Abstract: Discrimination against foreign applicants was studied using an in-basket exercise with 210 Swiss managers. Participants had to evaluate and select Swiss (in-group) or Kosovo-Albanian (out-group) candidates. Results showed that supervisor advice to prefer in-group members reduced out-group member's chances to be selected for an interview. However, codes of conduct stressing the importance of equal opportunities, codes enforcement, and the level of cognitive moral development of participants had no impact on such decisions. Implications for both research and organizations are presented --- Old month value: Juin
