Let the punishment fit the criminal: An experimental study
通过实验室实验，研究人们是否会根据受罚者的主观体验调整惩罚力度，包括金钱和非金钱制裁，发现被试对更富有的人施加更高罚款，对更不愿做无聊任务的人分配更多重复次数。
We use a laboratory experiment to study the extent to which people tailor levels of punishment to the subjective experience of the person to receive that punishment, for both monetary and non-monetary sanctions. We find that subjects tend to apply higher fines to wealthier individuals. Additionally, subjects assign more repetitions of a tedious task to those with a lower willingness to pay to avoid it. We find no evidence that the distributions of monetary and non-monetary punishments are different when considered as proportions of the maximum possible punishment, but that this does not hold when non-monetary punishments are converted into monetary equivalents. This suggests that subjects do not have in mind a particular level of disutility from the punishment, but rather are guided by the sentencing possibilities.
