Define intake and consent process
Far from a simple administrative step, decisions about a study’s intake and consent process are critical for the success of a study. This process can affect statistical power, bias, and the validity of the study through effects on the composition of the consented study sample, the intake/consent...

Power calculations
This section is intended to provide an intuitive discussion of the rationale behind power calculations, as well as practical tips and sample code for conducting power calculations using either built-in commands or simulation. It assumes some knowledge of statistics and hypothesis testing. Readers...
Research resource
Implementation monitoring
Researchers should monitor the implementation of a program to preserve its integrity of the program and collect additional information that can inform the generalizability of the results of the program. There is a variety of methods available to researchers, such as administrative data, site visits...

Resources for conducting remote surveys
As with in-person surveys, remote survey work involves considerations at every stage of the project lifecycle. This page summarizes key points regarding remote surveys and, where applicable, lists J-PAL’s related public resources, in which more detailed guidance can be found. In restricting the...

Introduction to measurement and indicators
The goal of measurement is to get reliable data with which to answer research questions and assess theories of change. Inaccurate measurement can lead to unreliable data, from which it is difficult to draw valid conclusions. This section covers key measurement concepts, means of data collection...
Evaluation
Electronic Food Vouchers and Poverty Reduction in Indonesia
In partnership with the Government of Indonesia, researchers conducted a randomized evaluation to compare the efficacy of vouchers versus in-kind transfers in reducing poverty and improving program delivery. The reform led to an increase in assistance received by eligible households, due to improved targeting. As a result, poverty fell by 20 percent among the poorest households.
Research resource
Pre-analysis plans
A pre-analysis plan (PAP) describes how researchers plan to analyze the data from a randomized evaluation. It is distinct from the concept of pre-registration, which in economics is the act of registering a research project in a registry such as the AEA RCT Registry before the intervention begins...
Research resource
Trial registration
This resource provides guidance for researchers wishing to register their study in a public trial registry. We list common social science registries and registration policies of common funders and economics journals. We additionally describe registration considerations such as the level of detail to...

Ethical conduct of randomized evaluations
This resource is intended as a practical guide for researchers to use when considering the ethics of a given research project. It draws heavily from J-PAL’s own ethics training for research staff and Rachel Glennerster and Shawn Powers’s chapter in the Oxford Handbook of Professional Economic Ethics...

Institutional Review Board (IRB) proposals
Institutional Review Boards (IRBs) review research involving human subjects to ensure that participants are protected from potentially harmful research. This resource provides an overview of the roles of IRBs and ethics guidelines. It also includes practical tips for researchers preparing IRB...

Grant proposals
The first step in embarking on a research project is often writing the grant proposal to fund it. Outside of securing funding for your project, the main purpose of the grant is to lay out your research question and methodology, explain its value to the research and/or policy community, and...

Quick guide to power calculations
This resource is intended for researchers who are designing and assessing the feasibility of a randomized evaluation with an implementing partner. We outline key principles, provide guidance on identifying inputs for calculations, and walk through a process for incorporating power calculations into...
