The latest Wall Street Journal Econoblog features Alex Tabarrok and Bryan Kaplan from Geroge Mason University's Economics Department. They apply economic reasoning to the decision of presidents to go to war, hidden fees in car rentals, and a novel idea for deciding whether to fire CEOs. Good stuff.
For those who aren't familiar with these two, the run a couple of excellent blogs: Alex is at Marginal Revolution and Bryan's at Econlog. Both are part of my daily reading list (and my blogroll).
