Why Didn't They See the Crisis Coming?

Paul Krugman answers the question: 'why didn't anyone see the financial crisis coming'?

One answer to these questions is that nobody likes a party pooper. While the housing bubble was still inflating, lenders were making lots of money issuing mortgages to anyone who walked in the door; investment banks were making even more money repackaging those mortgages into shiny new securities; and money managers who booked big paper profits by buying those securities with borrowed funds looked like geniuses, and were paid accordingly. Who wanted to hear from dismal economists warning that the whole thing was, in effect, a giant Ponzi scheme?

There’s also another reason the economic policy establishment failed to see the current crisis coming. The crises of the 1990s and the early years of this decade should have been seen as dire omens, as intimations of still worse troubles to come. But everyone was too busy celebrating our success in getting through those crises to notice.
