We evaluate the ALMP’s with a particular attention to the differentiation of impacts by categories of programmes and categories of beneficiaries. These two forms of heterogeneity can in fact lead to erroneous evaluations or too partial:i) The heterogeneity of programmes proposed, in particular their characteristics (type of contract, duration, remuneration, training, etc.) are an important source of complexity in behavior of self-selection of job seekers: behaviors can be multiples and strategic.ii) The heterogeneity of target-populations (low-skilled, youth, women, priority category, first-job seekers, etc.) is an important source of complexity in the behavior selection of employment advisor.There is finally no reason that different types of programmes have the same average effect on various public as well. We evaluate so ALMP’s on multiple criteria of effectiveness (heterogeneity of criteria).
