“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.

As the new tax year begins, many changes are taking place. In order to cut the large budget deficit, sacrifices have to be made by all. The tax and benefit changes could make households worse off by some £2bn this year – definitely not good news for those households already feeling the squeeze. However, the Coalition say that the poorest households will be made better off relative to the rich.
Personal allowance is increasing by £1,000, which is expected to benefit £800,000 people who will no longer pay any tax. At the same time, the 40% tax bracket is being reduced from £43,875 to £42,475, which will bring another 750,000 people into this higher tax bracket, bringing in much needed revenue for the government. Employee’s national insurance contributions will rise by 1% and according to Credit Action, this will leave households £200 worse off per year. Benefits do rise with inflation, but they are to be indexed against the CPI rather than the RPI. The RPI is usually higher and hence benefits will not increase by as much, again leaving some people worse off. Child benefit will be frozen for all and will then be removed for higher rate tax payers from 2013. According to the Treasury, it is the top 10% of households who will lose the most from these needed changes. However, as Justine Greening, the Economic Secretary to the Treasury said:
‘Labour left behind a complete mess with no plan to deal with it, apart from to run up more debts for the next generation to pay off.’
In order to cut the deficit, which stands at an estimated £146bn, spending must fall and tax revenue for the government must rise. The government argues that if cuts are not made today, even higher cuts will be necessary in the future and this will harm the poorest even more. Whilst the Treasury have accepted that there was a ‘marginal loss’ across the population, it is the highest earning households that will suffer the most.

The Chancellor of the Exchequer, George Osborne, delivered the annual Budget on 23 March. He was very keen to have a ‘Budget for growth’ given the pessimism of consumers (see Table 1, UK, line 3, in Business and Consumer Survey Results, February 2011) and the bad news on inflation (see 4.4% and rising?).
But what could he do? Despite being urged by the Labour opposition to stimulate aggregate demand by cutting the deficit more slowly, he ruled out this alternative. It would be perceived by markets, he argued, as a sign that he was ‘gong soft’ on the commitment to tackle the deficit.
If stimulating aggregate demand directly was out, the alternative was to use supply-side policy: to provide more favourable conditions for business by cutting ‘red tape’, providing tax incentives for investment, reducing regulations, simplifying tax, cutting corporation tax financed by tax increases elsewhere, creating 21 ‘enterprise zones’ and funding extra apprenticeships and work experience placements.
The links below give details of the measures and consider their likely effectiveness. Crucially, the Budget will be much more successful in encouraging investment if people think it will be successful. In other words, its success depends on how it affects people’s expectations. Will it help confidence to return – or will the impending tax increases and cuts on government expenditure only make people more pessimistic?

One of the interesting things about the recent recession was the dilemma that it posed for governments. As aggregate demand fell, unemployment rose, incomes fell, which reduced demand further and so national output began to decline. Obviously there were many other factors contributing to this decline, in particular the housing market, but the long and the short of it is, aggregate demand was falling. With the AD curve shifting inwards, we would expect the average price level to fall at the same time: i.e. inflation doesn’t tend to be much of a problem during a recession. It is this fact that posed something of a dilemma. In the recession, not only was aggregate demand low, but inflation was rising. The explanation for this: in large part due to rising commodity prices – a supply-side shock. Governments had to deal with low national output and inflation: this combination made policy changes much more complex.
While prices for many goods and commodities did fall significantly after their peak in 2008, there has been a gradual rise again and there seems to be no end in sight. Headline food prices, in particular, have increased almost to their 2008 levels, although in real terms prices are still lower. Onions in India; cabbage, pork and mackerel in South Korea; chillies in Indonesia – the list goes on. The rapidly rising prices of these basic foodstuffs has, in many cases, led to emergency government intervention. However, there are fewer concerns this time round, as many hope that the causes of these higher prices are not just the increases in demand but crucially temporary supply shocks. Bloomberg’s Businessweek Assistant Managing Editor, Sheelah Kolhatkar, said:
There are a lot of reasons [for rising prices]. Weather is cited as a big one. There’s been sort of freak weather in different parts of the world. Russia experienced a drought. There are floods in Australia. There’s been sort of freezing weather in Florida. Our own Midwest experienced flooding earlier this year. And because the market for a lot of these food commodities is global, when something strange happens somewhere, that can affect a crop.
On the other hand, there are growing concerns at the timing of this inflation: the developed world has barely escaped from recession. How is it that inflation can already be a problem? Furthermore, with loose monetary policy in many countries, rising food and commodity prices could continue for some time.
An interesting question to consider is which countries will be affected the most? In Britain, like other developed countries, food consumption accounts for between 15 and 20 per cent of a household budget. However, in developing countries, food can take up between 50 and 75 per cent of a houshold budget, so any rise in food prices is disastrous.
What does it mean for the recovery? Well, if food (a necessity) is increasing in price, households have little choice but to pay the higher prices. This means they have less disposable income for other goods, hence aggregate demand may be adversely affected. The following articles will hopefully give you some ‘food for thought’!

According to GDP figures released on 15 August, China overtook Japan in the second quarter of 2010 to become the world’s second largest economy. This raises two questions: just what do the GDP figures mean and why has this happened?
The GDP figures are total figures measured in US dollars at current exchange rates. According to these nominal figures, Japan’s GDP was $1.286 trillion in the second quarter of 2010; China’s was $1.335 trillion. This follows several years when Chinese growth rates have massively exceeded Japanese ones.
As far as explanations are concerned, economists look to a number of different factors, including investment policies, relative exchange rates, confidence, deflation in Japan and the scope for catching up in China.
The following podcasts and webcasts look at these questions, as do the articles.
