Overall the retailers and centre management are not convinced to cooperate with each other. The basic condition for cooperation is insight in the surplus value of the cooperation and when applicable for retailers, the permission of the head office. It depends on the kind of cooperation if these aspects are present. The evaluation of the attached risks of the cooperation is influenced by the amount of trust in each other. The more trust is present, the smaller the risks are evaluated. In the field of sharing information and the collective service quality in the shopping centre are opportunities to cooperate more intensively. In the field of marketing and service quality in the stores aren't opportunities to cooperate more.
