Subsidized primary care and community health worker (CHW) visits are important demand side policies in the effort to achieve universal health care for children under five. Causal evidence on the effects of these policies, alone and in interaction, is still sparse. This paper reports the effects...

Adaptive sampling in experiments with multiple waves can improve learning for "policy choice problems" where the goal is to select the optimal intervention or treatment among several options. This paper uses a real-world policy choice problem to demonstrate the advantages of adaptive sampling...

In many low- and middle-income countries, health coverage has improved dramatically in the last two decades, but health outcomes have not. As such, effective coverage -- a measure of service delivery that meets a minimum standard of quality -- remains unacceptably low. This Policy Research...

Pre-Analysis Plans (PAPs) for randomized evaluations are becoming increasingly common in Economics, but their definition remains unclear and their practical applications therefore vary widely. Based on our collective experiences as researchers and editors, we articulate a set of principles for...

Multiple price lists are a convenient tool to elicit willingness to pay in surveys and experiments, but choice patterns such as "multiple switching” and “never switching” indicate higherror rates. Existing measurement approaches often do not provide accurate standard errors and cannot...

Can information about the value of diagnostic tests improve provider practice and help patients recognize higher quality of care In a randomized experiment at public clinics in Mali, health providers and patients received tailored information about the importance of rapid diagnostic tests (RDTs)...

Can information about the value of diagnostic tests improve provider practice and help patients recognize higher quality of care? In a randomized experiment at public clinics in Mali, health providers and patients received tailored information about the importance of rapid diagnostic tests...

Using in-home health records for 1,763 children in Mali, this paper examines gender differences in the uptake and duration of treatment with antibiotics. The detailed data provide a window into parents’ day-to-day decisions while accounting for symptoms. There are no gender differences in...

The use of randomized controlled trials (RCTs) in the social sciences has greatly expanded, resulting in newly abundant, high-quality data that can be reused to perform methods research in program evaluation, to systematize evidence for policymakers, and for replication and training purposes....
