Stiglitz knows all

Joe Stiglitz tells us that
... there have been more than one hundred financial crises worldwide in the last 30 years or so. Here in the United States alone, we have had the S&L crisis in 1989, the dot-com/WorldCom/Enron problems of the early years of this decade, and now the subprime-morphing-into-the-beyond-subprime collapse. In addition to these national problems, there were regional troubles--real-estate crises fed by excessive lending in Texas and the Southwest in the mid-'80s, and in California and New England in the early '90s. In each of these instances, financial markets failed to do what they were supposed to do in allocating capital and managing risk.
But as Arnold Kling points out
Stiglitz always writes as the omniscient observer. He knows exactly what should have been done to prevent or solve each of the 100 financial crises that he cites.

This omniscient-observer vantage point has its limits. It does not convey the uncertainty and trade-offs that policymakers face in real time. For example, as the housing bubble was inflating, there were not many Congressional voices raised against lending to first-time homebuyers.
Knowing all ex post is easy. Knowing it ex ante is a lot harder.

The remarks of Kling that you post are outright false. Kling's simply lying.

Stiglitz does not say that "He knows exactly what should have been done to prevent or solve each of the 100 financial crises that he cites"

Stiglitz merely points out that unregulated financial markets are prone to speculative bubbles and the accompanying busts. That such a mild column of common sense enrages Kling says a lot about Kling...
