World Bank evaluations

Introducing the Development Impact blog

David McKenzie's picture

Welcome to our new blog about impact evaluation. The number of impact evaluations both within and outside the World Bank have increased dramatically in recent years (see Figure below). The World Bank’s DIME initiative reports the number of active impact evaluations at the World Bank has increased from a couple of dozen in 2004 to over 250 in 2010. As a result, there are more producers and more consumers of impact evaluations than ever before – and more questions about how to conduct evaluations, what we are learning from these evaluations, and what can be done to learn more from them.

This blog has been set up by members of the Development Research Group at the World Bank to provide a forum for discussing these issues.

Our goal is to cover a broad range of issues relating to impact evaluations, including:

  • Summaries, critiques,  and discussions of new research papers
  • Discussions of ongoing and planned evaluations
  • Methodological issues in doing experimental and non-experimental evaluations
  • Stories and puzzles from fieldwork
     

We want this blog to be something that is useful to both producers and consumers of impact evaluations, which can provide an opportunity for serious discussion and sharing of experiences. We hope to have a range of guest bloggers from both inside and outside the World Bank.  We encourage all readers to not only participate in the discussions by commenting on blog posts, but also sending ideas and materials for blogs, as well as for guest blogging.

Please let us know in the comments any ideas you have for pressing issues to discuss, or topics you would like to see covered in future posts.
