Measuring Loss Aversion under Ambiguity: A Method to Make Prospect Theory Completely Observable

Abstract: We propose a simple, parameter‐free method that, for the first time, makes it possible to completely observe Tversky and Kahneman's (1992) prospect theory. While methods existed to measure event weighting and the utility for gains and losses separately, there was no method to measure loss aversion under ambiguity. Our method allows this and thereby it can measure prospect theory's entire utility function. Consequently, we can properly identify properties of utility and perform new tests of prospect theory. We implemented our method in an experiment and obtained support for prospect theory. Utility was concave for gains and convex for losses and there was substantial loss aversion. Both utility and loss aversion were the same for risk and ambiguity, as assumed by prospect theory, and sign‐comonotonic trade‐off consistency, the central condition of prospect theory, held.

Does the Consciousness of the Disposition Effect Increase the Equity Premium

Abstract: The disposition effect is a well-established phenomenon in the empirical and experimental financial literature. It leads to sell winners too early and to hold losers too long. In this paper, we show that the consciousness of the disposition effect by investors lead them to require a greater risk premium to invest in stocks (when compared to rational investors). We also analyze the role of the evaluation period for disposition investors. We show that the risk premium they require is a decreasing function of the delay between two evaluations of their portfolio. The influence of the evaluation period on the equity premium looks like the one induced by myopic loss aversion (Benartzi-Thaler [1995]), but the origin is different. Valuing more often a portfolio gives more occasions to sell winning stocks and then decreases the expected return. This point is analyzed by assuming that returns are driven by a Brownian motion and that investors evaluate their portfolio at regularly spaced dates.

Emotion-induced loss aversion and striatal-amygdala coupling in low anxious individuals

Abstract: Adapting behavior to changes in the environment is a crucial ability for survival but such adaptation varies widely across individuals. Here, we asked how humans alter their economic decision-making in response to emotional cues, and whether this is related to trait anxiety. Developing an emotional decision-making task for functional magnetic resonance imaging, in which gambling decisions were preceded by emotional and non-emotional primes, we assessed emotional influences on loss aversion, the tendency to overweigh potential monetary losses relative to gains. Our behavioral results revealed that only low-anxious individuals exhibited increased loss aversion under emotional conditions. This emotional modulation of decision-making was accompanied by a corresponding emotion-elicited increase in amygdala-striatal functional connectivity, which correlated with the behavioral effect across participants. Consistent with prior reports of 'neural loss aversion', both amygdala and ventral striatum tracked losses more strongly than gains, and amygdala loss aversion signals were exaggerated by emotion, suggesting a potential role for this structure in integrating value and emotion cues. Increased loss aversion and striatal-amygdala coupling induced by emotional cues may reflect the engagement of adaptive harm-avoidance mechanisms in low-anxious individuals, possibly promoting resilience to psychopathology.

Emotional State and Market Behavior

Abstract: We consider the relationship between the emotional state of traders and market prices. We create asset markets with the structure first studied by Smith, Suchanek and Williams (1988), which is known to generate price bubbles and crashes. We analyze participants' facial expressions with facereading software before and while the market is operating. We find that greater positive emotion in facial expressions before the market opens predicts higher prices and larger bubbles. Greater fear predicts lower prices and smaller bubbles. Those traders who remain the most neutral during periods of market volatility achieve the highest earnings. Loss aversion in decision making is correlated with fear, not with other emotions.

Economic decisions for others: an exception to loss aversion law

Abstract: In everyday life, people often make decisions on behalf of others. The current study investigates whether risk preferences of decision-makers differ when the reference point is no longer their own money but somebody else money. Thirty four healthy participants performed three different monetary risky choices tasks by making decisions for oneself and for another unknown person. Results showed that loss aversion bias was significantly reduced when participants were choosing on behalf of another person compared to when choosing for themselves. The influence of emotions like regret on decision-making may explain these results. We discuss the importance of the sense of responsibility embodied in the emotion of regret in modulating economic decisions for self but not for others. Moreover, our findings are consistent with the Risk-as-feelings hypothesis, suggesting that self-other asymmetrical behavior is due to the extent the decision-maker is affected by the real and emotional consequences of his/her decision.
