Data for: If future generations had a say: An experiment on fair sharing of a common-pool resource across generations

We test how inter-generational resource sharing is affected by a veto power of later generations. More specifically, we study in an online experiment the over-use of a common-pool resource (CPR) by early generations that comes at the expense of later generations and how veto-empowerment of the later generations can be used to restrain egoistic tendencies. We compare sequential ultimatum and dictator games of various lengths and find that (1) the CPR consumption of early generations does not depend on the number of generations that follow them; (2) veto-empowerment of later generations leads to a fairer but ultimately less efficient use of the CPR across generations; (3) vetoes are used more carefully if not only previous generations are affected by the veto but also future generations that did not have access to the resource yet.本研究旨在考察后代拥有否决权对代际资源共享行为的影响。具体而言，我们通过线上实验探究了早期世代以牺牲后代利益为代价过度消耗公共池塘资源（common-pool resource, CPR）的现象，以及赋予后代否决权如何能够抑制其利己行为倾向。本研究对比了不同时长的序贯最后通牒博弈与独裁者博弈，结果发现：（1）早期世代的公共池塘资源消耗量与后续世代的数量无关；（2）赋予后代否决权可使代际间公共池塘资源的使用更为公平，但最终会降低整体使用效率；（3）当否决权不仅影响前代群体，还波及尚未接触该资源的后代群体时，参与者会更为谨慎地行使否决权。
