L'évaluation de l'impact des politiques du travail ou concernant le capital humain se base normalement sur des enquêtes menées directement auprès des individus ayant bénéficié des dispositifs d'aides. Pour estimer leur impact net il faut en plus observer des individus non traités mais très homogènes par rapport au groupe principal. Le coût élevé de réalisation des enquêtes empêche d'augmenter la taille des échantillons et il est alors difficile de pouvoir mener des comparaisons à un niveau local. L'accès à des bases de données (fiscales, administratives, de suivi) pourraient remédier à ces limites avec beaucoup d'avantages, mais la fiabilité de cette source est souvent surestimée. Dans cet article nous présentons un travail de validation d'une base de données très complexe qui enregistre les communications (COB) qui sont prévues par la loi italienne quand il y a un changement de contrat de travail. Deux sources différentes pour l'évaluation de l'impact sont comparées et discutées : la base de données des COB et une enquête plus classique.
Impact assessment of labour or human capital policies is usually based on direct surveys of treated individuals. The net impact should be estimated observing untreated individuals which are very similar to the treated group. However, the high cost of implementation does not allow to use large samples, and therefore it is difficult to carry out statistically significant comparison at the local level. The open access to databases which were created for different purposes (e.g., tax, administrative, monitoring) could overcome these limitations with many advantages, but the reliability of administrative sources is often overestimated. In this article we present a validation exercise based on data records provided by the Italian law whenever a change in an employment contract occurs, i.e. the so called compulsory communications (COB). This was done by comparing two different data sources, that is the COB database and a direct survey performed on students one year after the course.

Abstract
Impact assessment of labour or human capital policies is usually based on direct surveys of treated individuals. The net impact should be estimated observing untreated individuals which are very similar to the treated group. However, the high cost of implementation does not allow to use large samples, and therefore it is difficult to carry out statistically significant comparison at the local level. The open access to databases which were created for different purposes (e.g., tax, administrative, monitoring) could overcome these limitations with many advantages, but the reliability of administrative sources is often overestimated. In this article we present a validation exercise based on data records provided by the Italian law whenever a change in an employment contract occurs, i.e. the so called compulsory communications (COB). This was done by comparing two different data sources, that is the COB database and a direct survey performed on students one year after the course.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
