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...

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...

This study explores the interaction between the quality of public services, the implementation of user fees, and the resulting potential for exclusion, that can lead to negative externalities. Our theoretical framework takes account of the possible externalities that result from excluded users...

Imperfect capital markets and commitment problems impede lumpy human capital investments. Labeled loans have been postulated as a potential solution to both constraints, but little is known about the role of the label in influencing investment choices in practice. We draw on a cluster randomized...

We exploit novel data collected within a randomized 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...

This report provides a description of the first wave of household data collected for a randomised field experiment in Bosnia. The study intends to measure the impact of microcredit on poverty reduction among Bosnian households and the development of small enterprises that may otherwise not have...

This report uses data on food and non-alcoholic drink purchases from shops, takeaways, restaurants and other outlets to analyse how the diets of a large, representative panel of households in Great Britain evolved 15 months before and up to 24 months after the start of the onset of the COVID-19...

We study how social proximity between the sender and the receiver of information shapes the effectiveness of preventive health campaigns. Focusing on shared religious affiliation as a signal of proximity, we implemented a field experiment during the initial phase of the COVID-19 pandemic in two...

We use an RCT to analyse the impact of microcredit on poverty reduction in Bosnia. The study population are loan applicants that would normally have just been rejected based on regular screening. We find that access to credit allowed borrowers to start and expand small-scale businesses....

This study evaluates an intervention in the dairy subsector by an Indian livelihood promotion institution and conducts a detailed analysis of the main cost and benefit factors of the activity. Two rounds of data are available which allows for the comparison of impacts and costs and benefits...
