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.”

The following articles consider this issue.

The outbreak of E. Coli has already cost lives, but it is also costing livelihoods of farmers who rely on producing and selling agricultural produce. Immediately following the outbreak in Germany, the blame was put on Spanish producers of cucumbers, which lead to the destruction of tens of thousands of kilos of fresh produce, costing Spain an estimated £177m per week in sales. Although Spain is not the source of the outbreak, the problem has not disappeared and will now affect the whole of Europe: at least until the source is identified. Countries such as Spain, France and Germany are big exporters to Russia and these countries are likely to take a big hit with the Russian health service banning imports of EU vegetables. The impact of this action (together with other countries implementing similar strategies) has not only affected agricultural producers, but is also having wider impacts on other sectors, including transportation. If no-one wants to buy the products, there’s very little use for the companies and indeed drivers to deliver them.

The Spanish economy will be looking for compensation from Germany for the losses they incurred, when sales of fruit and vegetables practically ceased following Germany’s initial accusation. As the Spanish Prime Minister Zapatero said:

“We acted as we had to, and we are going to get reparations and the return of Spanish products to their rightful place. … I believe that any other interpretation or any effort to politicise the huge mistake made by the German authorities is totally unfair.”

The effects of this outbreak have spread to UK supermarkets and producers. The former have reported a slight drop in sales of fruit and vegetables, but have not taken this opportunity to drop the prices paid to British growers, which is particularly important for cucumber producers, given the high production costs. Sarah Pettitt of the National Farmers Union said she was ‘extremely encouraged to hear that the major supermarkets … are not using this unfortunate situation as an excuse to drop prices to British growers.’ In fact some believe that the outbreak could be good for UK producers, as consumers increasingly turn to home-produced products. While the source of the outbreak remains unknown, so does the future of agricultural producers throughout Europe, as well as all those that have any dependence on this huge industry.

Questions

  1. Why have cucumber producers been experiencing falling profit margins in recent years?
  2. Could the outbreak of E Coli bring any benefits to the UK economy?
  3. What are the costs and benefits to Russian consumers and producers from the protectionists measures that have been imposed on EU imports of fruit and vegetables?
  4. Which sectors within the European market are likely to experience the biggest problems?
  5. Explain why the Chairman of the National Farmers Union was ‘encouraged to hear that the major supermarkets … are not using this unfortunate situation as an excuse to drop prices to British growers’. Why would supermarkets have an incentive to do this?

“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?”
