Looking back at Table 4.10, what would happen if Maria’s reference point was to do her homework on Saturday, and what if it was to do it on Monday? How is this related to the concept of personal equilibrium that we looked at in the last chapter?

In section
Explain the difference between time- consistent and present- biased preferences.Why is this distinction not important in a model of exponential discounting?
Inter- temporal utility (as defined in equation (4.1)) is about measuring streams of utility over time. To make life easier for themselves, however, economists normally think about streams of money over time. This should be OK if we think in terms of, say, ‘$10’s worth of utility’, but could
Is prospect theory an example of over- fitting?
If loss aversion can lead to risk aversion, how can we tell the difference between loss aversion and risk aversion?
In many court cases there is no clear- cut defense and prosecution (e.g. divorce disputes). What does the fourfold pattern of risk attitudes predict in such cases?
Carefully explain why the overweighting of small probabilities can lead to tax evasion and frivolous litigation.
Why may a person’s decision to evade taxes be influenced by what his friends and colleagues are doing?
Carefully explain how we can estimate a person’s risk aversion by their choice of insurance deductible.
Is expected utility theory of any practical relevance?
and γ = 0.61, a person would pay $110 for an extra deductible of $500 if the claim rate was 4 percent. How much would a person be willing to pay to reduce the deductible by $165 if the claim rate is 25 percent?Comment on the numbers in Table 3.20.
that, applying the standard formulation of prospect theory, with λ = 2.25, β =
I argued in section
Are preference reversals caused by intransitive preferences or procedural invariance?
Is regret theory the same as a model of reference- dependent utility with a stochastic reference point?
What would happen to the equity premium if investors were less loss- averse or the evaluation period was longer? How often should you evaluate your investments?
One set of prospects considered by Loomes, Starmer and Sugden (1991) was the following: A = (0, $10; 0.6, $3), B = (0.7, $7.50; 0.3, $1) and C = (1, $5). What would you choose between A and B, B and C, and A and C? How can regret theory help us explain choices in this case?
What do you think is the relevant reference point of a prospect? How might the certainty effect be related to reference dependence?
In 1963 Paul Samuelson wrote about a colleague who said that he would turn down the prospect (0.5, −$100; 0.5, $200) but would accept 100 such prospects.Suppose that his utility function is u(x) = x − w if x ≥ w and u(x) = −2.5(w− x) if w > x, where w is his wealth. Show why he turned
Using prospect theory, say whether a person would prefer prospect I or prospects J to N from Table 3.6.
Using the model of disappointment with θ = 0.002, consider the following three prospects: A = (0.5, $2,400; 0.5, $0), B = (0.7, $2,400; 0.3, $0) and C = (0.3,$2,400; 0.7, $0). Work out the utility of each prospect and comment on the result.
Show why it is inconsistent with expected utility that most people choose prospect F over E, and prospect G over H, when the prospects are as in Table 3.5.
Explain why the indifference curves in a probability triangle diagram are straight lines if preferences satisfy expected utility theory. [Hint: we can write the expected utility of a prospect as U(x) = p1u(x1) + (1 − p2 − p3) u (x2) + p3u(x3).]
What are the advantages and disadvantages of using the 1/ n heuristic to choose investments?
Suppose that Anna owns her own house and house prices go up. Should she spend more? Now, suppose she has money invested in the stock market and share prices go down. Should she spend less?
Give reasons why fungibility may not hold.
Using search, contrast effects and reference dependence, suggest why a person who lives in an area where apartments cost around $200,000 may be reluctant to buy when she moves to an area where apartments cost around $300,000.
Does the fact that a taxi driver works nine hours a day mean he has a reference level of hours he wants to work?
What is ecological rationality and why is it important in understanding the efficiency of markets?
What effect do you think the internet has had on the validity of the law of one price?
How is it possible to detect lying in the lab when subjects are given tasks to do and self- report their success?
Write down a list of occasions when you could have gained from lying or deception. Why can context influence whether or not you lie?
Suppose someone’s willingness to pay for a good is $10 and their reference point is $20. If the good is $13, will they buy it? What does this tell us about sales and ‘bargain buys’?
Why would we expect EG to be greater than WTA?
Argue that, if true, the ‘no loss in buying’ hypothesis means the WTP valuation is more reliable than the WTA valuation.
List all the heuristics that have appeared in the chapter.

Why does it make sense to mix up experimental treatments and sessions –i.e. to have multiple treatments in each session and multiple sessions for each treatment?
Why does a heuristic usually come hand in hand with a cognitive bias? Should we emphasize how clever people are for having good heuristics, or how dumb they are for being biased?
