We are the global leader in funding, producing and synthesising high-quality evidence of what works, for whom, how, why and at what cost. We believe that better and policy-relevant evidence will help make development more effective and improve people’s lives. 3ie impact evaluations 3ie-supported impact evaluations assess the difference a development intervention has made to social and economic outcomes. 3ie is committed to funding rigorous evaluations that include a theory-based design, use the most appropriate mix of methods to capture outcomes and are useful in complex development contexts.

This study performs a rigorous evaluation of the long-term impacts of rainfall insurance access and coverage on agricultural investment and outcomes, consumption and well- being proxies using a randomised controlled trial design. Main findings We find no systematic, long-term effect of insurance access or adoption on agricultural investment decisions. There is also little to no statistical difference in reported agricultural revenues and profits. This is true even though (randomly assigned) subsidies caused households that purchased insurance policies to experience greater financial income from insurance payouts than financial costs from insurance premiums. These findings suggest that the insurance products studied were not sufficient to induce farmers to adopt theoretically promising alternative investments, such as high-yielding variety crops. Demand for rainfall insurance among study households was moderate. Depending on the year and marketing treatment, between 25% and 60% of treated households elected to purchase rainfall insurance. Demand was also shallow, as the typical buyer purchased only a single policy unless offered a discount on a bundle of policies. These results are consistent with fragile prospects for voluntary private markets for rainfall risk management. Analyses of impacts on consumption and well-being proxies reveal that insurance payouts often act as a substitute for informal transfers; however, this does not translate into an impact on consumption or savings. We also see weak results on our proxies for well-being, which is consistent with the impact we see on investment and further supports our conclusion that the insurance product offered in this case had, at best, ‘moderate’ effects. Methodology Inspired by the theoretical view that risk management can improve production outcomes, as well as a substantial body of evidence suggesting that rainfall risk is important to farmers, this eight-year-long study evaluates the impact of a new financial product, rainfall index insurance, on farmer investment behaviour in Gujarat, India. The Self Employed Women’s Association, a local non-profit organisation, introduced rainfall insurance to 52 randomly selected villages in the Ahmedabad, Anand and Patan districts. A control group, consisting of 48 villages in the same districts, was not offered rainfall insurance. Within the treatment villages, information and incentives affecting insurance take-up were randomly varied at the household level. Annual household surveys measured many variables that could have been impacted by access to or adoption of rainfall index insurance. This report focuses on effects on agricultural production decisions. Specifically, we estimate the effect of each additional ii unit of insurance coverage on total area cultivated, expenditures on agricultural inputs, the fraction of cultivated land devoted to high-yielding variety crops, the fraction of cultivated land devoted to cash crops, total agricultural revenues and agricultural profits. Among the differences between this study and other research, two are especially important. First, rather than providing free insurance coverage, we examine the effects on households who are close to the margin of insurance adoption. Given scarce public funds for agricultural risk management, these are the farmers most likely to be affected by modest, broad-based subsidies. The household-level random variation helps us understand the prospects for private index rainfall insurance markets. Second, insurance is sometimes described as ‘the most misunderstood industry’, and this project’s length provides an opportunity for the measurement of impacts after farmers have had a chance to achieve a greater understanding of its ramifications. iii Contents Acknowledgements ........................................................................................................ i Summary ........................................................................................................................ ii List of figures and tables .............................................................................................. v Abbreviations and acronyms ...................................................................................... vi 1.
