Should cyclists have insurance?

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!

Imprisoning prisoners with wage cuts

Through new legislation, the Ministry of Justice is aiming to make ‘offenders … take personal responsibility for their crimes’. The idea is to cut the wages of prisoners who work in communities, with the objective of raising £1m a year for victim support services. Any prisoner earning above £20 a week after tax, national insurance, child support payments etc, will face a 40% deduction in their pay. The money raised will be used to ‘repair the damage done by crime’ and begin to remove the burden from the general taxpayer. Critics, however, argue that this legislation will create a disincentive effect and discourage prisoners to work in the community before their release. It may also create additional bureaucracy for the external firms that employ them and at the end of the day may not even affect most prisoners, as many receive earnings, after all deductions, below £20 and so would not be liable. The following articles consider this policy.

Prisoners’ wages to help crime victims BBC News (26/9/11)
Prisoners to pay victims of crime The Press Association (26/9/11)
Victims handed £1m as prisoners suffer wage cut Independent, Nigel Morris (26/9/11)

Questions

  1. To what extent do you think the above policy is (a) equitable and (b) efficient?
  2. What might be the adverse effects of such legislation, from the point of view of both prisoners and the firms that employ them?
  3. What are the income and substitution effects in the context of a worker’s decision to work more or less hours?
  4. Using indifference analysis, explain how a fall in the prisoners’ net pay (due to this latest deduction) might have an impact on their desire to work more or less.
  5. Using your analysis from the previous question, explain the importance of the income and substitution effects.

Is a nudging enough?

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!

Happiness economics

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?

  6. Should other countries follow Bhutan’s example and use a ‘groass national happiness index’ to drive economic and social policy?
  7. If human well-being could be accurately measured, should that be the sole driver of economic and social policy?
  8. Do people’s spending patterns give a good indication of the things that give them happiness?

The economics of love, marriage and dirty dishes

Economics is about choice – and choices occur in all parts of our lives. One area is personal relationships. Are we making the best of our relationships with family, friends and sexual partners? Increasingly economists are examining human behaviour in such contexts and asking what factors determine our decisions and whether such decisions are rational.

A recent book looks at the economics of marriage and goes under the title of ‘Spousonomics‘. Its authors, Paula Szuchman and Jenny Anderson, use economics “to master love, marriage and dirty dishes”. As they say:

Every marriage is its own little economy, a business of two with a finite number of resources that need to be allocated efficiently.

They look at ways in which such resources can be allocated efficiently. They also look at apparently irrational behaviour and seek to explain it in terms of various ‘failures’ (akin to market failures). They also examine how these failures can be rectified to improve relationships.

So is this economics stepping on the toes of relationship counsellors and psychologists? Or is this the legitimate domain of economists seeking to understand how to optimise in the context of scarce resources – including time and patience?
