CDD, Accra, Ghana, 20-24 April 2015

In partnership with: CDD-Ghana, African School of Economics, Njala University

Program. This five-day meeting will consist of a combination of design clinics, research presentations, and teach-ins on topics critical for designing impact evaluations and field experiments intended to measure the effects of policies, interventions, and programs. Teach in topics will include randomization, statistical power, and threats to the estimation of treatment effects. Throughout the week participants will work to develop their own research designs together with peers and more senior researchers.


Participants. We invite applications from researchers and organizations in the EGAP network and PIs from the African continent that are in the early stages of their career (PhDs, Post Docs and Assistant Professors) as well as from practitioner groups engaged in research on governance and politics. Participants should have a project in the design stage that will likely be implemented. Applicants should further have a background in economics, political science, sociology or agriculture. Applicants with a basic knowledge of statistics and/or econometrics are preferred. Participation will be limited to twelve researchers.

You can apply by sending a short motivational statement and a CV to Please apply before 27 March 2015.
