An Experimental Study In Altruistic Rules' Effect On Gamer'risk Preference

With the rapid development of Experimental Economics and Behavioral Economics,altruistic rule game,especially represented by Ultimatum Games and trust games breaks the traditional hypothesis of rational-economic man.And game players' risk-taking behaviors and prosocial behaviors in the process of experiment make them deviate from the hypothesis of self-interest,which is becoming the research hot-spot of Behavioral Economics,psychology and sociology.As a consequence,scholars set about explaining the paradox of Experimental Game from the perspective of risk preference and social preference.Through experimental analysis of behavior,after then,scholars make further study on prosocial behavior and Specific social preference under the altruistic rule.But under the altruistic rule,research on risk preference is rare.Based on that,this paper makes a research on altruistic rule's effect on risk preference of game players and game behavior through the setting of altruistic rules and the control of altruistic objects' social distance,whose contents mainly consist of the following two aspects.(1)This paper examines the influence of altruistic rules on the risk preference of gamers in the context of infinite social distance between altruistic objects: the adapted BART experiment is used to achieve repeated game scenarios,controlling the infinite social distance between altruistic objects,and setting up questionnaires to investigate individual information such as age,gender,monthly disposable income and narcissistic personality traits of subjects,so that they can complete the altruistic rule game and the non-altruistic rule game separately,which compares and analyses the effects of altruistic rules on risk preference and game behavior of players,as well as the effects of individual factors on the experimental results.The results are as follows.(1)Under the situation of infinite social distance between altruistic objects,altruistic rules have a significant impact on the risk preference of gamers,and altruistic rules reduce the risk preference of gamers.(2)Narcissistic personality can reduce the interference of altruistic rules on players in the situation of infinite social distance between altruistic objects.(3)In the situation of infinite social distance,people are unwilling to engage in altruistic behavior even if they do not harm their own interests.(2)This paper examines the influence of altruistic rules on the risk preference of gamers in situations of different social distance of altruism objects: three groups of subjects with different social distance,namely strangers,friends and couples,are designed to complete the altruistic rule game and the non-altruistic rule game.The effects of different social distances on the experimental results are compared and analyzed.The results are as follows.(1)The difference of altruistic objects' social distance will lead to a striking difference between the effects of altruistic rules on the gamers' risk preference.To be specific,the altruistic rules significantly impact and increase the gamers' risk preference with the small social distance of altruistic objects,while the altruistic rules still significantly impact but decrease the gamers' risk preference with a bigger social distance of altruistic objects.At the same time,altruistic rules have an unapparent effect on gamers' risk preference,when altruistic objects are ordinary friends.(2)In the game of altruistic rules,the social distance of altruistic objects significantly impacts and lower the risk preference of the players.(3)In the game of altruistic rules,when confronted with altruistic objects with different social distances,the players behave as evading failure in the face of it,and the greater the social distance is between altruistic objects,the more sensitive the players are to their own failure.(4)The social distance of altruistic objects affects people's altruistic preferences.More exactly,the smaller the social distance is,the more willing people are to engage in altruistic behaviors.
