Rising inflation: not normally a cause for celebration, but that’s not the case for Japan. Having been subject to the spectre of deflation for many years, the 22-year high for the CPI at 2.7% is a welcome figure, even it is slightly lower than expected. This surge in prices is partly the result of a growth in domestic demand and a sign, therefore, that output will expand in response to the rise in demand.

The Japanese economy has experienced largely stagnant growth for two decades and a key cause has been falling prices. Although consumers like bargains, this has been problematic for this large economy. Deflation creates continuously falling prices and this means consumers hold back from purchasing durable goods, preferring to wait until prices have fallen further.

In the blog, Japan’s recovery, we looked at inflation data showing Japanese consumer prices growing at a faster rate than expected. This ‘positive’ trend has continued.

When it comes to inflation, expectations are crucial. If people think prices will rise in the future, they are more likely to buy now to get the lower price. This can therefore help to stimulate aggregate demand and it is this that has been the target for Japan. Part of the growth in the CPI is down to the sales tax rise from 5% to 8%. This was the first time in 17 years that the sales tax had increased. Further increases in it are expected in 2015. There were concerns about the impact of this rise, based on the depression that followed the last rise back in 1997, but so far the signs seem good.

Monetary easing was a key component in ending the downward trajectory of the Japanese economy and, following the sales tax rise, many believe that another round of monetary easing may be needed to counter the effects and create further growth in the economy and in the CPI. As the Bank of Japan Governor said:

There are various ways to adjust policy. We will decide what among these measures is appropriate depending on economic and price developments at the time … For now, we can say Japan is making steady progress toward achieving 2 per cent inflation.

One of the ‘three arrows‘ of the government’s policy has been to boost government spending, which should directly increase aggregate demand. Furthermore, with signs of the CPI rising, consumers may be encouraged to spend more, giving a much needed boost to consumption. The economy is certainly not out of the woods, but appears to be on the right path. The following articles consider the Japanese economy.

The growth of China over the past decade has been quite phenomenal, with figures recorded in double-digits. However, in the aftermath of the recession, growth has declined to around 7% – much higher than Western economies are used to, but significantly below the ‘norm’ for China. (Click here for a PowerPoint of the chart.)

The growth target for this year is 7.5%, but there appear to be some concerns about China’s ability to reach this figure and this has been emphasised by a recent Chinese policy.

A mini-stimulus package has been put in place, with the objective of meeting the 7.5% growth target. Government expenditure is a key component of aggregate demand and when other components of AD are lower than expected, boosting ‘G’ can be a solution. However, it’s not something that the Chinese government has had to do in recent years and the fact that this stimulus package has been put in place has brought doubts over China’s economic performance to the forefront , but has confirmed its commitment to growth. Mizuho economist, Shen Jianguang, said:

It’s very obvious that the leaders feel the need to stabilise growth…Overall, the 7.5 per cent growth target means that the government still cares a lot about economic growth.

Data suggest that growth in China is relatively weak and there are concerns that the growth target will be missed, hence the stimulus package. In the aftermath of the 2008 financial crisis, there was a large stimulus package in place in China. This latest investment by the government is in no way comparable to the size of the 2008 package, but instead will be on a smaller and more specific scale. Mark Williams of Capital Economics said:

It’s a bit of a rerun of what we saw last year – something less than a stimulus package and more of piecemeal measures to ensure they reach their growth target.

It is the construction of public housing and railways that will be the main areas of investment this time round. A sum of $120–180bn per year will be available for railway construction and $161bn for social housing, and tax breaks are being extended for small businesses.

The 2008 stimulus package saw debt increase to some 200% of GDP, which did cause growing concerns about the reliance on debt. However, this latest package will be financed through the issue of bonds, which is much more similar to how market economies finance spending.

The fact that the government has had to intervene with such a stimulus package is, however, causing growing concerns about the level of debt and the future of this fast growing economy, though the new method of financing is certainly seen as progress.

It should be noted that a decline in growth for China is not only concerning for China itself, but is also likely to have adverse consequences other countries. In the increasingly interdependent world that we live in, Western countries rely on foreign consumers purchasing their exports, and in recent years it has been Chinese consumers that have been a key component of demand. However, a decline in growth may also create some benefits – resources may not be used up as quickly and prices of raw materials and oil in particular may remain lower.

It is certainly too early for alarm bells, but the future of China’s growth is less certain than it was a decade ago. The following articles consider this issue.

The price of road fuel is falling. Petrol and diesel prices in the UK are now at their lowest level since February 2011. The average pump price for a litre of unleaded petrol has fallen to 130.44p in November – down nearly 8p per litre since September.

According to the AA, the reduction in price equates to a fall in the average monthly expenditure on petrol of a two-car family of £14.49 – down from £252.54 to £238.05. This saving can be used for spending on other things and can thus help to boost real aggregate demand. The fall in price has also helped to reduce inflation.

But will lower fuel prices lead to a rise in fuel consumption? In other words, will some of the savings people make when filling up be used for extra journeys? If so, how much extra will people consume? This, of course depends on the price elasticity of demand.

The following articles explain why the price of road fuel has fallen and look at its consequences.

A constant feature of the UK economy (and of many other Western economies) has been record low interest rates. Since March 2009, Bank Rate has stood at 0.5%. Interest rates have traditionally been used to keep inflation on target, but more recently their objective has been to stimulate growth. However, have these low interest rates had a negative effect on the business environment?

Interest rates are a powerful tool of monetary policy and by affecting many of the components of aggregate demand, economic growth can be stimulated. This low-interest rate environment is an effective tool to stimulate consumer spending, as it keeps borrowing costs low and in particular can keep mortgage repayments down. However, this policy has been criticised for the harm it has been doing to savers – after all, money in the bank will not earn an individual any money with interest rates at 0.5%! Furthermore, there is now a concern that such low interest rates have led to ‘zombie companies’ and they are restricting the growth potential and recovery of the economy.

A report by the Adam Smith Institute suggests that these ‘zombie companies’ have emerged in part by the low-interest environment and are continuing to absorb resources, which could otherwise be re-allocated to companies with more potential, productivity and a greater contribution to the economic recovery. During a recession, there will undoubtedly be many business closures, as aggregate demand falls, sales and profits decline until eventually the business becomes unviable and loans cannot be repaid. Given the depth and duration of the recent recessionary period, the number of business closures should have been very large. However, the total number appears to be relatively low – around 2% or 100,000 and the report suggests that the low interest rates have helped to ‘protect’ them.

Low interest rates have enabled businesses to meet their debt repayments more easily and with some banks being unwilling to admit to ‘bad loans’, businesses have benefited from loans being extended or ‘rolled over’. This has enabled them to survive for longer and as the report suggests, may be preventing a full recovery. The report’s author, Tom Papworth said:

Low interest rates and bank forbearance represent a vast and badly targeted attempt to avoid dealing with the recession. Rather than solving our current crisis, they risk dooming the UK to a decade of stagnation … We tend to see zombies as slow-moving and faintly laughable works of fiction. Economically, zombies are quite real and hugely damaging, and governments and entrepreneurs cannot simply walk away.

The problem they create is that resources are invested into these companies – labour, capital, innovation. This creates an opportunity cost – the resources may be more productive if invested into new companies, with greater productive potential. The criticism is that the competitiveness of the economy is being undermined by the continued presence of such companies and that this in turn is holding the UK economy back. Perhaps the interest rate rise that may happen this time next year may be what is needed to encourage the re-allocation of capital. However, a 0.5 percentage point rise in interest rates would hardly be the end of the world for some of these companies. Perhaps a more focused approach looking at restructuring is the key to their survival and the allocation of resources to their most productive use. The following articles and the report itself consider the case of the trading dead.

There has been an interesting debate recently about whether the austerity policies being pursued in the UK are the correct ones. What would have happened if the government had pursued a more expansionary policy? Would the increase in borrowing, at least in the short term, have triggered a financial crisis?

Without austerity policies, would the eurozone crisis have led to a collapse in investor confidence in the UK, especially if Greece had been forced out of the euro?

On the one side, Kenneth Rogoff argues that increasing the UK’s budget deficit would have been dangerous and could have led to a flight from the pound. Generally, but with some reservations, he supports the fiscal policies that have been pursued by the Coalition.

I am certainly not arguing that the UK or other advanced countries handled the post-crisis period perfectly. There should have been more infrastructure spending, even more aggressive monetary policy and probably more ruthless bank restructuring. But there has to be a balance between stimulus and stability. To assume we always knew things would calm down, and to retrospectively calibrate policy advice accordingly, is absurd

Paul Krugman and Simon Wren-Lewis challenge Rogoff’s arguments. Paul Krugman uses a version of the IS-LM model to analyse the effect of a loss of international confidence in the UK following problems in the eurozone and worries about excessive UK borrowing.

In the model, the LM curve (labelled MP in Krugman’s diagrams) illustrates the effect of an increase in real GDP on interest rates with a particular monetary policy (e.g. an inflation target or a Taylor rule, which involves a mix of two policy objectives: an inflation target and real GDP). As GDP rises, putting upward pressure on inflation, so the central bank will raise interest rates. Hence, like the traditional LM curve, the monetary-policy related LM curve will slope upwards, as shown in the diagram.

Initial equilibrium GDP is Y0. The rate of interest is at the minimum level, r0 (i.e. the rate of 0.5% that the Monetary Policy Committee has set since January 2009). This, in the model, is the liquidity trap, where any increase in money supply (a rightward shift in the LM curve) will have no effect on interest rates or GDP.

In Rogoff’s analysis of a crisis triggered by excessive borrowing and problems in the eurozone, the IS curve will shift to the left (as illustrated by curve IS1) as capital flows from the UK and confidence collapses. Real GDP will fall to Y1. This will be the outcome of fiscal expansion in the world of the early 2010s.

Krugman argues that the opposite will occur. The outflow of capital will drive down the exchange rate. This will lead to an increase in exports and a decrease in imports. Aggregate demand thus rises and the IS curve will shift to the right (e.g. to IS2 in the diagram. Real GDP will rise (e.g. to Y2 in the diagram). If the rise in aggregate demand is sufficient, the economy will rise out of the liquidity trap and interest rates will rise (e.g. to r2 in the diagram).

Not surprisingly, Rogoff challenges this analysis, as you will see if you read his second paper below. He doesn’t criticise the model per se, but challenges Krugman’s assumptions. For example, a depreciation of sterling by some 20% since 2008 doesn’t seem to have had a major effect in stimulating exports (see the chart in the news item, A balancing act). And exports could well have declined if the eurozone economy had collapsed, given that exports to the eurozone account for around 44% of total UK exports.

Rogoff’s assumptions in turn can be challenged. Simon Wren-Lewis argues that, provided a credible long-term plan for deficit reduction is in place, maintaining a fiscal stimulus in the short run, to keep the recovery going that was beginning to emerge in 2010, would help to increase investor confidence, not undermine it. And, with a policy of quantitative easing, which involves the Bank of England buying central government debt, there is no problem of a lack of demand for UK gilts by the private sector.

What is clear from this debate is the willingness of both sides to accept points made by the other. It is an extremely civilised debate. In fact, it could be seen as a model of how academic debate should be conducted. There is none of the ‘shouting’ that has charaterised much of the pro- and anti-austerity lobbying since the financial crisis burst onto the world stage.
