Here’s a question that goes to the heart of economics and the social sciences generally: how desirable is the market system?
Our lives are dominated by markets. Whether in working or consuming, we operate in a market economy in which money is exchanged for goods or services. But also financial and product markets determine much of the structure of society, where most things seem to have a price.
But whilst, as a positive statement, we can say that money and markets are all around us, does that make them desirable? Markets provide signals and incentives; but are the signals the right ones? What are the incentives and how do we respond to them? And are these responses optimal?
You will probably have studied various ways in which markets fail to provide the optimal allocation of resources. But what are the limits of markets as a mechanism for social choices? And is there some more fundamental issue about the morality of a society that is organised around markets?
These are questions considered in the following podcast. It is an episode from BBC Radio 4’s Start the Week programme, hosted by Andrew Marr, with guests Michael Sandel, Diane Coyle and Grigory Yavlinksy. Here are the programme details:
Andrew Marr discusses the relationship between markets and morals with the political philosopher Michael Sandel. In his latest book, What Money Can’t Buy, Sandel questions the dominance of the financial markets in our daily lives, in which everything has a price. But the economist Diane Coyle stands up for her much maligned profession, and points to the many benefits of a market economy. The Russian economist Grigory Yavlinksy argues against viewing the world of money as separate from culture and society: he believes the financial crisis was merely a symptom of a wider moral collapse, and that it is time to examine the way we live.

- Is the market society a relatively new phenomenon, or does it go back hundreds of years?
- To what extent is the greed expressed through markets and encouraged by markets affecting/infecting society and human relationships generally?
- What is the role of morality and trust in determining the desirability of market relationships?
- To what extent does a market economy allow people, rich and poor, to live separately from each other and not interact as joint members of society?
- What are the value systems promoted by marketisation? Should certain aspects of human life be outside these value systems?
- To what extent is the crisis of capitalism a crisis of economics?
- What policy alternatives are there for rebalancing society?

John Von Neumann was a mathematician and one of his many accolades was applying mathematics and his observations of traditional games to create a new discipline – Game Theory. This involves a mathematical approach to decision making whereby different strategies can be assessed. It a tool that not only can be used in Economics, but also can be applied to a broad range of areas and fields of study.
Just as I arrived at work, I was listening to Radio 4 and heard the introduction to the programme In our Time. This one in particular caught my attention because of the name mentioned – Von Neumann, and after arriving in my office I then listened to the discussions surrounding game theory.
The main link is to the discussion from BBC Radio 4, led by Melvyn Bragg, with guests: Ian Stewart, a Professor of Mathematics from the University of Warwick; Andrew Colman, a Professor of Psychology at the University of Leicester and Richard Bradley, a Professor of Philosophy from the LSE. I’ll keep it brief and simply say enjoy!

Binge drinking is a problem that has seen much attention, especially with regards to minimum price controls. However, in this blog, we consider attention in this sector concerning taxation on beer.
Alcohol is widely considered to be a de-merit good with negative externalities imposing external costs on society. This is one of the reasons why taxes are imposed on alcoholic beverages. By increasing production costs to the firms providing these drinks, prices rise and hence the policy aims to discourage consumption.
During the recession, many businesses have seen demand fall and one sector hit particularly hard because of this and very high tax rates has been the local pub community. Duty on beer has increased since 2008 by some 42%. As such, many rural and suburban communities have seen their local watering holes close down and this has led to a campaign by CAMRA to force a debate in Parliament, as a means of protecting ‘one of Britain’s oldest and best loved institutions’. Data suggests that 12 pubs per week are closing down, thus the future of the industry is now under threat. This may also have further damaging effects on local communities, as it may adversely affect the social aspect of communities. Camra’s Chief Executive, Mike Benner said:
‘Whether situated in a small village, city high street, or on the edge of a housing estate, pubs are so central to our society that whole communities can grow around a particular pub.’
According to a study, pubs in Lancashire and the West Midlands have been hardest hit by the pub closures. If pubs don’t pass the tax increase on to consumers in the form of higher prices, then they must bear the burden. If they do pass the tax rises on to consumers then the larger chain firms can increase their market share by selling at a lower price. They are also facing growing pressure from the supermarket industry, which are able to sell cheap alcohol, also contributing to going to the pub becoming an ‘unaffordable activity’. The following articles consider this industry.

Questions
- Illustrate the effect of a tax being imposed on a product such as beer.
- In this market, would the tax be more likely to be borne by the producers or consumers? Explain your answer and illustrate on the previous diagram why this is the case.
- Why are supermarkets able to compete local pubs out of the alcohol market? Do you think a minimum price will have any effect?
- What is a de-merit good? Illustrate the concept of a negative externality on a diagram.
- Explain how a de-merit good causes the market to fail. To what extent does the tax on beer solve the market failure?
- Why are there likely to be adverse effects on local communities? Could this have an adverse effect on economic activity in the area?
Oligopoly: it’s a complex market structure and although closer to the monopoly end of the ‘Market Structure Spectrum’, it can still be a highly competitive market. The characteristics are well-documented and key to the degree of competition within any oligopoly is the number of competitors and extent to which there are barriers to entry.
The greater the barriers and the fewer the competitors the greater the power the established firms have. This can then spell trouble for pricing and hence for consumers. The following articles are just some examples of the oligopolies that exist around the world and some of the benefits and problems that accompany them.

Vodafone has offered to purchase Cable & Wireless Worldwide (C&WW), with Vodafone paying 38p per share, making this deal worth £1.044bn.
This deal, however, was rejected by C&WW’s largest shareholder, Orbis, within hours, as the price was not high enough, despite the 38p per share offer representing a 92% premium to the level of C&WW’s share price before the bid interest emerged in February. A spokesperson for Orbis said:
‘Although we believe the C&WW management team has handled the bid process responsibly, we have declined to give an irrevocable undertaking or letter of intent to the support the transaction.’
However, with the only other interested party, Tata Communications withdrawing, Vodafone was the only remaining bidder. As such, many suggest that this deal is a good one for the struggling business, despite Orbis’ claim that it under-values the business.
Adding a UK fixed-line cable to Vodafone’s business will increase its capacity, which is much needed at this moment in time with the added demand for mobile data from increased Smartphone usage. Cost savings are also expected from this merger, as the company will no longer have to pay to other companies to lease its fixed-line capacity.
The bid from Vodafone did help C&WW’s trading performance, which had been worsening for some time and so some shareholders will be glad of the bid. Its shares were up following this deal and it went to the top of the FTSE250. Vodafone will also benefit, as this merger would make it the second largest combined fixed and mobile line operator in the UK.
The trends of these two companies in recent years have been very much in contrast. C&WW had been the larger of the two firms up until 1999, yet the price Vodafone would now pay for the company represents a mere 1% of its current market value. The following articles consider this merger.
