British Petroleum has decided to exit the solar energy energy industry claiming that the business has become unprofitable because of excess supply and falling prices. In 2011 a number of solar firms have gone out of business including California’s Solyndra and Germany’s Solon. BP will focus instead on investing in other renewable energy sectors including wind power and biofuels.
Whilst the decision by BP to exit the industry appears significant, infact total global investment in solar power continues to rise. MidAmerican Energy Holdings owned by Warren Buffett have agreed to purchase a $2 billion solar project under development in California and a 49 percent stake in a $1.8 billion plant in Arizona.
Google Inc. and KKR & Co have announced a joint venture to pump money in four California solar power plants with total capacity of 88 megawatts. The powerful search engine business uses a huge anount of energy every year and has committed itself to large scale investment in renewable energy supplies to help power their server farms.

Unit 3 Micro: Oligopoly and Duopoly in Bus Markets
The UK Competition Commission has published an important report into the market structure of local and regional bus services in the UK, twenty five years after the industry was deregulated and largely privatised. Coverage of the report can be found here (BBC news).
Largely as a result of a long-term process of consolidation through merger and acquisition, the UK bus industry is found to be highly concentrated with five businesses dominating the sector even though more than 1,200 businesses provides services.
The five largest operators (Arriva, FirstGroup, Go-Ahead, National Express and Stagecoach) carry 70 per cent of those passengers. The CC also found that head-to-head competition between operators is un-common and that-on average-the largest operator in an urban area runs 69 per cent of local bus services - effectively a monopoly position.

This excellent news piece from Ben Cohen at Channel 4 looks at the increasingly aggressive patent war being fought by the manufacturers of the world’s leading mobile phone and tablet devices - the most profitable products in the digital economy. “Where once the giants (Google and Apple) competed on features, they now compete on patents.”
The news feature looks in particular at the intellectual property surrounding the slide-screen technology used by millions to unlock a device. Apple claims the IP to this but a video tracked back to twenty years ago suggests that developers were already thinking of something remarkably similar long before the iPhone came into existence. Can the makers of Android defend legal claims from Apple that their IP has been infringed? And who will end up paying for the enormous legal fees and possible extra licencing costs?

Unit 1 Micro: Empty Housing and Economic Efficiency
Channel 4 recently focused on the causes and effects of the hundreds of thousands of empty homes in the United Kingdom. Why is it given persistent shortages of affordable housing that perhaps a million homes lie empty and unused whilst an estimated two million families are in severe housing needs. New housebuilding has collapsed and in Britain we are building 100,000 fewer new houses every year than we need just to keep up with the changing mix of households and demographic change.
An interesting exercise is to show students some of the Channel 4 Campaign videos and then get them to put together policy ideas as to how to reduce the volume of empty homes and reduce the length of housing waiting lists.
Links to some of the Channel 4 videos can be accessed below:

This five minute video is superb for illustrating economies of scale in the production - we take a trip through the United Biscuit factory to see how millions of products are made every day. The commentary is a little simplistic but as a visual aid it is brilliant. A great example to use of capital intensity in production and the nature of supply curves and the elasticity of supply. Here is the link to use
Unit 3 Micro: Tacit Collusion in the Supermarket
What do students make of the current price match / big price drop schemes offered by many of the leading food retailers in the UK?
On the surface the brand price match scheme shown in the picture below looks like a good deal for consumers in this time of financial hardship and distress.
But what it this ‘parallel pricing’ serves merely as a form of tacit collusion with prices on a range of products actually higher than they might be without the facade of price comparisons and discount voucher compensation?
Unit 3 Micro: Brand Loyalty in Mobile Phones
Brand loyalty is hugely important in all kinds of industries and markets. The costs of acquiring a new customer vastly outweigh the expense of selling more to existing buyers and most of the mobile phone suppliers in this oligopolistic industry focus an enormous effort in building brand identity and brand loyalty to reduce the rate of customer churn (people who switch brands).

Around this time of my micro course my students look at maximum prices (price ceilings) in different markets. There are still plenty of contemporary examples to consider, for example salary caps for executives, caps on the cost of mobile phone texts and roaming charges, rent ceilings etc. But here is a resource that will be of special interest to football-loving economists, namely the 50th anniversary of the ending of the maximum wage in football. The Independent has this nifty set of graphics looking at landmarks in wages of top footballers over the years. Click on: The maximum wage and football’s money trail
Government Plans to boost the Housing Market
The Government has announced today a scheme to help first time buyers on to the property ladder. It has been reported widely in the press with mixed reactions. The BBC article outlines the main proposals (here is the link to The Daily Telegraph). It is interesting from a political point of view that this government should chose to intervene in this market, though perhaps we should not be too surprised as it was the Conservatives that brought in the ‘Right to Buy’ legislation in 1980.

I am trying to get my head around this example of pasty prices that I encountered at Waterloo Station on Tuesday night. The vendor is selling a large pasty for £3.90 and “The Big One” for £4.00 - a difference of just ten pence? Why not charge more? Or at least cut the price of the large pasty to something like £3.30 to encourage people to pay the £4.00 option? Am I missing something here?
I asked the guy running the concession “what is the difference between the large pasty and the big one?” His cogent reply put me right “The big one is bigger!” I bought the large pasty because as far as I can see, there is no difference in size.
Applications of Elasticity
Once students have understood the theory of the different elasticities, an important progression is being able to apply it to different markets.
One exercise that I use with my iGCSE and AS groups is as follows:
Unit 1 Micro: Asymmetric Information - Buying a Used Car
An autumnal hat tip to Kevin Hinde at Durham Business School for spotting a new report from the Office of Fair Trading which finds that the market for second-hand, used cars remains the biggest source of complaints from customers. Nationally over 56,000 people have complained to the OFT-managed Consumer Direct in the year to date with 70 per cent of the complaints relating to faults with the cars and over 13 per cent about misleading claims or omissions by the seller. The used car market is a classic example of asymmetric information and the risks of consumer welfare being damaged by fraudulent selling and sub-standard service. The OFT have released a short film on customer rights that might be a good teaching resource to use when covering this topic.
Unit 1 Micro: Has the time come for a Tobin Tax?
This week I am setting my AS micro students a question on proposals for a Tobin Tax - partly because it is hugely topical and also as a way of developing their evaluation skills on paper and coming to a reasoned final conclusion. Here are some of the links to suggested reading and some video shorts on this topic:

Have you got £40,000 or £50,000 to spare on a Christmas present? A hat tip to Freddie Drapkin for spotting these examples of products perfectly suited to status races and ostentatious consumption!
Glass pool table (£39,000)
£45,000 - luxury table football table
World’s largest jigzaw puzzle (£200)
And for the lazy tea drinkers among you - try this!
Unit 3 Micro: Unilever hit by rising costs
Here is a good example of a global giant in consumer products whose profitability has been affected by external headwinds over which it has little control.
The Anglo-Dutch business Unilever - the world’s second-biggest consumer-goods company – has announced that profitability might fall in 2011 even after it increased prices to offset soaring costs for the commodities used to make its products.

When is electricity demand highest in the UK? The answer comes at the end of the blog!
The UK government is committed to the rolling out of smart energy meters between now and the end of 2020. Millions of homes will have smart meters installed which track how much electricity you use and when you use it - the installation cost is approximately £350 per unit although this may come down with the utilisation of economies of scale. Smart meters will give consumers and the utility businesses minute-by-minute information about energy consumption and this could fast-forward the launch of time of use pricing tariffs for us all in the years ahead. It will mark a move away from flat-rate tariffs towards fully-fledged peak and off-peak pricing.
At the moment around one in ten households are on Economy 7 tariffs which offers lower prices for electricity used during off-peaking times in the late evenings and early mornings. Economy 7 seems to have been around for as long as CEEFAX and if you understand that you are giving your age away!

Thames Water has plans for a super sewer running 20 miles from Hammersmith to Beckton but the plan has come up against intense opposition from many local resident groups. It is a good example to use of cost-benefit analysis in action with a project that will directly affect millions of people living and working in the capital. There is an almost unending list of stakeholders involved in the debate.

Here is an example of economies of scale in production. Microsoft’s motion-sensing camera the Kinect was one of the fastest-selling consumer electronics device in history when it was launched in November 2010. In a report on the FT’s technology blog, Dennis Durkin, Xbox chief financial officer, is quoted as saying that economies of scale have been the major factor driving down the unit price of Kinect from $30,000-$40,000 when it was under development two years ago to $150 now.

Google has announced that heavy users of the Google maps application will now be charged - it will be interesting to see if this move from a zero price targeted at websites that make extensive use of the Google Maps coding will affect demand for the program.

I tweeted earlier on today asking economics teaching colleagues what examples they like to use when teaching the topic of price discrimination under conditions of monopoly / imperfect competition. Thank you to everyone who contributed!
Unit 3 Micro: Price Discrimination in the E-Book Market
Seth Godin’s Domino Project is an attempt to re-fashion the way in which e-books are published, sold and priced. This blog is particularly interesting for teachers and students who consider different forms of price discrimination. It proposes (at least) three different price tiers:
$1.99 ebooks - a clearing price for the majority of e-books
$5 ebooks. This is the price for bestsellers, hot titles and academic titles required by courses
$10 - $20 ebooks. This is the price you will pay to get the book first, to get it fast, to get it before everyone else
What do you think? How do you see e-book pricing tactics evolving as the market grows? The UK Office of Fair Trading is currently investigating the market for e-books in the UK amid allegations of price fixing / collusion by several leading publishers. You can access the OFT investigation using this link.

By way of background - new research has found that the average e-book price of front-list e-books across the world was €10.50 net of taxes. The average price of UK frontlist e-books was €10.80, €1.50 more than equivalent US titles, but less than those in Germany, Spain and France.
Unit 1 Micro: Is the Sun Dipping on Solar Subsidies?
To promote the expansion of renewable energy sources, many governments have introduced subsidies for consumers who install solar panels.
In April 2010, the Labour government introduced generous feed-in tariffs to encourage households to install solar photovoltaic systems. Anyone spending £13,000 up front to fit a system to their home was paid 41.3p per kilowatt hour (kWh) generated – enough to earn them a typical annual income of £900 a year in payments, on top of a £140-a-year saving in reduced electricity bills. The big six energy companies are required by law to pay householders who generate their own energy.
It looks like the days of generous subsidies for solar panels are coming to an end and there is a rush on to install them before the feed-in-tariff system is changed.

When teaching price elasticity of demand, here is a good article on the BBC today on the effect of higher university fees on demand for higher education. Good for discussion of how PED will differ with respect to different types of consumer and for different types of universities, as well as the cross price elasticity of demand with foreign universities.

Food prices are now rising by up to 10% a year in Britain and Europe and a new forecast from the United Nations predicts that prices can be expected to rise at least 40% in the next decade. Whilst conventional theories of changes in supply and demand conditions can be used to explain some of the increase in food prices, many economists are concerned that speculation by hedge funds and other investors has amplified the natural volatility of prices driving food prices away from fair values and contributing to a huge rise in global food poverty and hunger. These days, cocoa, fruit juices, sugar, staples, meat and coffee are all now global commodities, along with oil, gold and metals.
Is this the moment to legislate to limit the scope for speculative activity in food markets? The video below provides an excellent introduction to speculation in food markets - it features Neil Kellard, Professor in Finance at the University of Essex

Changes are afoot for the UK household mail industry - a sector that is often used by teachers as an example of a near monopoly in the UK. In 2010, 16bn letters were delivered to 28.2m addresses. Royal Mail was responsible for delivering over 99% of these. The total UK household and business mail market comprises around 16bn items and £6bn to £7bn per annum of revenue. Royal Mail has a market share by revenue of over 90%.
Just a few years after deregulation of the sector, the industry regulator Ofcom has produced a consultation document that is likely to give the Royal Mail more freedom in setting the prices of stamps. At present, the Royal Mail loses more than £2 million a week operating its letters business. Increasing competition from new entrants for bulk mail sorting allied to a shift towards email and text have contributed to a 25% decline in postal volumes since 2006. Household spending in Britain on postal services has fallen to just 40p a week. The 2010 Hooper Report on the postal sector, mail volumes are expected to continue to decline globally by between 25% and 40% in the next five years

On paper, it sounds like a totally reasonable price strategy from the market leader in an oligopolistic market - after announcing their worst sales figures in nearly 20 years, Tesco’s came out with a price cut promotion “The Big Price Drop”. The supermarket – which has pledged to spend £500 million on the high-profile promotion – has promised customers that it would reduce the price of 3,000 essential products across its stores.

Here is a nice example to illustrate the varying effects of the recession on the economy… A growing influx of high-spending foreign tourists powered Harrods through the £1bn sales barrier for the first time… whilst Poundland has also has reported a 26 per cent boost in revenues to £642m. A good example to use in discussion of goods and services that have different income elasticities of demand. Read the article at the FT here.
