What explains state responses to the refugees they receive? This book identifies two puzzling patterns: states open their borders to some refugee groups while blocking others (discrimination), and a number of countries have given the United Nations (UN) control of asylum procedures and refugee camps on their territory (delegation). To explain this selective exercise of sovereignty, the book develops a two-part theoretical framework in which policymakers in refugee-receiving countries weigh international and domestic concerns. Internationally, leaders use refugees to reassure allies and exert pressure on rivals. Domestically, policymakers have incentives to favor those refugee groups with whom they share an ethnic identity. When these international and domestic incentives conflict, shifting responsibility to the UN allows policymakers to placate both refugee-sending countries and domestic constituencies. The book then carries out a “three-stage, multi-level” research design in which each successive step corroborates and elaborates the findings of the preceding stage. The first stage involves statistical analysis of asylum admissions worldwide. The second stage presents two country case studies: Egypt (a country that is broadly representative of most refugee recipients) and Turkey (an outlier that has limited the geographic application of the Refugee Convention). The third stage zooms in on sub- or within-country dynamics in Kenya (home to one of the largest refugee populations in the world) through content analysis of parliamentary proceedings. Studying state responses to refugees is instructive because it can help explain why states sometimes assert, and at other times cede, their sovereignty in the face of refugee rights.
