Self-Insurance Wealth Substitution
Observational StudyReview
As household per-capita income increases, smallholders rely on accumulated savings and informal self-insurance mechanisms rather than commercial microinsurance, resulting in a negative relationship between income levels and formal index insurance purchase decisions.
Picture this
Imagine two neighbors living near a river: one has a large emergency bank account while the other has no savings. The wealthier neighbor skips buying flood insurance because they can absorb minor damage using their own savings, whereas poorer neighbors rely on formal insurance when available.
What the evidence says
Income per household member is negatively and significantly correlated with actual insurance uptake (probit marginal effect = -0.0000208, p < 0.10), controlling for vouchers and asset holdings.
- Who was studied
- N = 442 rural households in treatment primary cooperative villages across Amhara, Ethiopia.
- How
- Probit regression with Kebele-fixed effects analyzing demographic and economic predictors of actual index insurance purchases.
What to do
Tailor formal microinsurance marketing toward middle-tier income households that face severe vulnerability to catastrophic shocks but lack sufficient self-insurance reserves.
From the source
"Among economic variables the per capita income is negatively correlated with uptake, indicating perhaps that wealthier households do not need WII."
