We examine cooperative behavior when large sums of money are at stake, using data from the television game show <i>Golden Balls</i>. At the end of each episode, contestants play a variant on the classic prisoner's dilemma for large and widely ranging stakes averaging over $20,000. Cooperation is...

We consider the coupled dynamics of the adaption of network structure and the evolution of strategies played by individuals occupying the network vertices. We propose a computational model in which each agent plays a n-round Prisoner's Dilemma game with its immediate neighbors, after that, based...

Two pairs of two participants each interact repeatedly in two structurally independent but informationally linked Prisoner's Dilemma games. Neither pair receives feedback about past choices by their own partner but is fully informed about the choices by the other pair. Considering this as a...

We study a system in which N agents have to decide between two strategies θi(i ∈ 1 … N), for defection or cooperation, when interacting with other n agents (either spatial neighbors or randomly chosen ones). After each round, they update their strategy responding nonlinearly to two...
