We provide a consistent empirical framework to estimate the net joint effect of emigration and remittances on the migrants’ countries of origin key economic variables (GDP growth and labor force participation), while addressing the endogeneity concerns using novel “shift-share” instrumental variables in the spirit of Anelli and others (2023). Understanding this joint impact is crucial for the Latin America and the Caribbean region that has seen a continuous growth in remittances over the past decades, due to steady emigration, and where remittances represent the largest capital inflows for many countries now. Focusing on the past two decades (1999-2019), this study finds that on average emigration has a negative and statistically significant impact on contemporaneous economic growth and change in labor force participation in the countries of origin across LAC, while remittances partially mitigate this adverse impact—especially on economic growth—resulting in a small negative net joint effect. There are significant differences across subregions for all estimates, with the largest negative effects observed in the Caribbean. In addition, the negative impact of emigration and remittances on the change in labor participation is small, but for the youngest cohort (15-24) is twice as large as for the overall labor force participation. The results are robust to various specifications, variables, and measurements of emigration and remittances.
