2013 Training Course - Impact Evaluation and Analysis of Development Interventions

Event Date: 
13 May, 2013 - 18 May, 2013 
International Food Policy Research Institute (IFPRI), Dakar, Senegal 



Over the course of the past ten years, the number of impact evaluations related to development interventions has increased substantially. In fact, under the leadership of leading academic institutions in the US and Europe, empirical studies based on robust comparisons of treatment and control groups have received considerable financial support from the donor community and led to dozens of publications in leading academic journals in the areas of agriculture, education and health..

At the heart of this movement has been a widely-shared idea that impact evaluations can contribute to development effectiveness by helping to determine “what works and what does not”, and that this research can be used to influence policy. Yet, despite an estimated 250 on-going or completed impact evaluation studies in Africa conducted by NGOs, the World Bank and universities, only a handful of these involve researchers from African universities. Why?  And how can this be changed?

This course intends to provide African-based researchers with knowledge of the latest developments regarding both technical and topical aspects of impact evaluation. The course is also meant to help build a high-level network of local impact evaluation practitioners and partners of within the region.

course information

The course will be organized into two* one-week courses in Dakar, Senegal. Each course will be further divided into three two-day modules focused on a particular strand of literature that is of current relevance for impact evaluations in the region, and taught by a leading academic in the field. Sector-specific topics include agriculture, education, finance, health, infrastructure and safety nets. In each module, the training will cover theoretical and empirical areas in that literature, apply that learning by replicating a real-life impact evaluation, and a discussion of a participant’s research and how these techniques could be applied.

*A follow up course will be offered in Fall 2013.  We ask that you attend both the Spring and Fall courses.

The Spring course will be organized as follows:

Session 1: May 13, 2013 (2 hours)
Instructor: Tanguy Bernard (IFPRI)
Topic: Introduction of the AGRODEP Impact Evaluation Network (AIEN)
  • Fifteen years of impact evaluations in Africa: themes, teams and geography
  • Impact Evaluations and the conduct of research in African research centers
  • Objectives of the AIEN
  • The tools of the AIEN
  • A network of high-level Africa-based researchers involved in the design and conduct of impact evaluations
  • A network of world-class professionals involved in Impact Evaluations, supporting AIEN with training and mentoring
  • A set of ad-hoc tools to support proposal designs, data analysis, and paper writing
  • Looking forward: 2013 and 2014 plans for the AIEN.
Session 2: May 13-14, 2013 
Instructor: Jenny Aker (Tufts University) 
Topic: The design, relevance and implementation of Randomized Control Trials, with a particular focus on power calculations in RCT contexts
  • Overview of Impact Evaluation --What is it?  How can it be used? What are the different methodologies? (RCT, RDD, DD, PSM, IV) (This will be an interactive session)
  • The Econometric Framework for Impact Evaluation: Different Treatment Effects (ATT, ITT, LATE). This includes a practical case study from Niger, and mentions ITT and LATE, which Ruth will cover later
  • Randomization: What is it?  What are the different approaches?  How can it be used? 
  • Case study on using RCTs in their work
  • What's power got to do with it?  Estimating sample size in RCTs and other evaluations
Session 3: May 15-16, 2013
Instructor: Alan de Brauw (IFPRI)
Topic: Recent developments in the impact evaluation of Safety Net programs, with a particular focus on applying regression discontinuity designs to such issues.
  • Social Protection Programs: The goal is to set up the idea of social protection, with a broad overview of programs and more specific details on CCT programs.  I'll talk specifically about what we know about what works and then what is happening in Africa in CCT programs or other social protection (pension in South Africa).
  • Targeting in Social Protection: How do we get benefits to those who need them, and how does that affect methods to evaluate social protection programs?  How to target programs well (do we know)?
  • Regression Discontinuity Design- From targeting, what it measures (LATE), why it is akin to a localized experiment, and examples of how regression discontinuity has been used to evaluate CCTs?
  • Example based on the CCT evaluation of Comunidades Solidarias Rurales in El Salvador
Session 4: May 17-18, 2013
Instructor: Ruth Vargas Hill (IFPRI)  
Topic: Recent developments in the study of weather insurance, with a particular focus on dealing with partial compliance in impact evaluation designs.
  • Managing threats to analysis (2 hours)
  • Attrition: attrition and differential attrition
  • Spillovers
  • Partial Compliance: Estimating Intention to Treat, Local Average Treatment Effects
  • Partial Compliance: Encouragement design
  • Examples from randomized control trials in index insurance (1 hour)
  • Case-study exercise 1 (1.5 hours)
  • Increasing power through repeated measures (45 minutes)
  • Examples from randomized control trials in agricultural markets  (45 minutes)
  • Case-study exercise 2 (1.5 hours)

Participants of the training will be given access to a dedicated space within AGRODEP website, with access to relevant material (papers, datasets, problem sets, blogs, conference announcements and others), as well as a discussion forum for group members to share experiences and information and to receive feedback on on-going work. Further training sessions and group meetings shall also be available for the upcoming years.
