"Active labor market policies are massively used with the objective being to improve labor market outcomes of individuals out of work. Many observational evaluation studies have been published. In this review, we critically assess policy effectiveness. We emphasize insights from recent randomized controlled trials. In addition, we examine policy effects that have not been the primary object of most of the past evaluations, such as anticipatory effects of advance knowledge of future treatments and equilibrium effects, and we discuss the actual implementation of policies. We discuss the importance of heterogeneity of programs and effects and examine the extent to which potential participants are interested in enrollment. We also discuss the assessment of costs and benefits of programs."

"En moyenne, les salaires augmentent avec l'âge, mais est-ce que des salaires plus élevés correspondent à une productivité plus élevée ? Les auteurs du présent article tentent de répondre à cette question. Leur étude suggère que la productivité des salariés croît avec l'âge jusqu'à 40 ans, avant de se stabiliser. En particulier, il n'apparaît pas d'écart marquant entre salaire et productivité, si ce n'est aux âges les plus avancés (plus de 55 ans). Ces résultats restent néanmoins assez peu précis, car l'estimation contient au moins deux biais : les salariés âgés sont plus nombreux dans les entreprises anciennes et peu efficaces et ils représentent une partie de la main-d'œuvre qui s'ajuste moins rapidement aux chocs de productivité."

"This paper implements a method to identify and estimate treatment effects in a dynamic setting where treatments may occur at any point in time. By relating the standard matching approach to the timing-of-events approach, it demonstrates that effects of the treatment on the treated at a given date can be identified even though non-treated may be treated later in time. The approach builds on a "no anticipation" assumption and the assumption of conditional independence between the duration until treatment and the counterfactual durations until exit. To illustrate the approach, the paper studies the effect of training for unemployed workers in France, using a rich register data set. Training has little impact on unemployment duration. The contamination of the standard matching estimator due to later entries into treatment is large if the treatment probability is high. "
