In Simple Words
Imagine a health insurance policy meant to encourage sedentary people to start extreme mountain climbing. The primary buyers end up being experienced climbers who scale mountains every weekend and want protection for financial risks already incurred.
Farm households offered insurance
- Not using chemical fertilizer
- Comparison group
- Already using chemical fertilizer
- More likely to buy insurance
Observed association, not an effect of assigning fertilizer. Insurance was designed to protect input spending; increased input use was not demonstrated.

Weather index insurance is theorized to enable low-input farmers to adopt risky agricultural technologies, but in practice adoption is highest among farmers who already use high input levels. Insurance serves a protective function for existing input users rather than driving new technology adoption.
Participants
N = 440 rural smallholder households across sales-active Kebeles in Amhara, Ethiopia.
Study Design
Instrumental variable production function estimation of factor marginal products linked to probit models of insurance purchase, sum insured, and own-cash outlay.
Results
Marginal product of inputs negatively predicts actual insurance purchase in interlinked villages (coefficient = -0.0221, p < 0.01), sum insured (coefficient = -30.91, p < 0.01), and own cash spent (coefficient = -1.050, p < 0.01). Chemical fertilizer use positively predicts uptake (coefficient = +0.177, p < 0.05).
Takeaway
Target weather index insurance sales campaigns toward farmers with existing high input expenditures to safeguard current investments before expecting insurance to drive adoption among non-users.
