Humans and financial markets

Well this is exciting: the proof copy of the new book by my brilliant former classmate Andrew Lo (now director of the MIT Laboratory for Financial Engineering) has arrived. It’s Adaptive Markets: Financial Evolution at the Speed of Thought. Paging through, & from conversation with him, the book is a synthesis of modern financial economics and psychology/evolutionary biology, with some AI and neuroscience in the mix. It aims to get away from the stale ‘the efficient markets hypothesis is right/wrong’ dichotomy and looks instead at the interaction between rational calculation and what we know of the structure and non-rational habits of human decision making.

The book starts with a historical perspective; it ends with the financial crisis and recent developments, and discusses what regulatory framework is appropriate. A proposal that seems utterly sensible is to establish a financial market analogue to the National Transportation Safety Board, a standing expert (sorry!) body that investigates transport accidents to determine causes and recommend regulatory adjustments if necessary.

I can’t wait to read it. The book is equation-free and I know from graduate school experience that its author (also co-author of the classic A Non-Random Walk DOwn Wall Street) is so clever he can explain really difficult things ultra-clearly. Looks like one for all interested in financial markets. It will be out in April so I’ll review it properly closer to the date.)
