(a)
Identify the expected income.
(a)

Explanation of Solution
In the given case, there is a 50% chance to make $4,000 in a month and another 50% chance to make nothing. Therefore, the expected income of L can be calculated as follows:
Thus, the expected income of L is $2,000.
Expected income: Expected income is the money value that of what a person expects to own at a given point of time.
(b)
Identify the expected utility.
(b)

Explanation of Solution
The given graph shows that when the income is $4,000, the corresponding utility is 100; when the income is $0, then the corresponding utility is also 0. Now the expected utility can be calculated as follows:
Thus, the expected utility of L is 50.
Expected income: Expected income is the money value of what a person expects to own at a given point in time.
(c)
Identify the amount that is offered by another firm with certainty to persuade L not to take the risky sales job.
(c)

Explanation of Solution
The given graph shows that the expected utility of L is 50. The corresponding wealth in the graph along the x-axis is $1,250. Hence, L would have to be offered about $1,250 a month with certainty to persuade L not to take the risky sales job.
Expected income: Expected income is the money value of what a person expects to own at a given point in time.
Expected income: Expected income is the money value of what a person expects to own at a given point in time.

The cost of risk is the difference between the expected income and the certain income offered by the other firms to persuade L not to take the risky sales job. Thus, the cost of risk can be calculated as follows;
The amount of the cost of risk is $750.
Cost of risk: The cost of risk is found by comparing the expected wealth in a given risky situation with the wealth that gives the same utility with no risk.
