The expected utility hypothesis is a fundamental concept in mathematical economics that assumes rational agents make decisions by maximizing utility, or the subjective desirability of their actions. This hypothesis is a cornerstone of rational choice theory, which models aggregate social behavior. The expected utility hypothesis states that agents choose between risky prospects by comparing expected utility values, calculated as the weighted sum of utility values of payoffs multiplied by their probabilities. This concept has been influential in fields such as microeconomics, game theory, and decision theory, with key contributors including Daniel Bernoulli, Leonard Savage, and John von Neumann. The expected utility hypothesis has been applied in various contexts, including finance, insurance, and public policy, with applications such as portfolio optimization and risk management. However, the hypothesis has also faced criticisms and challenges, including the Allais paradox and the Ellsberg paradox, which have led to the development of alternative theories such as prospect theory and regret theory.

The expected utility hypothesis has its roots in the work of Daniel Bernoulli, who first introduced the concept of expected utility in the 18th century. The hypothesis was later developed and refined by Leonard Savage and John von Neumann in the 20th century. The concept has since become a cornerstone of rational choice theory, which models aggregate social behavior. The expected utility hypothesis has been influential in fields such as microeconomics, game theory, and decision theory, with applications in finance, insurance, and public policy.

The expected utility hypothesis works by assuming that rational agents make decisions by maximizing utility, or the subjective desirability of their actions. The hypothesis states that agents choose between risky prospects by comparing expected utility values, calculated as the weighted sum of utility values of payoffs multiplied by their probabilities. The formula for expected utility is U(p) = ∑ u(x_k) p_k, where u(x_k) is the utility value of payoff x_k and p_k is the probability of payoff x_k. This concept has been applied in various contexts, including portfolio optimization and risk management.

Key facts about the expected utility hypothesis include that it assumes rational agents make decisions by maximizing utility, and that the hypothesis has been influential in fields such as microeconomics, game theory, and decision theory. The hypothesis has been applied in various contexts, including finance, insurance, and public policy, with applications such as portfolio optimization and risk management. The expected utility hypothesis has also faced criticisms and challenges, including the Allais paradox and the Ellsberg paradox, which have led to the development of alternative theories such as prospect theory and regret theory.

Key people associated with the expected utility hypothesis include Daniel Bernoulli, Leonard Savage, and John von Neumann. These individuals have made significant contributions to the development and refinement of the hypothesis. Other notable contributors include Milton Friedman and Gary Becker, who have applied the hypothesis in various contexts. The expected utility hypothesis has also been influenced by the work of Amos Tversky and Daniel Kahneman, who have developed alternative theories such as prospect theory.

The expected utility hypothesis has had a significant cultural impact and influence, with applications in various fields such as finance, insurance, and public policy. The hypothesis has been used to model aggregate social behavior and has been influential in the development of rational choice theory. The expected utility hypothesis has also faced criticisms and challenges, including the Allais paradox and the Ellsberg paradox, which have led to the development of alternative theories such as prospect theory and regret theory.

The current state of the expected utility hypothesis is that it remains a widely used and influential concept in mathematical economics. However, the hypothesis has also faced criticisms and challenges, including the Allais paradox and the Ellsberg paradox, which have led to the development of alternative theories such as prospect theory and regret theory. Recent developments include the application of the hypothesis in new contexts, such as behavioral economics and neuroeconomics.

Controversies and debates surrounding the expected utility hypothesis include the Allais paradox and the Ellsberg paradox, which have led to the development of alternative theories such as prospect theory and regret theory. Other criticisms include the assumption of rationality and the lack of consideration for non-expected utility factors such as framing effects and loss aversion.

The future outlook for the expected utility hypothesis is that it will continue to be a widely used and influential concept in mathematical economics. However, the hypothesis will also face ongoing challenges and criticisms, including the development of alternative theories such as prospect theory and regret theory. Recent developments include the application of the hypothesis in new contexts, such as behavioral economics and neuroeconomics.

Practical applications of the expected utility hypothesis include portfolio optimization and risk management.
