Cohan has done an extraodinary amount of research, and this enables him to paint a vivid picture of the leading personalities at Lazard as well as to capture the firm's quirky culture. But, with the exception of its blistering account of the current Lazard leader, Wasserstein, the reader doesn't get a good sense of exactly what these investment bankers do during their day jobs. What is the nature of their advice, do they earn their keep, and with the benefit of history do they give the right advice? Other than Wasserstein, whom Cohan criticizes as dead wrong and completely mercenary throughout his career, we don't get a good sense of how these bankers do their work.
Absent that insight, and this may be difficult insight to deliver given the nature of the advice and surrounding circumstances, the book tends to degenerate into gossip. Anyone who has worked in a professional firm can, of course, relate to Lazard's dysfunctional culture and can appreciate the value of rainmaking over hard work. So this is quite interesting and perhaps useful gossip. But the real question presented by Lazard is just what do these bankers do and are they errant fiduciaries who take advantage of their influence over a deal to drive it at all costs so as to ensure ridiculously high fees?
With respect to Wasserstein, Cohan's contempt shines through. He does seem to represent everything that is wrong with Wall Street, though in fairness to him, his IPO of Lazard has worked out far better than I would have thought.
The author seems more favorably disposed to Rohatyn, Ratner, and Meyer, though there is not enough data about the specific deals they worked on to draw a conclusion.
This is an interesting book that is very well written and that gives some real insight into the workings of a famous Wall Street firm. But it ultimately does not grapple with the larger issues presented by the business or offer any suggestions for change.
