Prospect theory is a theory of the psychology of choice and finds application in behavioral economics and behavioral finance. ( [8] It has also been shown that narrow framing causes loss aversion among stock market investors. The theory continues with a second concept, based on the observation that people attribute excessive weight to events with low probabilities and insufficient weight to events with high probability. ( p , but since p , ) p ν This paper presents a method for axiomatizing a variety of models for decision making under uncertainty, including Expected Utility and Cumulative Prospect Theory. 100% chance to win $900.

It describes how people choose between probabilistic alternatives and evaluate potential losses and gains. ( [14] Or, with regards to domestic governance, politicians are more likely to phrase a radical economic policy as one ensuring 90% employment rather than 10% unemployment, because framing it as the former puts the citizenry in a "domain of gain," which is thereby conducive to greater populace satisfaction. /Border[0 0 0]/H/N/C[.5 .5 .5] /Subtype /Link ) The theory was cited in the decision to award Kahneman the 2002 Nobel Memorial Prize in … ( < stream ) 78 0 obj << ( /Border[0 0 0]/H/N/C[.5 .5 .5] CPP can explain all three stylized facts S1,S2,S3. stream endstream x ( ; , therefore: π − , / π v ( and Prospect-Theorie, von Markowitz eingeführte, von Kahneman und Tversky theoretisch vertiefter Ansatz und wichtigste Revision der SEU-Theorie, indem eine Beziehung zwischen subjektivem und objektivem Wert, oder besser dem Geldwert von Gütern, postuliert wird (Entscheidung, Präferenz). 2.

The third essay in Chapter 4 (co-authored with Maik Dierkes) proves that subproportionality as a property of the probability weighting function alone does not automatically imply the common ratio effect in the framework of Cumulative Prospect Theory.
