Asylum Applications and Migration Flows
利用联合国难民署的年度双边庇护申请数据，分析移民的成因，发现庇护申请仅占OECD国家移民流动的十分之一，欧盟接收最多但接受率低，而来源国历史趋势的正向偏差会提高接受率。
We discuss an underutilized dataset to examine the causes of migration. The United Nations High Commissioner for Refugees publishes annual binational asylum applications and the resulting decisions. Asylum is granted to protect individuals from persecution. They are a small part of overall migration patterns: one-tenth of overall migration flows into OECD countries. The European Union receives the largest share of asylum applicants and has a low acceptance rate, but the rate increases when source countries have positive deviations from historic trends. Countries outside the EU and OECD receive almost all of the applications from neighbors with a contiguous land border.
