Friday 5 August 2011 saw the end of a very bad fortnight for stock markets around the world. In Japan the Nikkei 225 had fallen by 8.2%, in the USA the Dow Jones had fallen by 9.8%, in the UK the FTSE 100 was down 11.6% and in Germany the Dax was down 14.9%. In the first five days of August alone, £148 billion had been wiped off the value of the shares of the FTSE 100 companies and $2.5 trillion off the value of shares worldwide.

But why had this happened and what are likely to be the consequences?

The falls have been caused by the growing concerns of investors about the health of the global economy and the global financial system. There are worries that the European leaders at their summit on 21 July did not do enough to prevent the default of large countries such as Spain and Italy. There are concerns that the US political system, following the squabbling in Congress over raising the sovereign debt ceiling for the country, may not be up to dealing with the country’s huge debts. Indeed, the rating agency, Standard & Poor’s, downgraded the USA’s credit rating from AAA to AA+. This is the first time that the USA has not had top rating.

Then there are worries about the general slowing down of the world economy and how this will compound the problem of sovereign debt as it hits tax revenues and makes it harder to reduce social security payments. Underlying all this is the fear that the problem of indebtedness that contributed to the banking crisis of 2007/8 has not gone away; it has simply been transferred from banks to governments. As Robert Peston states in his article, linked to below:

The overall volume of indebtedness in the economy is therefore still with us – although it has been shuffled from financial sector to public sector.

And if you took the view four years ago that the quantum of debt in the system was unsustainably large, then you would argue that by propping up the banks, the day of reckoning was being postponed, not cancelled.

… just like the awakening in 2007 to the idea that many of the housing loans and associated financial products were worthless, so there is a growing fear that a number of financially overstretched governments, especially in the eurozone, will not be able to repay their debts in full.

Which brings us to the consequences. Key to the answer is confidence. If governments can reassure markets over the coming days and weeks that they have credible policies to support highly indebted countries in the short term and to sustain demand in the global economy (e.g. through further quantitative easing in the USA (QE3)); and if they can also reassure markets that they have tough and credible policies to reduce their debts over the longer term, then confidence may return. But it will not be an easy task to get the balance right between sustaining recovery in the short term and fiscal retrenchment over the long term. Meanwhile consumers are likely to become even more cautious about spending – hardly the recipe for recovery.

The quarter 2 UK GDP growth figures were published at the end of July. They show that real GDP grew by a mere 0.2% over the quarter, or 0.7% over 12 months. These low growth figures follow 2010Q4 and 2011Q1 growth rates of –0.5 and 0.5 respectively, giving an approximately zero growth over those six months. The recovery that seemed to be gathering pace in early 2010, now seems to have petered out, or at best slowed right down. According to an average of 27 forecasts, collated by the Treasury, GDP is expected to grow by just 1.3% in 2011 – below the potential rate of economic growth and thus resulting in a widening of the output gap.

With such a slow pace of recovery, current forecasts suggest that it will be 2013 before the economy returns to the pre-recession level of output: just over five years after the start of the recession in 2008. This chart from the National Institute of Economic and Social Research compares the current recession with previous ones and shows how the recovery is likely to be the slowest of the five recessions since the 1930s.

The Confederation of British Industry (CBI) in its latest Economic Forecast says that the economic outlook has become more challenging.

The intensification of euro area sovereign debt pressures has added to the downside risks facing the UK economy – although the agreement reached at the recent summit appears to represent an initial step towards resolving the issues.

Meanwhile the global economy is going through a soft patch, partly as a result of the previous surge in commodity prices, which has put pressure on household budgets and raised costs for businesses.

Against this backdrop confidence appears to have wilted somewhat.

The opposition blames the slow pace of recovery on the austerity measures imposed by the government. The depressing of aggregate demand by cutting government expenditure and raising taxes has depressed output growth. The problem has been compounded by a lack of consumer spending as real household incomes have been squeezed by inflation and as consumers fear impending tax rises and cuts in benefits. And export growth, which was hoped to lead the country’s recovery, has been hit by weak demand in Europe and elsewhere.

With weak growth, the danger is that automatic fiscal stabilisers (i.e. more people claiming benefits and lack of growth in tax revenues) will mean that the government deficit is not cut. This may then force the Chancellor into further austerity, which would compound the problem of low demand. The opposition has thus been calling for a (temporary) cut in VAT to stimulate the economy.

The government argues that rebalancing the budget is absolutely crucial to maintaining international confidence and Britain’s AAA rating by the credit rating agencies, Moody’s, Fitch and Standard and Poor’s (S&P). Any sign that the government is slacking in its resolve, could undermine this confidence. According to George Osborne, while other countries (including the USA and many eurozone countries) are facing a lot of instability, “Britain is a safe haven. We have convinced the world that we can deal with our debts, bring our deficit down, and that’s meant that interest rates, for British families, for British businesses, are lower than they would otherwise be; it means that our country’s credit rating has been affirmed … and it means that we have that crucial ingredient of any recovery – economic stability.”

What is more, the government claims that the essence of the UK’s problem of low growth lies on the supply side. The focus of growth policy, it maintains, should be on cutting red tape, improving efficiency and, ultimately, in reducing taxes.

What we are witnessing is a debate that echoes the Keynesian/new classical debates of the 1980s and earlier: a debate between those who blame the current problem on lack of aggregate demand and those who blame it on supply-side weaknesses, including weaknesses of the banking sector.

So what should be done? Is it time for a (modest) fiscal expansion, or at least a reining in of the fiscal tightening? Should the Bank of England embark on another round of quantitative easing (QE2)? Or does the solution lie on the supply side? Or should policy combine elements of both?

With a mounting crisis in the eurozone, heads of government met in an emergency meeting in Brussels on 21 July.

The task was a massive one: how to tackle Greece’s growing debt crisis and stave off default; how to protect other highly indebted countries which have already had to seek emergency bailouts, namely Ireland and Portugal, from falling market confidence and thus rising interest rates, thereby making their debts harder to service; how to prevent speculative pressures extending like a contagion to other highly indebted countries, such as Spain and Italy; how to prevent speculation against the euro and even to prevent its break-up; how to reduce the size of budget deficits at a time of low growth without jeopardising that growth. A problem is that Greece has already adopted the required austerity measures for it to receive a second bailout from the EU agreed at the end of June, and yet its debt burden is likely to rise as growth remains negative.

Eurozone leaders recognised that the stakes were high. Failure could see contagion spread, interest rates soar and perhaps one or more countries leaving the euro. No agreement was not an option. As it turned out, the agreement was more comprehensive than most commentators had expected. Markets reacted positively. Stock markets in Europe and around the world rose and the euro strengthened.

So what was the agreement? Has it solved the Greek and eurozone crises? Will it prevent contagion? Or has it merely put the problem on hold for the time being? Will more fundamental measures have to be put in place, such as much fuller fiscal union, if the eurozone is to function as an effective single currency area? The following is a selection of the hundreds of articles worldwide that have reported on the summit and the agreement.

In 2009, Nudge: Improving Decisions about Health, Wealth, and Happiness was published. This book by Richard Thaler and Cass R. Sunstein examines how people are influenced to make decisions or change behaviour.

According to Thaler and Sunstein, people can be ‘nudged’ to change their behaviour. For example, healthy food can be placed in a prominent position in a supermarket or healthy snacks at the checkout. Often it is the junk foods that are displayed prominently and unhealthy, but tasty, snacks are found by the checkout. If fashion houses ceased to use ultra thin models, it could reduce the incentive for many girls to under-eat. If kids at school are given stars or smiley faces for turning off lights or picking up litter, they might be more inclined to do so.

The UK government has been investigating the use of ‘nudges’ as a way of changing behaviour, and the House of Lords Science and Technology Committee has been considering the question. It has just published its report, Behaviour Change. The summary of the report states that:

The currently influential book Nudge by Richard Thaler and Cass Sunstein advocates a range of non-regulatory interventions that seek to influence behaviour by altering the context or environment in which people choose, and seek to influence behaviour in ways which people often do not notice. This approach differs from more traditional government attempts to change behaviour, which have either used regulatory interventions or relied on overt persuasion.

The current Government have taken a considerable interest in the use of “nudge interventions”. Consequently, one aim of this inquiry was to assess the evidence-base for the effectiveness of “nudges”. However, we also examined evidence for the effectiveness of other types of policy intervention, regulatory and non-regulatory, and asked whether the Government make good use of the full range of available evidence when seeking to change behaviour.

The report finds that nudges

… used in isolation will often not be effective in changing the behaviour of the population. Instead, a whole range of measures – including some regulatory measures – will be needed to change behaviour in a way that will make a real difference to society’s biggest problems.

So is there, nevertheless, a role for nudges in changing behaviour – albeit alongside other measures? Read the report and the articles below to find out!

Just how large is the UK economy and how rapidly is it growing? These were questions we asked, back at the turn of the year, in Getting real with GDP when reviewing economic data for the third quarter of 2010. We update this blog in light of the latest Quarterly National Accounts release from the Office for National Statistics.

The latest Quarterly National Accounts release estimates the value of our economy’s output during Q1 of 2011 at £375.3 million. When measured across the latest four quarters, i.e. from the start of Q2 2010 to the end of Q1 2011, the total value of our economy’s output was £1.472 trillion. Across calendar year 2010 the UK’s GDP is estimated to have been £1.455 trillion.

When analysed in terms of the total expenditure on the goods and services produced in the latest four quarters, household final consumption contributed £931 billion of Gross Domestic Product. In other words, household expenditure over these four quarters was equivalent to 63% of GDP, almost exactly in line with its average since 1948. This demonstrates the importance of spending by households for short-term economic growth. Households help to shape the business cycle.

Another important expenditure-component of GDP is gross capital formation. This is capital expenditure by the private and public sector and is estimated to have been £219.6 billion over the latest four quarters, equivalent to 15% of GDP. As well as affecting current levels of GDP, gross capital formation also affects our economy’s potential output. In other words, changes in capital expenditure can impact both on the demand-side and the supply-side of the economy. Interestingly, the long-term average share for gross capital formation in GDP is around 18% and so about 3 percentage points higher than is currently the case.

So far we have looked at the level of economic activity measured at current prices. But, what about the rate at which the economy is growing? When analysing the rate of economic growth economists look at GDP at constant prices. By doing this economists can infer whether the volume of output has increased. This is important because in the presence of price rises, an increase in the value of output could occur even if the volume of output remained unchanged or actually fell. For instance, in 1974 the volume of output or real GDP fell by 1.3%, but because the average price of our domestic output – the GDP deflator – rose by 14.9%, GDP measured at current prices rose by nearly 13.4%.

The latest ONS figures show that in the first quarter of 2011 real GDP grew by 0.5% (nominal GDP grew by 1.7%). This follows a 0.5% fall in real GDP the final quarter of 2010 (nominal GDP grew by 1.2%). Compared with Q1 2010, the volume of output of the UK economy in Q1 2011 is estimated to have grown by 1.6%.

Exports were the fastest growing component of aggregate demand in Q1, rising in real terms by 2.4%, while import volumes decreased by 2.4%. Export volumes in Q1 were 9.3% higher than a year earlier. In contrast, capital expenditures contracted sharply in the first quarter, falling by 4.2%. This follows on the back of a 0.6% fall in the final quarter of last year. This has reversed much of the strong capital expenditure growth seen during the earlier part of 2010.

We finish by looking at the growth in household spending. In the first quarter of the year real household spending fell by 0.6%. This follows a 0.2 fall in Q4 2010 and zero growth in Q3 2010. This helps to explain some of the difficulties that particular retailers have faced of late. Some context to these disappointing consumption numbers is provided by patterns in household sector disposable income. The sector’s disposable income fell by 0.8% in Q1 2011 which follows on from a 0.9% fall in the last quarter of last year. The result of this is that the household sector’s real disposable income in Q1 2011 was 2.7% lower than in Q1 2010. This was the fastest annual rate of decline since the third quarter of 1977.

Questions

  1. What do you understand by the terms nominal GDP and real GDP?
  2. Can you think of any other contexts in which we might wish to distinguish between nominal and real changes?
  3. The following are the estimates of GDP at constant 2006 prices:
    Q1 2011= £330.724bn, Q4 2010= £329.189bn, Q1 2010= £325.360bn
    Calculate both the quarterly rate of change and the annual rate of change for Q1 2011.
  4. What would happen to our estimates of the level of constant–price GDP in (3) if the base year for prices was 1996 rather than 2006? What if the base year was 2011? What would happen to the quarterly and annual growth rates you calculated in each case? Explain your answer.
  5. Explain how gross capital formation could have both demand-side and supply-side effects on the economy. How significant do you think such supply-side effects can be?
  6. How important for short-term economic growth do you think household spending is? What factors do you think will be important in affecting household spending in the months ahead?
  7. What factors do you think help to explain the 2.7% annual rate of decline reported in Q1 2011 in the household sector’s real disposable income?
  8. The real annual rate of decline in household spending reported in Q1 2011 was 0.5%. Would you have expected this percentage decline to have been the same as for real disposable income? Explain your answer.
