Prospect theory

Prospect theory is one of the most influential theories of decision-making under risk. The theory draws on psychology and has been proposed as an alternative to expected utility theory. It substitutes a value function for the utility function, and a decision weights function for probabilities. Its main ideas are that changes in wealth are more important than absolute levels of wealth for describing risk-taking, and that decision weights is a non-linear function of probability.

Scientific Research An Academic Publisher. A Review of Prospect Theory. It is concluded that in the decision-making process, people not only have intuitive biases, but also have frame dependence biases, representativeness biases, availability biases, anchoring effects, cognitive differences and affected groups. Therefore, people often make different and contradictory choices for the same problem at different times. Kahneman and Tversky [1] found that when making decisions with uncertainty, the ultimate utility of an individual is not simply the expected value of the possible future utility. They believe that individual psychological structure plays a key role in editing.

The study tested a series of binary financial risky choices, ultimately concluding that judgments formed under uncertainty deviate significantly from those presumed by expected utility theory, which was the prevailing theoretical construct at the time. In the forty years since publication, this study has had a remarkable impact on science, policy, and other real-world applications. At the same time, a number of critiques have been raised about its conclusions and subsequent constructs that were founded on it, such as loss aversion.


Prospect theory

Prospect theory is a theory of the psychology of choice and finds application in behavioral economics and behavioral finance. It was developed by Daniel Kahneman and Amos Tversky in Based on results from controlled studies , it describes how individuals assess their loss and gain perspectives in an asymmetric manner see loss aversion.

Prospect theory is a behavioral model that shows how people decide between alternatives that involve risk and uncertainty e. It demonstrates that people think in terms of expected utility relative to a reference point e. Prospect theory was developed by framing risky choices and indicates that people are loss-averse ; since individuals dislike losses more than equivalent gains, they are more willing to take risks to avoid a loss. Prospect theory has been applied in diverse economic settings, such as consumption choice, labor supply, and insurance Barberis,

ГЛАВА 19 - А вдруг кто-то еще хочет заполучить это кольцо? - спросила Сьюзан, внезапно заволновавшись.  - А вдруг Дэвиду грозит опасность. Стратмор покачал головой: - Больше никто не знает о существовании кольца. Именно поэтому я и послал за ним Дэвида. Я хотел, чтобы никто ничего не заподозрил.

 Его погубило слабое сердце - вот так. Слишком уж удобная версия. Стратмор пожал плечами.

 Тридцать секунд.

 Джабба хотел сказать, что это, возможно, не шифр-убийца. - Конечно же, это убийца! - закричал Бринкерхофф.  - Что еще это может. Иначе Танкадо не отдал бы ключ.

Эхо выстрела слилось с царившим вокруг хаосом. Сознание гнало ее вперед, но ноги не слушались. Коммандер. Мгновение спустя она, спотыкаясь, карабкалась вверх по ступенькам, совершенно забыв о таящейся внизу опасности. Она двигалась вслепую, скользя на гладких ступеньках, и скопившаяся влага капала на нее дождем.

 Верно! - сказал Беккер с экрана.  - Может быть, у этих элементов разное число протонов или чего-то. Если вычесть… - Он прав, - сказал Джабба, повернувшись к Соши.
