Australia is a rich country. It is one of the few to have avoided a recession. This has been the result partly of successful macroeconomic policies, but largely of the huge mining boom, with Australia exporting minerals to China and other fast growing Asian economies.

But has this growth brought happiness? Are Australians having to work harder and harder to pay for their high standard of living? Indeed, do higher incomes generally result in greater happiness? The following articles explore this issue, both in an Australian context and more broadly. They look at some recent evidence.

For example, in one study, Canadian, Chinese, Indian, and Japanese university students were asked what they held to be most important for assessing the worth of their lives. The crucial finding was that although higher incomes may be a contributing factor to increased happiness and well-being, especially for poorer people, other factors are more important. These include developing fulfilling personal relationships, whether with partners, family members or friends; gaining knowledge and wisdom; having enjoyable hobbies; having financial security (as opposed to higher incomes); having a worthwhile career; living a moral life; helping other people.

The question then arises whether our economic systems and incentives are geared towards achieving these outcomes. Or are we encouraged to consume more and more and to seek higher and higher incomes to feed our addiction to consumption?

Is there an information problem here? Do many individuals perceive that money will buy them happiness, whereas, in reality, money can’t buy them love?

Questions

  1. Distinguish between necessary and sufficient conditions. Is higher income a necessary or sufficient condition (or both or neither) for an increase in happiness? Does a person’s circumstances affect the answer to this question?
  2. Explain what is meant by ‘rational behaviour’ at the margin in the traditional economic sense?
  3. If a person always behaved rationally, would they be happier than if they did not? Explain.
  4. Explain how information asymmetry between the two or more parties involved in a transaction may make people worse off, rather than better off, even though they were behaving rationally.
  5. Explain what is meant by diminishing returns to income.Do richer countries get happier as they get richer?
  6. How would you set about measuring happiness?
  7. What do you understand by the term ‘hedonic elevation and decline’? Does this provide an accurate description of you own purchasing behaviour? If so, explain whether or not you would like to change this behaviour.
  8. When people make economic decisions, these are normally made with bounded rationality. How may this affect the desirability of the outcomes of the decisions?
  9. In explaining bankers’ behaviour, Christopher Howse (author of the second Telegraph article above) states: ‘It’s the power game that keeps them happy, not the money itself. When I say “keeps them happy” I mean “feeds their addiction”. It is a negative kind of satisfaction. A morning spent without the distraction of making big bucks is a morning left exposed to the empty horror of being a little rational animal on the bare surface of the Earth lost in space.’ Do you agree? Explain why or why not.
  10. When people are addicted to something, would doing more of it be classed as irrational? Explain.
  11. Why are the Chinese so sad?

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?

Researchers at the California Institute of Technology have shown that a person’s enjoyment of wine is heightened if they are told that the wine is an expensive one. So what are the main factors determining the demand for wine? Is it really the taste or is it simply the expectation resulting from the price?

Questions

2. Analyse how utility theory can help to explain the level of demand for more expensive wine.
3. How would marginal utility and market demand be affected by the knowledge that bottle of wine is a relatively expensive one?
