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?

You will probably have come across the concept of consumer sovereignty. In the mythical world of perfect markets, producers are at the beck and call of consumers. Firms that are not responsive to consumer demand go out of business. In other words, in order to survive they have to respond to any shifts in consumer demand. These in turn can be the result of changes in tastes, changes in income, changes in the prices of other goods, and so on.

Of course, the real world is not perfect, but it is still often assumed that consumers are powerful in influencing what firms sell and at what prices. Well, firms would much rather be in a position of manipulating consumer tastes and hence the huge amounts spent on advertising and marketing.

And it doesn’t end there. Firms use many pricing practices which, to put it mildly, try to confuse consumers or lure them into buying things by making them think they are getting something much cheaper than they really are. Take the case of airline tickets. Some budget airlines offer tickets at extremely low prices, such as 99p. But if you select such a flight, by the time you get to the final screen where taxes, charges, supplements, luggage, etc. are added, the price could exceed £100! And ask yourself this, when you buy something with 20% off, or when you buy ‘three for the price of two’ how rational was your decision? Did you really want the product? Was the offer really ‘genuine’?

The Office of Fair Trading has recently completed two investigations into pricing. As it stated 14 months ago when the investigations were launched:

The first, into online targeting of advertising and prices will cover behavioural advertising and customised pricing, where prices are individually tailored using information collected about a consumer’s internet use. It is expected that this study will be completed by spring 2010.

The second, into advertising of prices, will consider various pricing practices which may potentially mislead consumers. The study will look in particular, but not exclusively, at how these practices are used online.

The following articles look at some of the practices that firms use to drive sales – practices that deliberately attempt to manipulate the consumer. The assumption of ‘perfect knowledge’ by consumers may be a long way from the truth.

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. In fact, this analysis can be traced back to the work of the utilitarians, Jeremy Bentham and John Stuart Mill. Bentham reffered to it as hedonic or felicific calculus (see also and also).

Now, of course, whether people actually behave in this way is an empirical question: one that behavioural and experimental economists have been investigating over a number of years. Nevertheless, it remains central to neoclassical analysis of ‘rational behaviour’.

But if happiness is central to a large part of economic analysis, how is happiness to be measured? At a micro level, this has proved problematic as it is virtually impossible to have inter-personal comparisons of utility. As a result, consumer theory uses indifference analysis, characteristics analysis, revealed preference and other approaches to analyse consumer demand.

But what about at the macro level? How is a nation’s happiness or well-being to be measured? There is general acceptance that GDP is a relatively poor proxy for national well-being and is more a measure of production. There have been various indices developed over the years (see, for example, Box 14.7 on ISEW in Economics, 7th edition) as alternatives to GDP. None has been adopted by governments, however, with the exception of a Gross National Happiness index in Bhutan.

Recently, however, there has been renewed interest in developing an index of well-being. In France, President Sarkozy commissioned two Nobel economists, Joseph Stiglitz and Amartya Sen, to examine the issues in developing such a measure. In the light of the Stiglitz/Sen report, David Cameron has asked the Office of National Statistics to measure the UK’s general well-being. The articles below look at the difficulties that could arise in producing an index of well-being, of meauring the elements and in using it for policy.

  2. Summarise the main findings of the Stiglitz/Sen/Fetoussi report.
  3. What items would be included in a happiness or well-being index that (a) are not included in GDP; (b) not included in Stiglitz and Sen’s proposed net national product measure? How would such an index be compiled?
  4. Would it be satisfactory to compile such an index purely on the basis of survey evidence? Why might such evidence prove unreliable?
  5. What are the political advantages and disadvantages of using such an index?
  6. Is utilitarianism the best basis for judging the progress of society?

Most people, when asked, would like to earn more and many people are prepared to make sacrifices to do so. They may devote considerable time to obtaining qualifications; work much harder in order to gain promotion; work longer hours. What is more, when people do earn more, they take on extra commitments: a bigger house with a bigger mortgage; sending their kids to a private school; getting used to a more luxurious lifestyle. In fact, many people have to spend more on things such as home help, convenience foods and all sorts of labour-saving devices in order to cope with their longer hours.

Some people get so fed up with this pressurised lifestyle that they say ‘enough is enough; let me off this merry-go-round’. They may be happy to take a cut in income to live a simpler life and have more leisure time. Others, however, find that the merry-go-round just keeps going faster and faster and that they cannot get off; except, perhaps, if they make themselves ill, or worse still, die!

Now, if you are struggling as a student to make ends meet and find your debts are inexorably mounting, you may have little sympathy for people earning six-figure salaries! But are you in danger of trying to achieve this lifestyle for yourself? Do you see the main goal of your degree as getting you a better-paid job? What would count as ‘rational behaviour’ here and what would an economist advise you to do?

Then there is the question of whether the high paid are worth their high salaries. Are these salaries a reflection of the value of their output and the sacrifices they make? Or do they reflect economic power, custom and practice or asymmetry of information? And what do we mean by ‘worth’?

The following articles look at some of the highest paid people in the public sector. Some 38,000 public-sector employees earn more than £100,000. In the private sector the figures are much higher: some 545,000 people.

Questions

  1. Use Gini coefficients to examine what has happened to income distribution in the UK in recent years.
  2. Are high-paid earners ‘worth’ what they are paid? How would set about establishing what they are worth?
  3. Is it rational to seek a higher paid job if it involves longer hours and more stress? Why may it be difficult to make a ‘rational’ decision?
  4. Should the Prime Minister be the highest paid public-sector employee? Explain your answer.
  5. What factors will you take into account when deciding what jobs to apply for?
  6. To what extent can imperfect information explain people’s choices about work-life balance?
  7. To what extent can marginal productivity explain the huge salaries and bonuses paid to top executives in both the public and the private sectors?

If we are faced with simple and limited choices, we may make careful decisions based on a number of criteria: in other words, we will identify various characterisitics we are looking for and see how well the various alternative products or activities meet our criteria. When we have lots of choice, however, we may be less careful or get confused.

In this Guardian podcast, the panelists discuss complex choices between many products and/or characteristics. Are people being ‘rational’ when making such choices? Is being less careful simply a rational use of scarce time? Do people really want lots of choice or would they prefer more limited choice? Can experiments where people are given choices help us to understand how people choose and how much choice businesses or government should give people? Then there is the question of producers/suppliers of products. Does choice promote competition and product development and is there an optimum amount of choice to achieve this?
