What’s the outlook for the global economy?

The International Monetary Fund has just published its six-monthly World Economic Outlook (WEO). The publication assesses the state of the global economy and forecasts economic growth and other indicators over the next few years. So what is this latest edition predicting?

Well, once again the IMF had to adjust its global economic growth forecasts down from those made six months ago, which in turn were lower than those made a year ago. As Larry Elliott comments in the Guardian article linked below:

Every year, economists at the fund predict that recovery is about to move up a gear, and every year they are disappointed. The IMF has over-estimated global growth by one percentage point a year on average for the past four years.

In this latest edition, the IMF is predicting that growth in 2015 will be slightly higher in developed countries than in 2014 (2.0% compared with 1.8%), but will continue to slow for the fifth year in emerging market and developing countries (4.0% in 2015 compared with 4.6% in 2014 and 7.5% in 2010).

In an environment of declining commodity prices, reduced capital flows to emerging markets and pressure on their currencies, and increasing financial market volatility, downside risks to the outlook have risen, particularly for emerging market and developing economies.

So what is the cause of this sluggish growth in developed countries and lower growth in developing countries? Is lower long-term growth the new norm? Or is this a cyclical effect – albeit protracted – with the world economy set to resume its pre-financial-crisis growth rates eventually?

To achieve faster economic growth in the longer term, potential national output must grow more rapidly. This can be achieved by a combination of more rapid technological progress and higher investment in both physical and human capital. But in the short term, aggregate demand must expand sufficiently rapidly. Higher short-term growth will encourage higher investment, which in turn will encourage faster growth in potential national output.

But aggregate demand remains subdued. Many countries are battling to cut budget deficits, and lending to the private sector is being constrained by banks still seeking to repair their balance sheets. Slowing growth in China and other emerging economies is dampening demand for raw materials and this is impacting on primary exporting countries, which are faced with lower exports and lower commodity prices.

Quantitative easing and rock bottom interest rates have helped somewhat to offset these adverse effects on aggregate demand, but as the USA and UK come closer to raising interest rates, so this could dampen global demand further and cause capital to flow from developing countries to the USA in search of higher interest rates. This will put downward pressure on developing countries’ exchange rates, which, while making their exports more competitive, will make it harder for them to finance dollar-denominated debt.

As we have seen, long-term growth depends on growth in potential output, but productivity growth has been slower since the financial crisis. As the Foreword to the report states:

The ongoing experience of slow productivity growth suggests that long-run potential output growth may have fallen broadly across economies. Persistently low investment helps explain limited labour productivity and wage gains, although the joint productivity of all factors of production, not just labour, has also been slow. Low aggregate demand is one factor that discourages investment, as the last World Economic Outlook report showed. Slow expected potential growth itself dampens aggregate demand, further limiting investment, in a vicious circle.

But is this lower growth in potential output entirely the result of lower demand? And will the effect be permanent? Is it a form of hysteresis, with the effect persisting even when the initial causes have disappeared? Or will advances in technology, especially in the fields of robotics, nanotechnology and bioengineering, allow potential growth to resume once confidence returns?

Which brings us back to the short and medium terms. What can be done by governments to stimulate sustained recovery? The IMF proposes a focus on productive infrastructure investment, which will increase both aggregate demand and aggregate supply, and also structural reforms. At the same time, loose monetary policy should continue for some time – certainly as long as the current era of falling commodity prices, low inflation and sluggish growth in demand persists.

Down down deeper and down, or a new Status Quo?

If you asked virtually any banker or economist a few years ago whether negative (nominal) interest rates were possible, the answer would almost certainly be no.

Negative real interest rates have been common at many points in time – whenever the rate of inflation exceeds the nominal rate of interest. People’s debts and savings are eroded by inflation as the interest due or earned does not keep pace with rising prices.

But negative nominal rates? Surely this could never happen? It was generally believed that zero (or slightly above zero) nominal rates represented a floor – ‘a zero lower bound’.

The reasoning was that if there were negative nominal rates on borrowing, you would effectively be paid by the bank to borrow. In such a case, you might as well borrow as much as you can, as you would owe less later and could pocket the difference.

A similar argument was used with savings. If nominal rates were negative, savers might as well withdraw all their savings from bank accounts and hold them as cash (perhaps needing first to buy a safe!) Given, however, that this might be inconvenient and potentially costly, some people may be prepared to pay banks for looking after their savings.

Central bank interest rates have been hovering just above zero since the financial crisis of 2008. And now, some of the rates have turned negative (see chart above). The ECB has three official rates:

The interest rate on the main refinancing operations (MRO), which provide the bulk of liquidity to the banking system.
The rate on the deposit facility, which banks may use to make overnight deposits with the Eurosystem.
The rate on the marginal lending facility, which offers overnight credit to banks from the Eurosystem.

The first of these is the most important rate and remains above zero – just. Since September 2014, it has been 0.05%. This rate is equivalent to the Bank of England’s Bank Rate (currently still 0.5%) and the Fed’s Federal Funds Rate (currently still between 0% and 0.25%).

The third of the ECB’s rates is currently 0.3%, but the second – the rate on overnight deposits in the ECB by banks in the eurozone – is currently –0.2%. In other words, banks have to pay the ECB for making these overnight deposits (deposits that can be continuously rolled over). The idea has been to encourage banks to lend rather than simply keeping unused liquidity.

In Nordic countries, the experiment with negative rates has gone further. With plenty of slack in the Swedish economy, negative inflation and an appreciating krona, the Swedish central bank – the Riksbank – cut its rates below zero.

Many City analysts believe that the Riksbank will continue cutting, reducing its key interest rate to minus 0.5% by the end of the year [it is currently 0.35%]. Switzerland’s is already deeper still, at minus 0.75%, while Denmark and the eurozone have joined them as members of the negative zone.

But the nominal interest rate on holding cash is, by definition, zero. If deposit rates are pushed below zero, then will more and more people hold cash instead? The hope is that negative nominal interest rates on bank accounts will encourage people to spend. It might, however, merely encourage them to hoard cash.

The article below from The Telegraph looks at some of the implications of an era of negative rates. The demand for holding cash has been increasing in many countries and, along with it, the supply of banknotes, as the chart in the article shows. Here negative interest are less effective. In Nordic countries, however, the use of cash is virtually disappearing. Here negative interest rates are likely to be more effective in boosting aggregate demand.

The rise of the machines

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.

People’s quantitative easing

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.

A remnant of hyperinflation in Zimbabwe

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.

Eurozone: positive inflation

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.

Negative inflation or deflation? What’s the UK experiencing?

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.

Insolvencies down – lessons learned?

Insolvencies in England and Wales have fallen to their lowest level since 2005, official records show. The Insolvency Service indicates that bankruptcy, individual voluntary arrangements and debt relief orders have fallen, with the largest and worst form of bankruptcy falling by 22.5 per cent compared to the same period in 2014. There has also been a fall in corporate insolvencies back to pre-crisis levels.

The British economy is recovering and despite an increase in consumer borrowing of £1.2 billion from February to March, which is the biggest since the onset of the credit crunch, the number of people in financial difficulty and living beyond their means has fallen. However, there are also suggestions that the number could begin to creep up in the future and we are still seeing a divide between the north and south of England in terms of the number of insolvencies.

There are many factors that could explain such a decline in insolvencies. Perhaps it is the growth in wages, in part due the recovery of the economy, which has enabled more people to forgo borrowing or enabled them to repay any loan more comfortably. Lower inflation has helped to reduce the cost of living, thereby increasing the available income to repay any loans. Interest rates have also remained low, thus cutting the cost of borrowing and the repayments due.

But, another factor may simply be that lending is now more closely regulated. Prior to the financial crisis, huge amounts of money were being lent out, often to those who had no chance of making the repayments. More stringent affordability checks by lenders may have a large part to play in reducing the number of insolvencies. President of R3, the insolvency practitioner body, Phillip Sykes said:

“It may be too early to draw conclusions but demand could be falling as a result of low interest rates, low inflation and tighter regulation. This trend is worth watching.”

Mark Sands, from Baker Tilly added to this, noting that fewer people were now in financial difficulty.

“As well as this, we are seeing lower levels of personal debt and fewer people borrowing outside of their means due to more stringent affordability checks by creditors.”

Whatever the main reason behind the data, it is certainly a positive indicator, perhaps of economic recovery, or that at least some have learned the lessons of the financial crisis. The following articles consider this topic.

Fuelling the absence of inflation

The latest inflation figures, as detailed in February’s Consumer Price Inflation Statistical Bulletin, show that the annual rate of CPI inflation hit zero in February. This is down from 0.3 per cent in January. While inflation is now well outside the 1-3 per cent target range that the Bank of England is charged with meeting, perhaps a more pertinent question is whether the UK is teetering on the brink of deflation – and the risks that may carry.

To get a better sense of the latest inflation picture we need to delve deeper into the numbers and look at the patterns in the prices that make up the overall Consumer Price Index. Interestingly, these shows that five of the 12 principal product groups that make up the index are currently experiencing price deflation.

As explained in Consumer Price Inflation: The 2015 Basket of Goods and Services, produced by the ONS, around 180,000 prices quotations are collected each month for around 700 representative items. These goods and services fall into one of 12 broad product groups. These include, for example, food and non-alcoholic beverages and transport.

The items included in each of the 12 product groups are reviewed once a year so that the chosen items remain representative of today’s spending patterns. A monthly price index is calculated for these 12 broad groupings, known as divisions, and for sub-categories of these. For example meat is a category within food and non-alcoholic beverages. The overall CPI is a weighted average of the 12 broad groupings.

The annual rate of CPI inflation in February 2015 was zero. This means that the price of the representative basket of goods and services was unchanged from its level in February 2014. As Chart 1 shows (click here for a PowerPoint of the chart), the annual rate of CPI inflation series goes back to January 1989 and this is the first time it has fallen to zero. Its average over this period is in fact 2.7 per cent. The recent fall is quite stark with the rate of CPI inflation in June 2013 close to the top-end of the Bank of England’s target range at 2.9 per cent.

Of the 12 product groups, five constitute 10 per cent or more of the overall weight of the CPI index. These weights are dependent on the relative level of expenditure comprised by each division.

Chart 2 shows the annual rates of inflation for these five groups (click here for a PowerPoint of the chart). The most heavily-weighted component is transport (14.9%), which includes the price of fuel and passenger transport. Here we observe deflation with prices 2.7 per cent lower year-on-year in February. This is the fourth consecutive month where its annual rate of price inflation has been negative.

The second most heavily-weighted component within the CPI index is recreation and culture (14.7%), which includes games, toys and audio-visual equipment. Here too we see the emergence of deflation. In February 2015 prices were 0.8 per cent lower than in February 2014. Deflation is most prevalent in the fifth most heavily-weighted component (11.0%): food and non-alcoholic drinks. The price for this division of the CPI was 3.3 per cent lower in February 2015 as compared with February 2014. In nine of the last ten months the price of food and non-alcoholic drinks, helped by aggressive price competition in the grocery sector, has been lower year-on-year.

February also saw a negative annual rate of inflation emerge for the first time in the CPI division capturing furniture and household equipment and appliances (-0.3 per cent). Further, miscellaneous services, which include personal care and personal effects (e.g. jewellery) saw an annual rate of deflation for the eight consecutive month. The annual rate of inflation for miscellaneous services stood at -0.4 per cent in February. However, February did see an upturn in price inflation for clothing and footwear with prices 1.7 per cent higher than a year earlier while the price of alcohol and tobacco was 3.8 per cent higher year-on-year.

The detailed inflation numbers do reveal the extent to which many CPI divisions are already characterised by deflation. It is interesting to note that in A Comparison of Independent Forecasts published monthly by HM Treasury, the forecast for the final quarter of 2015 is for the annual rate of CPI inflation to be running at 0.8 per cent. An important reason for this is that the effect of falling fuel prices from November 2014 will begin to drop out of the year-on-year inflation rate calculations. The removal of this effect should help to prevent the specter of deflation provided that peoples’ inflationary expectations remain anchored, i.e. exhibit stickiness. If these were to be revised down, however, this would further contribute to downward pressure on prices since input price inflation – including wage inflation – would again be expected to fall.

Your basket: ins and outs

The rate of inflation in the UK is measured using the Consumer Prices Index (CPI). This is made up of a basket of goods and the ONS updates this ‘basket’ each year to ensure it is representative of what the average UK household buys. The basket contains 703 items, with 110,000 individual prices collected each month.

In past years, items such as lip gloss have been added to the basket of goods, together with tablet computers and teenage fiction. In the recent update by the ONS, e-cigarettes have been added, together with specialist ‘craft’ beers and music streaming. On the other hand, other items have been removed, as the world changes. For example, during the recession, champagne was removed as an item that the representative household was no longer buying. In other cases, items are removed as they become outdated or obsolete with technology changing. This is the case with satellite navigation systems. As people turn to using their smartphones to navigate their way from A to B, satellite navigation systems are no longer seen as an item bought by the representative household.

The UK inflation rate is at an all-time low of 0.3% and there have been concerns that it may become negative, meaning we enter the world of deflation. However, if this does occur, many suggest that it is not bad deflation, as it is being driven by the extremely low oil prices. No matter what the inflation rate, the ONS will always continue to update the basket of goods that calculates inflation. It is therefore essential that these changes are made each year, as consumer buying habits do fluctuate considerably, as income changes, technology changes and general tastes change. The following articles consider what’s in and what’s out.
