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. |
