Robert "Irrational Exuberance" Shiller, one of the leading scholars of behavioral finance, has a new book out, The New Financial Order: Risk in the 21st Century; the introduction's online. I should really be writing about hidden Markov models rather than reading it, much less blogging about it, so I will only say that I can't decide if Shiller's a genius, or mad, or both, but he must be the first person in history to put forward a Utopia in the grand tradition based on completely new kinds of financial markets.
