“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.

The debate about how much and how fast to cut the deficit has often been presented as a replaying of the debates of the 1920s and 30s between Keynes and the Treasury.
The justification for fiscal expansion to tackle the recession in 2008/9 was portrayed as classic Keynesianism. The problem was seen as a short-term one of a lack of spending. The solution was seen as one of expansionary fiscal and monetary policies. There was relatively little resistance to such stimulus packages at the time, although some warned against the inevitable growth in public-sector debt.
But now that the world economy is in recovery mode – albeit a highly faltering one in many countries – and given the huge overhang of government deficits and debts, what would Keynes advocate now? Here there is considerable disagreement.
Vince Cable, the UK Business Secretary, argues that Keynes would have supported the deficit reduction plans of the Coalition government. He would still have stressed the importance of aggregate demand, but would have argued that investor and consumer confidence, which are vital preconditions for maintaining private-sector demand, are best maintained by a credible plan to reduce the deficit. What is more, inflows of capital are again best encouraged by fiscal rectitude. As he argued in the New Statesman article below
One plausible explanation, from Olivier Blanchard of the IMF, is that the Keynesian model of fiscal policy works well enough in most conditions, but not when there is a fiscal crisis. In those circumstances, households and businesses react to increased deficits by saving more, because they expect spending cuts and tax increases in the future. At a time like this, fiscal multipliers decline and turn negative. Conversely, firm action to reduce deficits provides reassurance to spend and invest. Such arguments are sometimes described as “Ricardian equivalence” – that deficits cannot stimulate demand because of expected future tax increases.
Those on the other side are not arguing against a long-term reduction in government deficits, but rather that the speed and magnitude of cuts should depend on the state of the economy. Too much cutting and too fast would cause a reduction in aggregate demand and a consequent reduction in output. This would undermine confidence, not strengthen it. Critics of the Coalition government’s policy point to the fragile nature of the recovery and the historically low levels of consumer confidence
The following articles provide some of the more recent contributions to the debate.

According to a report just published by accountancy firm Deloitte, UK household real disposable incomes are set to fall for the fourth year in a row. What is to blame for this? According to Deloitte’s chief economic adviser, Roger Bootle, there are three main factors.
The first is the combination of tax rises and government expenditure cuts, which are now beginning to have a large impact. Part of this is the direct effect on consumer disposable incomes of higher taxes and reduced benefits. Part is the indirect effect on employment and wages of reduced public expenditure – both for public-sector employees and for those working for companies that supply the public sector.
The second is the rise in food, fuel and raw material prices, which have driven up the rate of inflation, thereby eroding real incomes. For most people, “pay growth is unlikely to catch up with inflation any time soon. Inflation is heading towards – and possibly above – 5%. Real earnings are therefore all but certain to fall for the fourth successive year in a row – the first time that this has occurred since the 1870s.”
The third is that demand in the private sector is unlikely to compensate for the fall in demand in the public sector. “I still doubt that the private sector can compensate for the cuts in public sector employment – which is already falling by 100,000 a year.
The upshot is that I expect households’ disposable incomes to fall by about 2% this year in real terms – equivalent to about £780 per household. And it will take until 2015 or so for incomes to get back to their 2009 peak.
… In terms of the year-on-year change in circumstances, although not the absolute level, that would make 2011 the worst year for households since 1977 (the depths of the recent recession aside). Were interest rates to rise too, conditions would arguably be the worst for households since 1952.”
Well, that’s a pretty gloomy forecast! The following articles examine the arguments and consider the likelihood of the forecasts coming true. They also look at the implications for monetary and fiscal policy.
Since I wrote the above, two more gloomy forecasts have been published: the first by the Institute for Fiscal Studies and the second by Ernst & Young’s Item Club. Both reports are linked to below.

The Greek economy is suffering. In April 2010, a €45 billion bailout package was agreed between Greece and the IMF and the EU. This was increased to €110 billion in May 2011. (The bailout loans expire in 2013.) In return for the loans, Greece agreed to tough austerity measures, involving tax increases, clamping down on tax evasion and government expenditure cuts. These measures have succeeded in cutting the deficit by 5 percentage points, but it still stood at 10.5% of GDP in 2010. Public-sector debt rose from 127% of GDP in 2009 to 143% in 2010. The market cost of borrowing on two-year government bonds currently stands at 23% per annum – a sign of a serious lack of confidence by investors in Greece’s ability to repay the loans.
The austerity measures have brought great hardship. Unemployment has soared. In February 2011, it reached 15.9%; in February last year it was 12.1%. According to the IMF’s World Economic Outlook (Table A2), Greek real GDP fell by 2.0% in 2009, by 4.5% in 2010 and is forecast to fall by 3.0% in 2011. But with GDP falling, this brings automatic fiscal stabilisers into play: lower incomes mean lower income tax revenues; lower expenditure means lower VAT revenue; higher unemployment means that more people claim unemployment-related benefits. This all makes it harder to meet the deficit reduction targets through discretionary tax rises and government expenditure cuts and makes it even more important to cut down on tax evasion. But, of course, the more taxes rise and the more government expenditure is cut, the more this suppresses aggregate demand. The austerity measures have thus worsened the recession.
On May 9, the ratings agency Standard & Poor’s downgraded Greece’s rating to B (15 points below the top rating of AAA and 6 points into ‘junk’ territory). It now has the lowest rating in Europe along with Belarus.
Worries have been growing that Greece might be forced to default on some its debt, or choose to do so. This would probably mean an extension of repayment periods. In other words, bondholders would be paid back in full but at a later date. This has been referred to as ‘debt re-profiling’. This could cause a renewed loss of confidence, not only in the Greek economy, but also in banks that are major lenders to Greece and which would be exposed in the case of default or restructuring.
The IMF and the ECB have been quick to stress that Greece can continue to manage its debt and that, if necessary, another loan might be negotiated. Anticipations are that Greece could indeed ask for a further bailout. But is this the answer? Or would it be better if Greece sought a restructuring of its debt? The following webcasts and podcasts consider the issue.

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.
