The National Minimum Wage is a rate applied to most workers in the UK and is their minimum hourly entitlement. For adults over the age of 21, it has recently been increased to £6.08 – 15p rise. Rises have also been seen for 18-20 year olds, 16 and 17 year olds and apprentices. Undoubtedly this is good news for workers receiving the minimum wage, but what does it mean for firms and national unemployment data?

Market wages are determined by the interaction of the demand and supply of labour and when they are in equilibrium, the only unemployment in the economy will be equilibrium unemployment, namely frictional or structural. However, when the wage rate is forced above the equilibrium wage rate, disequilibrium unemployment may develop. At a wage above the equilibrium the supply of labour will exceed the demand for labour and the excess is unemployment. Furthermore, firms are already facing difficult times with the economic climate: sales remain relatively low, but costs are still high. By increasing the national minimum wage, firms will face higher labour costs and this may discourage them from taking on new workers, but may also force them into laying off existing workers.

It is hoped that the size of the increases will help low paid workers, as costs of living continue to rise, but won’t cause firms to reduce their labour force. This is one reason, in particular, why the increase in the minimum wage for young workers is smaller than that for adults. Youth unemployment is relatively high and so it is essential that firms keep these workers on, despite their increased costs.

Although the TUC has welcomed the increases in the National Minimum Wage, saying they will benefit some 900,000 workers, the General Secretary of Unison has said that it isn’t high enough.

“The rise to £6.08 is a welcome cushion, but with the price of everyday essentials such as food, gas and electricity going up massively, it won’t lift enough working people out of the poverty trap.”

“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 snow the UK has seen over the past two winters created massive disruption, but that is only one reason for hoping for a milder winter to come. With the cold weather, the UK economy faced threats of gas shortages, as households turned on their heating. However, despite the freezing temperatures, many households were forced to turn off their heating regularly, due to the excessive bills they would face. This trend is expected to be even more prevalent if the 2011/12 winter is as cold, as fuel tariffs are predicted to rise. The Bank of England has said that gas and electricity prices could rise this year by 15% and 10% respectively. British Gas’s Parent company, Centrica said:

“In the UK the forward wholesale prices of gas and power for delivery in winter 2011/12 are currently around 25% higher than prices last winter, with end-user prices yet to reflect this higher wholesale market price environment.”

These predictions might see the average UK household paying an extra £148 over the next year. Although these are only estimates, we are still very likely to see many households being forced to turn off their heating. One thing which therefore is certain: a warmer winter would be much appreciated!

Are we heading for ‘perfect storm’ in commodity production and prices? Certainly the prices of many commodities have soared in recent months. These include the prices of foodstuffs such as dairy products, cooking oils and cereals, crude oil, cotton, metals and many other raw materials. The overall world commodity price index has risen by 28% in the past 12 months. The following are some examples of specific commodities:

Price rises in the 12 months to February 2011

• Wheat 62%
• Maize 59%
• Coffee 70%
• Beef 39%
• Sugar 46%
• Palm kernal oil 142%
• Soybean oil 50%
• All food price index 32%
• Crude oil 20%
• Cotton 132%
• Fine wool 55%
• Softwood timber 25%
• Iron ore 78%
• Copper 29%
• Tin 55%
• All metals index 58%
• Rubber 79%.

The problems are both short term and long term, and on both the demand and supply sides; and the effects will be at micro, macro and global levels. Some hard choices lie ahead.

The following webcast, articles and reports explore both the current position and look into the future to ask whether rising commodity prices are likely to continue or even accelerate.

The first link is to a BBC World Debate which considers the following issues: “Is scarcity of natural resources a serious challenge for developing and advanced economies? How great is the risk that scarcity might lead to conflict, both within and between nations? Might a scramble for resources lead to a retreat from globalisation and to greater protectionism?”

Growth in the UK for the final quarter of 2010 was originally at -0.5%. However, the latest data has revised that figure to -0.6% and not all of this was down to the snow. Analysts say that the snow effect is still believed to explain the 0.5% contraction, but the economy therefore declined by 0.1% because of other reasons and retailers have seen the effects. Primark has reported a ‘noticeable’ slowdown in demand since the beginning of 2011. With increasing VAT and rising cotton prices, clothing retailers are feeling the squeeze. The same is true of UK consumers. With an increase in VAT and high inflation, consumers’ purchasing power has simply fallen and so they are spending less. Despite this slowdown, Primark’s revenues are still significantly ahead of the same time last year.

The parent company, Associated British Foods (ABF) commented on the disappointing trading of 2011 so far, saying:

“Since the New Year, the performance in all our operations in Continental Europe has been very encouraging but there has been a noticeable slowing down of UK consumer demand.”

However, despite disappointing figures for Primark, UK retail sales did pick up in January, although analysts are warning against taking this information as a sign of recovery. As Hetal Mehta from Daiwa said:

“While we expected there to be some clawback from December’s dismal, snow-hit retail sales, today’s jump is a welcome surprise. But is still far too early to conclude that consumers are weathering the storm … and with the past week’s unemployment figures highlighting the fragility of the labour market, the housing market continuing to weaken and real earnings being hit hard by high inflation, it seems inconceivable that consumer spending will act as the driving force of the economy over the near term.”

There are many opinions about what to expect from the economy in 2011, but for any concrete information, we really have to wait for at least another month. Perhaps by Easter, we’ll have a better idea about the state of the UK. For now, there are a few articles considering the retail sector.
