What links between the evaluation models for RMI and the policy decisions?[L'évaluation du RMI : la simplification de la démarche et ses enjeux]

This paper analyses the different evaluation programs which have been conducted since the beginning of the minimum income policy in 1989. It's aimed at interpreting the links between the evaluation models and the policies. Two approaches can be highlighted; the first one, that we can all "pluralistic approach" started with the early works of the national evaluation committee until the mid-90's and combined many purposes and procedures. Despite the extensive knowledge gained about the problems of poverty, it led to very few public decisions. The second approach initiated in the mid-90's resulted from the rising cost of the policy of minimum income due to the increasing number of beneficiaries. By focusing on simple indicators of efficiency and using econometric methods, the analysis appears more restrictive but it led to policy decisions which deeply modified the minimum income policy.
