Disasters and social vulnerability determinants of federal subsidiarity assistance
研究了美国联邦政府向州政府提供的辅助援助（包括短期和长期公共援助拨款及政府间转移支付）的决定因素，发现灾害触发短期和长期援助，而社会脆弱性更能解释政府间转移支付。
Abstract Subsidiarity assistance creates opportunities for the federal government to intervene in subnational affairs, supplement emergency response, and reduce jurisdictional vulnerabilities. Recognizing the differential effects that disaster events and revenue sharing could have on states, the research investigates the determinants of federal subsidiarity assistance grants to states in the context of American federalism. This study draws from disaster impact scholarship and social vulnerability theory for theoretical context to understand the determinants of short‐term and long‐term public assistance grants and intergovernmental transfers, which constitute federal subsidiarity assistance to subnational governments. Using panel data on 50 U.S. states over a 17‐year time period, findings show that disasters trigger federal subsidiarity assistance for disaster‐induced short‐term and long‐term public assistance grants; however, social vulnerability more likely explains intergovernmental transfers to states.
