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...

Overuse of medical care is often attributed to an informed expert problem, whereby doctors induce patients to purchase unnecessary treatments. Alternatively, patients may drive overuse of medications by exerting pressure on doctors to overprescribe, undermining the doctor's gatekeeping function...

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 high error rates. Existing measurement approaches often do not provide accurate standard errors and cannot correct...

In many low- and middle-income countries, health coverage has improved dramatically in the past 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. Improving Effective Coverage 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....

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...

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)...
