Rationality Test in Group with Externality Based on Experimental Economics
In recent years,many studies have proved that the information environment and information in-teraction have significant impacts on the accuracy and rationality of individual decision-making.However,most of the studies assume that the individual's decision only affects their own profit,and that the individu-al only affects beliefs and thus decision-making through the transmission of information.In daily life,the relationship between groups composed of individuals often determines the way the utility is distributed,which in turn affects the individual's decision-making mode.This paper uses the experimental method of in-ter-group control to explore the impact of the externality of income on decision rationality and decision effi-ciency.By improving the ball-drawing experiment setup used by scholars such as Holt in their research and explaining relevant conclusions through the establishment of an incentive utility model,it is found that compared with the situation that decision-making only affects the individual's own utility,the individual's decision-making is more rational when there is an income externality.
