Q

What is the key difference between Expected Utility Theory and Prospect Theory?

A

Q

What is loss aversion in Prospect Theory?

A

Loss aversion refers to the tendency for people to feel losses more intensely than gains of the same magnitude. The value function is steeper for losses than for gains.

Q

What is Bayes’ Theorem, and how is it used in decision-making?

A

Bayes’ Theorem calculates the probability of an event based on prior knowledge and new evidence. It helps update beliefs in light of new information.

Q

How does framing affect risk-taking behavior?

A

People are risk-averse for gains but risk-seeking for losses, depending on whether a situation is framed as a potential gain or loss.

Q

What is the Allais paradox, and what does it illustrate?

A

The Allais paradox shows that people’s preferences violate Expected Utility Theory, as they are influenced by certainty and probability distortions.

Q

How does Prospect Theory explain the preference for insurance?

A

People overweight small probabilities of large losses, making insurance appealing even if the expected value is negative.

Q

Why do investors monitor portfolios less frequently under Prospect Theory?

A

Frequent monitoring increases the perception of losses, which are felt more intensely due to loss aversion.

Q

What is the sunk cost fallacy?

A bias where people continue investing in a losing endeavor due to prior investments, even when it’s irrational to do so.

Q

What does the value function in Prospect Theory look like, and what are its key characteristics?

A

It is concave for gains, convex for losses, and steeper for losses, reflecting diminishing sensitivity and loss aversion.

Q

What is diminishing sensitivity in the value function?

A

The psychological impact of changes decreases as the magnitude of gains or losses increases (e.g., the difference between $10 and $20 feels larger than $1000 and $1010).

Q

Why do people overweight small probabilities in Prospect Theory?

A

Due to the probability weighting function, which magnifies the perceived likelihood of rare events.

Q

How does the certainty effect influence decision-making?

A

People give disproportionately high weight to outcomes that are certain, preferring guaranteed outcomes over probabilistic ones, even if the latter has a higher expected value.

20
Q

What is the reflection effect in Prospect Theory?

A

It describes how people are risk-averse for gains but risk-seeking for losses.

21
Q

What is hindsight bias?

A

The tendency to see past events as more predictable than they actually were.

22
Q

How does the conjunction fallacy arise?

A

When people judge a conjunction of two events (e.g., “Linda is a feminist and a bank teller”) as more probable than a single event, violating probability laws.

23
Q

What is confirmation bias?

A

The tendency to search for, interpret, and recall information that confirms pre-existing beliefs.

24
Q

How does the availability heuristic distort judgment?

A

It leads people to overestimate the likelihood of events that are vivid or recent in memory.

25
What is the difference between framing and anchoring?
Framing affects how choices are presented (gain vs. loss), while anchoring biases decisions toward an initial reference point.
26
Why do people tend to be risk-averse for gains?
Gains are valued less as they increase (diminishing sensitivity), making people prefer smaller, certain rewards.
27
What is ambiguity aversion?
The preference for known risks over unknown risks, even when the expected outcomes are the same.
28
How does the fourfold pattern of risk attitudes explain behavior in low and high probabilities?
People are risk-seeking for low-probability gains and high-probability losses but risk-averse for low-probability losses and high-probability gains.
29
What is the role of regret in decision-making?
Anticipating regret influences choices, as people aim to avoid future feelings of regret, even if it leads to suboptimal decisions.
30
How does Expected Utility Theory explain risk preferences?
It assumes people maximize the expected utility of outcomes, with utility diminishing as wealth increases.
31
How does Prospect Theory explain why people buy lottery tickets?
People overweight the small probability of winning (probability weighting) and are drawn to the large potential gain.
32
Why might people avoid selling losing stocks?
Due to the disposition effect, where they hold onto losses to avoid realizing them, consistent with loss aversion.
33
How does framing affect medical decisions?
A treatment framed as "90% survival rate" is more appealing than "10% mortality rate," even though the outcomes are identical.
34
Why do people overpay for extended warranties?
They overweight the small probability of product failure, consistent with probability weighting.
35
How does mental accounting influence spending behavior?
People treat money differently based on its source or intended use (e.g., windfall gains vs. earned income).
36
Write the formula for Bayes’ Theorem.
P(A∣B)= P(B∣A)⋅P(A) / P(B) ​
37
What are the parameters in Prospect Theory's value function?
v(x)=x^𝛼 for gains, −𝜆 (−𝑥)^𝛽 for losses, where 𝛼,𝛽 capture diminishing sensitivity and 𝜆>1 represents loss aversion.
38
How does the probability weighting function distort objective probabilities?
It overweights small probabilities and underweights large probabilities using: π(p)= p^γ / (p^γ+(1−p)^γ)^1/γ ​
39
What does a concave utility function imply about risk preferences?
It indicates risk aversion, as the marginal utility of wealth decreases with increasing wealth.
40
Calculate the expected utility for a gamble offering $100 with a 50% chance and $50 with a 50% chance. Assume 𝑢(𝑥)=√𝑥.
EU=0.5⋅√100+0.5⋅√50 =5+3.54=8.54.
41
Is it ethical to use framing to influence decision-making in public policy? Why or why not?
It depends; framing can simplify complex information but may also manipulate choices, undermining autonomy.
42
How does loss aversion explain the endowment effect?
Losses are felt more strongly than equivalent gains, so people demand more to give up an item than they would pay to acquire it.
43
What is a sunk cost, and why is it irrational to consider it in decision-making?
A sunk cost is a past expense that cannot be recovered. Rational decisions should be based on future costs and benefits, not past expenditures.
44
What is the significance of the Allais paradox?
It shows that real-world choices often violate the independence axiom of Expected Utility Theory, supporting Prospect Theory.
45
Why might people fail to update their beliefs correctly using Bayes’ Theorem?
Due to base rate neglect or misjudging conditional probabilities.
