Wealth-Independent Insurance-Induced Risk-Taking
RCTClinical Trial
Standard microeconomic theory often predicts that wealthier households, possessing greater informal risk-coping capacity or lower absolute risk aversion, will respond differently to formal insurance provision than poorer, liquidity-constrained households.
Picture this
Imagine offering free safety helmets to both wealthy and low-income bicycle riders; both groups increase their riding speed by roughly the same amount because the physical protection of the helmet works identically regardless of how much money is in the rider's bank account.
What the evidence says
Interacting the insurance treatment with landholdings or the principal component wealth index yielded statistically insignificant interaction coefficients for cash crop investment probability, cash crop expenditure, and cash crop cultivated area [1, 2].
- Who was studied
- N = 1,479 farming household heads across 45 villages in Andhra Pradesh, India.
- How
- Randomized Controlled Trial (RCT) evaluating interaction effects between insurance treatment assignment and baseline wealth measures (acres of land owned and a principal component wealth index).
What to do
Design retail agricultural index insurance programs without wealth-targeted stratification, as smallholder production responses to risk reduction operate independently of baseline asset levels [2, 3].
