to deal with high public-sector deficits that resulted from the deep recession of 2008/9. This has put the main onus on monetary policy as the means of stimulating recovery. As a result we have seen record low interest rates around the world, set at only slightly above zero in the main industrialised countries for the past 4½ years. In addition, there have been large increases in narrow money as a result of massive programmes of quantitative easing.

Yet recovery remains fragile in many countries, including the UK and much of the rest of Europe. And a new problem has been worries by potential investors that loose monetary policy may be soon coming to an end. As the June blog The difficult exit from cheap money pointed out:

The US economy has been showing stronger growth in recent months and, as a result, the Fed has indicated that it may soon have to begin tightening monetary policy. It is not doing so yet, nor are other central banks, but the concern that this may happen in the medium term has been enough to persuade many investors that stock markets are likely to fall as money eventually becomes tighter. Given the high degree of speculation on stock markets, this has led to a large-scale selling of shares as investors try to ‘get ahead of the curve’.

Central banks have responded with a new approach to monetary policy. This is known as ‘forward guidance’. The idea is to manage expectations by saying what the central bank will do over the coming months.

The USA was the first to pursue this approach. In September 2012 the Fed committed to bond purchase of $40bn per month (increased to $85bn per month in January 2013) for the foreseeable future; and record low interest rates of between 0% and 0.25% would continue. Indeed, as pointed out above, it was the ‘guidance’ last month that such a policy would be tapered off at some point, that sent stock markets falling in June.

The Fed has since revised its guidance. On 10 July, Ben Bernanke, the Fed Chairman said that monetary policy would not be tightened for the foreseeable future. With fiscal policy having been tightened, QE would continue and interest rates would not be raised until unemployment had fallen to 6.5%.

Japan has been issuing forward guidance since last December. Its declared aim has been to lower the exchange rate and raise inflation. It would take whatever fiscal and monetary policies were deemed necessary to achieve this (see A J-curve for Japan? and Japan’s three arrows).

Then on 4 July both the Bank of England and the ECB adopted forward guidance too. Worried that growth in the US economy would lead to an end to loose monetary policy before too long and that this would drive up interest rates worldwide, both central banks committed to keeping interest rates low for an extended period of time. Indeed, the ECB declared that the next movement in interest rates would more likely be down than up. Mario Draghi, the ECB president said that the ending of loose monetary policy is ‘very distant’.

The effect of this forward guidance has been to boost stock markets again. The hope is that by managing expectations in this way, the real economy will be affected too, with increased confidence leading to higher investment and faster economic growth.

Update (8/8/13)
With the publication of its August 2013 Inflation Report, the Bank of England clarified its approach to forward guidance. It was announced that Bank Rate would stay at the current historically low level of 0.5% ‘at least until the Labour Force Survey headline measure of unemployment has fallen to a threshold of 7%’. In his Inflation Report Press Conference opening remarks, Mark Carney, Governor of the Bank of England, also stated that:

While the unemployment rate remains above 7%, the MPC stands ready to undertake further asset purchases if further stimulus is warranted. But until the unemployment threshold is reached the MPC intends not to reduce the stock of asset purchases from the current £375 billion.

Nevertheless, the Bank reserved the right to abondon this undertaking under cirtain circumstances. As Mark Carney put it:

The Bank of England’s unwavering commitment to price stability and financial stability is such that this threshold guidance will cease to apply if material risks to either are judged to have arisen. In that event, the unemployment threshold would be ‘knocked out’. The guidance will remain in place only if, in the MPC’s view, CPI inflation 18 to 24 months ahead is more likely than not to be below 2.5%, medium-term inflation expectations remain sufficiently well anchored, and the FPC has not judged that the stance of monetary policy poses a significant threat to financial stability that cannot otherwise be contained through the considerable supervisory and regulatory policy tools of the various authorities. The two inflation knockouts ensure that the guidance remains fully consistent with our primary objective of price stability. The financial stability knockout takes full advantage of the new institutional structure at the Bank of England, ensuring that monetary and macroprudential policies coordinate to support a sustainable recovery. The knock-outs would not necessarily trigger an increase in Bank Rate – they would instead be a prompt for the MPC to reconsider the appropriate stance of policy.

Similarly, it is important to be clear that Bank Rate will not automatically be increased when the unemployment threshold is reached. Nor is 7% a target for unemployment. The rate of unemployment consistent with medium-term price stability – a rate that monetary policy can do little to affect – is likely to be lower than this. So 7% is merely a ‘way station’ at which the MPC will reassess the state of the economy, the progress of the economic recovery, and, in that context, the appropriate stance of monetary policy.

The articles in the updated section below consider the implications of this forward guidance and the caveat that the undertaking might be abondoned in certain circumstances.

Questions

  1. Is forward guidance a ‘rules-based’ or ‘discretion-based’ approach to monetary policy?
  2. Is it possible to provide forward guidance while at the same time pursuing an inflation target?
  3. If people know that central banks are trying to manage expectations, will this help or hinder central banks?
  4. Does the adoption of forward guidance by the Bank of England and ECB make them more or less dependent on the Fed’s policy?
  5. Why may forward guidance be a more effective means of controlling interest rates on long-term bonds (and other long-term rates too) than the traditional policy of setting the repo rate on a month-by-month basis?
  6. What will determine the likely success of forward guidance in determining long-term bond rates?
  7. Is forward guidance likely to make stock market speculation less destabilising?
  8. Is what ways is the ‘threshold guidance’ by the Bank of England likely to make the current expansionary stance of monetary policy more effective?
  9. Is 7% the ‘natural rate of unemployment’? Explain your reasoning.

Despite the prolonged stagnation in the UK, unemployment has not soared. In fact, over the past two years the ILO unemployment rate (see here for a definition) has fallen slightly – from 8.6% in October 2011 to around 8.0% today. What is more, the claimant count rate is considerably lower than the ILO rate – at around 4.4%.

Part of the reason for the relatively good unemployment figures is the rise in ‘zero-hours contracts’. These allow employers to cut the hours that people work without laying them off. The Office for National Statistics estimates that last year (2012) 250,000 people, or 0.84% of the workforce, were on such contracts.

But just what is meant by ‘zero-hours contracts’? According to the ONS:

People on zero-hours contracts are classified as being in employment regardless of the number of hours they actually worked during the survey reference week. This includes anyone who was not required to work any hours during the reference week whilst remaining on their current contract of employment. The continued existence of the contract of employment is the key determinant of their employment status in these situations.

If people are working less than they would like to, this is classified as underemployment, but such people do not appear in the unemployment statistics. Such contracts thus mask the true extent of surplus labour in the economy.

The Chartered Institute of Personnel and Development (CIPD) puts the figure much higher than the ONS. In the Summer 2013 issue of its Labour Market Outlook, it estimates that one million workers are on zero-hours contracts.

Many employers use such contracts, including many voluntary-sector and public-sector organisations, including the NHS, local councils and Buckingham Palace. They are also used by many small and medium-sized enterprises and many well-known large companies, such as Sports Direct, Amazon, JD Wetherspoon and Cineworld. It gives them the flexibility to adjust the hours they employ people. It allows them to keep people in employment when demand is low. It also makes them more willing to take on staff when demand rises, as it removes the fear of being over-staffed if demand then falls back.

But many workers dislike such contracts, which give them fewer employment rights and fewer hours than they would like to work. It also makes it difficult to budget when future income is uncertain. It also make credit and mortgages harder to obtain, as people have no guaranteed income. Another complaint is that companies may use the threat of lower hours as a tool to bully staff and get away with poorer working conditions.

In May of this year, the Business Secretary, Vince Cable, announced that he was setting up a review of zero hours contracts.

Note that zero hours are not the only form of flexible working. Other examples include: ‘self-employed’ workers, contracted separately for each job they do for a company; people paid largely or wholly on commission; on-call working; part-time working, where the hours are specified in advance, but where these are periodically re-negotiated; overtime; people producing a product or service for a company (perhaps at home), where the company varies the amount paid per unit according to market conditions.

The following videos and articles look at the issue in some detail: at the extent of the practice and at its benefits to employers and its costs (and some benefits) to workers. Both The Guardian and the BBC have an extensive range of articles on the topic.
