We study the inefficiency of equilibria for several classes of games when players are (partially) altruistic. We model altruistic behavior by assuming that player i’s perceived cost is a convex combination of 1−αi times his direct cost and αi times the social cost. Tuning the parameters αi allows smooth interpolation between purely selfish and purely altruistic behavior. Within this framework, ...

The concept of altruism is used in very different forms by computer scientists,economists, philosophers, social scientists, psychologists and biologists. Yet, in order to be useful in social simulations, the concept "altruism" requires a more precise meaning. A quantitative formulation is proposed here, based on the cost/benefit analysis of the altruist and of society at large. This formulation...

In a growing number of transplant centers worldwide, altruistic donors are accepted to anonymously donate a kidney to a stranger. An important hesitation to expand these transplantation programs is the fear of evoking psychological distress in the altruistic donor after donation. To what extent this fear is justified has not yet been systematically investigated. In this study, 24 altruistic don...

Media access control is an essential part of wireless communication. To achieve higher communication throughput multi-channel MAC has been studied. Adhoc wireless network’s performance is always measured corresponding to the power consumption of the nodes. The overall network connectivity depends on the energy of the nodes. Researchers have proposed many energy efficient MAC protocols to resolv...

A common form of Corporate Social Responsibility (CSR) by firms is to agree to donate a fixed portion of private good revenues to a charitable cause. In this paper we explore a new rationale for such CSR. We argue that linking private good purchase with charitable donations allows the firm to price discriminate between altruistic consumers who wish to make charitable donations out of their inco...

Moral decision making involves affective and cognitive functions like emotional empathy, reasoning and cognitive empathy/theory of mind (ToM), which are discussed to be subject to age-related alterations. Additionally, sex differences in moral decision making have been reported. However, age-related changes in moral decision making from early to late adulthood and their relation to sex and neur...
