The present study models the apathetic behavior of bystanders (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 (such as the number of students in a classroom-or prisoners in a jail-) decreases. If the number of students in a classroom decreases from 40 members to 20 members, the good Samaritan behavior increases by 21% in our experimental cases on the average.}, title = {An economic analysis of non-good Samaritan behavior: theory and experiment}, year = {2000} }
