Abstract

This study examines the impact of private ownership of water and wastewater systems on disease reduction linked to sanitation in Brazil from 1998 to 2021. It updates Saiani and de Azevedo (2018), which analyzed the period 1995–2008, by incorporating over a decade of additional data, key policy changes such as the 2020 Sanitation Law, and employing the Callaway–Sant’Anna Staggered DID methodology to address heterogeneity in treatment effects. Our findings reveal mixed results: while some municipalities achieved reductions in morbidity rates, others showed no change or increases, underscoring the context-dependent nature of privatization outcomes. A notable example is the case of Tocantins, where transitioning from a hybrid private-state model to full private ownership led to a significant decrease in disease morbidity, particularly among the most affected age groups. These advancements provide a robust, updated perspective on the privatization debate, offering valuable implications for policy and practice.
水和废水系统的私有制:评估健康影响
本研究考察了1998年至2021年巴西水和废水系统私有制对减少与卫生有关的疾病的影响。它更新了Saiani和de Azevedo(2018)对1995-2008年期间的分析,纳入了十多年的额外数据、2020年《卫生法》等关键政策变化,并采用Callaway-Sant 'Anna交错DID方法来解决治疗效果的异质性。我们的研究结果显示了不同的结果:虽然一些城市的发病率有所下降,但其他城市的发病率没有变化或增加,这强调了私有化结果的环境依赖性。一个显著的例子是托坎廷斯,在那里,从公私混合模式过渡到完全私有制导致疾病发病率显著下降,特别是在受影响最严重的年龄组中。这些进展为私有化辩论提供了一个强有力的、最新的视角,为政策和实践提供了宝贵的启示。
