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?

Questions

  1. Are people ‘rational’ when they make choices? For what reasons may they not be rational?
  2. Can you make rational choices if your information is imperfect?
  3. Is there an optimum amount of choice and how would you set about establishing that optimum?
  4. How useful are experiments in understanding the process of choice? What are the weaknesses of such experiments?
  5. Should people be limited in the amount of choice they are given over medical treatment and schools?
  6. What are the advantages to other people of giving people more choice?
  7. How much does culture influence our attitudes towards choice?

Are consumers ‘rational’ is the sense of trying to maximise consumer surplus? In some circumstances the answer is yes. When we go shopping we do generally try to get best value for money, where value is defined in terms of utility. With limited incomes, we don’t want to waste money. If we were offered two baskets of goods costing the same amount, we would generally choose basket A if its contents gave us more utility than basket B.

So why do we frequently buy things that are bad for us? Take the case of food. Why do we consume junk food if we know fresh produce is better for us? To answer this we need to look a little closer at the concept of utility and what motivates us when we consumer things. The following article does just that. It reports on writings of Michael Pollan. Pollan looks at our motivation when choosing what and how much to eat. For much of the time our choices are governed by our subconscious and by habit.

“Millions of humans, while believing they govern their actions with conscious intelligence, clean every morsel from their dinner plates, mainly because their parents told them to. And we do this even if we don’t particularly like the food on the plate and even if we know we should be eating less of it. Unthinkingly, we follow a habit we would condemn if we looked at it clearly.”

Questions

  1. What is meant by ‘rational behaviour’? Is it reasonable to assume that people are rational in most circumstances?
  2. Is eating junk food consistent with the attempt to maximise consumer surplus?
  3. How relevant is the principle of diminishing marginal utility in explaining the amount of junk food we eat?
  4. To what extent are the problems that Pollan identifies examples of (a) imperfect information; (b) irrationality?
  5. What does people’s eating behaviour reveal about their preferences for the present over the future and hence their personal discount rate?
  6. What are the policy implications of Pollan’s analysis for governments trying to get people to eat more healthily?

The US Institute of Medicine of the National Academies has recently published a 92-page on report on childhood obesity and the use of taxes on junk foods to tackle the problem. In the report, titled Local Government Actions to Prevent Childhood Obesity, “a panel of experts suggested such taxes could play an important role in helping children make healthier eating choices”.

Meanwhile, in Australia, the Federal Government’s preventive health taskforce argued, amongst other things, that “junk food advertising should be phased out, the cost of cigarettes should be more than $20 a packet, and soft drinks and cask wine should be hit with higher taxes”.

So how effective are higher taxes in achieving a reduction in ill health associated with eating, drinking and smoking? If adopted, what is the socially optimum design and rates of such taxes? What other complementary policies could be adopted? The following articles consider the issues.

Questions

  1. For what reasons does the free market fail to achieve an optimum level of consumption of junk foods, alcohol and cigarettes?
  2. How would you determine the socially optimum level of consumption of such products?
  3. How are the price, income and cross-price elasticities of demand, and the price elasticity of supply, relevant to assessing the effectiveness of taxes for reducing the consumption of unhealthy products?
  4. What determines the incidence of taxes on unhealthy products?
  5. What other policies would you advocate to tackle the problems associated with consuming unhealthy products? How would they affect the price elasticity of demand for such products.
  6. To what extent do the objectives of social efficiency and equity conflict when designing appropriate policies to discourage unhealthy consumption?
