Read more...This post first appeared on April 16, 2007 I always take note when a writer takes a position that is contrary to his usual stance. Tyler Cowen of Marginal Revolution is an intelligent and thoughtful commentator, but hews too closely to free market orthodoxy for my taste. But his review of Maggie Mahar’s Money- Driven […]
Read more...We’ve pointed out from time to time that the financial services industry has lost sight of its role.

Perversely, some businessmen complain bitterly about how […]

The financial market upheaval that started in May is a stark reminder that the conditions that produced the global financial crisis of 2007-08 have not been resolved.

Read more...I must confess that I am only now reading John Brook’s classic Once in Golconda, which is a history of Wall Street from the 1920 to 1938. It’s a heady mix of lush and leisurely narrative with keen attention to financial tradecraft. Of course, any tale that involves market manipulation, no matter how far in […]
Read more...A sudden bout of semi-candor from BP suggests the top brass of the miscreant oil company recognized that it is in such deep doo-doo that the normal corporate PR playbook is no longer operative.
