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

  1. Describe what is meant by ‘animal spirits’ and their effects on human behaviour.
  2. Why may animal spirits make economies less stable?
  3. How may animal spirits help to explain exchange rate overshooting?
  4. 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

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

In a recession, the government’s budget will go into cyclical deficit as tax revenue falls and government spending on unemployment and other benefits rises. Provided the deficit is purely cyclical, it can be seen as desirable since it acts as an automatic fiscal stabiliser, boosting aggregate demand and helping to pull the economy out of recession. Once the economy returns to potential national income (i.e. a zero output gap), the deficit would disappear. At potential national income (Yp), government expenditure (including benefits) will equal tax revenue. The budget is in balance.

Again, provided that the deficit is only cyclical, discretionary expansionary fiscal policy that further deepens the deficit will not be a problem for public finances in the future. Once the economy pulls out of recession, the discretionary policy can be relaxed and the higher national income will eliminate the cyclical deficit.

But the problem the Chancellor of the Exchequer faced in the Budget (on 22/4/09) was not just one of tackling the recession. The UK economy has seen a massive growth in the structural deficit. His forecast is for the total deficit to be £175bn in 2009. But, according to calculations by the Institute for Fiscal Studies, even when the recession is over and the output gap has been closed, there will still be an annual deficit of around £140bn. This is not cyclical; it’s structural.

So why is there this huge structural deficit? And what is the solution? Will the solution slow down recovery? The following articles look at the issues.

Questions

  1. Explain the terms ‘cyclical deficit’ and ‘structural deficit’.
  2. Draw a diagram showing how government expenditure (including benefits) and tax revenue vary with national income. The diagram should show the sitation with no structural deficit: i.e. the two lines should cross at potential national income. Illustrate (a) a cyclical deficit where actual national income is below potential national income (a negative output gap) and (b) a cyclical surplus where actual national income is above potential income (a positive output gap).
  3. Now, on the same diagram, shift the two lines to illustrate a situation of structural deficit.
  4. Consider whether the government should attempt to increase or reduce the budget deficit at a time of recession.
  5. Why has the structural deficit become so severe over the past year?
  6. How quickly should the government set about tackling the structural deficit?

In an earlier news item we saw that the global recession has hit the demand for organic produce. The same is not true for Fairtrade products as a global survey published on 17/4/09 shows (see). Awareness of Fairtrade products continues to grow as do sales. The articles below look at the findings of this survey and at the explanations behind it.

Questions

  1. Consider the reasons why Fairtrade sales have increased while sales of organic produce have declined.
  2. Does purchasing Fairtrade products mean that consumers are not seeking to maximise their consumer surplus?
  3. What economic challenges face Fairtrade producers? How should governments help the Fairtrade movement?
  4. Is the liberalisation of trade in the interests of Fairtrade producers?

In a major break from the policy of the Bush administration, President Obama has announced that the US government will regulate greenhouse gas emissions. The US Environmental Protection Agency has found that CO2 emissions pose a ‘threat to public health and welfare’. This finding allows regulation to be imposed.

At the end of March the Democrats in the House of Representatives released a draft climate change Bill. Central to this would be a system of tradable permits. ‘Under this program, covered entities must have tradable federal allowances for each ton of pollution emitted into the atmosphere.’ (See 4th article below.)

Questions

  1. To what extent is the EPA ruling compatible with the bill proposed by the Democrats?
  2. Is a ‘cap-and-trade’ system (i.e. tradable permits) the best way of dealing with climate change?
  3. What lessons can the USA draw from the European Emissions Trading Scheme in designing its own tradable permits scheme?
