Pub smoking ban: 10 charts that show the impact – BBC News

It’s 10 years since smoking in enclosed public spaces was banned in England. What has the impact been?

This is an excellent article, written by an old uni friend of mine, exploring the impact of restrictions on where people can smoke. Cigarettes are considered by economists as a demerit good, one that generates negative externalities through consumption. These externalities, costs to a third party, can occur in many ways, for example, the adverse effects on the health of bar workers. The ban has helped to reduce the number of people smoking in the UK, although it still remains predominantly a habit of the poor. However, it is important to note that changes to packaging legislation and increased duties may have helped to reduce the number too. A reduction in the number of smokers helps to reduce the pressure on the NHS of treating tobacco-related illness, although, of course, if people live longer then other, perhaps more expensive treamtents, need to be paid for. An unintended consequence has been the impact on pubs, a number are closing creating unemployment in the process. Again, however, other factors, such as a general reduction in alcohol consumption and cheaper substitutes, i.e. buying beer from a supermarket, will have had an effect.

This is a nice example of how a number of government interventions can be used to correct the market failure associated with a demerit good.

The deep sea is a frequently used example of common access resources that is over-exploited  – a case of ‘The Tragedy of the Commons’ originally coined by ecologist, Garrett Hardin. It stems from a simple idea that the benefits of over-fishing (increased revenues) are private while the costs are shared. Unfortunately, such an approach is unsustainable as a result of over-consumption and subsequent market failure. Technology is both a cause of the problem and a solution too. Larger trawlers increase catch size reducing the number left to breed. However, new technology can help to monitor, collect information and enforce regulation. One extreme proposal is to ban fishing in set zones, this has been effective in some trials allowing fish to ‘restock’ and improve sustainability. Clearly, an international agreement is required, but this is hard, especially given the current rise in nationalism and self-interest. The WTO are working on something, but have been doing so for several years.

A standard market failure essay question would ask you to consider whether government intervention is required to correct a market failure or would it be best left to market forces. This article explores the role of the latter in the context of air pollution and the growth in the number of firms producing goods to both monitor and reduce the impact of air pollution.

The Economist | Information asymmetry: Secrets and agents

The Economist starts its series of economics briefs with information asymmetry, its beauty lies in its simplicity. Very recently my car failed its MOT. The garage called to say repairs would cost £580 – seeking to exploit my imperfect knowledge of prices and the mechanics of my car. A few phone calls later and I managed to find a local garage willing to do the same repairs for £400. A return call to the original garage found that they would match the price, a saving of £180. I suspect many would not have bothered, I almost said “go ahead” myself, converting consumer surplus into producer surplus in the process. George Akerlof, in his seminal work ‘The market for lemons’, explains that information asymmetry is a very common cause of market failure, when economic thinking at the time was that buyers and sellers had sufficient access to information to make rational decisions, clearly rubbish.

As Harmony of the Seas sets sail from Southampton docks on Sunday she will leave behind a trail of pollution – a toxic problem that is growing as the cruise industry and its ships get ever bigger

Super-sized cruise-liners offer their owners significant economies of scale, which helps to bring down unit costs and prices, making cruising affordable to the masses. However, it comes with a social cost that is not reflected in the market price. Cruise ships emit very large levels of toxins that adversely effect the atmosphere, in particular where they dock. In addition to the noise and air pollution generated by the liner itself, local residents can also expect to see increased congestion as passengers come and go. Clearly some benefit from increased trade thanks to the spending of holidaymakers, but does this increased income cover the additional external costs?

Port Talbot & A’level economics

A’level economics students frequently moan  that what they have been taught is not relevant to what is going on around them while economics teachers complain that students do not relate what they have been taught to the real world!

The recent events at Port Talbot provide an ideal example to use economics concepts.

The multiplier can be used in assessing the costs to the area should Port Talbot close since not only will steel jobs be lost if the plant closes, additional jobs will also be at risk as steel workers suffer lower disposable income and cut back on expenditure,  particularly in non-essential areas.

In considering the type of unemployment created, one can use the idea of structural unemployment since many of the steel workers affected will not have the skills needed in newer, growing industries.

The possible closure of the plant is relevant to the arguments about the benefits of free trade and the theory of comparative advantage whereby UK steel purchasers benefit from cheaper steel imports from China which need to be set against the  job losses among UK steel producers. This aspect can be expanded to consider whether the Chinese are dumping steel on the world market and, if so, what action should be taken, especially in the light of the tariffs on Chinese steel imposed by the USA and those imposed by China on imports of steel from the EU and elsewhere.

A final example is in the  field of market failure where Tata have complained that the UK Government’s environmental policies have raised energy prices and helped make UK produced steel (and heavy industry generally) uncompetitive. UK electricity prices are almost double those in the rest of the EU and more than double those in China and while these high prices help to subsidise renewable forms of energy, they make life difficult for UK firms.
