We test a two-stage compensation mechanism for promoting cooperation in Prisoner’s Dilemma games. Players first simultaneously choose binding non-negative amounts to pay their counterparts for cooperating, and then play the induced game knowing these amounts. In our games, all payment pairs consistent with mutual cooperation in subgame-perfect equilibrium transform these games into coordination...

Cooperation is pervasive and constitutes the core behavioral principle of human social life. Previous studies have revealed that mutual cooperation was reliably correlated with two reward-related brain regions, the ventral striatum and the orbitofrontal cortex. Using functional magnetic resonance imaging (fMRI), this study sought to investigate how the loss and gain contexts modulated the neura...

The paper aims to extend the findings of a previous study (Grinberg et al., 2012) exploring the impact of social relations on the cooperation in the Prisoner’s dilemma game. Relations between players are manipulated by assigning different roles. The roles embodied the four basic types of human relations in line with Fiske’s relational models theory (Fiske, 1991): communal sharing, authority ran...

Believing mutually is one important premise to ensure that cooperation among multiple agents goes smoothly. However, mutual belief among agents is always considered for granted. In this paper, we adapt a method based on the position-exchange principle (PEP) to reason about mutual belief among agents before cooperation starts. By reasoning about mutual belief among agents, we can judge whether c...
