The fifth International Initiative for Impact Evaluation (3ie) and IFPRI Impact Evaluation Seminar will be webcast live on December 13 at 12:30 EST. Andrew Zeitlin of the Georgetown Public Policy Institute will speak about lessons learned from a study of fertilizer use among cocoa farmers in Ghana.

Zeitlin will discuss results from the paper Understanding Heterogeneity: Risk and Learning in the Adoption of Agricultural Technologies. This paper investigates the relationship between farmers’ experience with a new technology and their decision to continue or discontinue its use.

The International Initiative for Impact Evaluation (3ie) and IFPRI Seminar Series highlights the latest impact evaluation research and facilitates discussion of how to bring improvements and innovation to the field of impact evaluation. The 3ie-IFPRI Seminar Series presents speakers and discussants whose work features innovative methodologies and addresses crucial evaluation questions. The series began in May 2012 and will continue into 2013.
