Léa MARCHAL, Claire NAIDITCH, Betül SIMSEK, Managing Migration Flows Through Foreign Aid – R&R.
Abstract: This paper investigates through which channels foreign aid impacts migration to donor countries. To disentangle the non-donor-specific channels (development and credit constraint channels) from the donor-specific channels (information and instrumentation channels), we use the fact that multilateral aid is not donor-specific contrary to bilateral aid. We estimate a gravity model derived from a RUM model of migration using an IV-2SLS strategy and the DEMIG-C2C and AidData datasets. We find that aid donated by a country increases migration to that donor through an information channel and especially for the poorest recipient countries. In addition, we find that aid weakly reduces migration to any country via a development channel.

Jerg GUTMANN, Léa MARCHAL, Betül SIMSEK, Do rights matter in migration decisions? Inference based on gender differences – In progress.
Abstract: This article studies the role of institutions as a driver of international migration. We exploit the differential effect of discriminatory legal institutions with respect to the largest population experiencing such systematic discrimination — women — on individual migration decisions. We estimate the migration rate of females with respect to males using a gravity model derived from a RUM model of migration. Using data on 107 origin to 26 destination countries over 1960-2011 and an instrumentation strategy, we find that gender discrimination depresses the relative migration rate. Relative migration increases with equality in political rights and civil liberties in low-income countries, while it increases with economic rights in middle- and high-income countries.
