Social health insurance for the poor: Targeting and impact of Indonesia's Askeskin programme

► We assess targeting and impact of a subsidized social health insurance for the informal sector and the poor in Indonesia. ► We find that the programme is indeed targeted to the poor and those most vulnerable to catastrophic OOP health spending. ► Social health insurance has improved access to health care as it increased utilization of outpatient care among the poor. ► The programme has slightly increased OOP health spending due to an increase of relatively more expensive care.
