Instrumental Variables and Omitted Migrant Flows: Immigration and Emigration in Peru

Abstract: Instrumental variables are often used to identify the causal effect of immigration on labor market outcomes of natives. In this paper, I investigate the sensitivity of 2SLS estimators in the (common) case where a simultaneous shock occurs to the unit of interest and we do not explicitly account for it. For this purpose, I estimate the effects of both the Venezuelan immigration shock and the Peruvian emigration during the last decades on the labor market outcomes of Peruvian native stayers. Using shift-share instruments, I document positive effects of both immigration and emigration on employment rates, household income, and household expenditure (with emigration effects being about eight times larger). Reassuringly for the literature, even in a context of instruments correlated with the omitted flow the point estimates are shown to be robust to the inclusion of the omitted variable.
