Political decentralisation and the spatial distribution of infant mortality in less developed nations
研究了政治分权如何影响欠发达国家婴儿死亡率的水平与空间分布，发现分权在富国降低死亡率，但在穷国加剧了地区间不平等，并以洪水事件和巴西案例验证了机制。
This paper focuses on political decentralisation as an institutional determinant of the level and spatial distribution of infant mortality rates (IMR). At the national level, we show that political decentralisation is linked to lower IMR, but these benefits are concentrated in high-income decentralised nations. In developing nations, decentralisation is associated with significantly higher spatial variation in IMR. We explore the mechanisms driving these patterns by leveraging floods as plausibly exogenous events in our global sample and a detailed analysis of Brazil. In Brazil, floods increase municipal variation in IMR, with impacts disproportionately accruing in low-income municipalities with limited government services.
