This paper examines the wage implications of temporary migration for two cohorts of Italian Ph.D.s. Special attention is given to the duration of the international experience, its contribution to earned wages and the selectivity of returnees. Returnees are found to be positively self-selected and, after controlling for the endogeneity of both the migration decision and the length of stay abroad, we find positive returns for those who stay longer and negative returns for those who come back sooner. The results are confirmed in several robustness and sensitivity checks.
