我们研究了正式指数保险产品的引入如何影响埃塞俄比亚南部牧民之间的非正式风险分担。通过使用详细的社交网络数据、购买保险产品的随机激励以及反映现有习惯安排的假设非正式转移数据，我们发现受访者自己的正式保险摄取对他们通过习惯机构分担风险的意愿没有显著影响。我们还发现弱证据表明，随机匹配的同行的保险摄取积极影响受访者的意愿，使非正式转让的比赛。总的来说，我们的研究结果表明，在这种情况下，指数保险并没有排挤由社交网络介导的非正式风险分担。
We study how the introduction of a formal index insurance product affects informal risk‐sharing among pastoralists in southern Ethiopia. Using detailed social networks data, randomized incentives to purchase the insurance product, and hypothetical informal transfer data that mirror the existing customary arrangements, we find respondents’ own formal insurance uptake has no significant effect on their willingness to share risk through customary institutions. We also find weak evidence that a randomly matched peer's insurance uptake positively influences respondents’ willingness to make informal transfers to that match. Overall, our results imply that in this context index insurance does not crowd out informal risk‐sharing mediated by social networks.
