We study the nature of sharing resources in distributed collaborations such as Grids and peer-to-peer systems. By applying the theoretical framework of the multi-person prisoner's dilemma to this resource sharing problem, we show that in the absence of incentive schemes, individual users are apt to hold back resources, leading to decreased system utility. Using both the theoretical framework as well as simulations, we compare and contrast three different incentive schemes aimed at encouraging users to contribute resources. Our results show that soft-incentive schemes are effective in incentivizing autonomous entities to collaborate, leading to increased gains for all participants in the system.
