Une modélisation probabiliste des registres de donneurs de moelle osseuse et des banques de sang de cordon

This paper develops a probabilistic model for organ donation organizations. The two main examples are voluntary marrow donor registries and cord blood banks. The main characteristic of this system is to facilitate the graft of bone marrow or cord blood to patients. These grafts require a high degree of compatibility between donors and receivers and the efficiency of this system is not always satisfactory despite sizes of the registries. This paper gives a framework to understand the key parameters of this problem and to proceed to simulations. We consider the case without screening or the case of optimal selection. These models may be used to infer an economic evaluation of the registries and of cord blood banks. Classification JEL : I18, C70, C61
