Drawing on several years of original research as well as other evidence from the field, the ILO’s Microinsurance Innovation Facility and the MicroInsurance Centre’s Microinsurance Learning and Knowledge (MILK) project provide concrete insights into how, when, in what ways, and to what extent clients receive value from microinsurance. This first of three briefs on client value introduces the theory of change through which value is realized and presents the evidence of impact in terms of improved financial protection, reduced vulnerability, and better health.
