How much value do you place on that wonderful long weekend that a Bank holiday brings? The extra lie in; the ensuing 4 day week; the time you spend with your family. Some would say it’s invaluable – you can’t put a price on it. But those some people would not be economists! Each Bank holiday is worth about £2bn – at least that’s how much it costs the economy.
According to the Centre for Economics and Business Research, if the UK got rid of its Bank holidays, GDP would increase by approximately £18bn.
Some businesses will do well out the Bank holidays, but according to the research, the sectors of the economy that suffer are far greater, causing losses in productivity and hence in GDP. Indeed, the extra Bank Holiday we had last year for the Royal Wedding is thought to have been part of the cause for the slow down in growth to 0.1% during the second quarter of 2011.
Based on this data, there are unsurprisingly concerns that the extra Bank holiday this year for the Queen’s Diamond Jubilee could also cost the economy. Not particularly good news, considering how vulnerable the economy currently is. Although the Queen’s Diamond Jubilee will undoubtedly generate huge amounts of spending, it is thought that this will be more than offset by the sectors that are expected to lose out because of the loss in working hours and hence productivity.
Given the cost of Bank holidays to the economy, the CEBR says that they should be spread more evenly throughout the year. Is this the solution &ndash if one is needed – or should they be abolished altogether! The following articles consider the issue.

- Which sectors will generally benefit from Bank holidays?
- Which areas of the economy are likely to contribute towards lost output because of a Bank holiday?
- Why does CEBR suggest that spreading out Bank holidays more evenly across the year would be less costly for economic growth?
- How can the value of lost output during one day be calculated?
- Does a Bank holiday add to somebody’s well-being? How could we measure this?
Next year a government agreement with insurance companies is set to end. This agreement requires insurance companies to provide cover for homes at a high risk of flooding.
However, in June 2013, this agreement will no longer be in place and this has led to mounting concerns that it will leave thousands of home-owners with the inability either to find or afford home insurance.
The key thing with insurance is that in order for it to be provided privately, certain conditions must hold. The probability of the event occurring must be less than 1 – insurance companies will not insure against certainty. The probability of the event must be known on aggregate to allow insurance companies to calculate premiums. Probabilities must be independent – if one person makes a claim, it should not increase the likelihood of others making claims.
Finally, there should be no adverse selection or moral hazard, both of which derive from asymmetric information. The former occurs where the person taking out the insurance can hide information from the company (i.e. that they are a bad risk) and the latter occurs when the person taking out insurance changes their behaviour once they are insured. Only if these conditions hold or there are easy solutions will the private market provide insurance.
On the demand-side, consumers must be willing to pay for insurance, which provides them with protection against certain contingencies: in this case against the cost of flood damage. Given the choice, rational consumers will only take out an insurance policy if they believe that the value they get from the certainty of knowing they are covered exceeds the cost of paying the insurance premium. However, if the private market fails to offer insurance, because of failures on the supply-side, there will be major gaps in coverage.
Furthermore, even if insurance policies are offered to those at most risk of flooding, the premiums charged by the insurance companies must be high enough to cover the cost of flood damage. For some homeowners, these premiums may be unaffordable, again leading to gaps in coverage.
In light of the agreement coming to an end next year, there is pressure on the government firstly to ensure that insurance cover is available to everyone at affordable prices and secondly to continue to build up flood defences in the most affected areas. Not an easy task given the budget cuts. The following articles provide some of the coverage of the problems of insuring against flood damage.

ABI refuses to renew statement of principles for flood insurance Insurance Age, Emmanuel Kenning (31/1/12)
Questions
- Consider the market for insurance against flood damage. Are risks less than one? Explain your answer
- Explain whether or not the risk of flooding is independent.
- Are the problems of moral hazard and adverse selection relevant in the case of home insurance against flood damage?
- If ABI doesn’t put in place another agreement to provide insurance to homeowners at most risk of flooding, what could be the adverse economic consequences?
- Is there an argument for the government stepping in to provide insurance itself?
- Explain why insurance premiums are so much higher for those at most risk of flooding. Is it equitable?
Most people are risk-averse: we like certainty and are generally prepared to pay a premium for it. The reason is that certainty gives us positive marginal utility and so as long as the price of insurance (which gives us certainty) is less than the price we place on certainty, we will be willing to pay a positive premium. By having insurance, we know that should the unexpected happen, someone else will cover the risk. As long as there are some risk-averse people, there will always be a demand for insurance.
However, will private companies will be willing to supply it? For private market insurance to be efficient, 5 conditions must hold:
1. Probabilities must be independent
2. Probabilities must be less than one
3. Probabilities must be known or estimable
4. There must be no adverse selection
5. There must be no moral hazard
If these conditions hold or if there are simple solutions, then insurance companies will be willing and able to provide insurance at a price consumers are willing to pay.
There are many markets where we take out insurance – some of them where insurance is compulsory, including home and car insurance. However, one type of insurance that is not compulsory is that for cyclists. No insurance is needed to cycle on the road, but with cycle use increasing and with that the number of accidents involving cyclists also increasing, the calls for cyclists to have some type of insurance is growing. If they are hit by someone without insurance and perhaps suffer from a loss of income; or if they cause vehicle damage, they will receive no compensation. However, whilst the risk of accident is increasing for cyclists, they are still statistically less likely to cause an accident than motorists. Perhaps a mere £30 or £40 per year for a policy is a price worth paying to give cyclists certainty. At least, this is what the Association of British Insurers (ABI) is claiming – hardly surprising when their members made a combined loss of £1.2 billion!

Questions
- With each of the above conditions required for private insurance to be possible, explain why each must hold.
- What do we mean by no moral hazard and no adverse selection? Why would their existence prevent a private company from providing insurance?
- Using the concept of marginal utility theory, explain why there is a positive demand insurance.
- What might explain why cyclists are less likely to take out insurance given your answer to the above question?
- Do you think cyclist insurance should be compulsory? If governments are trying to encourage more sustainable transport policy, do you think this is a viable policy?
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!

Economics studies scarcity and the allocation of resources. Central to societies’ economic objectives is the reduction in scarcity and central to that is economic growth. Certainly, economic growth is a major objective of all governments. They know that they will be judged by their record on economic growth.
But what do we mean by economic growth? The normal measure is growth in GDP. But does GDP measure how much a society benefits? Many people argue that GDP is a poor proxy for social benefit and that a new method of establishing the level of human well-being and happiness is necessary.
And it’s not just at macro level. As we saw in a previous news article, A new felicific calculus? happiness and unhappiness are central to economists’ analysis of consumer behaviour. If we define ‘utility’ as perceived happiness, standard consumer theory assumes that rational people will seek to maximise the excess of happiness over the costs of achieving it: i.e. will seek to maximise consumer surplus.
There have been three recent developments in the measurement of happiness. ‘Understanding Society’ is a £48.9m government-funded UK study following 40,000 households and is run by the Institute of Social and Economic Research (ISER) at the University of Essex. It has just published its first findings (see link below).
The second development is the work by the ONS on developing new measures of national well-being and includes a questionnaire asking about the things that matter to people and which should be included in a measure or measures of national well-being.
The third development will be an addition of five new questions to the Integrated Household Survey:
• Overall, how satisfied are you with your life nowadays?
• Overall, how happy did you feel yesterday?
• Overall, how anxious did you feel yesterday?
• Overall, to what extent do you feel the things you do in your life are worthwhile?
But after all this, will we be any closer to getting a correct measure of human well-being? Will the results of such investigations help governments devise policy? Will the government be closer to measuring the costs and benefits of any policy decisions?
