Unit 3 Micro: Inside the iPhone and Intellectual Property
This is a remarkable video featuring Geoff McCormick, director of UK design firm The Alloy that looks inside an iPhone at the component parts. Each and every iPhone contains thousands of patented components, ideas, designs and processes. Fantastic when teaching about the economics of intellectual property and the patent wars dominating the courts.

For those of you who missed this week’s panorama “Poor America” it is well worth 30 minutes of your time. Students often assume that a high GDP per capita always leads to the good life for all- this programme highlights inequality well.
Video clip: Poor America: ‘Some kids are making ketchup soup’
The Panorama programme on America’s poor is available to view for the next 12 months - click here

Public goods provide an example of market failure resulting from missing markets.
The characteristics of pure public goods are the opposite of private goods:
1. Non-excludability: The benefits derived from pure public goods cannot be confined solely to those who have paid for it. Indeed non-payers can enjoy the benefits of consumption at no financial cost – economists call this the ‘free-rider’ problem. With private goods, consumption ultimately depends on the ability to pay
2. Non-rival consumption: Consumption by one consumer does not restrict consumption by other consumers – in other words the marginal cost of supplying a public good to an extra person is zero. If it is supplied to one person, it is available to all.
3. Non-rejectable: The collective supply of a public good for all means that it cannot be rejected by people, a good example is a nuclear defence system or flood defence projects.
There are relatively few examples of pure public goods. Examples include flood control systems, some of the broadcasting services provided by the BBC, public water supplies, street lighting for roads and motorways, lighthouse protection for ships and also national defence services.

It has been a bit chilly in the UK for the last few days, but nothing compared to the temperatures as low as -35 which have hit parts of central and eastern Europe. Of course, they are used to far colder winters than us, and have different ways of dealing with the weather, but reliance on gas supplies from Russia for the majority of their heating fuel leaves countries including Bulgaria, Serbia and Bosnia vulnerable to disruption in that supply.

Justin Rowlatt from the BBC has been investigating some of the remarkable progress being made in controlling deforestation in Brazil. The battle focuses on an area known as the “arc of destruction” and the video reports here show the impact of a government making a clear commitment to tackling the issue and backing it up with force and with incentives.

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 news report looks at the human cost of an example of the tragedy of the commons - illegal logging in the south Philippines which contributed to tens of deaths from the effects of flash flooding. Ecosystems and economic prospects are damaged at the same time because of failures in environmental management.

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.

I do my level best to avoid the processed meat aisles in the supermarkets - or at least the lower end of what is on offer (I remember once the 5pence sausage that was a guaranteed 2 per cent pork!). But perhaps excessive consumption of processed meats - much of which finds a way into the traditional Full-English might be doing people much more harm than good? Follow this BBC news report for more details.

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.

The tunnelling equipment involved in CrossRail - Europe’s biggest civil construction project - is immense in every way! This BBC news video of the earth cutting machinery is a brilliant visual to use when teaching economies of scale or introducing the concept of physical capital! The machinery is made in Germany naturally!
Unit 3 Micro: Prezi on Environmental Economics
This term I am teaching some environmental economics to my A2 groups. The link below provides access to a Prezi on aspects of environmental issues such as the Tragedy of the Commons and the economics of waste and pollution. I will be updating and extending the Prezi as I develop the lessons. I hope that it is useful. I will try to include as many examples as I can on European and Global issues to do with environmental issues - the beauty of a Prezi of course is the flexibility of ordering course materials and the chance to embed lots of vivid You Tube clips and images into the resource.

If a criminal steals metal from a building yard or a jewellers the impact is relatively isolated but when metal theft extends to lifitng metal from roofs, railway lines and many other public buildings, thousands are inconvenienced and left to pay the cost - negative externalities are clear.
This news report from Al Jazeera looks at the growing economic and social problem of metal theft in London and a second video report from Channel 4 news looks at the external costs of copper theft from cables on the rail network that delays services and puts lives at risk. What are the best options for dealing with this crime epidemic? The Met Police has set up a specialist metal theft unit as part of their response.

The global financial and economic crisis has created many problems for airlines - falling business and 1st class passenger revenues, increased insurance costs, problems in getting loan finance, volatile exchange rate and the challenges of steep increases in aviation fuel prices to name just a few. We could also add the shockwaves from the spring 2011 Japanese earthquake and tsunami, the Arab Spring and a decline in tourism, and the steadily deteriorating global economic outlook - with the Euro Zone crisis threatening a second recession for Western Europe.
But discount airlines - carriers that offer no-frills and charge plenty for extras on top of low basic fares - seem to have fared pretty well despite the turbulent conditions. Many passengers now appear willing to sacrifice luxury for cheaper flights and there are plenty of news stories of low-cost airlines in Europe, Asia and Africa who are announcing expanded route maps for 2012 and beyond.
What economic factors help explain the continued expansion of low-cost airline carriers?
