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 In other cases, items are removed as they become outdated or obsolete with technology changing.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.

Many UK coal mines closed in the 1970s and 80s. Coal extraction was too expensive in the UK to compete with cheap imported coal and many consumers were switching away from coal to cleaner fuels. Today many shale oil producers in the USA are finding that extraction has become unprofitable with oil prices having fallen by some 50% since mid-2014 (see A crude indicator of the economy (Part 2) and The price of oil in 2015 and beyond). So is it a bad idea to invest in fossil fuel production? Could such assets become unusable – what is known as ‘stranded assets‘?
In a speech on 3 March 2015, Confronting the challenges of tomorrow’s world, delivered at an insurance conference, Paul Fisher, Deputy Governor of the Bank of England, warned that a switch to both renewable sources of energy and actions to save energy could hit investors in fossil fuel companies.
‘One live risk right now is of insurers investing in assets that could be left ‘stranded’ by policy changes which limit the use of fossil fuels. As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.
… As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.’
Much of the known reserves of fossil fuels could not be used if climate change targets are to be met. And investment in the search for new reserves would be of little value unless they were very cheap to extract. But will climate change targets be met? 
That is hard to predict and depends on international political agreements and implementation, combined with technological developments in fields such as clean-burn technologies, carbon capture and renewable energy. The scale of these developments is uncertain. As Paul Fisher said in his speech:
‘Tomorrow’s world inevitably brings change. Some changes can be forecast, or guessed by extrapolating from what we know today. But there are, inevitably, the unknown unknowns which will help shape the future. … As an ex-forecaster I can tell you confidently that the only thing we can be certain of is that there will be changes that no one will predict.’
The following articles look at the speech and at the financial risks of fossil fuel investment. The Guardian article also provides links to some useful resources.

The articles linked below look at the dangers of deflation and policies of central banks to counter it.
Deflation in economics has three meanings. The first is falling prices: i.e. negative inflation. The second, more traditional meaning, is a fall in real aggregate demand, resulting in lower output, higher unemployment and lower inflation – and quite possibly an actual fall in the price level. These first two definitions describe what is generally seen as an undesirable situation. The third is a slowing down in the growth of real aggregate demand, perhaps as a result of a deliberate act of fiscal and/or monetary policy. This third meaning could describe a desirable situation, where unsustainable growth is reduced and inflation is reduced from an above-target level.
Here we focus on the first definition. The first two articles look at the dangers of a fall in the price level. The chart below shows falling inflation, although not actually deflation, in China, France, Germany and the UK (click here for a PowerPoint). Several European countries, however, are experiencing actual deflation. These include: Greece, Spain, Hungary, Poland and Sweden. Inflation in the eurozone for 2014 is expected to be a mere 0.5%.
The most obvious danger of deflation (or expected deflation) is that people will delay spending on durable goods, such as cars, furniture and equipment, hoping to buy the items cheaper later. 
The result could be a fall in aggregate demand and a fall in output and employment.
For retailers, this is all spelling Christmas doom. Already the runup to the most crucial time of the year for shops is being characterised by a game of chicken. Shoppers are wondering how long they can leave their festive buying in the hope of late bargains.
Interest rates may be low, but for people with debts, this is being offset by the fact that inflation is no longer reducing the real value of that debt. For people with credit card debt, personal loans and most mortgages, the interest rate they pay is significantly above the rate of inflation. In other words, the real interest rate on their debt is still significantly positive. This may well discourage people from borrowing and spending, further dampening aggregate demand. And, with a Bank Rate of just 0.5%, there is virtually no scope for lowering the official interest rate further.
At least in the UK, economic growth is now positive – for the time being at any rate. The danger is becoming more serious, however, in many eurozone countries, which are already back in recession or close to being so. The ECB, despite its tentative steps to ease credit conditions, it moving closer to the day when it announces full-blown quantitative easing and buys sovereign bonds of eurozone countries. The Bank of Japan has already announced that it is stepping up it QE programme – a vital ingredient in getting Abenomics back on track and pulling Japan out of its latest recession.
In the USA, by contrast, there is little danger of deflation, as the US economy continues to grow strongly. The downside of this, has been a large rise in consumer debt (but not mortgages) – the ingredients of a possible future bubble and even a new financial crisis.

Questions
- What are (a) the desirable and (b) the undesirable consequences of deflation? Does the answer depend on how deflation is defined?
- What is meant by a ‘deflationary gap’? In what sense is ‘deflationary’ being used in this term?
- Why have oil prices been falling? How desirable are these falls for the global economy?
- Is there an optimal rate of inflation? If so, how would this rate be determined?
- The chart shows that inflation in Japan is likely to have risen in 2014. This in large part is the result to a rise in the sales tax earlier this year. If there is no further rise in the sales tax, which there will probably not be if Mr Abe’s party wins the recently called election, what is likely to be the effect of the 2014 tax rise on inflation in 2015?
- If the Bank Rate is below the rate of inflation, why are people facing a positive real rate of interest? Does this apply equally to borrowers and savers?

Following the recession of 2008/9, the UK has engaged in four rounds of quantitative easing (QE) – the process whereby the central bank increases the money supply by purchasing government bonds, and possibly other assets, on the open market from various institutions. The final round was announced in July 2012, bringing the total assets purchased to £375bn. As yet, however, there are no plans for quantitative tightening – the process of the Bank of England selling some of these assets, thereby reducing money supply.
The aim of QE has been to stimulate aggregate demand. Critics claim, however, that the effect on spending has been limited, since the money has not gone directly to consumers but rather to the institutions selling the assets, who have used much of the money to buy shares, bonds and other assets. Nevertheless, with banks having to strengthen their capital base following the financial crisis, QE has helped then to achieve this without having to make even bigger reductions in lending.
The Bank of England now reckons that the recovery is sufficiently established and there is, therefore, no need for further QE.
This is also the judgement of the Federal Reserve about the US economy, which experienced annual growth of 3.5% in the third quarter of 2014. The IMF predicts that US growth will be around 3% for the next three years.
The Fed has had three rounds of QE since the financial crisis, but in October 2014 called an end to the process. Since the start of this year, it has been gradually reducing the amount it injects each month from $85bn to $15bn. The total bond purchases over the past five years have been some $3.6tn, bringing the Fed’s balance sheet to nearly $4.5tn.
But as QE comes to an end in the USA, Japan is expanding its programme. On 31 October, the Bank of Japan announced that it would increase its asset purchases from ¥60-70tn per year to ¥80tn (£440bn). The Japanese government and central bank are determined to boost economic growth in Japan and escape the two decades of deflation and stagnation. The Tokyo stock market rose by some 8% in the week following the announcement and the yen fell by more than 5% against the dollar.
And the European Central Bank, which has not used full QE up to now, looks as if it is moving in that direction. 
In October, it began a programme of buying asset-backed securities (ABSs) and covered bonds (CBs). These are both private-sector securities: ABSs are claims against non-financial companies in the eurozone and CBs are issued by eurozone banks and other financial institutions.
It now looks as if the ECB might take the final step of purchasing government bonds. This is probably what is implied by ECB President Mario Draghi’s statement after the 6 November meeting of the ECB that the ground was being prepared for “further measures to be implemented, if needed”.
But has QE been as successful as its proponents would claim? Is it the solution now to a languishing eurozone economy? The following articles look at these questions.

House prices have been rising strongly in London. According to the Halifax House Price index, house prices in London in the first quarter of 2014 were 15.5% higher than a year ago. This compares with 8.7% for the UK as a whole, 1.3% for the North of England and –1.5% for Scotland. CPI inflation was just 1.6% for the same 12-month period.
The London housing market has been stoked by rising incomes in the capital, by speculation that house prices will rise further and by easy access to mortgages, fuelled by the government’s Help to Buy scheme, which allows people to put down a deposit of as little as 5%. House prices in London in the first quarter of 2014 were 5.3 times the average income of new mortgage holders, up from 3.5 times in the last quarter of 2007, just before the financial crisis.
Concerns have been growing about increasing levels of indebtedness, which could leave people in severe financial difficulties if interest rates were to rise significantly. There are also concerns that an increasing proportion of people are being priced out of the housing market and are being forced to remain in the rental sector, where rents are also rising strongly.
But how can the housing market in London be dampened without dampening the housing market in other parts of the country where prices are barely rising, and without putting a break on the still relatively fragile recovery in the economy generally?
The Governor of the Bank of England has just announced two new measures specific to the housing market and which would apply particularly in London.
The first is to require banks to impose stricter affordability tests to new borrowers. Customers should be able demonstrate their ability to continue making their mortgage payments if interest rates were 3 percentage points higher than now.
The second is that mortgage lenders should restrict their lending to 4½ times people’s income for at least 85% of their lending.
Critics are claiming that these measures are likely to be insufficient. Indeed, Vince Cable, the Business Secretary, has argued for a limit of 3½ times people’s income. Also banks are already typically applying a ‘stress test’ that requires people to be able to afford mortgage payments if interest rates rose to 7% (not dissimilar to the Bank of England’s new affordability test).
The videos and articles look at the measures and consider their adequacy in dealing with what is becoming for many living in London a serious problem of being able to afford a place to live. They also look at other measures that could have been taken.
