Abstract

This country-level impact study for Ethiopia combines ex-post and ex-ante estimation of research gains from improved sorghum varieties developed by the National Breeding Program of Ethiopia in collaboration with partners from international research institutions and universities. The methodological framework for the study is the standard economic surplus concept embedded in the DREAM model within a multiple domestic market configuration, price spill-overs, and separate impact parameters (adoption path and yield differentials) for each improved sorghum variety under consideration. Several model scenarios are developed and applied to test the robustness of impact parameters and portray components of ICRISAT’s development approach in the socioeconomic domain. One group of scenarios refers to ICRISAT’s traditional breeding and crop management activities. The other group captures elements of ICRISAT IMOD strategy (Inclusive Market Oriented Development) by defining various markets and trading frameworks.
