Empirics of health-aid, education and infant mortality: a semiparametric study

The present article uses semiparametric regression to capture the impact of foreign-aid given for health purposes on the Infant Mortality Rate (IMR) of poor developing countries, after controlling for other covariates. We also investigate whether education (general awareness) helps lower IMR directly or helps improve effectiveness of health-aid in reducing IMR. In addition, the study investigates whether various disaggregated components of health-aid (for example, aid that goes for infectious disease control or nutrition) help lower IMR. We find that although adult education (awareness) always lowers IMR, the overall effect of health-aid remains insignificant. Our conclusion is robust to various disaggregated components of health-aid as well. We also check if health-aid has improved prenatal care for expecting mothers but our conclusion regarding the overall ineffectiveness of aid remains unchanged. Interestingly, we find that total health-aid as well as nutrition aid may lower IMR only after education exceeds a threshold level - a new angle that has not been explicitly explored before. We also find interesting role of education in making the aid more effective for prenatal care. Our semiparametric nonlinear estimation strategy helps us unravel certain interesting thresholds and facts which cannot be captured in a linear parametric estimation framework.
