What will production look like in 20 years time? Will familiar jobs in both manufacturing and the services be taken over by robots? And if so, which ones? What will be the effect on wages and on unemployment? Will most people be better off, or will just a few gain while others get by with minimum-wage jobs or no jobs at all?

The BBC has been running a series looking at new uses for robots and whether they will take people’s jobs? This complements three reports: one by Boston Consulting one by Deloitte and an earlier one by Deloitte and Michael Osborne and Carl Frey from Oxford University’s Martin School. As Jane Wakefield, the BBC’s technology reporter states:

Boston Consulting Group predicts that by 2025, up to a quarter of jobs will be replaced by either smart software or robots, while a study from Oxford University has suggested that 35% of existing UK jobs are at risk of automation in the next 20 years.

Jobs at threat from machines include factory work, office work, work in the leisure sector, work in medicine, law, education and other professions, train drivers and even taxi and lorry drivers. At present, in many of these jobs machines work alongside humans. For example, robots on production lines are common, and robots help doctors perform surgery and provide other back-up services in medicine.

A robot may not yet have a good bedside manner but it is pretty good at wading through huge reams of data to find possible treatments for diseases.

Even if robots don’t take over all jobs in these fields, they are likely to replace an increasing proportion of many of these jobs, leaving humans to concentrate on the areas that require judgement, creativity, human empathy and finesse.

These developments raise a number of questions. If robots have a higher marginal revenue product/marginal cost ratio than humans, will employers choose to replace humans by robots, wholly or in part? How are investment costs factored into the decision? And what about industrial relations? Will employers risk disputes with employees? Will they simply be concerned with maximising profit or will they take wider social concerns into account?

Then there is the question of what new jobs would be created for those who lose their jobs to machines. According to the earlier Deloitte study, which focused on London, over 80% of companies in London say that over the next 10 years they will be most likely to take on people with skills in ‘digital know-how’, ‘management’ and ‘creativity’.

But even if new jobs are created through the extra spending power generated by the extra production – and this has been the pattern since the start of the industrial revolution some 250 years ago – will these new jobs be open largely to those with high levels of transferable skills? Will the result be an ever widening of the income gap between rich and poor? Or will there be plenty of new jobs throughout the economy in a wide variety of areas where humans are valued for the special qualities they bring? As the authors of the later Deloitte paper state:

The dominant trend is of contracting employment in agriculture and manufacturing being more than offset by rapid growth in the caring, creative, technology and business services sectors.

The issues of job replacement and job creation, and of the effects on income distribution and the balance between work and leisure, are considered in the following videos and articles, and in the three reports.

Jeremy Corbyn, the newly elected leader of the Labour Party, is proposing a number of radical economic policies. One that has attracted considerable attention is for a new form of QE, which has been dubbed ‘people’s quantitative easing’.

This would involve newly created money by the Bank of England being directly used to fund spending on large-scale housing, energy, transport and digital projects. Rather than the new money being used to purchase assets, as has been the case up to now, with the effect filtering only indirectly into aggregate demand and even more indirectly into aggregate supply, under the proposed scheme, both aggregate demand and aggregate supply would be directly boosted.

Although ‘conventional’ QE has worked to some extent, the effects have been uneven. Asset holders and those with large debts, such as mortgages, have made large gains from higher asset prices and lower interest rates. By contrast, savers in bank and building society accounts have seen the income from their savings decline dramatically. What is more, the indirect nature of the effects has meant time lags and uncertainty over the magnitude of the effects.

But despite the obvious attractiveness of the proposals, they have attracted considerable criticism. Some of these are from a political perspective, with commentators from the right arguing against an expansion of the state. Other criticisms focus on the operation and magnitude of the proposals

One is that it would change the relationship between the Bank of England and the government. If the Bank of England created money to fund government projects, that would reduce or even eliminate the independence of the Bank. Independence has generally been seen as desirable to prevent manipulation of the central bank by the government for short-term political gain. Those in favour of people’s QE argue that the money would be directed into a National Investment Bank, which would then make the investment allocation decisions. The central bank would still be independent in deciding the amount of QE.

This leads to the second criticism and that is about whether further QE is necessary at the current time. Critics argue that while QE of whatever type was justified when the economy was in recession and struggling to recover, now would be the wrong time for further stimulus. Indeed, it could be highly inflationary. The economy is currently expanding. If banks respond by increasing credit, the velocity of circulation of narrow money could rise and broad money supply grow, providing enough money to underpin a growing economy.

Many advocates of people’s QE accept this second point and see it as a contingency plan in case the economy fails to recover and further monetary stimulus is deemed necessary. If further QE is not felt necessary by the Bank of England, then the National Investment Bank could fund investment through conventional borrowing.

The following articles examine people’s QE and look at its merits and dangers. Given the proposal’s political context, several of the articles approach the issue from a very specific political perspective. Try to separate the economic analysis in the articles from their political bias.

In the late 2000s, Zimbabwe experienced hyperinflation. As a post on this site in January 2009 said, two estimates of the inflation rate were made: one of 5 sextillion per cent (5 and 21 zeros); the other of 6.5 quindecillion novemdecillion per cent (65 and 107 zeros). In January 2009, in a last attempt to save the Zimbabwean currency, a new series of banknotes was issued, including a Z$100 trillion note.

Prices were typically being adjusted at least twice a day and people had to carry large bags of money around even to buy a couple of simple items. The currency was virtually worthless. As the Guardian article below states:

Hyperinflation in Zimbabwe left pensions, wages and investments worthless and spread poverty as everyday items became unaffordable. It also caused severe cash shortages, because the government could not afford to print bank notes to keep pace with inflation.

The solution was to allow other currencies, mainly the US dollar and the South African rand, to be used alongside the local currency. Although the Zimbabwean currency was still legal tender, it effectively went out of use. Prices stabilised and since then inflation has been in single figures.

But many people still have stocks of the virtually worthless old currency, either in cash or in savings accounts. The Zimbabwean government has now said that it will exchange Zimbabwean dollar notes for US dollars at the rate of US$1 = Z$250tn (250,000,000,000). People have until September to do so. Up to now, they have mainly been used to sell as souvenirs to tourists! For people with Zimbabwean dollars in their bank accounts, they will get a minimum of US$5. For amounts beyond Z$175,000tn they will get an additional US dollar for each Z$35,000tn.

Historical examples of hyperinflation

As case study 15.5 in Economics 9e’s MyEconLab points out, several countries experienced hyperinflation after the First World War. In Austria and Hungary prices were several thousand times their pre-war level. In Poland they were over 2 million times higher, and in the USSR several billion times higher.

Germany in the 1920s
But even these staggering rates of inflation seem insignificant beside those of Germany. Following the chaos of the war, the German government resorted to printing money, not only to meet its domestic spending requirements in rebuilding a war-ravaged economy, but also to finance the crippling war reparations imposed on it by the allies in the Treaty of Versailles.

From mid 1921 the rate of monetary increase soared and inflation soared with it. By autumn 1923 the annual rate of inflation had reached a mind-boggling 7,000,000,000,000 per cent! As price increases accelerated, people became reluctant to accept money: before they knew it, the money would be worthless. People thus rushed to spend their money as quickly as possible. But this in turn further drove up prices. (The note shown above is in old billions, where a billion was a million million. So the note was for 50,000,000,000,000 marks.)

For many Germans the effect was devastating. People’s life savings were wiped out. Others whose wages were not quickly adjusted found their real incomes plummeting. Many were thrown out of work as businesses, especially those with money assets, went bankrupt. Poverty and destitution were widespread.

By the end of 1923 the German currency was literally worthless. In 1924, therefore, it was replaced by a new currency – one whose supply was kept tightly controlled by the government.

Serbia and Montenegro 1993–5
After the break-up of Yugoslavia in 1992, the economy of the remaining part of Yugoslavia (Serbia and Montenegro) collapsed. The government relied more and more on printing money to finance public expenditure. Prices soared.

The government attempted to control the inflation by imposing price controls. But these simply made production unprofitable and output fell further. The economy nosedived. Unemployment exceeded 30 per cent.

In October 1993, the government created a new currency, the new dinar, worth one million old dinars. In other words, six zeros were knocked off the currency. But this did not solve the problem. Between October 1993 and January 1994, prices rose by 5 quadrillion per cent (5 and fifteen zeros). Normal life could not function. Shops ran out of produce; savings were wiped out; barter replaced normal market activity.

At the beginning of January 1994 a ‘new new dinar’ was introduced, worth 1 billion new dinars. On 24 January this was replaced by a ‘novi dinar’ pegged 1 to 1 against the Deutsche Mark. This was worth approximately 13 million new new dinars. The novi dinar remained pegged to the Deutsche Mark and inflation was quickly eliminated.

The eurozone has been suffering from deflation: that is, negative inflation. But, the latest data show an increase in the rate of inflation in April from 0% to 0.3%. This is still a very low rate, with a return to deflation remaining a possibility (though perhaps unlikely); but certainly an improvement.

The eurozone economy has been stagnant for some time but the actions of the European Central Bank (ECB) finally appear to be working. Prices across the eurozone have risen, including services up by 1.3%, food and drink up by 1.2% and energy prices, albeit still falling, but at a slower rate. All of this has helped to push the annual inflation rate above 0%. For many, this increase was bigger than expected. Howard Archer, Chief European Economist at HIS Global Insight said:

“Renewed dips into deflation for the eurozone are looking increasingly unlikely with the risks diluted by a firming in oil prices from their January lows, the weakness of the euro and improved eurozone economic activity.”

Economic policy in the eurozone has focused on stimulating the economy, with interest rates remaining low and a €1.1 trillion bond-buying programme by the ECB. But, why is deflation such a concern? We know that one of the main macroeconomic objectives of a nation is low and stable inflation. If prices are low (or even falling) is it really as bad as economists and policy-makers suggest?

The problem of deflation occurs when people expect prices to continue falling and thus delay spending on durables, hoping to get the products cheaper later on. As such, consumption falls and this puts downward pressure on aggregate demand. This decision by consumers to put off spending will cause aggregate demand to shift to the left, thus pushing national income down, creating higher unemployment and adding to problems of economic stagnation. If this expectation continues, then so will the inward shifts in AD. In the eurozone, this has been a key problem, but it now appears that aggregate demand has stopped falling and is now slowly recovering, together with the economy.

It is important to note how interdependent all aspects of an economy are. The euro responded as news of better inflation data emerged, together with expectations of a Greek deal being reached. Enrique Diaz-Alvarez, chief risk officer at Ebury said:

“The move [rise in euro] got going with the big upside surprise in eurozone inflation data — especially core inflation, which bounced up from 0.6 per cent to 0.9 per cent. This is exactly what the ECB wants to see, as it is proof that QE is having the desired effect and removes the threat of deflation in the eurozone from the foreseeable future.”

One of the key factors that has kept inflation down in the eurozone (and also the UK) is falling oil prices. It is for this reason that many have been suggesting that this type of deflation is not bad deflation. With oil prices recovering, the general price level will also recover and so economies will follow suit. The following articles consider the fortunes of the eurozone.

  1. What is the difference between the 0.3% and 0.9% figures quoted for inflation in the eurozone?
  2. What is deflation and why is it such a concern?
  3. Illustrate the impact of falling consumer demand in an AD/AS diagram.
  4. How has the ECB’s QE policy helped to tackle the problem of deflation? Do you think that this programme needs to continue or now the economy has begun to improve, should the programme end?
  5. To what extent is the economic stagnation in the eurozone a cause for concern to countries such as the UK and USA? Explain your answer.
  6. Why has the euro risen, following news of this positive inflation data?

The CPI index fell by 0.1% in the 12 months to April 2015. This is partly the result of lower air and sea fares, as the upward ‘blip’ in these fares at Easter last year was not present in mid-April this year as Easter fell outside the period when the statistics are collected. What is more significant is that fuel, commodity and retail food prices have fallen over the past 12 months, and the exchange rate has risen, especially against the euro.

But how do we define what’s happened and how significant is it? It might seem highly significant as it’s the first time in 55 years that the CPI has fallen over a 12-month period. In fact, the effect is likely to be temporary, as fuel prices are now rising again and commodity prices generally are beginning to rise too. What is more, the pound seems to have peaked against the euro. Thus although aggregate demand remains relatively dampened, the main causes of falling prices and potential rises in the coming months are largely to be found on the cost side. This then brings us on to the definition of a falling CPI.

A falling CPI over a 12-month period can be defined as negative inflation. This is unambiguous. But is this ‘deflation’? The problem with the term ‘deflation’ is that it is ambiguous. On the one hand it can be defined simply as negative inflation. In that case, by definition, the UK has experienced deflation. But on the other, it is used to describe a situation of persistent falling prices as a result of declining aggregate demand.

If an economy suffers from deflation in this second sense, the problem can be very serious. Persistent falling prices are likely to discourage consumers from spending on durables (such as fridges, TVs, cars and furniture) and firms from buying capital equipment. After all, why buy an item now if, by waiting, you can get it cheaper later on? This mentality of waiting to spend leads to falling aggregate demand and hence falling output. It also leads to even lower prices. In other words deflation can get worse: a deflationary spiral.

If we define deflation in this second, much more serious sense, then the UK is not suffering deflation – merely temporary negative inflation. In fact, with prices now falling (slightly) and wages rising at around 2% per year, there should be an increase in aggregate demand, which will help to drive the recovery.
