The two sides of envy, destructive and constructive, give rise to qualitatively different equilibria, depending on the economic, institutional, and cultural environment. If investment opportunities are scarce, inequality is high, property rights are poorly protected, and social comparisons are strong, society is likely to be in the “fear equilibrium,” in which better endowed agents restrain the...

This paper addresses the role of affect and emotions in shaping the behavior of responders in the ultimatum game. A huge amount of research shows that players do not behave in an economically rational way in the ultimatum game, and emotional mechanisms have been proposed as a possible explanation. In particular, feelings of fairness, anger and envy are likely candidates as affective determinant...

We study envy-free mechanisms for assigning tasks to agents, where every task may take a different amount of time to perform by each agent, and the goal is to get all the tasks done as soon as possible (i.e., minimize the makespan). For indivisible tasks, we put forward an envy-free polynomial mechanism that approximates the minimal makespan to within a factor ofO(logm), wherem is the number of...

Five separate studies examined the associations of self-criticism and self-oriented perfectionism with goal pursuit across a variety of domains. Although self-criticism has previously been shown to be related to diminished goal progress, a controversy remains regarding the potential association between aspects of "positive perfectionism," such as self-oriented perfectionism, and enhanced goal p...
