Consider two hypothetical jobs.
Job A provides a guaranteed annual income of $40,000.
Job B offers an uncertain income of $60,000 or $20,000, each with a 0.5 probability, resulting in an expected income of $40,000.
A risk-neutral person is indifferent between a guaranteed income and an uncertain income with the same expected value. They experience a constant marginal utility of income.
For example, Nancy gets a utility of 28 units from Job A.
Her expected utility from Job B is 14, weighted by its probability of 0.5, added to 42, weighted by its probability of 0.5. She gets the same utility of 28 units from both jobs, reflecting her risk-neutrality.
In contrast, a risk-loving person prefers an uncertain income over a guaranteed income with the same expected value. They experience an increasing marginal utility of income.
For example, Sarah gets a utility of 32 units from Job A and an expected utility of 42 from Job B. She chooses Job B, reflecting her risk-loving attitude.
Individuals make decisions based on their preferences toward risk. A risk-neutral person has constant marginal utility of income. This means that each…
