Q1. What is the primary focus of Prospect Theory according to Kahneman and Tversky?
- A. Maximizing expected utility
- B. Evaluating potential gains and losses relative to a reference point ✓
- C. Predicting rational decision-making in all situations

- A. People are always rational in their decisions
- B. People are risk-averse when facing potential gains ✓
- C. People treat losses and gains symmetrically

- A. Reference point
- B. Loss aversion
- C. Value function ✓

- B. People are equally sensitive to losses and gains
- C. People are more sensitive to gains than to losses

Module 3: Reference Dependence and Framing Effects
Reference Dependence and Framing Effects
Knowledge check
Q1. What is the key idea behind reference dependence in prospect theory?
- A. Outcomes are evaluated based on their absolute value
- B. Outcomes are evaluated relative to a reference point ✓
- C. Outcomes are always evaluated in terms of potential gains
- D. Outcomes are evaluated based on their probability
Why: Reference dependence means that people assess outcomes relative to a reference point rather than in absolute terms.
Q2. Which of the following is an example of a framing effect?
- A. Choosing a sure gain of $50 over a 50% chance to gain $100
- B. Choosing a 50% chance to lose $100 over a sure loss of $50
- C. Presenting the same information in terms of gains versus losses leading to different decisions ✓
- D. Always preferring a riskier option
Why: Framing effects occur when the way information is presented (as a gain or a loss) influences decision-making, even when the underlying facts are the same.
Q3. According to prospect theory, how do people generally perceive losses compared to gains?
- A. They perceive losses as more significant than gains ✓
- B. They perceive gains as more significant than losses
- C. They perceive losses and gains equally
- D. They do not perceive losses or gains
Why: Prospect theory suggests that losses have a greater psychological impact than equivalent gains, a concept known as loss aversion.
Q4. What does the term 'framing' refer to in prospect theory?
- A. The process of setting a reference point
- B. The way a decision problem is presented ✓
- C. The calculation of expected utility
- D. The evaluation of outcomes in terms of probabilities
Why: Framing refers to how a decision problem is presented, which can significantly influence the choices people make.
Q5. Which of the following is a consequence of reference dependence?
- A. People are always risk-averse
- B. People's decisions are influenced by how outcomes are framed ✓
- C. People ignore probabilities in their decisions
- D. People always make rational decisions
Why: Reference dependence leads to framing effects, where the same decision can be influenced by how the options are presented.

Module 5: Probability Weighting in Decision Making
Probability Weighting in Decision Making
Knowledge check
Q1. What is the term used to describe the phenomenon where people overweight small probabilities and underweight large probabilities?
- A. Probability weighting ✓
- B. Loss aversion
- C. Framing effect
- D. Reference dependence
Why: Probability weighting refers to the tendency of individuals to overweight small probabilities and underweight large probabilities, which is a key component of prospect theory.
Q2. According to prospect theory, how do people typically perceive probabilities close to 1?
- A. They overestimate them
- B. They underestimate them ✓
- C. They perceive them as certain
- D. They ignore them
Why: Prospect theory suggests that people tend to underestimate probabilities that are close to 1, meaning they do not perceive them as certain.
Q3. Which of the following is a consequence of probability weighting in decision making?
- A. People are more risk-averse in the domain of gains
- B. People are more risk-seeking in the domain of losses
- C. Both A and B ✓
- D. Neither A nor B
Why: Probability weighting leads to risk-averse behavior in the domain of gains and risk-seeking behavior in the domain of losses.
Q4. What does the probability weighting function look like graphically?
- A. It is linear
- B. It is convex for low probabilities and concave for high probabilities
- C. It is concave for low probabilities and convex for high probabilities ✓
- D. It is exponential
Why: The probability weighting function is typically concave for low probabilities (overweighting) and convex for high probabilities (underweighting), reflecting the distortion in perceived probabilities.
Q5. Which of the following best describes the impact of probability weighting on expected utility theory?
- A. It supports expected utility theory
- B. It challenges expected utility theory ✓
- C. It has no impact on expected utility theory
- D. It modifies expected utility theory to include risk preferences
Why: Probability weighting challenges expected utility theory by showing that people do not evaluate probabilities in a linear manner, which is a key assumption of expected utility theory.

- A. It is too linear
- B. It is not sufficiently sensitive to losses
- C. It fails to account for probability weighting ✓
- D. It assumes risk neutrality
