Question
Assume Alice’s preferences satisfy the axioms of the expected utility theorem. A risky assetyields 3 utility or $0 utility with equal probability in abear market. The probabilities of a bull or a bear market are the same (i.e., 50%). What is Alice’sexpected utility from the risky asset?[Write your answer as a number with a maximum of two decimals, lik
Solution
The expected utility from the risky asset can be calculated by multiplying the utility of each outcome by its probability and then summing these products.
In a bull market, the utility is $8 and the probability is 50% (or 0.5). So, the expected utility from a bull market is 8 * 0.5 = 4.
In a bear market, the utility can be either 0, each with equal probability. So, the expected utility in a bear market is (3 * 0.5 + 0 * 0.5) = 1.5.
Therefore, Alice's expected utility from the risky asset is the sum of the expected utilities from the bull and bear markets, which is 4 + 1.5 = 5.5.
