ABSTRACT: The objective of this study is to evaluate the effects of major, minor, and moderate changes in public health expenditures on health outcomes in the Comoros. Quarterly data series from 1990Q1 to 2020Q4, obtained from the World Development Indicators (WDI, 2023), were used for the empirical analysis. The estimates show that MTNARDL model provides more robust results than NARDL model. Similarly, the results of this improved framework indicate that the effects of extremely large changes in public health expenditures on health outcomes differ significantly from the effects of extremely small changes. Once again, the results reveal that the positive impacts of health expenditures on health outcomes diminish at the lowest thresholds. Furthermore, the asymmetric effects between health expenditures and outcomes are more pronounced in the long term than in the short term. Therefore, to ensure moderate rates of infant and adult mortality and an increase in life expectancy at birth in the Comoros, policymakers should pay adequate attention to long-term dynamics and ensure that the level of public health expenditure does not trend towards lower thresholds where the positive impacts of health expenditures fade.
