Is there an ex-ante moral hazard on Indonesia's health insurance? An impact analysis on household waste management behavior.

The presence of ex-ante moral hazard could undermine the potential gain from expanding health insurance coverage in developing nations. To test the proposition, this study utilizes a nationally representative longitudinal survey with Indonesia's health insurance for poor policy in 2014 as the quasi-experimental case study. The country represents developing nations that undergo a massive and rapid expansion of health insurance coverage. The empirical approach combines a matching and difference-in-differences method to obviate potential bias of the selectivity nature of health insurance provision and time-invariant unobserved factors. The findings suggest the presence of ex-ante moral hazard in the form of the less people using trash cans associated with the introduction of the subsidized health insurance premium. The results add empirical findings of a negative side effect of expanding health insurance coverage in developing nations. [ABSTRACT FROM AUTHOR]
