“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.

While inflation is a concern in the UK and is making the Bank of England think twice about keeping interest rates at their all time low of 0.5%, inflation in Japan is being celebrated. The Japanese economy has been plagued by deflation for over a decade and for the past 2 years inflation has never been above 0%. However, in April the consumer price index (CPI) rose to 0.6% from the previous year, fuelled by petrol prices. Strangely it might be the Japanese earthquake and tsunami that helped this situation, as Japan was unable to generate sufficient electricity and hence had to import fuel from abroad.

A typical question from non-economists is always about why deflation and hence falling prices is such a bad thing. Surely, it’s great for consumers? For those shopping for bargains, perhaps it is helpful – after all, if prices fall, a consumer’s real income will be higher. However, the problem with falling prices is that people start to hold off buying. If you want to buy a car, but expect prices to be lower next month, then it’s a rational decision to delay your purchase until next month when prices are lower. However, next month, you still expect prices to be lower in the following month and so delay purchasing again. And so the process continues. When people expect prices to fall they put off their purchases, this reduces demand and so prices do indeed fall. There are also costs for businesses: as consumers delay buying, sales begin to fall. And businesses are also consumers, and so they start delaying their purchases of inputs.

While many central banks across the world have begun to tighten monetary policy, the Japanese central bank seems inclined to keep monetary policy loose and has even considered expanding the emergency lending programme. As Azusa Kato, an economist at BNP Paribas, said:

“The bank will probably add stimulus if it sees more signs of weakening demand”. “If you strip out energy and food costs, consumer prices are basically flat now.”

Despite this inflationary pressure, many believe that it is unlikely to continue and deflationary pressures may appear once again in the near future. The following articles consider the Japanese deflationary situation.

The banking sector was at the heart of the credit crunch and it may also be at the heart of the recovery. Too much lending to those who could not repay has now translated into government encouragement and targets to stimulate further lending. Banks made a deal with the government (Project Merlin) to lend £76bn to small and medium sized companies (SMEs) in 2011, however, the data for the first quarter of 2011 shows that the top five UK banks lent only £16.8bn, some £2.2bn short of their quarterly target (about 12%). Despite this sum still being a significant figure, small companies have said that they are still finding it difficult to obtain credit from banks. A poll found 44% of companies that asked for a loan were turned down and many were discouraged from even applying as they had almost no chance.

Encouraging banks to lend and hence stimulating investment by businesses may prove crucial to the UK’s recovery. Vince Cable’s words with regard to lending emphasise its importance:

“We will monitor the banks’ performance extremely closely and if they fail to meet the commitments they have agreed we will examine options for further action.”

If small businesses can obtain credit, it will help them to develop and expand and this should have knock on effects on the rest of the economy. Jobs could be created, giving more people an income, which in turn should stimulate consumption, further investment and finally aggregate demand. It may not be the case that the UK’s recovery is entirely dependent on bank lending, but it could certainly play an important role, hence the government’s insistence for further lending. It may also act to create confidence in the economy. The following articles consider the bank’s role in providing credit to SMEs.

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

Each month the Bank of England releases figures on the amount of net lending to households. Net lending measures the additional amount of debt acquired by households in the month and so takes into account the amount of debt that households repay over the month. For some time now, the levels of net lending have been remarkably low. Over the first quarter of 2011, monthly net lending to households averaged £1.2 billion. This might sound like a lot of money and in many ways this is true. But, to put the weakness of this figure into perspective, the monthly average over the past ten years is £7 billion.

Household debt can be categorised as either secured debt or unsecured debt. The former is mortgage debt while the latter includes outstanding amounts due on credit and store cards, overdrafts and personal loans. Levels of net secured lending have averaged £1 billion per month over the first 3 months of 2011. This compares with a 10-year average of £5.8 billion per month. Levels of net unsecured lending have averaged £196 million per month over the first 3 months of 2011. This compares with a 10-year average of £1.2 billion per month. In 12 of the months between December 2008 and January 2011 net unsecured lending was actually negative. This means that the value of repayments was greater than new unsecured lending. Once bad debts are taken into account we observe from the autumn of 2008 almost persistent monthly falls in the stock of unsecured debt.

Weak levels of net lending reflect two significant factors. First, on the supply-side, lending levels remain constrained and credit criteria tight. Second, on the demand-side, households remain anxious during these incredibly uncertain times and would appear to have a very limited appetite for taking on additional credit.

Finally, a note on the stock of debt that we households collectively hold. The stock of household debt at the end of March 2011 was £1.45 trillion. This is £7.2 billion or 0.5% lower than in March 2010. The stock of secured debt has risen over this period by only £2.6 billion or 0.2%, while unsecured debt – also known as consumer credit – has fallen £9.9 billion or 4.5%. These figures help to reinforce the message that British households continue to consolidate their financial positions.
