I have just been asked by a propsective MSc student for recommended reading. A more formal page will follow but here is my reply:

Alongside Kahneman’s Thinking Fast and Slow, Thaler and Sunstein’s Nudge, be sure to check out anything by Christopher Hsee, George Loewenstein or Jon Elster.

Also Tyler Cowen at the Marginal Revolution blog is an excellent model of an economist thinking rigorously about everything and so often has good behavioural insights.
