内容提要:
Social preference has been widely observed and is taken as the foundation of many policies targeting at voluntary behaviors such as donation. We report a field experiment in which we promote prosocial behavior by making the information about the cost of social resources more salient to the agents. The experiment is conducted at a major research university with all faculty and administrative staffs from two schools as participants. The university features an online system through which all employees order stationeries and other office supplies. The ordered items are used for work-related purposes, so they do not incur any cost to the employees but rather the cost is borne by the university. We randomize half of our subjects into a treatment group in which they were provided with the cost information of each item when ordering, while subjects in the control group do not receive such information. The experimental results show that displaying the costs reduces the quantities of ordered items. The effect is both statistically (p = 0.011) and economically significant (10.77% reduction). Moreover, we find that this effect only pertains to the extensive margin (i.e. quantity of varieties) but not the intensive margin (i.e. quantity for a given item). We also find that the treatment generates some efficiency gains for the university in terms of the reduction of cost of the orders.
