Heterogeneity in Long Term Health Outcomes of Migrants within Italy
NBER Working Paper No. 19422
This article examines the long term physical and mental health effects of internal migration focusing on a relatively unique migration experience from Southern and Northeastern regions of Italy to Northwestern regions and to the region around Rome concentrated over a relatively short period from 1950-1970. OLS regression estimates show significant evidence of a migration effect among early-cohort females on physical health. We find no evidence of migration-health effects for the later cohort, nor for males in the early cohort. We use finite mixture models to further explore the possibility of heterogeneous effects and find that there is a significant and substantial improvement in physical and mental health for a fraction of migrant females in the early cohort but not for others. Analysis of the group for which effects are significant suggest that health effects are concentrated among rural females in the early cohort.
