L'analisi di rete per capire il mercato del lavoro. I flussi di assunzione di laureati e dottori di ricerca nel Friuli Venezia Giulia nel periodo 2005-2014

In this paper we present the results of a network analysis on the mobility of the highly skilled workers in the regional labor market of Friuli Venezia Giulia. We make use of the Social Network Analysis (SNA) methods and of a new detaset on mobility of graduates and PHD’s from the Regional Universities in the period 2005-2013. The new dataset is based on three different sources: the Administrative archives of the three Universities of Friuli Venezia Giulia (graduates and PhD), the Public Labour Agency (individual hiring flows),the Bureau van Dijk (company’s data). The network analysis is performed for the period 2005-2013 and for two sub-periods separately (2005-2008 and 2009-2013) in order to disentangle the possible changes determined by the recent severe economic crisis. Results show that the hiring flows assume a scale-free network configuration, in the overall as well as in the two sub-periods, where the larger and innovative regional firms play a crucial role for the overall connectivity. However, from a micro-level perspective, in the second period emerges an increasing level of homophily, that is the workers’ mobility mostly happen within groups of similar firms (according to our classification of innovative vs traditional firms). Finally, from a methodological point of view, network analysis seems to be a promising approach to better understand labour market structure and dynamics.
