No calm after the storm—diaspora influence on bilateral emergency aid flows

Abstract: This study analyzes how migrants affect their host country’s foreign policy toward their home country by measuring their influence on bilateral emergency aid. I develop the argument that besides political lobbying and the targeting of aid by the donor country, migrants affect emergency aid by providing a linkage between the countries and increasing the salience of a disaster abroad. The empirical analysis shows that the location and size of a country’s diaspora is an important predictor of emergency aid flows after natural disasters. Interaction effects provide support for the linkage argument: while the diaspora effect does not increase with the host country’s level of democracy, it is strongest with the least severe and most distant disasters.
