A key cause of the financial crisis is arguably Maths. Many of the innovations in the finance industry were driven by Maths and a desire to generate higher returns from the money available. The BBC programme, More or Less, looks at the Maths of the credit crunch and considers the extent to which the misuse of mathematical principles may have contributed to the crisis. The links below look at the issues raised by the programme and also give access to the archived audio from the programme.

Economists never like to use simple words when there are more complex ones available! So, the new term for printing money is ‘quantitative easing’. This refers to deliberate increases in the money supply aimed at preventing deflation. The real concern is whether quantitative easing will stoke up inflationary pressures for the future – the balance between inflation and deflation is a fine line to tread. Quantitative easing becomes necessary when there is danger of deflation and interest rates have already been cut as far as is possible.
Another problem, in the short term, is that an increase in the monetary base may have little effect on broader money (M4 in the UK) if people do not want to borrow and thus credit creation is limited.
The articles below all look at various different aspects of quantitative easing.

Questions
- Define the term ‘quantitative easing’.
- Explain the mechanism by which the monetary authorities can implement a policy of quantitative easing.
- Discuss the relative effectiveness of cuts in interest rates and quantitative easing to boost aggregate demand in a recession.
- Analyse the impact on an economy of a prolonged period of deflation.
Many commentators (and politicians) have suggested that the most painless route out of the recession is for us all to shop until we drop. If we can prevent consumer spending from falling too far then this may help maintain oonsumer confidence and therefore aggregate demand. So, is it our patriotic duty to shop? Should we all be out there helping in our own small way to prevent recession, or will more shopping just land us even further in debt and therefore make us worse off? The articles linked to below look at various aspects of the ‘shopping debate’ and consider whether retail therapy is also economic therapy.

Should shopping be a patriotic duty? BBC News Online (19/12/08)
Questions
- How could the need both to reduce debt and to maintain aggregate demand be reconciled?
- Discuss the extent to which an increase in consumer expenditure is (a) a necessary and (b) a sufficient condition for a recovery of the economy?
- To what extent will long-term aggregate supply depend on the maintenance of aggregate demand?
- If shopping is your patriotic duty, what types of shopping would be best for the country?
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.

Sir Alan Walters, one of Mrs Thatcher’s key economic advisers, has died at the age of 82. Though he always tried to shun media attention, Sir Alan attracted a considerable amount of it when he clashed publicly with the then Chancellor, Nigel Lawson, over the Exchange Rate Mechanism (ERM). When faced with the choice from Nigel Lawson that either Alan Walters went or he did, Mrs Thatcher famously chose her adviser over her Chancellor. This lent Sir Alan a degree of infamy in economic circles and he is perhaps known best as one of the most influential monetarists of the period. Sir Alan was an early advocate of money supply targeting and always argued that the money supply should not be manipulated for political reasons. His advice was also key in the budget of 1981 which raised taxes in the middle of a recession, something that in this current recession would appear to be unthinkable.
