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?
- In what sense is there a cultural revolution at the Bank of England?
Much of the east coast of England is subject to tidal flooding. One such area is the coastline around the Wash, the huge bay between Norfolk and Lincolnshire. Most of the vulnerable shorelines are protected by sea defences, usually in the form of concrete walls or earth embankments, traditionally paid for by the government. But part of the Norfolk shoreline is protected by shingle banks, which require annual maintenance.
Full government funding for maintaining these banks ended in 2013. According to new government rules, only projects that provide at least £8 of benefits for each £1 spent would qualify for such funding to continue. The area under question on the Norfolk cost of the Wash does not qualify.

Between 2013 and 2015 the work on the shingle banks is being paid for by the local council charging levies. After that, the plan is for a partnership-funding approach, where the government will make a (small) contribution as long as the bulk of the funding comes from the local community. This will involve setting up a ‘community interest company’, which will seek voluntary contributions from local residents, landowners and businesses.
Sea defences are a public good, in that it is difficult to exclude people benefiting who choose not to pay. In other words, there is a ‘free rider’ problem. However, in the case of the Wash shoreline in question, one borough councillor, Brian Long, argues that it might be possible to maintain the flood defences to protect those who do contribute while ignoring those who do not.
Not surprisingly, many residents and businesses argue that the government ought to fund the defences and, if it does have to be financed locally, then everyone should be required to pay their fair share.

Questions
- What are the two main features of a public good? Are sea defences a pure public good?
- Is there a moral hazard if people choose to live in a coastal area that would be subject to flooding without sea defences?
- Who is the ‘public’ in the case of sea defences? Is it the whole country, or the local authority or just all those being protected by the defences?
- What are the problems with relying on voluntary contributions to fund, or partly fund, sea defences? How could the free-rider problem be minimised in such a funding model?
- Discuss the possible interpretations of ‘equity’ when funding sea defences.
- If ‘flood defences could be built or maintained to protect those who do contribute while ignoring those who do not’, does this mean that such defences are not a public good?
- Find out how sea defences are funded in The Netherlands. Should such a funding model be adopted in the UK?
Since coming to office two years ago, Shinzo Abe’s government has been determined to revive the Japanese economy. The policy has involved ‘three arrows‘: expansionary fiscal policy, expansionary monetary policy and supply-side reforms. But figures just out show that the Japanese economy is back in recession. The economy shrank by 0.4% in quarter 3, having shrunk by 1.9% in quarter 2.
This has come as a huge disappointment for Mr Abe, who has staked his political reputation on escaping from deflation and achieving sustained economic growth. In response, he has called a general election to put a revised economic plan to the electorate.

The main cause of the reversal into recession has been an increase in the sales tax on all goods, which has dampened spending. The tax rise, planned by the previous government, was to help reduce the deficit and start tackling the huge public-sector debt, which, at over 230% of GDP, is by far the highest in the developed world. Another rise in sales tax is due in October 2015 – from 8% to 10%. Mr Abe hopes to cancel the rise and it is this that he may put to the electorate.
So what is the outlook for Japan? Will quarter 4 show economic growth, or will pessimism have set in? Will the Bank of Japan introduce even more quantitative easing, or will it wait for the latest increase in QE to take effect (see the blog post, All eased out: at least for the USA and UK)?
The following articles look at the implications of the latest news, both for Japan and globally, and at the options for the government and central bank.
