Am I Just a Permabear?

In the comments of this post, Gene Callahan doesn’t shirk his duty of constantly assuming I started reading financial economics last Tuesday: But Bob, weren’t you predicting market disaster when the Dow was at 6000? (I was buying at that point, fwiw.) Weren’t you predicting it through the whole rise of the last seven years? […]

3 Stock Market Tips From an Economist

My latest at FEE. (They picked the title mostly for irony, I think.) You guys think you’ve placed me in a neat little anti-EMH box, don’t you?

I ran a statistical analysis on the National League all the way back to 1876. Do you know that in every single season, when […]

More EMH Silliness

I love this stuff. Scott Sumner scoffs at those thinking Robert Shiller contributed anything useful by warning of a stock bubble in 1996 or a real estate bubble in 2003. He quotes from Fama, who at first seems to blow Shiller up with some numbers. But I’m pretty sure I show that Fama’s arguments make […]
