Should economists have foreseen the credit crunch? A few were warning of an overheated world economy with excessive credit and risk taking. Most economists prior to 2007/8, however, were predicting a continuation of steady economic growth. Inflation targeting, fiscal rules and increasingly flexible markets were the ingredients of this continuing prosperity. And then the crash happened!
So why did so few people see the downturn coming? Were the models used by economists fundamentally flawed, or was it simply a question of poor assumptions or poor data? Do we need a new way of modelling the economy, or is it simply a question of updating theories from the past? Should, for example, models become much more Keynesian? Should we abandon the new classical approach of assuming that markets are essentially good at pricing in risk and that herd behaviour will not be seriously destabilising?
The following podcast looks at these issues. “Aditya Chakrabortty’s joined in the studio by the Guardian’s economics editor Larry Elliott, as well as Roger Bootle, the managing director of Capital Economics, and political economist and John Maynard Keynes biographer Robert Skidelsky. Also in the podcast, we hear from Nobel prize-winning economist, Elinor Ostrom, Freakonomics author Steven Levitt, and UN advisor and developmental economist Daniel Gay.”

Questions
- Why did most economists fail to predict the credit crunch and subsequent recession? Was it a problem with the models that were used or the data that was put into these models, or both?
- What was the Washington consensus? To what extent did this consensus contribute to the current recession?
- What is meant by systemic risk? How does this influence the usefulness of ‘micro’ financial models?
- What particular market failures were responsible for the credit crunch?
- What is meant by ‘rational behaviour’? Is it reasonable to assume that people are rational?
- Is macroeconomics too theoretical or too mathematical (or both)? If you think it is, how can macroeconomics be reformed to improve its explanatory and predictive power?
- Does a ‘really good economist’ need to have a good grounding in a range of social sciences and in economic history?
The National Institute for Health and Clinical Excellence (NICE) is the independent agency in the UK charged, amongst other things, with assessing the cost-effectiveness of new drugs. In a report published on 19 November 2009, NICE found that the drug sorafenib, branded as Nexavar by its manufacturer, the German pharmaceutical company, Bayer AG, was not cost-effective. The drug can extend the life of terminally ill patients with liver cancer. However, it is very expensive, costing about £3000 per month per patient.
The NICE press release (see link below) quotes Andrew Dillon, the Chief Executive of NICE, as saying: “We were disappointed not to have been able to recommend the use of sorafenib, but after carefully considering all the evidence, including the proposed ‘patient access scheme’ in which the manufacturer offered to provide every fourth pack free, sorafenib does not provide enough benefit to patients to justify its high cost.”
Not surprisingly people suffering from liver cancer, and also various patient groups, were highly critical of the decision. But with a limited budget for the National Health Service and the increasing pressure to save costs in order to reduce the public-sector debt, many difficult choices like this have to be made.
What NICE attempts to do is a cost–benefit analysis of new drugs. Whilst costs can be difficult to measure, especially over the longer term, the benefits are much more problematic as they have to take into account the effects on the quality of people’s lives – something that will vary enormously from one patient to another. And then there are the effects on family and friends and on the economy. The measure used in the NHS and elswhere is the QALY – ‘quality-adjusted life year’. In paragraph 4.8 of the full NICE report (see link below), it was noted that
“the base-case ICER [incremental cost-effectiveness ratio] presented by the manufacturer was originally £64,800 per QALY gained and when the patient access scheme was included [where every fourth pack is supplied free to the NHS by Bayer] this went down to £51,900 per QALY gained. Both ICERs were substantially higher than those normally considered to be an acceptable use of NHS resources.”

Questions
- What makes the choice of whether to provide a particular drug to a pateint an ‘economic’ one?
- Imagine you were a person suffering from liver cancer. What evidence would you wish to bring to the government to persuade it to ignore NICE’s recommendation?
- Is the use of QALYs the best means of assessing the benefits of a drug? Explain.
- What are the arguments for and againist the NHS providing expensive drugs free to people on low incomes but charging a price well above the current prescription fee to those who could afford to pay? If such as scheme were introduced, on what basis should such a price be determined and should it be on a sliding scale according to people’s income and/or wealth?
The traditional macroeconomic issues are well-known: unemployment, inflation, economic growth and the balance of payments. However, the environment, and specifically climate change, have become increasingly important objectives for the global economy. Over recent months, many countries have announced new policies and measures to tackle climate change.
The costs of not tackling climate change are well-documented, but what about the costs of actually tackling it? Why is a changing climate receiving such attention and what are the economics behind this problem? The articles below consider this important issue.

- Apart from imposing limits on emissions, what other interventionist policies could be used? What are the advantages and disadvantages of each of them?
- According to the EU, the cost of tackling climate change is very high. So, why are we doing it? See if you can carry out a cost-benefit analysis!
- Why is climate change presenting a problem for insurance companies? Can it be overcome?
- Why is finance such an issue between developed and developing countries in relation to tackling climate change?
- What is the likely impact of climate changing policies on the labour market? Will we be able to adapt in the current economic crisis?
Even in the current gloomy economic climate, there is something else that has grabbed media attention – the outbreak of swine flu. This is of particular concern, given the WHO’s announcement that we are in an H1N1 flu pandemic. The symptoms and health risks have been widely broadcast, but it is not just this that governments are concerned about. The economies of some countries, in particular Mexico, have been suffering. ‘Swine flu has dealt a major blow to Mexico’s already battered economy’. Many countries have issued advice to businesses on dealing with a potential pandemic and some countries are facing trade restrictions. It’s important to consider the economic consequences of this outbreak in a time of global recession. How will some of the worst hit industries cope and what are the costs that firms could face if the situation gets worse? The following articles explore the issues.

Questions
- Which industries are the most affected by the outbreak of swine flu?
- What are some of the costs that businesses will face following the WHO’s announcement that we are in a flu pandemic?
- Some of the articles talk about possible trade restrictions. What are the arguments (a) for (b) against protectionist measures in these circumstances?
- How will this flu pandemic add to the global crisis we are currently facing? What will happen to share prices, to tourism, to people’s expectations?
- Do you think that firms have a social responsibility to deal with this pandemic?
- Will there be additional health costs and who should bear them? What do you think will be the impact on the NHS, given its method of provision and finance?
- Do you think that this pandemic will affect the global economy’s ability to recover from this recession?
Forecasting the future state of economies is difficult at the best of times. Forecasters frequently get it wrong. To see this, just look at forecasts for the current point in time made two or three years ago – or even six months ago, given the current dire circumstances. They were often way-off mark.
But why are forecasts often so inaccurate? The problem is that in the short run the state of the economy depends on the level of aggregate demand; and that, in turn, depends crucially on confidence – both of consumers and business. But confidence is a ‘will-o’-the-wisp’ thing. Confidence can evaporate with bad news, making the situation much worse. Likewise, good news can lead to rapidly growing optimism, which in turn stimulates consumption, investment and growth. Humans are fickle creatures – and the media do not help here, playing on fears or hyping-up good news.
The following articles look at forecasts made in April 2009, when economies around the world were deep in recession. Was this recession the start of something much worse? Or were economies soon to bounce back, taking up the slack created by the recession? Forecasters were being sorely tested. It will be interesting to see in a year’s time just how accurate, or inaccurate, they were.

- Why do forecasters differ so markedly from each other?
- Other than an unexpected rise or fall in confidence, what else could make forecasts turn out to be wrong?
- To what extent is economic forecasting similar to and different from weather forecasting?
