Boasting a steering wheel that doesn’t steer, an in car radio that is an optional extra and acceleration powers that - on a good day - can take you from 0 to 60 in less than three minutes, the Lada has for a long time been a figure of fun in global motoring circles. But production is coming to an end following a collapse in sales. As is often the case, news of the demise of the Lada has prompted increased interest among younger urban consumers whose DNA is to go against the grain and drive something that is sturdy, mercifully free of corporate design features and most of all, tremendously cheap.

In a fresh move to reduce consumption of cigarettes, legislation has come in force banning the displays of cigarettes for sale in large retail stores. The display ban will apply to shops of more than 280 sq m (3,014 sq ft). Newsagents and small stores can display cigarettes until 2015, giving them time to refit shelves and cabinets.. It is part of the armoury of interventions that have been tried over the years to change consumer behavioural - from real terms increases in cigarette taxes to bans on advertising and ever-stronger advertising and health campaigns. The focus of the ban is to influence younger smokers by removing cigarettes from point of sale display - will it be effective?
This news report below from Al Zajeerah looks at the new measure

The supply of health care in the UK is an important economic, social and political issue. Demand for health care treatments grows year by year as the population expands, ages and as incomes rise. For millions of people private health care is regarded as a necessity even though the NHS provides a vast range of services free at the point of use. Treatments such as cosmetic surgery, hand surgery, laser eye treatment, physiotherapy, weight loss services and hip and knee replacements are offered by a range of private sector providers in addition to state health care facilities.

For several years the European Union Competition Commission has been targeting the oligopolistic mobile phone industry accusing it of damaging consumer welfare with high roaming charges when people are travelling and working within Europe. Yesterday marked another landmark in the battle between the regulators and the industry.

No one is in any doubt that smoking kills and for half a century the Royal College of Physicians has been warning of the damaging health consequences of nicotine consumption and addiction. They continue to campaign for higher prices and tougher laws on advertising and packaging to curb consumption - even today one fifth of the adult population smokes. Smoking continues to kill around 100,000 Britons each year and unless smokers give up their habit, 100 million years of life will be lost in the UK, according to experts. Channel 4 news reports on changing social norms and the battle to change behaviour. A good historical perspective on information gaps.

Here is a one minute news clip packed with nuggets of good business economics. Profits have more than doubled at German car-maker Volkswagen after the company delivered a record number of vehicles last year. It delivered more than 8.2 million vehicles, up almost 15% on 2010. Listen and watch for information on their acquisitions and competitive strategy especially when targeting fast growing markets in emerging economies especially China, India and Brazil.

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.

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?

If you are a fan of laminate flooring, wood panelled walls or neat wood-based fencing for the garden, the chances are that you will be paying higher prices in the years ahead. Despite the Britain offering a temperate climate for a plentiful supply of wood and a well organised system of land registry and plantation management, the UK market price of different types of timber has shot up over the last two years.

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: Patent Wars- A Touchy Subject for Apple
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:

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).

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.
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 3 Micro: Time of Use Pricing for Energy
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!

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.
