This study examines the effects of cross-border return migration on intertemporal and intergenerational transmission of socio-economic status across six new harmonized surveys from three Arab countries: Egypt (1998, 2006, 2012), Jordan (2010, 2016) and Tunisia (2014). We link individuals’ current outcomes to those in prior years and to their parents’ outcomes. We first isolate the outcomes of interest – income, employment status, household wealth based on both productive and non-productive assets, and residence status. Next, we evaluate individuals’ socioeconomic mobility over time and across generations as a function of their migration histories. Return migrants, current migrants, and (yet) non-migrants are distinguished. Transitions in individuals’ outcomes across years and generations are made functions of pre-existing socioeconomic status, demographics and migration status.
