From a comment on a previous post:
" I wanted to let you and your readers know they can submit a question for Nancy (on Globalization and Inequality) to answer this week through our new online tool, Ask CGD: http://ask.cgdev.org/. The live answer session will be on Friday March 30, from 11am-12noon EST. We also posted a short clip of Nancy giving an overview of the topic on YouTube:http://tinyurl.com/223msb".
Update: Just noticed that William Easterly worked for a brief period in CGD and there is a lecture by him and discussions about his ideas on aid at CGD:
