Don Boudreaux at Cafe Hayek had a very useful post a couple days ago. It was a letter he sent to The Washington Post regarding a recent article. The article itself is interesting and useful. If you want to help your students understand exports and be able to counter various myths about exports, it's just the thing.
But as Boudreaux points out, it has a misconception - a myth if you will - of its own and he is as eloquent as ever in explaining it. And in the process reminded me of the dual nature of Gross Domestic Product. I look forward to your comments.
