We study how social proximity between the sender and the receiver of information shapes the effectiveness of preventive health behaviour campaigns and the persistence of misinformation. We implement a field experiment among a representative sample of slum residents in two major Indian cities...

Widespread misconceptions can be critical, especially in times of crisis. Through a field experiment, we study how to address such wrong or inaccurate beliefs using messages delivered to individual citizens using mobile phones. We focus on misinformation related to the COVID-19 pandemic in a...

This paper provides novel evidence on the trade-off between public service delivery and free riding in low- and middle-income countries. We implement a field experiment in the slums of two major Indian cities, where inadequate access to sanitation restricts residents to either free ride, by...

Poorly maintained public infrastructure is common in low- and middle-income countries, with consequences for service delivery and public health. By experimentally identifying the impact of incentives for local maintenance for both providers and potential users, this paper provides one of the...

We implement a mixed method approach that combines a randomized controlled trial and qualitative data collection to assess whether, and if so how, behavioural change can be sustained. We do so in the context of Pakistan's national sanitation strategy to combat open defecation, Community-Led...

I provide evidence of the severe social costs imposed by infrastructure projects that are being implemented (i.e., projects started but not yet completed) in the context of sewerage in Peru. Using a counterfactual implementation predicted from geography-based cost considerations as an...

It is widely accepted that investing in public infrastructure promotes economic development. However, there is little awareness of the prevalence of unfinished infrastructure projects and their consequences. In this paper, I study the effect of unfinished sewerage infrastructure on early-life...

We analyse the marriage decisions of men and women in rural India, focusing on the added attractiveness of sanitation within the marital living arrangement. We demonstrate that the Government's Total Sanitation Campaign (TSC) changed marriage market outcomes for both men and women. To decompose...

We exploit novel data collected within a randomised controlled trial of a sanitation microcredit intervention to study how intra-household gender differences in perceptions of costs and benefits of sanitation impact investment decisions. We show that - as long as the wife is involved in...

Imperfect capital markets and commitment problems impede lumpy human capital investments. Labelled loans can alleviate both constraints, but little is known about their effectiveness in practice. We draw on a cluster randomized controlled trial in rural India to provide the first evidence that...
