Trust-game interactions and beliefs in continuous and "All-or-Nothing" investment action spaces.

In Gómez-Miñambres, Schniter, & Shields (2020) we conduct two between-subjects experiments to focus our research on “All-or-Nothing” options featured in many trust-based economic interactions. A fundamental issue with restricted investment action spaces is that their imposition may unintentionally affect reciprocity. Drawing from a student sample, we presented participants with an anonymous trust game. In these trust games we manipulate the investor’s action space. In the All-or-Nothing version investors can invest either “all” their endowment or “nothing”. In the other version, they can invest any amount of the endowment. In both versions, the experimenter multiplies the invested amount by three - creating potential gains from trust. Then the trustee receives this and decides how much to reciprocate to the investor. In a second experiment with another student sample we manipulate our description of the “trust game” (i.e. describing either the All-or-Nothing or Continuous version) to investigate effects on beliefs about investor trust and expectations about trustee reciprocity. This data is organized in two files, one for Experiment 1 and one for Experiment 2 described above. Each of these files has (1) a tab with the participants’ economic behavior in the experiment, and (2) a tab with a codebook explaining participants’ data.

本数据集源自Gómez-Miñambres、Schniter与Shields（2020）的研究，该团队开展了两项被试间实验（between-subjects experiments），旨在聚焦大量信任型经济互动中常见的全有或全无（All-or-Nothing）选项。受限投资行动空间存在一个核心问题：其强制推行可能会无意间对互惠（reciprocity）行为产生影响。研究以学生样本为被试，向其呈现匿名信任博弈（trust game）实验。在此类信任博弈中，我们对投资者的行动空间进行操控：在全有或全无版本中，投资者仅可选择投入全部禀赋（endowment）或零投入；而在另一版本中，投资者可投入任意额度的禀赋。两类实验中，研究者均会将投资金额乘以三倍，以此创造信任带来的潜在收益。随后受托人将获得该笔资金，并自主决定向投资者返还的互惠金额。在第二项针对另一组学生被试的实验中，我们通过调整“信任博弈”的描述方式（即分别采用全有或全无版或连续投入版的描述），探究其对投资者信任信念以及受托人互惠预期的影响。本数据集分为两个文件，分别对应上述实验1与实验2。每个文件包含两个工作表：(1) 记录被试在实验中的经济行为数据；(2) 包含解释被试数据的编码手册（codebook）。
