Category: Essentials of Economics: Ch 10

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%.

Questions

  1. What is aggregate demand? Which component is the biggest engine of growth for an economy?
  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!

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.

The government is sticking to its deficit reduction plan. But with worries about a lack of economic recovery, or even a double dip recession, some economists are calling for a Plan B. They back up their arguments by referring to the lack of consumer confidence, falling real incomes and rising commodity prices. Without a slowing down in cuts and tax rises, the lack of aggregate demand, they claim, will prevent a recovery.

The government maintains that sticking to the cuts and tax rises helps maintain international confidence and thereby helps to keep interest rates low. Also, it argues, if the economy does slow down, then automatic stabilisers will come into play. Finally, even though fiscal policy is tight, monetary policy is relatively loose, with historically low interest rates.

But will there be enough confidence to sustain a recovery? Economists are clearly divided. But at least the IMF seems to think so. In its latest assessment of the UK economy, although it has cut the growth forecast for 2011 from 2% to 1.5%, that is still a positive figure and thus represents a recovery, albeit a rather fragile one.

Questions

  1. Explain what is likely to happen to each of the components of aggregate demand.
  2. Is monetary policy loose enough? How could it be made looser, given that Bank rate is at the historically low level of 0.5% and could barely go any lower?
  3. What are automatic fiscal stablisers and how are they likely to affect aggregate demand if growth falters? What impact would this have on the public-sector deficit?
  4. What is meant by the ‘inventory cycle’? How did this impact on growth in 2010 and the first part of 2011?
  5. What is likely to happen to inflation in the coming months and why? How is this likely to impact on economic growth?
  6. Referring to the economists’ letter (the first link above), what do you think they mean by “a green new deal and a focus on targeted industrial policy” and how would this affect economic growth?

“There are ‘incredible economies of scale in cloud computing’ that make it a compelling alternative to traditional enterprise data centers.” According to the first article below, cloud computing represents a step change in the way businesses are likely to handle data or use software. Rather than having their own servers with their own programs, they use a centralised service or ‘public cloud’, provided by a company such as Microsoft, Google or Amazon Web Services. The cloud is accessed via the Internet or a dedicated network. It can thus be accessed not only from company premises but by mobile workers using tablets or other devices and thus makes telecommuting more cost effective.

There are considerable economies of scale in providing these computing services, with the minimum efficient scale considerably above the output of individual users. By accessing the cloud, individual users can benefit from the low average costs achieved by the cloud provider without having to invest in, and frequently update, the hardware and software themselves.

In the case of large companies, rather than using a public cloud, they can use a ‘private cloud’. This is hosted by the IT department in the company and achieves economies of scale at this level by removing the need for individual departments to purchase their own software and servers. Of course, the costs of providing the cloud is borne by the company itself and thus the benefits of lower up-front IT capital costs are reduced. This is clearly a less radical development and is really only an extension of the policy of many companies over the years of having centralised servers holding data and various software packages.

In autumn 2010, EMC Computer Systems commissioned economists at the Centre for Economics and Business Research (cebr) to quantify the full impact that cloud computing will have over the years ahead. According to the report, The Cloud Dividend:

The Cebr’s research calculates that €177.3 billion per year will be generated by 2015, if companies across Europe’s five largest economies continue to adopt cloud technology as expected.

The Cebr found that the annual economic benefit of cloud computing, by 2015, will be:
• France – €37.4 billion
• Germany – €49.6 billion
• Italy – €35.1 billion
• Spain – €25.2 billion
• UK – €30.0 billion

Will the ability of cloud computing to drive down the costs of IT mean that a new revolution is underway? Just how significant are the economies of scale and are they likely to grow as cloud providers themselves grow in size and experience? The following articles look at some of the issues.
