Abstract
This study examines the effect of democracy on public health by using panel data of 188 countries over the period 1972-2019. We use various regression methods, such as pooled ordinary least squares, fixed effects, dynamic generalized method of moments (GMM), a split-sample method, and a quadratic model to address econometric issues. The pooled regression supports the positive effect on health, but it does not exist in low-income countries, which can be explained by the threshold effect. The fixed effects regression confirms the positive impact on infant mortality but not on life expectancy, which illustrates the historical and cumulative effect of democracy on life expectancy. The non-linear regression finds a U-shaped relationship between democracy and infant mortality, which is consistent with the fixed effects regression result of the positive effect on mortality in the low-income group. The dynamic GMM regression shows the expected strong relationship between previous health and current health status. Overall, the regression analysis supports the positive effect of democracy on public health.Keywords
