I've read most of this book. It does its job as an overview of some of the new ideas for economics, but there's a problem. It's a short book and so each author only gets a few pages, but then a substantial part of many chapters is spent describing what is wrong with mainstream economics - as each chapter is written by a different author this means a lot of repetition. I felt that the space could have been used better saying what was right with their economic ideas.
