Many UK coal mines closed in the 1970s and 80s. Coal extraction was too expensive in the UK to compete with cheap imported coal and many consumers were switching away from coal to cleaner fuels. Today many shale oil producers in the USA are finding that extraction has become unprofitable with oil prices having fallen by some 50% since mid-2014 (see A crude indicator of the economy (Part 2) and The price of oil in 2015 and beyond). So is it a bad idea to invest in fossil fuel production? Could such assets become unusable – what is known as ‘stranded assets‘?
In a speech on 3 March 2015, Confronting the challenges of tomorrow’s world, delivered at an insurance conference, Paul Fisher, Deputy Governor of the Bank of England, warned that a switch to both renewable sources of energy and actions to save energy could hit investors in fossil fuel companies.
‘One live risk right now is of insurers investing in assets that could be left ‘stranded’ by policy changes which limit the use of fossil fuels. As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.
… As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.’
Much of the known reserves of fossil fuels could not be used if climate change targets are to be met. And investment in the search for new reserves would be of little value unless they were very cheap to extract. But will climate change targets be met? 
That is hard to predict and depends on international political agreements and implementation, combined with technological developments in fields such as clean-burn technologies, carbon capture and renewable energy. The scale of these developments is uncertain. As Paul Fisher said in his speech:
‘Tomorrow’s world inevitably brings change. Some changes can be forecast, or guessed by extrapolating from what we know today. But there are, inevitably, the unknown unknowns which will help shape the future. … As an ex-forecaster I can tell you confidently that the only thing we can be certain of is that there will be changes that no one will predict.’
The following articles look at the speech and at the financial risks of fossil fuel investment. The Guardian article also provides links to some useful resources.

Ever been to the cinema and found it almost empty? And then wondered why you paid the full price? Perhaps you’ve taken advantage of Orange Wednesday or only go if there’s a particularly good film on? Often it might be cheaper to wait until the film is out on DVD!
Going to the cinema can be an expensive outing. The ticket, the popcorm, a drink, ice cream – it all adds up! Orange Wednesday has recently disappeared and this will definitely have an impact on consumption of movies at your local Odeon, Vue or Showcase. The impact will be on how many seats are left empty.
However, a new app could be set to generate revenues for the cinema and provide cheaper entertainment for your everyday consumer. This new app will allow cinemas to send out alerts to people in the local area advising them that a screening will have many empty seats. What’s the incentive? Perhaps a discount, or some food. But, why would they do such a thing?
If a movie is being shown at a cinema, there will be a large fixed cost. However, what happens as each additional consumer enters the theatre? Does the cost to the cinema rise? Perhaps there is a small cost with more cleaning required, but the additional cost of actually showing the film if there 11 rather than 10 people is almost (if not equal to) zero. That is, the marginal cost of an extra user is zero. Therefore, if there is a screening with many empty seats, wouldn’t the cinema be better to offer the seats for half price. After all, if you can earn £5 from selling a ticket and the additional cost is almost zero, then it’s better to sell it for £5 than not sell it for £10! The following article and video from BBC News considers this new app and other strategies to maximise cinema usage!
Apps in pockets, bums on cinema seats BBC News, Dave Lee (27/2/15)
Questions
- What would the budget constraint look like for a cinema where a discount was offered if you purchased two cinema tickets and then received the third ticket for half price?
- Why is the marginal cost of an extra user at the cinema almost zero?
- If the MC = 0, does this mean that a cinema is a public good?
- How will this new app allow a cinema to increase total revenue and profit?
- If it is cheaper to buy a DVD rather than go to a cinema, why do people still go to the cinema?
Over 90% of UK households buy their gas and electricity from one of the ‘big six’ energy suppliers – British Gas (Centrica), EDF, E.ON, npower (RWE), Scottish Power (Iberdrola) and SSE. The big six are currently being investigated by the Competition and Markets Authority (CMA) for possible breach of a dominant market position.
An updated ‘issues statement‘ summarises the investigation group’s initial thinking based on the evidence it has received. In paragraph 16 it states:
Comparing all available domestic tariffs – including those offered by the independent suppliers – we calculate that, over the period Quarter 1 2012 to Quarter 2 2014, over 95% of the dual fuel customers of the Six Large Energy Firms could have saved by switching tariff and/or supplier and that the average saving available to these customers was between £158 and £234 a year (depending on the supplier).
Between 40% and 50% of customers have been with a supplier for more than 10 years. The companies are thus accused of exploiting these ‘loyalty’ customers, many of whom are too busy or ill-informed to switch to an alternative supplier. According to the uSwitch article below:
This is a particular issue for the most vulnerable of customers, including the elderly, who view switching as ‘impossible’.
But the elderly were not the only consumers losing out; the CMA found that those customers most likely to be on expensive standard tariffs were less educated, or on lower incomes, or single parents, and did not necessarily have access to the Internet.
And the problem of penalising ‘loyalty’ customers who do not shop around applies in other industries, most notably banking. People who regularly switch savings accounts can get higher interest rates, often for a temporary ‘introductory’ period. Similarly, people who regularly transfer credit card debt from one card to another can take advantage of low interest rate, or even zero interest rate, deals for an introductory period.
Returning to the energy industry. Is the problem one of oligopoly? Do the big six have too much market power and, if so, what can be done about it? Should they be split up? Should regulation be tightened? Should new entrants be encouraged and, if so, what specific measures can be taken? The following articles explore the issues and possible policies.

In the UK, we take it for granted that if you need to see a doctor, you go and give little, if any thought, to the cost. It may be petrol costs, time off work or the cost of a prescription, but beyond that, receiving treatment is free at the point of use. Funded through a progressive tax system, the NHS is seen as being one of the more equitable health care systems.
When a mother gives birth, the main thing she will have to worry about is the labour – and not whether to have certain painkillers or stay an extra night, because of the cost.
The International Federation of Health Plans (IFHP) looked at data on the cost of giving birth, based on insurance company payments. For someone living in the UK, the figures make for quite astonishing reading. In the USA, a normal delivery will cost $10,000, while a caesarean totals $15,000, meaning that giving birth in the USA is the most expensive place in the world. The article linked below takes the case of Mari Roberts, whose total delivery bill came to over $100,000. The insurance did cover it, but that’s not always the case. Medical bills in the United States are one of the leading reasons for bankruptcy and with these types of figures, perhaps it’s hardly surprising.
Other countries also see high costs for delivery, where expectant mothers really do need to give consideration to the length of their stay in hospital and perhaps even whether they are willing to forgo a pain-relieving drug and save some money. There is often said to be an efficiency–equity trade-off in the area of healthcare, with countries offering a free at the point of use service delivering an equitable system, but with a lack of responsiveness to the demands of the patients. In the UK, you don’t pay to see a doctor but, with a ‘free’ service, demand is understandably very high, thus creating a shortage and waiting lists. In countries, such as the USA, a higher price for treatment does limit demand, creating more inequity but a responsive system.
There are certainly lessons that can be learned from all health care systems and living in a developed country, we should certainly consider ourselves lucky. There are many countries where access to even the most basic health care is a luxury that most cannot afford. So, where does have the best health care system? I’ll leave that to you.

When an industry produces positive externalities, there is an argument for granting subsidies. To achieve the socially efficient output in an otherwise competitive market, the marginal subsidy should be equal to the marginal externality. This is the main argument for subsidising wind power. It helps in the switch to renewable energy away from fossil fuels. There is also the secondary argument that subsidies help encourage the development of technologies that would be too uncertain to fund at market rates.
If subsidies are to be granted, it is important that they are carefully designed. Not only does their rate need to reflect the size of the positive externalities, but also they should not entail any perverse incentive effects. But this is the claim about subsidies given to wind turbines: that they create an undesirable side effect.
Small-scale operators are encouraged to build small turbines by offering them a higher subsidy per kilowatt generated (through higher ‘feed-in’ tariffs). But according to a report by the Institute for Public Policy Research (IPPR), this is encouraging builders and operators of large turbines to ‘derate’ them. This involves operating them below capacity in order to get the higher tariff. As the IPPR overview states:
The scheme is designed to support small-scale providers, but the practice of under-reporting or ‘derating’ turbines’ generating capacity to earn a higher subsidy is costing the taxpayer dearly and undermining the competitiveness of Britain’s clean energy sector.
The loophole sees developers installing ‘derated’ turbines – that is, turbines which are ‘capped’ so that they generate less energy. Turbines are derated in this way so that developers and investors are able to qualify for the more generous subsidy offered to lower-capacity turbines, generating 100–500kW. 
By installing derated turbines, developers are making larger profits off a feature of the scheme that was designed to support small-scale projects. Currently, the rating of a turbine is declared by the manufacturer and installer, resulting in a lack of external scrutiny of the system.
The subsidies are funded by consumers through higher electricity prices. As much as £400 million could be paid in excess subsidies. The lack of scrutiny means that operators could be receiving as much as £100 000 per year per turbine in excess subsidies.
However, as the articles below make clear, the facts are disputed by the wind industry body, RenewableUK. Nevertheless, the report is likely to stimulate debate and hopefully a closing of the loophole.
