Experimental studies have shown that sanctions effectively deter free riding within groups. However, the over-use of costly punishment may actually harm overall welfare. A main reason for over-punishment is that free-riders generate negative emotions that likely favor excessive punishments. In...

In this paper, we examine labor market favoritism in a unique laboratory experiment design that can shed light on both the private benefits and spillover costs of employer favoritism (or discrimination). Group identity is induced on subjects such that each laboratory "society"consists of eight...

Do individuals trained in law enforcement punish or reward differently from typical student subjects? We analyze norm enforcement behavior of newly appointed police commissioners in both a Voluntary Contribution Mechanism game and a Common Pool Resource game. Our experimental design includes...

Recent examinations into the cognitive underpinnings of ethical decision making has focused on understanding whether honesty is more likely to result from deliberative or unconscious decision processes. We randomly assigned participants to a multi-night sleep manipulation, after which they...

Anti-social behaviours are costly to organizations, and the ability to identify predictors of such behaviours can be valuable. In this paper, we used a within-subjects laboratory design to study choices in the well-known (hypothetical) Trolley problem as well as in a real payoff money-burning...

We present a framework that incorporates both moral motivations and fairness considerations into utility. The main idea is that individuals face a preference trade-off between their material individual interest and their desire to follow moral norms. In our model, we assume that moral motivation...
