Prospect theory was a notable departure from these existing theories because it offered a descriptive theory of how people actually make decisions, rather than providing a perfectly rational account of how they ought to do so. As Narrow framing is a derivative result which has been documented in experimental settings by Tversky and Kahneman,[7] whereby people evaluate new gambles in isolation, ignoring other relevant risks. {\displaystyle \pi (0.01)\times v(-1000) −$501. Framing and prospect theory has been applied to a diverse range of situations which appear inconsistent with standard economic rationality: the equity premium puzzle, the excess returns puzzle and long swings/PPP puzzle of exchange rates through the endogenous prospect theory of Imperfect Knowledge Economics, the status quo bias, various gambling and betting puzzles, intertemporal consumption, and the endowment effect. An alternative solution to overcome these problems within the framework of (classical) prospect theory has been suggested as well. 0.01 >> ) Kahneman erhielt im Jahr 2002 den Nobelpreis für Wirtschaftswissenschaften für dieses Konzept und die … y ν ( ≥ Taylor and Francis. ( Short explanation of prospect theory, a central theory in behavioral economics. ( ′ 0 This paper presents a method for axiomatizing a variety of models for decision making under uncertainty, including Expected Utility and Cumulative Prospect Theory. The theory of "prospect and refuge" seeks to describe why certain environments feel secure and thereby meet basic human psychological needs. r ) {\displaystyle v} It has also been argued that prospect theory can explain several empirical regularities observed in the context of auctions (such as secret reserve prices) which are difficult to reconcile with standard economic theory. ≤ In the original formulation the term prospect referred to a lottery[citation needed]. The reliance on hypothetical choices raises obvious questions regarding the validity of the method and the generalizability of the results. {\displaystyle (x,p;y,q)} /D [105 0 R /XYZ 9.909 273.126 null] < >> endobj ( p q 90 0 obj << x ( x ′ ; /Subtype /Link Thus, contrary to the expected utility theory (which models the decision that perfectly rational agents would make), prospect theory aims to describe the actual behavior of people. 72 0 obj << π − /D [105 0 R /XYZ 10.909 272.126 null] [ 86 0 obj << 82 0 obj << >> endobj /Subtype /Link > /A << /S /GoTo /D (Navigation40) >> {\displaystyle \pi (pr)\nu (x)\leq \pi (pqr)\nu (y)} , which means that Π { \displaystyle \pi } is never linear foremost employed by IR theorists today, on security-related...
