报告主题：Relative Framing of Public Good Contributions with Varying Endowment Distribution
内容摘要：Individual contributions to public goods can be framed as absolute amounts or as relative proportions of income. This paper examines the effect of such framing oncontributions of group members to a public good in a laboratory experiment.Group members have high and low amounts of endowed funds available tocontribute to the public good and the number of high-endowment members in each group varies between treatments. All participants play the public good game without and with minimal contribution level(MCL). We express the contributio nmetric and MCLs either as absolute amount or as a relative proportion of agroup member’s available endowment. The results of the experiment are consistent with our hypotheses that these institutional designs affect contribution behavior through shifting reference points of the members’ decisions. First,high-endowment members tend to contribute a lower proportion of their available funds compared with the low-endowment members. Second, average contribution in a group increases with the number of high-endowment members in the group.Third, the relative framing significantly reduces the probability that some members contribute all of their available funds. Fourth, the difference in average contributions between absolute and relative proportion mostly disappears when MCL is available.
