Abstract:

We consider effect of declaration on emergence of cooperation in demographic Donor-Recipient game. Players are initially randomly distributed in square lattice of cells. In each period, players move locally to random cell in neighbors or globally to random unoccupied cell in the whole lattice, and play multiple games against local neighbors or against randomly selected global players. We restrict patters of move (play) to local or global; local (global) means with high probability the player moves (plays) locally (globally). If wealth (accumulated payoff) of player becomes negative or his age becomes greater than his lifetime, he dies. If his wealth becomes greater than some amount and there is unoccupied cell in neighbors, he has an offspring. In Donor-Recipient game, one player is selected at random as Donor and the other as Recipient. Donor has two moves Cooperate or Defect; Cooperate means Donor pays cost for Recipient to receive benefit. Defect means Donor does nothing. We introduce one option for Recipient; Recipient can declare that he is cooperative before Donor's move. We show, by Agent-Based Simulation, declaration promotes emergence of cooperation, but some players need to distinguish true declaration from false one if Donor can punish suspicious declaration.
