Risk sharing and public transfers
利用埃塞俄比亚农村的粮食援助公共转移数据，检验村庄层面的风险分担安排，发现完全风险分担被拒绝，但存在部分风险分担，且粮食援助可能挤出了非正式保险。
We use public transfers in the form of food aid to test for the presence of risk sharing arrangements at the village level in rural Ethiopia. We reject perfect risk‐sharing, but find evidence of partial risk‐sharing via transfers. There is also evidence consistent with crowding out of informal insurance linked to food aid programmes.
