Replication Material for \"No Calm After the Storm -- Diaspora Influence on Bilateral Emergency Aid Flows\"

This study analyzes how migrants affect their host country's foreign policy towards 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.

本研究通过量化移民对双边紧急援助的影响效应，剖析移民如何作用于其居住国针对其母国的外交政策。本研究提出如下论点：除政治游说与援助捐赠国的援助定向分配外，移民还可通过搭建两国间的沟通纽带，并提升海外灾害事件的议题显著性，进而影响双边紧急援助的流动。实证分析结果表明，一国侨民社群（diaspora）的分布区位与群体规模，是自然灾害发生后双边紧急援助流动的重要预测因子。交互效应的检验结果为上述纽带假说提供了实证支撑：尽管侨民社群的影响效应并未随居住国的民主发展水平提升而增强，但在灾害强度最低、地理距离最为遥远的灾害情境中，其影响效应最为显著。
