I'm delighted to say that Steven Landsburg -- professor of economics at the University of Rochester, Slate's Everyday Economics columnist, and author of the just-released More Sex is Safer Sex: The Unconventional Wisdom of Economics -- will be guest-blogging here this week.

His posts will chiefly focus on More Sex is Safer Sex, a book "dedicated to the proposition that logic and evidence trump common sense." (As you might gather, the more sex item is just one of the essays in the book; he'll be blogging about a good deal more than that.) I've long enjoyed Landsburg's Slate columns, and much look forward to his posts.
