Abstract: Most psychology literature claims that people in need of help will be helped later if there are many potential helpers than if there are few. This phenomenon is called the bystander effect. However, psychologists base this result in experiments where the situation can be ambiguous and therefore where the need of help may not be clear. This paper develops a model and performs an economic lab experiment to study helping behavior and group size in non-ambiguous situations. Setting a simple game and using an adaptation of the Fehr and Schmidt's (1999) utility function of inequality aversion, the model predicts that the bystander effect happens when agents are homogeneous. However, when there are two types of agents the model concludes that, for small groups, more potential helpers imply that victims receive help earlier. The experimental results are in line with the results of the heterogeneous agents' model for small groups.
