With the world economy in recession, major exporting countries are suffering more than many, especially exporters of high-quality manufactured products, many of which have a high income elasticity of demand. Germany, the world’s largest exporter, has been particularly hard hit. In the year to April 2009, the value of German exports fell by 28.7 per cent. The following articles look at the data and some of the explanations.

Questions
- Why have German exports fallen considerably more than German GDP? How can the accelerator theory help to explain the fall in German exports?
- If economic sentiment recovers in Germany, how will this affect (a) aggregate demand; (b) imports; (c) exports?
- Find out what has happened to the euro exchange rate index and assess whether movements in the euro have contributed to Germany’s export performance (see for example the Bank of England Statistical Interactive Database).
The following link is to a video charting the growth of China and the UK over the past 200 years and projecting forward to 2014. The video is from Gapminder, a site that allows you to compare countries’ performance in terms of a large range of economic and social indicators.
The introduction to this video states, “200 years ago, United Kingdom was a leading nation of the world – both in regard to health and economy. In this video, Hans Rosling details UK’s 200-year journey, to present time, and also shows that China, in the coming five years, will narrow the gap to UK faster than ever.”
Crisis narrows China–UK gap Hans Rosling, Gapminder (2/6/09)
Questions
- Why has the gap in GDP per head narrowed between the China and the UK?
- Why is the gap likely to narrow further over the next five years?
- Identify the factors that will determine how much the gap is likely to narrow in this period.
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!

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

- 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?
