We study the dynamics of a network of agents (players) under two models settings. In the first model, players (agents) extend heterogeneous cooperation levels to their partners and in the second, perfectly rational and selfish agents engage in an iterated Snowdrift Game and the evolution of the system suggests that cooperation emerges and prevails even when no external rules or norms for punish...

In this essay, I argue that human play is fundamentally selfish. Characteristics of individual and selfish play are observed and described within pve and pvp contexts of the MMORPG City of Heroes/Villains (Cryptic Studios). Analysis of player behaviors demonstrates the degree to which groups within MMORPGs attempt to restrict and transform individual and selfish play. In general, social play wi...

We provide an extention of GU model that incorporates a decision maker who is averse to inequality of allocations among other agents. We also provide a detaled discussion on the experiments on dictator games with an exit option.
