The externalities of immigration policies on migration flows: the case of an asylum policy
研究双边庇护政策（安全原籍国名单）对移民流动的外部性，发现将某国列入安全名单会使其庇护申请减少29%，并产生跨国的溢出效应。
Abstract We analyze the externalities arising from a bilateral asylum policy—the list of safe origin countries—relying on a tractable model. Using self-collected monthly data, we estimate that including one origin country on the safe list of a given destination decreases asylum applications from that origin to that destination by 29 per cent. We use a counterfactual policy simulation to quantify the spillover effects occurring across origin and destination countries. Individuals from targeted origin countries move to alternative destinations. Individuals from untargeted origins divert from alternative destinations. The magnitude of the externalities depends on the size of the affected flows.
