Category: Economics: Ch 17

Economic growth in developed countries, like the UK, exhibits two important characteristics. First, growth is positive over the long run such that the volume of output increases over time. Second, growth in the short-term is highly variable with patterns in the volume of output creating business cycles. With increased global interdependence through trade and integrated financial systems, domestic business cycles often resemble a global or international business cycle. This was certainly the case during the late 2000s. Recent releases from the Office for National Statistics provide an opportunity to look again at the characteristics of UK economic growth. In particular, they show the importance of differentiating between nominal and real values. Furthermore, revisions to the data have somewhat revised our view of economic growth before and after the economic crisis of the late 2000s.

The value of goods and services produced in the UK in 2010, as measured by GDP, is estimated at £1.46 trillion. This is the nominal GDP estimate because it measures the economy’s output for 2010 using the prices of 2010. Back in 1948, GDP measured at 1948 prices was £11.97 billion. Based on these nominal estimates the size of the UK economy would appear to have grown some 122 times which is the equivalent of growing by 8.1 per cent each year. However, some of this increase relates not to the volume of output but to the prices of the goods and services produced. It is for this reason that when analysing economic growth we ordinarily look at constant-price or real estimates of GDP. Such estimates effectively show what GDP would have been if prices had remained at the levels of a chosen year known as the base year. The base year now being used in the UK is 2008.

GDP at constant 2008 prices in 2010 is estimated at £1.40 trillion as compared with £314.5 billion in 1948. The real GDP figures reveal that the volume of UK output increased not by a factor of 122 but by a factor of 4.44; this is the equivalent to growth of 2.4 per cent each year.

The nominal GDP estimates for each year from 1948 up to 2010 rise with only one exception: 2009. In 2009, nominal GDP fell by 2.8 per cent. However, over the same period, real GDP fell during seven of the years. What this tells us, is that in six of the seven years, price increases were enough to offset falls in the volume of output such that nominal GDP increased. However, in 2009, the average price of the economy’s output, which is measured by the GDP deflator, rose by a just a little under 1.7 per cent, while the volume of output and, hence, real GDP, fell by almost 4.4 per cent.

The real annual GDP numbers estimate that the volume of UK output declined both in 2008 and 2009. In 2008 output is thought to have fallen by 1.1 per cent, while in 2009, as we have just seen, it fell by 4.4 per cent. The last time the UK experienced two consecutive annual (yearly) falls in output was in 1980 and 1981 when output fell by 2.1 per cent and 1.3 per cent respectively.

If we want to identify recessions then yearly GDP numbers will not do, rather, we need to use quarterly GDP numbers. This is because we are looking for two consecutive quarters where real GDP (output) declined. The revised GDP data show that the UK experienced five consecutive quarterly falls in real GDP in the late 2000s. We went into recession in Q2 of 2008 and came out in Q3 of 2009. As a result, real GDP was 7 per cent lower than before the UK economy entered recession. The previous recession, from Q3 of 1990 to Q3 of 1991 (5 quarters), saw UK output fall by 2.5 per cent. Between these two recessions the UK experienced 66 consecutive quarters of economic growth during which time the revised estimates show that the average annual rate of growth was 3 per cent. Compared with the recession of 2008/09, the next deepest recession in recent times occurred between Q1 of 1980 and Q1 of 1981 (5 quarters) when output fell by 4.7 per cent. In other words, these figures help to illustrate the extraordinary depth of the 2008/9 recession.

Stock markets have been plummeting. The FTSE 100 index was 6055 on 7 July 2011; by 10 August, it was 17% lower at 5007. Since then it has risen as high as 5418, but by 13 September was down to 5092. Other stock markets have fared worse. The French index fell 30% between early July and September 13, and the German DAX index fell 32% over the same period.

These falls in share prices reflect demand and supply. Investors are worried about the future of the eurozone and the health of the European economy as Greek default looks more and more likely and as the debts of various other European countries, such as Portugal, Ireland and Spain, seem increasingly unsustainable in an environment of sluggish economic growth. They are also worried about high public-sector debt in the USA and the likelihood that global recovery will peter out.

The ‘bear’ market (falling share prices) reflects increased selling of shares and a lack of demand. Not only are investors worried about the global economy, they are also speculating that share prices will fall further, thereby compounding the falls (at least until the ‘bottom’ is reached).

But why have share prices fallen quite so much? And does it matter to the general public that this is happening? The following articles seek to answer these questions.

The growing interdependence of economies has never been more true than over the past few years. The credit crunch began in the US and gradually spread to the rest of the world. As the saying goes, ‘when America sneezes, the world catches a cold’. The US economy is the largest in the world and with such a close relationship to the UK, its economic situation is critical. GDP growth in the first quarter was a mere 0.4% and in the second quarter, it was revised down from the US Commerce Department’s original estimate of 1.3% to just 1%. This was attributed to weaker growth in business inventories, a fall in exports and less spending from the state and local governments. Personal consumption expenditure and exports did rise, but the increase in the former was hardly noticeable (0.4%) and in both cases, the second quarter increase was significantly down on that in the first quarter.

With GDP growth remaining low, there’s not much better news when it comes to US unemployment, which remained at 9.1% from July. It was expected that a further 70,000 jobs would be created in August, but the latest figures suggest that no new jobs were created. It seems that the data on growth and the components of aggregate demand are enough to bring consumer and investor confidence down. Virginie Maisonneuve said:

‘Companies that are overall doing OK are hesitating to hire and invest further, creating some fragility for the economy… We will need some help from the Fed and the government to avoid a recession.’

President Obama is due to make a speech in which he will outline a new plan to boost economic growth. Crucial to this will be restoring confidence, as without it, businesses will not invest, consumers will save rather than spend, jobs will not be created and growth will remain sluggish. This will do nothing to help the still weak economies of Europe. Indeed, following news of the US job situation, stock markets across the world fell, as fears of recession set in. The Dow Jones opened 2% down, the FTSE 100 ended 2.3% down (although this was also affected by a weakening in the construction sector), markets in Germany, France and Spain were down by over 3% and in Italy by over 4%.

  2. Why did markets decline following the data on US jobs?
  3. Why is the economic situation in America so important to the economic recovery of other countries across Europe?
  4. Why are there suggestions that the US is underestimating its inflation?
  5. Why is the US economic data for the second quarter of 2011 so much worse than that of the first quarter? What could have caused this downturn?
  6. What action could the government and the Fed take to boost confidence in the US economy and stimulate economic growth? Can any of this be done without causing inflation?

I found myself singing this morning which I have to admit is not the most pleasant experience for those in ear-shot. I was singing to the tune of ‘love is all around us’. But rather than the words of the song performed by the Troggs in the late 1960s and by Wet Wet Wet in the 1990s, I found myself singing ‘debt is all around us’. It could easily have been the sub-conscious effect of the headlines relating to government debt (also known as national debt). But, actually it was the effect of having looked at my latest credit card statement and noting the impact that my summer holiday had had on my financial position! Relaxation, so it seems, doesn’t come cheap. With this in mind, I have just taken a look at the latest bank of England figures on British household debt. You can do the same by going to the Bank of England’s statistical release lending to individuals.

The latest figures reveal that at the end of June 2011 households in Britain had a stock of debt of £1.451 trillion. Now this is a big number – not far short of the economy’s annual Gross Domestic Product. But, interestingly, this is its lowest level in three years. Indeed, over the past twelve months the stock of household debt has fallen by £6 billion. This is the result of the sector’s repayment of unsecured debt, such as credit card debt and overdrafts. The stock of unsecured debt has fallen by £8.2 billion or 3.8% over the past year to stand at £209.7 billion.

The remaining £1.241 trillion of household debt is secured debt which is debt secured against property. The stock of secured debt has risen by £2.16 billion over the last 12 months, but this equates to a rise of less than 0.2%. In fact, further evidence from the Bank of England reveals that households are not only looking to reduce their exposure to unsecured debt but to pay off mortgage debt too. You might wonder how this might be occurring given that the stock of mortgage debt has risen, albeit only slightly. The answer lies in the growth of housing investment relative to that of mortgage debt. Housing investment relates, in the main, to the purchase of brand new homes and to major home improvements. As our population grows and the housing stock expands and as we spend money on improving our existing housing stock we acquire more mortgage debt. Bank of England figures show that housing investment has been greater than new secured lending. Consequently, the additions to the stock of lending have been less than housing investment. This gives rise to negative housing equity withdrawal, i.e. negative HEW.

The Bank of England estimates that in Q1 of 2011 there was an increase in housing equity of £5.8 billion. Negative housing equity withdrawal (HEW), an injection of housing equity, has occurred every quarter since Q2 2008. Since then, the UK household sector has injected some £63.7 billion of housing equity. The opportunity cost of this injection is that by increasing equity in property households are using money that could have been used for consumption or for purchasing financial assets. The extent of this negative HEW over the past 12 quarters has been the equivalent to 2.2% of disposable income.

While my credit card may have ballooned this month, it would appear that the household sector is looking to reduce its debt exposure. I will be looking to do likewise!

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?
