Abstract: |
We consider an
interaction between a donor and a recipient where the actions of a donor produce
multiple results to the recipient. There are Optimists and Pessimists who
focus on the best and worst outcomes among them as a recipient of the
interaction, respectively, and they try to reflect on their experience in
their next action as a donor. What is the effect on the emergence of
cooperation? This paper formulates the situation as a Demographic
Multi-attribute Donor- Recipient game and introduces also Average, who focuses
on the average outcome and considers the effect of the initial distribution
of them on the emergence of cooperation by Agent-Based Simulation. If the
initial population includes only one type from Pessimist, Optimist, or
Average, then the emergence rate of cooperation increases in this order. In
particular it is very low with only the Pessimist. The emergence rate of cooperation
in case of initial populations including both Optimist and Pessimist is
larger than that of the initial population including only the Optimist. Thus
the Optimist is crucial for a high emergence rate of cooperation in realistic
initial populations including the Pessimist. |
