Does Insurance Improve Resilience? Research: Jennifer Denno Cissé Presented by: Joanna Upton Academic Workshop on Mobile Pastoralism, Index Insurance, Computational Sustainability and Policy Innovations for the ASALs of East Africa June 10, 2015
Outline Background on Development Resilience Data Insurance and Household Resilience Insurance and Aggregate Resilience Conclusion Intro/BackgroundDataIdentificationAggregationConclusion Introduction
Barrett & Constas (2014) Proposes a theoretical framework for “development resilience” Implications for measurement: Recommends a moments-based, probabilistic approach Intro/BackgroundDataIdentificationAggregationConclusion Development Resilience
Cissé & Barrett (in production) Empirical implementation of B&C theory of development resilience Builds on poverty measurement, poverty dynamics, poverty traps, and vulnerability literatures Resilient = a high probability of maintaining acceptable level of well- being Intro/BackgroundDataIdentificationAggregationConclusion Development Resilience
Insurance & Resilience Use a development resilience approach to evaluate impact of IBLI on well-being Explore household-level impacts of insurance Construct aggregable FGT-type measure to explore resilience by subgroup Intro/BackgroundDataIdentificationAggregationConclusion Contribution
Data Intro/BackgroundDataIdentificationAggregationConclusion IBLI 5 rounds of panel data (Marsabit) 800+ households HH demographics, livestock accounting, income, consumption 2011 drought (before R3)
Data Intro/BackgroundDataIdentificationAggregationConclusion Constructed Variable Shock (drought dummy) = 1 if predicted livestock mortality > 15% Instrumental Variables Insurance Coupon Coupon * Predicted Livestock
Data Intro/BackgroundDataIdentificationAggregationConclusion Outcome Variables Mid-Upper Arm Circumference (MUAC) in cm Tropical Livestock Units (TLU): 1 TLU = 1 cow, 0.7 camel, 10 sheep, or 10 goats

Negative impact of shock on resilience.Combining mean & variance allows us to see positive impact of insurance on resilience, even in non-shock years. Having insurance during a drought years further increase TLU resilience (not significant for MUAC).
