"Twenty-five years ago, when most economists were extolling the virtues of financial deregulation and innovation, a maverick named Hyman P. Minsky maintained a more negative view of Wall Street; in fact, he noted that bankers, traders, and other financiers periodically played the role of arsonists, setting the entire economy ablaze. Wall Street encouraged businesses and individuals to take on too much risk, he believed, generating ruinous boom-and-bust cycles. The only way to break this pattern was for the government to step in and regulate the moneymen. Many of Minsky’s colleagues regarded his “financial-instability hypothesis,” which he first developed in the nineteen-sixties, as radical, if not crackpot. Today, with the subprime crisis seemingly on the verge of metamorphosing into a recession, references to it have become commonplace on financial Web sites and in the reports of Wall Street analysts. Minsky’s hypothesis is well worth revisiting. In trying to revive the economy, President Bush and the House have already agreed on the outlines of a “stimulus package,” but the first stage in curing any malady is making a correct diagnosis."
