Research Resources

Our library of practical resources is available for researchers undertaking randomized evaluations and those teaching the technique to others. The resources presented here are curated by J-PAL in partnership with Innovations for Poverty Action (IPA).

Guide: Writing Randomization Code in Stata

This step-by-step guide uses data and an annotated Stata do-file to illustrate how a simple randomization can be carried out using Stata.

Case Study: Developing a Theory of Change and Logical Framework (Log Frame).

Using the example of a J-PAL evaluation in India, this case study illustrates how to construct a log frame and use one's theory of change to pick appropriate outcomes and indicators for measurement.

PDF: Intro to Evaluations

A Randomized Evaluation is a type of Impact Evaluation that uses random assignment to allocate resources, run programs, or apply policies as part of the study design. This PDF contains all the information in the Introduction to Evaluations web page formatted into a single printable document.

Real-World Challenges to Randomization and Their Solutions

A guide to help researchers and implementing partners develop evaluation designs that fit their program’s context. Using real examples from ongoing and completed randomized evaluations, the document describes multiple research designs that accommodate existing programs, mitigate foreseeable implementation challenges, and demonstrate the flexibility of randomized evaluations across contexts.

Stata 101

The Stata 101 Module is designed for users with little or no knowledge of Stata.
