On the Design of Peer Punishment Experiments
研究指出同伴惩罚实验中的“罚金-费用”比率可能扭曲结果，常用技术隐含可变比率，混淆了惩罚动机、对象和强度的实证发现。
Abstract Some peer punishment technologies may bias experimental results in unwanted ways. A critical parameter to consider in the design is the “fine-to-fee” ratio, which measures the income reduction for the targeted subject relative to the cost for the subject who requested the punishment. We show that a punishment technology commonly used in experiments embeds a variable fine-to-fee ratio and show that it could confound the empirical findings about why, whom, and how much subjects punish.
