"Using a two-level randomized experiment covering 5 million people in Burkina Faso, we examine the impact on family planning knowledge and behavior of both general exposure to mass media (800 women receive radios in status quo areas) and an intensive evidence-based family planning campaign (8 of 16 ... radio stations receive the campaign and 800 women receive radios in campaign areas). Women receiving radios in status quo areas reduce contraception use by 5.2 percentage points. This negative effect is concentrated among those who wanted fewer children, consistent with mass media increasing social pressure to conform to the modal behavior in the media market. In contrast, receiving a radio in campaign areas increases contraception use by 5.8 percentage points. Comparing women in campaign vs noncampaign areas we find contraception use is 5.9 percentage points higher, births 10% lower, misperceptions about contraception lower, and reported welfare 0.27 standard deviations higher in campaign areas."

This book provides a comprehensive yet accessible guide to running randomized impact evaluations of social programs. Drawing on the experience of researchers at the Abdul Latif Jameel Poverty Action Lab, which has run hundreds of such evaluations in dozens of countries throughout the world, it offer ... s practical insights on how to use this powerful technique, especially in resource-poor environments. This step-by-step guide explains why and when randomized evaluations are useful, in what situations they should be used, and how to prioritize different evaluation opportunities. It shows how to design and analyze studies that answer important questions while respecting the constraints of those working on and benefiting from the program being evaluated. The book gives concrete tips on issues such as improving the quality of a study despite tight budget constraints, and demonstrates how the results of randomized impact evaluations can inform policy. With its self-contained modules, this one-of-a-kind guide is easy to navigate. It also includes invaluable references and a checklist of the common pitfalls to avoid. Provides the most up-to-date guide to running randomized evaluations of social programs, especially in developing countries Offers practical tips on how to complete high-quality studies in even the most challenging environments Self-contained modules allow for easy reference and flexible teaching and learning Comprehensive yet nontechnical more
