Question 11

The Tversky-Kahneman prospect theory is a mathematical model of decision making under risk that assumes that:

People are more sensitive to losses than to gains.
People are more risk-averse in the domain of gains than in the domain of losses.
People overweight small probabilities and underweight large probabilities.
All of the above.

Answer

Correct Option: D

Question 12

The cumulative prospect theory is a mathematical model of decision making under risk that is an extension of the prospect theory that assumes that:

The value of a gain or loss is a function of its magnitude and its probability.
The value of a gain or loss is a function of its magnitude and its rank in the distribution of possible outcomes.
The value of a gain or loss is a function of its magnitude, its probability, and its rank in the distribution of possible outcomes.
None of the above.

Answer

Correct Option: C

Question 13

The rank-dependent utility model is a mathematical model of decision making under risk that assumes that:

The value of an outcome is a function of its rank in the distribution of possible outcomes.

The value of an outcome is a function of its probability and its rank in the distribution of possible outcomes.
The value of an outcome is a function of its magnitude, its probability, and its rank in the distribution of possible outcomes.

Answer

Correct Option: A

Question 14

The mean-variance model of portfolio selection is a mathematical model that assumes that:

None of the above.

Answer

Correct Option: A
