Comparing Over-Education for Natives, Migrants and Second Generations in Italy and Assessing the Role of Networks in Generating It.” Italian Economic Journal 9 (1): 175–97. 2023.https://doi.org/10.1007/s40797-022-00184-5https://hdl.handle.net/20.500.14490/397Whilst migration has become a structural feature of most European countries, the integration of foreigners in the labour market continues to raise concerns. Evidence across countries shows that migrants are more often over-educated than natives. Over the last few years, scholarship has intended to capture the effect of informal networks on migrants’ over-education. Interestingly, no study has looked into the Italian case, a country for which the effect of networks on education-occupation mismatch is well documented. This article has two objectives: it assesses the extent to which over-education affects migrants and it evaluates the role informal networks play in producing it. We find that migrants have a higher probability of being over-educated than natives and second-generation migrants. Likewise, we find little evidence of a differentiated effect of networks as they tend to increase migrants’ over-education whilst decreasing it for natives and second-generation migrants. Empirical evidence is drawn from the application of causal inference modelling to PLUS 2018—Participation, Labour, Unemployment Survey.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Informal networksOver-educationMigrantsSecond-generation migrantsLabour marketPropensity score matchingInverse probability weightingArticle
