This paper provides new evidence on the recent performance of piped water consumption subsidies in terms of pro-poor targeting for 10 low- and middle-income countries around the world. Our results suggest that in these countries, existing tariff structures fall well short of recovering the costs of service provision, and that, moreover, the resulting subsidies largely fail to achieve the goal of improving the accessibility and affordability of piped water among the poor.

This paper provides new evidence on how effectively piped water consumption subsidies are targeting poor households in 10 low- and middle-income countries around the world.

This paper estimates flexible child health production functions to investigate whether better water, sanitation and hygiene (WASH) practices make nutrition intake more productive for children aged 6-24 months.

In November 2018, Nigeria declared that its water supply, sanitation and hygiene sector was in crisis. This was partly prompted by the fact that the country has struggled to make progress towards ending open defecation. Almost one in four Nigerians – around 50 million people – defecates in open areas.

We study the effectiveness of a community-level information intervention aimed at reducing open defecation (OD) and increasing sanitation investments in Nigeria. The results of a cluster-randomized control trial conducted in 247 communities between 2014 and 2018 suggest that average impacts are exiguous.

We study the effectiveness of a community-level information and mobilization intervention to reduce open defecation (OD) and increase sanitation investments in Nigeria. The results of a cluster-randomized control trial in 246 communities, conducted between 2014 and 2018, suggest that average impacts are exiguous.

This paper, written collaboratively by IFS researchers and policy-makers from Ethiopia and Ghana, has multiple and interlinked objectives: (i) to provide an overview of tax incentives and best practices for their design grounded in economic principles, and assess how these apply to the case studies of Ethiopia and Ghana; and (ii) to understand more broadly the causal impacts of tax incentives on economic outcomes in developing countries by reviewing the relevant methodologies to conduct rigorous quantitative analysis and the existing empirical literature. Finally, we discuss the policy implications and avenues for research given the existing literature on the causal impact of tax incentives.
