Richard Thaler, one of the big names in the field of behavioural economics, has a book out called Nudge which looks quite interesting. He also has a blog on the go which you can find here.
And he's giving a lunchtime talk at the RSA later this month. This is actually on the same day as the session on Tomorrow's Investor that I mentioned t'other day, that one is an evening session though. I'm going to try to get to both.
