| Research Abstract |
The apathy of bystanders often prevails when instances of hidden crime, extortion and bulling occur in communities such as schools, prisons, the military and business work areas. The present study, the first economic analysis of the apathetic behavior of bystanders as we are aware of, models non-good Samaritan behavior as a non-cooperative game and attempts to verify this theory through experiments. The major conclusion that we have reached is that bystanders' reporting activities (good Samaritan behavior) generally increase as the number of citizens in a community decrease. If the number of students in a classroom- or prisoners in a jail- decreases from 40 members to 20 members, the good Samaritan behavior increases by 21% in our experimental cases on average.
