Pourquoi est-il si difficile d'évaluer les politiques publiques ?. Le cas exemplaire des allègements de charges sur les bas salaires en France

The cuts in social contributions in France provide a good illustration of the difficulties in evaluating public policies. The state of technology assessment is not the most binding point of the evaluator activity. The nature and especially the pace of reforms put stronger constraint on the evaluation process. There are far away from econometric technologies that improve datas quality to their application to policies that are actually implemented by governments. Given these constraints, we say that the ?evaluability? of public policy could be a factor to consider in the implementation of reforms.
