Last week, I noted that I have authored an essay for the June 2014 issue of Finance and Development on the subject of "Economics and Morality" (51: 2, pp. 34-38), and I offered some snippets from the article.
There there is also an accompanying six-minute podcast/interview from the IMF where I talk about some of these issues. It's called "How Economics Can Inform Moral Decisions." It's on Soundcloud, and a free registration is required to listen or download.
