This paper investigates how punishment promotes cooperation when the punishment enforcer is a third party independent of the implicated parties who propose the punishment. In a prisoner's dilemma experiment, we find an independent third party vetoes not only punishment to the cooperators but...

Punishment can lose its legitimacy if the enforcer can profit from delivering punishment. We use a controlled laboratory experiment to examine how justification can combat profit-seeking punishment and promote the legitimacy of punishment. In a one-shot sender-receiver game, an independent third...

This paper examines the deterrence effect of two auditing rules via a laboratory experiment. A traditional rule which is usually assumed in the auditing literature, audits a taxpayer with a constant probability, which is independent of others' tax returns. A bounded rule recently proposed and...

The need for justification is a widely observed social phenomenon. This paper develops a theoretical framework and reports laboratory evidence to show how pure justification pressure affects cooperative behavior in economic exchange environments. In a one-shot anonymous interaction, compared...

Reputation systems that rely on feedback from traders are important institutions for helping sustain trust in markets, while feedback information is usually considered a public good. We apply both theoretical models and experiments to study how raters' feedback behavior responds to different...

Inequity aversion and reciprocity have been identified as two primary motivations underlying human decision making. However, because income and wealth inequality exist to some degree in all societies, these two key motivations can point to different decisions. In particular, when a beneficiary...

People often experience the benefits of taxation with time. We design experiments to test the hypothesis that delaying the benefits of taxation can lead to low support for taxes. In a dynamic market experiment with negative externalities, we consistently find that people are less willing to...
