The study of moral emotions (i.e. Schadenfreude and envy) is critical to understand the ecological complexity of everyday interactions between cognitive, affective, and social cognition processes. Most previous studies in this area have used correlational imaging techniques and framed Schadenfreude and envy as unified and monolithic emotional domains. Here, we profit from a relevant neurodegene...

Ž . This paper argues that it is important to include the other party’s payoff in a competitor’s utility satisfaction function. Ž . Examples of the impact are provided as well as implications for multi-stage games competitions . A sample of 200 provides empirical support for the critical role other party results play in satisfaction, in particular the importance of relative payoffs. Several imp...

Economic concerns for equity have motivated game theorists to study envy-free mechanisms. Though not incentive compatible, these mechanisms implement in Nash equilibria efficient allocations at which no agent prefers the consumption of any other agent to their own. In experimental allocation decisions between two players, an envy-free first-price auction achieves similar efficiency and far grea...

We study mechanisms for an allocation of goods among agents, where agents have no incentive to lie about their true values (incentive compatible) and for which no agent will seek to exchange outcomes with another (envy-free). Mechanisms satisfying each requirement separately have been studied extensively, but there are few results on mechanisms achieving both. We are interested in those allocat...

Division of a resource among multiple agents is a frequent problem in multiagent systems and fair, efficient, and decentralized allocation procedures are highly valued. A division of a resource or good is envy-free when every agent believes that its share is not less than anyone else’s share by its own estimate. As envy-free procedures are not efficient (in the sense of Pareto optimality) we ha...

While every instance of the Hospitals/Residents problem admits a stable matching, the problem with lower quotas (HR-LQ) has instances with no stable matching. For such an instance, we expect the existence of an envy-free matching, which is a relaxation of a stable matching preserving a kind of fairness property. In this paper, we investigate the existence of an envy-free matching in several set...
