Vanesa Weyrauch and Gala Diaz Langou have developed a conceptual framework to identify factors that help or hinder impact evaluation and analyze how they influence policy. This approach will enable comparison between cases and regions to draw lessons that are relevant beyond the cases themselves.

This paper provides some of the theoretical background to the 3ie PIM project.
