Informal Risk-Sharing Interaction with Formal Insurance
Observational StudyReview
Formal index insurance products introduced into traditional agrarian communities interact with pre-existing informal risk-sharing networks, which can either substitute for or complement formal risk hedging mechanisms.
Picture this
Imagine a neighborhood where families pool money whenever a member's house roof leaks; introducing a formal roofing insurance policy may either cause neighbors to stop helping each other or encourage the entire group to buy formal policies together to cover major severe storms that the pool cannot afford.
What the evidence says
Informal risk-sharing mechanisms efficiently handle localized, non-covariate shocks but fail to absorb spatially covariate monsoon droughts, making formal index insurance complementary rather than competitive with informal village networks.
- Who was studied
- N = 1,479 farming household heads across 45 villages in Mahbubnagar and Anantapur, Andhra Pradesh, India.
- How
- Comparative analysis referencing related randomized evaluations (e.g., Mobarak and Rosenzweig 2012) on formal insurance subsidies combined with community risk-pooling.
What to do
Distribute parametric index insurance through existing community savings groups or self-help groups (SHGs) to align formal drought protection with informal social safety nets.
From the source
"In India, Mobarak and Rosenzweig (2012) conduct a randomized evaluation which uses subsidies to induce households to purchase rainfall insurance: while their main interest is the interaction between insurance demand and informal risk-sharing, they also find evidence that insured households plant riskier varieties of rice."
