Abstract
Compulsory Communications system data contain important and so far under-investigated information on employment dynamics in Italy. They record all the activations, transformations, fixed-term extensions and anticipated terminations of employment relationships between any worker and employer since the beginning of 2008. Aim of this note is to exploit this recent database and provide useful up-to-date measures of job dynamics in the Italian labour market. In particular, transition probabilities among different types of contracts are estimated, thus detecting the main determinants of the probability of job activation and job anticipated termination.
