We present a novel approach for modelling self serving bias by way of reference dependence. Bias is modelled as a systematic individual level deviation of the endogenous reference point from the expected price of a good in a two person k-double auction. We find that bias decreases the efficiency of the model, and that efficiency is decreasing in both the level of bias and reference dependence.  相似文献

Experimental studies have demonstrated that a typical investor derives utility of the gain and loss, relative to certain reference point, realized at each sale of a stock, and that the reference point adapts asymmetrically to the stock's prior gains and losses in that the adaptation to a gain is more substantial than to a comparable loss. This empirical finding motivates us to consider a dynamic trading problem in which an agent decides when to sequentially sell and buy a stock in order to maximize her utility of terminal wealth and realized gains and losses based on a reference point that adapts asymmetrically to the stock's prior gains and losses. We show that this agent is more reluctant to sell the stock at a loss than another agent whose reference point does not adapt to the stock gain or loss at all, leading to a higher percentage of gains realized (PGR) and a lower percentage of losses realized (PLR). We also show that when the agent weighs the utility of realized gains and losses more heavily in her investment criteria, she trades the stock more frequently, the PGR becomes lower, and the PLR becomes higher.  相似文献

This paper quantifies the notion of greed, and explores its connection with leverage and potential losses, in the context of a continuous‐time behavioral portfolio choice model under (cumulative) prospect theory. We argue that the reference point can serve as the critical parameter in defining greed. An asymptotic analysis on optimal trading behaviors when the pricing kernel is lognormal and the S‐shaped utility function is a two‐piece CRRA shows that both the level of leverage and the magnitude of potential losses will grow unbounded if the greed grows uncontrolled. However, the probability of ending with gains does not diminish to zero even as the greed approaches infinity. This explains why a sufficiently greedy behavioral agent, despite the risk of catastrophic losses, is still willing to gamble on potential gains because they have a positive probability of occurrence whereas the corresponding rewards are huge. As a result, an effective way to contain human greed, from a regulatory point of view, is to impose a priori bounds on leverage and/or potential losses.  相似文献

We conduct a field experiment, based on a registered report accepted by the Journal of Accounting Research, to test performance effects of setting a high reference point for peer‐performance comparison. Relative to providing the median as a reference point for online students to compare themselves to, providing the top quartile: damps performance for those below the median, boosts performance for those between the median and top quartile, and, in the case of outcome but not process comparison, boosts performance for those above the top quartile. We do not find that either reference point yields a greater average performance effect. However, providing the more effective reference point in each partition of initial performance yields a 40% greater performance effect than providing either reference point uniformly. Students access the online courses intermittently over the span of a year. Our effects derive from small portions of our treatment groups—5% in the case of process comparison and 26% in the case of outcome comparison—who accessed treatment and who were, on average, more active leading up to and during our intervention.  相似文献

Understanding the determinants of consumers’ willingness to pay (WTP) is an important challenge especially for practitioners. This study evaluates the effect of external information (eWOM valence and volume) and internal information (internal reference price) on consumers’ WTP for an accommodation. The results of an online experiment (n = 766) show a direct effect of valence on WTP which is strengthened by both volume and the internal reference price. Consumers with high reference prices are more sensitive to the effect of an increase in valence. Moreover, internal reference price has a non-linear influence on WTP. The findings suggest the relevant role of eWOM as well as internal reference price in determining consumers’ WTP. The inclusion of these two variables in dynamic pricing strategies could lead to greater benefits for hospitality managers.  相似文献
