Charles Kenny is a development economist on leave from the World Bank, a Bloomberg Businessweek contributor, a senior fellow at the Center for Global Development, and the author of "Getting Better: Why Global Development Is Succeeding--And How We Can Improve the World Even More" (don't buy it, but the Amazon page has glowing reviews from, among others, Tyler Cowen, Felix Salmon, and Bill Gates).
Kenny lives in Washington DC but was born in Britain; whether he's a naturalized U.S. citizen or not isn't known.
