Inequality is growing in most countries. This can be illustrated by examining what has been happening to countries’ Gini coefficient. The Gini coefficient measures income inequality, where 0.00 represents perfect equality, with everyone in the country earning the same, and 1.00 represent perfect inequality, with one person earning all the country’s income. (Note that sometimes it is expressed as the ‘Gini index’, with 100 representing perfect inequality). In virtually all countries, the Gini coefficient has been rising. In the OECD countries it has risen by an average of 0.3% per annum over the past 25 years. The OECD average is now 0.31.

But despite the fact that the Gini coefficient has been rising, its value differs markedly from one country to another, as does its rate of change. For example, Finland’s Gini coefficient, at 0.26, is below the average, but it has been rising by 1.2% per annum. By contrast, Turkey’s Gini coefficient, at 0.41, is above the average and yet has been falling by 0.3% per annum.

The most unequal of the developed countries is the USA. According to OECD data, its Gini coefficient is 0.38, well above the values in the UK (0.34), Japan (0.33), Germany (0.30) France (0.29) and Denmark (0.26). What is more, inequality in the USA has been increasing by an average of 0.5% per annum since the mid 1980s.

According to the United Nations’ Human Development Report 2010, the USA’s Gini coefficient is even higher, at 0.41 (see Table 3 of the report). But this is still below that of Russia, with a figure of 0.44, a figure that has markedly worsened over time, along with those of other former Soviet countries. According to the report (page 72):

The worsening is especially marked in countries that were part of the former Soviet Union – which still have relatively low Gini coefficients because they started with low inequality. Transition has eroded employment guarantees and ended extensive state employment. Before the fall of the Berlin Wall, 9 of 10 people in socialist countries were employed by the state, compared with 2 of 10 in Organisation for Economic Co-operation and Development economies. While the privileged elite (the nomenklatura) often attained higher material well-being, the measured differences in income were narrow.

The Gini coefficient for Russia is the same as the average of the 39 developing countries with the lowest level of human development &nbash; and developing countries are generally much less equal than developed ones. Of course, some developing countries have an even higher Gini coefficient: for Angola the figure is 0.59; for Haiti it is 0.60.

The following three webcasts look at aspects of the growing inequality in Russia.

“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.

Anyone investing in commodities over the past few weeks will have been in for a bumpy ride. During the first part of 2011, commodity prices have soared (see A perfect storm brewing?). This has fuelled inflation and has caused the Bank of England to revise upwards its forecast for inflation (see Busy doing nothing see also Prospects for Inflation).

But then in the first week of May, commodity prices plumetted. On the 5 May, oil prices fell by 7.9% – their largest daily amount since January 2009. Between 28 April and 6 May silver prices fell from $48.35 per ounce to just over $33.60 per ounce – a fall of over 30%. And it was the same with many other commodities – metals, minerals, agricultural raw materials and foodstuffs.

Many financial institutions, companies and individuals speculate in commodities, hoping to make money buy buying at a low price and selling at a high price. When successful, speculators can make large percentage gains in a short period of time. But they can also lose by getting their predictions wrong. In uncertain times, speculation can be destabilising, exaggerating price rises and falls as speculators ‘jump on the bandwagon’, seeing price changes as signifying a trend. In more stable times, speculation can even out price changes as speculators buy when prices are temporarily low and sell when they are temporarily high.

Times are uncertain at present. Confidence fluctuates over the strength of the world recovery. On days of good economic news, demand for commodities rises as people believe that a growing world economy will drive up the demand for commodities and hence their prices. On days of bad economic news, the price of commodities can fall. The point is that when undertainty is great, commodity prices can fluctuates wildly.

Business leaders and politicians pay a great deal of attention to economic forecasts. And yet these forecasts often turn out to be quite wrong. Very few economists predicted the banking crisis of 2008 and the subsequent credit crunch and recession. And the recently released 2010 Q4 growth figures for the UK economy, which showed a decline in real GDP of 0.5%, took most people by surprise.

What is more, forecasters often disagree. If, for example, you look at the forecasts made by various panel members for Consensus Forecasts, you can see the divergence between their various predictions.

So why is economic forecasting so unreliable? Is it the fault of economic models? Or are there too many unpredictable factors that can impact on economies – factors such as business and consumer confidence, or political events, or natural disasters, such as the recent floods in Australia, South Africa and Brazil? Will economic forecasting always be a very inexact science?

Questions

  1. For what reasons may economic forecasts turn out to be wrong?.
  2. To what extent is economic forecasting like weather forecasting? Which is harder and why?
  3. Wo what extent can the poor accuracy of economic forecasts be blamed on the application of the ‘wrong type of economics’?
  4. How much variation is there in the independent forecasts of the UK economy reported by the Treasury (see HM Treasury link above)?
  5. Using the HM Treasury link, compare the forecasts made of 2010 in January 2010 with those made of 2010 in January 2011. Attempt an explanation of the differences.

GDP (or Gross Domestic Product) measures the value of output produced within a country over a 12-month period. It is this figure which we use to see how much the economy is growing (or shrinking). We can also look at how much different sectors contribute towards this figure. Over the past few decades, there has been a significant change in the output of different sectors, as a percentage of GDP, within the UK economy. In particular, the contribution of manufacturing has diminished, while services have grown rapidly.

However, there is one specific area that is making a growing contribution towards UK GDP and is expected to see acceleration in its growth rate by some 10% annually over the next few years: the internet. Although the internet is not an economic sector, the Boston Consulting Group (BCG) said that if it was, it would be the UK’s fifth largest sector and according to a report by Google, it is worth approximately £100 billion per year to the UK economy. Furthermore, it is an area in which the UK is one of the leading exporters. The emergence of the internet has transformed industries and individual businesses and the trend looks set to continue. The report by Google found that some 31 million adults bought goods and services online over the past year, spending some £50 billion.

What are the benefits for businesses of internet shopping and does it have an impact on the retail outlets on Britain’s highstreets? The answer is undoubtedly yes, but is it good or bad? What does the emergence of this new ‘sector’ mean for the UK economy?
