With a mounting crisis in the eurozone, heads of government met in an emergency meeting in Brussels on 21 July.

The task was a massive one: how to tackle Greece’s growing debt crisis and stave off default; how to protect other highly indebted countries which have already had to seek emergency bailouts, namely Ireland and Portugal, from falling market confidence and thus rising interest rates, thereby making their debts harder to service; how to prevent speculative pressures extending like a contagion to other highly indebted countries, such as Spain and Italy; how to prevent speculation against the euro and even to prevent its break-up; how to reduce the size of budget deficits at a time of low growth without jeopardising that growth. A problem is that Greece has already adopted the required austerity measures for it to receive a second bailout from the EU agreed at the end of June, and yet its debt burden is likely to rise as growth remains negative.

Eurozone leaders recognised that the stakes were high. Failure could see contagion spread, interest rates soar and perhaps one or more countries leaving the euro. No agreement was not an option. As it turned out, the agreement was more comprehensive than most commentators had expected. Markets reacted positively. Stock markets in Europe and around the world rose and the euro strengthened.

So what was the agreement? Has it solved the Greek and eurozone crises? Will it prevent contagion? Or has it merely put the problem on hold for the time being? Will more fundamental measures have to be put in place, such as much fuller fiscal union, if the eurozone is to function as an effective single currency area? The following is a selection of the hundreds of articles worldwide that have reported on the summit and the agreement.

In 2009, Nudge: Improving Decisions about Health, Wealth, and Happiness was published. This book by Richard Thaler and Cass R. Sunstein examines how people are influenced to make decisions or change behaviour.

According to Thaler and Sunstein, people can be ‘nudged’ to change their behaviour. For example, healthy food can be placed in a prominent position in a supermarket or healthy snacks at the checkout. Often it is the junk foods that are displayed prominently and unhealthy, but tasty, snacks are found by the checkout. If fashion houses ceased to use ultra thin models, it could reduce the incentive for many girls to under-eat. If kids at school are given stars or smiley faces for turning off lights or picking up litter, they might be more inclined to do so.

The UK government has been investigating the use of ‘nudges’ as a way of changing behaviour, and the House of Lords Science and Technology Committee has been considering the question. It has just published its report, Behaviour Change. The summary of the report states that:

The currently influential book Nudge by Richard Thaler and Cass Sunstein advocates a range of non-regulatory interventions that seek to influence behaviour by altering the context or environment in which people choose, and seek to influence behaviour in ways which people often do not notice. This approach differs from more traditional government attempts to change behaviour, which have either used regulatory interventions or relied on overt persuasion.

The current Government have taken a considerable interest in the use of “nudge interventions”. Consequently, one aim of this inquiry was to assess the evidence-base for the effectiveness of “nudges”. However, we also examined evidence for the effectiveness of other types of policy intervention, regulatory and non-regulatory, and asked whether the Government make good use of the full range of available evidence when seeking to change behaviour.

The report finds that nudges

… used in isolation will often not be effective in changing the behaviour of the population. Instead, a whole range of measures – including some regulatory measures – will be needed to change behaviour in a way that will make a real difference to society’s biggest problems.

So is there, nevertheless, a role for nudges in changing behaviour – albeit alongside other measures? Read the report and the articles below to find out!

Economic assessment of real-world issues relies heavily on data. It is the same with economic policy recommendations. Both public- and private-sector organisations gather data, which are then used for analysis, often presented in a report. These reports are then often used as the basis for policy, whether by the government, local authorities or the private sector. Sometimes the data are those collected by national statistical agencies, such as the Office for National Statistics (ONS) in the UK; sometimes they are collected by private agencies; sometimes by individual researchers.

Clearly the analysis and the suitability of any policy recommendations depend on the quality of the data. But how much can we rely on the data? A problem is that people have an interest in gathering and/or selecting data that support their opinions. As a result, the data used for analysis and policy recommendations may be unreliable and incomplete.

This is not to say that the data collected by reputable agencies such as the ONS are wrong. Rather, it is the selective use of them that can be highly misleading. Sometimes, however, the data that some agencies produce may indeed be unreliable, with too small or unrepresentative samples. If they rely on surveys, the survey questions may be poorly framed or lead the respondent into giving a particular answer.

Newspapers make use of data and reports all the time to make a particular case – a case in line with the newspaper’s political stance. The lesson for economic students is that we need to be alert all the time as to just how reliable data are; and to whether the conclusions drawn from them are correct.

The following two articles by Ben Goldacre, from the Guardian’s Bad Science series, look at the misuse of data. The first looks at the case of the Health Service; the second at the possibility of savings by local government in their procurement activities.

Questions

  1. According to the first article above, how much newspaper reporting based on the use of data is unreliable?
  2. What are the reasons for the unreliability of newspaper reporting?
  3. For what reasons might the ONS and other reputable agencies periodically have to amend time series data?
  4. “Council incompetence ‘costs every household £452 a year'”. Critically examine this claim by the Daily Mail.
  5. Why may Opera Solutions be seen as not wholly independent in reporting the possibilities of cost savings by local government?
  6. In the absence of reliable data, can any economic policy conclusions be drawn from economic models? Explain.

Taxes are a key element in redistributive policies: taxes on the rich can be spent on benefits to the poor. The more progressive the taxes (i.e. the more steeply they rise with rising incomes), the bigger will be the redistributive effect and hence the more equal will post-tax incomes be.

But high and steeply progressive taxes can act as a disincentive to work longer, or to go for promotion or to move to a better paid job. High corporate taxes and income taxes can act as disincentive to inward investment and may encourage a ‘brain drain’ and capital flight with people and capital leaving the country for lower tax regimes abroad.

Raising taxes has two effects. First there is the substitution effect: people may work less and substitute it with leisure – after all, work is now less rewarding. People may also substitute working abroad for working at home. But the second effect works in the opposite direction. This is the income effect. As taxes are raised and people’s take-home pay is thereby reduced, they may feel the need to work longer hours or try harder for promotion in order to make up the lost income and maintain their living standards. Thus the effect of higher taxes is not clear-cut. It is an empirical question of which of the two effects is the stronger.

One important determinant of the effects of different tax rates is their relative position compared with other countries. Another is the international mobility of labour and capital. The greater the mobility, the greater the elasticity of supply with respect to changes in tax rates.

The following report and articles look at relative tax rates between different countries and the effects on output and factor movements

Questions

  1. Why may relative income tax rates between countries give only a partial picture of the international competitiveness of these countries? What else would need to be taken into account?
  2. Does making taxes more steeply progressive necessarily act as a disincentive to output? Explain.
  3. What factors are likely to determine the relative size of the income and substitution effects of tax changes?
  4. How progressive are income taxes in the UK compared with other countries? Give examples.
  5. What externalities (positive and negative) might result from steeply progressive income tax rates?
  6. What determines the international elasticity of supply of labour?
  7. What is the Laffer curve? How will the shape of the Laffer curve be affected by the international mobility of labour and international tax rates?

The government is sticking to its deficit reduction plan. But with worries about a lack of economic recovery, or even a double dip recession, some economists are calling for a Plan B. They back up their arguments by referring to the lack of consumer confidence, falling real incomes and rising commodity prices. Without a slowing down in cuts and tax rises, the lack of aggregate demand, they claim, will prevent a recovery.

The government maintains that sticking to the cuts and tax rises helps maintain international confidence and thereby helps to keep interest rates low. Also, it argues, if the economy does slow down, then automatic stabilisers will come into play. Finally, even though fiscal policy is tight, monetary policy is relatively loose, with historically low interest rates.

But will there be enough confidence to sustain a recovery? Economists are clearly divided. But at least the IMF seems to think so. In its latest assessment of the UK economy, although it has cut the growth forecast for 2011 from 2% to 1.5%, that is still a positive figure and thus represents a recovery, albeit a rather fragile one.
