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 (WTP) 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...

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 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...

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...

Consider a marriage market with continuous-time two-sided search and trans- ferable utility in which the match payo depends on age. This paper characterizes a set of payo functions consistent with two salient marriage age patterns: (1) assortative match- ing by age, and (2) \dierential age...
