First, let me say that I greatly enjoyed "The Age of Turbulence." It was better than I had expected, mixing Alan Greenspan's personal story with an interesting finance story. I gave it five stars, and consider it one of the best books I have read in the genre.
Second, let me say that I am an actuary who is keen on books about finance, economics, etc., so I have a high tolerance for dry or technical books. I like regression analysis.
However, I found this book very tough going. The topics seemed to be more of a grab-bag of topics, and it was not clear what the theme or thesis was, though one or two chapters were able to hit a stride and were good. This is in contrast to "Capital in the Twenty-First Century" by Thomas Piketty, which is more methodical, but brings each point clearly before proceeding to the next topic.
The arrangement of the book (original edition, hardcover) worked against the writing. I found myself frequently flipping back and forth, as most, but not all charts were in the back of the book. There are over 300 endnotes for a book of only 300 pages. These should have been triaged, with asides embedded into the text as parenthetical clauses, useless notes removed, and only the rest included as end-notes.
I am no editor, and I am not usually picky. However, the endnote mess (including footnotes to endnotes, endnotes embedded in graphs at the back, etc.) drove me to distraction, turning what could have been a mediocre book into something more irritating.
