Category: Essential Economics for Business: Ch 05

Imagine putting together a dream team of economists to tackle the current recession. Who would you choose? Larry Elliott, the Guardian’s economics editor considers this game of ‘fantasy economics’ in the linked article below. In the process, he makes a number of criticisms of economists for saying little about what caused the current crisis and how such crises could be avoided in the future.

As students studying economics you might want to defend economists against this attack. After all, virtually every time you turn on the radio or television or open a paper, there are economists explaining what has happened and what should be done about it. So see if you can mount a defence against this attack – and maybe put together your own dream team of economists!

It’s a funny old game: where is the dream team of economists to tackle the slump? Guardian (1/6/09)

Profiles of many the economists referred to in Larry Elliott’s article can be found at the History of Economic Thought website. You can access this from the Sloman Hot Links tab above and then click on site C18.

Questions

  1. Explain why economies with deregulated financial markets are likely to experience macroeconomic instability (‘boom-bust cycles’).
  2. What are the benefits of studying perfectly competitive markets and general equilibrium theory?
  3. Write a brief defence of the use of mathematics in economics.
  4. Does experimental economics allow economists to take a ‘more nuanced and relevant approach’ to studying economic behaviour and devising appropriate policy?

The first linked article below is from the American business magazine Forbes. It looks at the economics of football (‘soccer’) signings and, in particular, that of Robinho by Manchester City. In September 2008 the club was bought by an Abu Dhabi investment fund, controlled by Sheikh Mansour bin Zayed Al Nahyan, for £210 million. But does the investment in new players make good business sense?

Also, what should determine whether a club sells a player? The third link below considers this issue. The link is to the Embedding Threshold Concepts (ETC) site at Staffordshire University. ETC was funded by the Higher Education Funding Council for England’s Fund for the Development of Teaching and Learning (FDTL). The site has a number of teaching and learning resources.

Questions

  1. Was it consistent with the goal of profit maximisation for Manchester City pay Real Madrid £32.5 million for Robinho? Was it consistent with the goal of profit maximisation for Real Madrid to sell him?
  2. If Real Madrid had decided to keep Robinho, how would you estimate the cost of doing so?
  3. What difficulties are there in developing Manchester City into a ‘global brand’?
  4. In what sense are the top Premier League clubs a ‘self-perpetuating oligopoly’?

Google is a classic example of the new ‘Internet economics’. The main service it provides – search – is completely free and yet it is an enornmously profitable company and growing fast. Much of what they provide in addition to their search service is also free: Google Docs, Google Maps and Google Scholar. So how do they do it? The first link below is an article considering this issue and the second link gives access to an archived version of In Business giving further detail. The programme is well worth listening to. A key part of the explanation for this new phenomenon relates to the low and falling costs of providing these internet services.

Energywatch, an industry watchdog, has argued in a recent report to MPs that Britain’s electricity and gas supply industry is a “comfortable oligopoly” that feels little need to innovate or compete. They have called for the sector to be subject to a Competition Commission investigation.

Shell have announced record profits of $27bn. This is the highest profit ever made by a European company and is only surpassed worldwide by the annual profits of another oil company ExxonMobil at $40bn. These high profits have led to calls for a windfall tax to be imposed on the oil companies and the articles below consider the likely impact of a tax of this nature.

Questions

1. Using diagrams as appropriate, show the impact on the equilibrium level of price and output of Shell of a windfall tax being imposed on their profits.
2. Discuss the extent to which the high level of profitability of oil companies is determined by the oil price.
3. Analyse whether a windfall tax is an economically efficient form of taxation. What alternatives could a government consider that might be more efficient?
