The following articles look at a recently published book by George Akerlof of the University of California, Berkeley, and Robert Shiller of Yale. They examine the role of what Keynes called ‘animal spirits’ and is the title of the book.
The motivation to make economic decisions (to buy, to sell, to invest, etc) may not be ‘rational’ in the sense of carefully weighing up marginal costs and marginal benefits. Rather it can be one of over-optimism in good times or over-pessimism in bad times. Just as individuals have ‘mood swings’, so there can be collective mood swings too. After all, confidence, or lack of it, is contagious. This motivation that drives people to action is what is meant by animal spirits.
But are animal spirits a blessing to be nurtured or a curse to be reined in? Should governments seek to constrain them?

Questions
- Describe what is meant by ‘animal spirits’ and their effects on human behaviour.
- Why may animal spirits make economies less stable?
- How may animal spirits help to explain exchange rate overshooting?
- Discuss whether governments should seek to constrain animal spirits and make people more ‘rational’? Also consider what methods governments could/should use to do this?
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.

Questions
- 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?
Every six months the OECD publishes its Economic Outlook. This gives annual (and some quarterly) macroeconomic data for each of the 30 OECD countries, for all 30 countries together and for the eurozone. There are 63 tables covering most of the major macroeconomic indicators, most going back 13 years with forecasts for the next two years. OECD Economic Outlook is normally published in June and December.
Similarly, every six months the European Commission’s Economic and Financial Affairs Directorate publishes its European Economy Statistical Annex. This gives annual data for 76 macroeconomic variables for each of the EU countries, plus the USA and Japan. Most of the tables go back to 1970 and forecast ahead for two years. There is also a separate publication, Economic Forecasts. The statistical appendix to this publication has 62 tables, again covering a range of macroeconomic data. The tables go back to 1992 and again forecast ahead for two years. There is a lot of useful commentary about the individual economies of the EU and other major economies, such as the USA, Japan, China and Russia. Both publications normally appear in May and November.
Another organisation to publish 6-monthly forecasts is the International Monetary Fund. The Statistical Appendix of the Word Economic Outlook (after clicking on this, go to link on right), normally published in April and October, gives macroeconomic data for most economies and regions of the world. Forecasts are made ahead for two years and for five years.
The state of the world economy was so severe in early 2009 and was deteriorating so rapidly that earlier forecasts proved far too optimistic. In early 2009, all three organisations published interim forecasts – the European Commission and the IMF in January and the OECD at the end of March. They painted a much bleaker picture than the forecasts published at the end of 2008. What will the next set of forecasts look like? Will they be even bleaker?
The following links take you to these interim forecasts and to articles commenting on them.

Questions
- Compare the forecasts for GDP growth, unemployment, inflation and output gaps for some of the major economies made by the OECD at the end of March with those made by the European Commission and the IMF in January and with those made by all three organisations in the autumn of 2008. Why, do you think, are there such large divergences in the forecasts?
- For what reasons might the OECD March forecasts turn out to be (a) much too pessimistic; (b) much too optimistic?
- In the light of the forecasts, should countries adopt further strongly expansionary fiscal policies – something rejected at the G20 summit in Early April (see news item Saving the world)?
The term hyperinflation is almost an understatement when it comes to describing the level of inflation in Zimbabwe. In July 2008, inflation was estimated to be 231 million per cent. In January 2009, two estimates were made: one of 5 sextillion per cent (5 and 21 zeros); the other of 6.5 quindecillion novemdecillion per cent (65 and 107 zeros). These figures are simply mind-boggling for most people living in low-inflation economies.
Commentators say that prices can double in a single day and this can render banknotes useless very quickly. In fact, local banknotes are scarcely used as people turn to overseas currencies that offer more stability. Recognising this, in late January 2009 the government officially allowed foreign currencies to be used in Zimbabwe as well as the Zimbabwe dollar.
In an attempt to stabilise the currency the Zimbabwean central bank on more than one occasion has tried dropping several zeros from the currency. But this has had little effect and in January 2009 a new series of banknotes was issued, including a Z$100 trillion note. This is unlikely to be the last issue though, but what comes after a trillion?

Questions
- Define the term hyperinflation.
- Analyse the main causes of hyperinflation.
- Discuss policies that the Zimbabwean government could adopt to try to reduce the level of inflation in the economy.
- Assess the impact of hyperinflation on the other major macro-economic targets.
- Research another instance of hyperinflation and write a brief summary of the cause(s) and the solution(s). You may find the Wikipedia entry on hyperinflation a good starting point.
Given all the attention that the recession has had for months in the media, it may be surprising to find out that in fact Britain only went into recession officially today (January 23rd 2009). This is because, as economists, we have a more precise definition of recession than much of the media. A recession is when there is two successive quarters of negative economic growth. Figures released by the ONS today, show that this is finally the case. The links below give a flavour of the media attention dedicated to this announcement.
