This paper summarizes the literature on the impact of state subsidized or social health insurance schemes that have been offered, mostly on a voluntary basis, to the informal sector in low- and middle-income countries. A substantial number of papers provide estimations of average treatment on the treated effect for insured persons. The authors summarize papers that correct for the problem of self-selection into insurance and papers that estimate the average intention to treat effect.
