Short-Run Agricultural Factor Inelasticity
RCTClinical Trial
Smallholder farmers face rigid short-run physical constraints on total land acreage and capital access, preventing overall expansion of farming scale when risk parameters improve.
Picture this
Think of having a fixed-size suitcase on a trip; buying luggage insurance does not make the suitcase any bigger, but it allows you to swap out cheap bulky clothes for high-value delicate outfits.
What the evidence says
Insurance provision had no statistically significant effect on total land under cultivation (point estimate 0.029, p > 0.10) or total market value of all agricultural inputs used (point estimate 0.082, p > 0.10), acting entirely through compositional reallocation toward cash crops.
- Who was studied
- N = 1,479 smallholder farming households in Andhra Pradesh, India.
- How
- Econometric evaluation (Tobit and Probit models) comparing total land sown and total input expenditures versus cash-crop-specific allocations between insurance treatment and control groups.
What to do
Evaluate agricultural risk interventions based on intra-portfolio input reallocation rather than expecting immediate expansion of total land under cultivation.
From the source
"We find that insurance provision has little effect on total agricultural investments, but causes significant shifts in the composition of those investments."
