As conclus??es do trabalho foram: 1) o efeito doa????o ocorreu para executivos financeiros e m??dicos; 2) o efeito disposi????o afetou somente os estudantes universit??rios; 3) o medo do arrependimento influenciou as decis??es dos estudantes de MBA e executivos e 4) a abordagem modificou a decis??o dos m??dicos e dos estudantes de MBA e universit??rios.
