Just a few years ago, Conab, Brazil’s official crop bureau was busy buying up surplus supplies of Brazilian coffee to support the weak global price of high quality arabica coffee. Over the years Conab has accumulated large stockpiles of coffee in their warehouses. Some estimates put the 2002-2003 stockpile purchases at just under 4 million kg together with 1.9m kg bought in 2007-08. The 2009-10 buffer stock purchases are much higher - exceeding 91 million kg. That is a lot of coffee to hold in reserve!
In theory a buffer stock scheme should be profitable when stocks are purchased at a low price and then off-loaded onto the market when prices are higher. Indeed Conab was planning just such a sale earlier this year before favorable weather and the speculators intervened. Better than expected coffee harvests in Brazil have prompted a steep fall in coffee prices and the buffer stock has postponed an intervention into the market.
The coffee price drop is a far cry from last year. Arabica coffee prices hit a 34-year high in March 2011 amid fears of a shortage. Since then, much has changed. From a peak of $3.089 per pound nearly a year ago, prices are down roughly 40 per cent to $1.851 per pound.
Inventories of high-quality beans remain low, but the threat of a shortage has vanished as Brazil is expected to see a bumper harvest this year. This is in contrast to a number of other coffee-growing countries - but Brazil remains a dominant force in the market.

In the lead up to the 2012 Budget, this short BBC news video clip looks at the cost of a pint of beer and claims that some brewers have weakened their beer to avoid the higher excise duty on higher-strength drinks. There is a neat explanation of the breakdown of beer costs and students may be surprised to find out the amount of tax they pay if they drink a pint! About 95p from every pint goes to the government.
Higher taxes have been one factor bringing down consumption levels. There has been a 13 per cent decline in alcohol consumption per head in Britain since 2004. The percentage of men aged 16-24 who drank more than 21 units per week has fallen from 32 per cent to 21 per cent from 2005 to 2010

This new five minute video report from the Financial Times is excellent on the competitive pressures facing many manufacturing businesses located in southern China. Wages are rising quickly and some manufacturing businesses have already moved either to lower-cost locations within the Chinese economy or to other countries such as Bangladesh and Indonesia.
But there are alternative approaches and this video emphasises the decision that some manufacturers have made to stay put but instead to move up the value chain and produce higher-end, higher-priced products for advanced western markets. Businesses are reluctant to move factories and sacrifice the human capital that has been accumulated over in some cases over thirty years.

Britain is one of the world’s biggest exporters of creative products - from live TV shows and music to books, arts, architecture and films the economy has built up an enviable global reputation for excellence and a growing trade surplus to aid our balance of payments.
Computer games falls squarely into this category but, according to TIGA - the trade association representing the UK’s games industry - unless there is renewed government support, the future of this sector is at risk. TIGA claims that the British games industry is suffering a significant ‘brain drain’ as talented programmers and artists leave the country to work abroad.

Additive manufacturing or 3D printing is an emerging technology that takes product design data which provides a geometric representation of a product such as a pen and that data is then sent over to a machine that allows products to be manufactured ‘on the spot’ typically using additive materials in liquid or powder format.
This TED talk from Lisa Harouni (co-founder of Digital Forming) looks at examples of intricately designed products made using this new and increasingly affordable manufacturing technology. 3D machines can build structures, build replacement parts and parts within parts - the detailed resolution possible is incredible.

This blog provides a link to a new prezi presentation on the economics of solar subsidies - I have been using it as part of my teaching on aspects of environmental economics for Unit 3 AQA but it might also be useful for unit 1 market failure. I have kept theoretical diagrams out of it and plan to build up relevant analytical concepts such as economies of scale, consumer subsidies, economic and social welfare, government failure et al on a normal whiteboard rather than embed them into the Prezi. I hope it is useful.
Follow the tags at the bottom of the blog entry for more recent articles on solar subsidies such as feed-in-tariffs and other environmental economic resources.

Today’s research in the labs can be the harbinger of terrific innovations that change the landscape of consumer product markets in the years ahead. The iPod Nano is a brand but the research behind nano-technology itself might bring about eye-watering improvements in the energy efficiency of devices that are part and parcel of our daily lives.
This brief news report from Al Jazeerah looks at innovation in nano technologies and what might be around the corner. Researchers at IBM have created the world’s smallest magnetic digital-storage device, using just 12 atoms to hold a single data bit of information.

Supply shortages in key growing regions have caused the price of peanuts to surge to record highs. Peanut prices in Europe are 60% higher than a year ago and the cost of peanuts in the USA has more than doubled in the last twelve months. The price spike is the result of lower production from India, Argentina and the United States.

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.
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.

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.

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.

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.

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
