How development economics research is actually done

Belatedly, I found Robert Jensen's guest posts to Steven Levitt's Freakonomics Blog. It's an unusual account of how development economics research is actually done.

Robert Jensen's research is characterized by the testing in developing countries of basic economic theory that is yet to be empirically verified in a convincing fashion. As a result, it contributes both to economics in general and to development economics in particular. He's one of my favorite economists.
