Hm, I think the blog should have at least mentioned this book too:

Thaler and Sunstein are both pretty popular and well regarded professors/authors. If one is looking for insights into behavioral economics, I also recommend Nobel Laureate Daniel Kahneman's Thinking Fast and Slow, as he is basically the father of the field.
