Revisiting the Health Spending‐Growth Nexus
通过元分析整合107项研究的522个估计值，发现健康支出对经济增长有显著正向影响，但文献中存在中等程度的负向出版偏倚。
ABSTRACT The relationship between health spending and economic growth is shaped by multiple transmission channels, leading to inconsistencies in the empirical literature and a lack of definitive conclusions. To address this issue, we perform a meta‐analysis encompassing 522 estimates from 107 studies that examine the effect of health spending on economic growth. Our analysis uncovers the presence of a negative publication bias of moderate magnitude in the literature. However, after accounting for both publication bias and methodological shortcomings in the primary studies, we find that health spending exerts a substantial positive effect on economic growth. Furthermore, our findings demonstrate that the reported estimates are shaped by various factors, including differences in how economic growth and health spending are measured, the characteristics of the data, publication attributes, and the inclusion of other growth‐related variables.
