Impact Evaluation Repository ‘What did we miss?’ contest

3ie is holding a contest in conjunction with the launch of the first full update of our Impact Evaluation Repository (IER).

The Impact Evaluation Repository(IER) is the first and only comprehensive repository of development impact evaluations and is designed to be useful for researchers, policy makers, and programme managers. Through a comprehensive search of over 45 databases, search engines, and websites 3ie located all published development impact evaluations through the end of September, 2015. The studies are screened to ensure they meet the IER inclusion criteria before they are added to the Repository.

Through the contest, we challenge IER users to locate impact evaluation studies that should be added to the Repository, but which we have missed.  The studies must meet the following criteria:

  • The study must not already be listed in the Impact Evaluation Repository (IER)
  • The study must use at least one of the methods listed below
    • Randomised Controlled Trial (RCT), Regression Discontinuity Design (RDD)
    • Instrumental Variable (IV) estimation
    • Difference-in-Differences (DD)
    • Other fixed or random effects model with an interaction term between time and intervention for baseline and follow-up observations.
  • The study must have implications for development programming beyond a medical efficacy trial.
  • The study must be of at least one program or intervention taking place in a low- or middle-income country.
  • Studies that measure only natural or market based occurrences, or are conducted in laboratory-controlled settings will be excluded.
  • The study must be published in English on or before September 30, 2015

To enter the study, please submit the study citation and full text (if available) to by 17:00 GMT on 22 August, 2016.

Winners will receive a $10 Amazon Gift Card (up to three gift cards per person) for every submitted study that meets the criteria above. Contest winners will be announced by September 15, 2016.
