With the celebrated exception of Nouriel Roubini, an economist from the Stern School of Business of New York University. At just the time Bernanke was testifying about the “contained” real-estate problem, Roubini was publishing a paper arguing that the depressed housing market was nowhere near its bottom, that its contraction would be the worst in many decades, and that its effects would likely hurt every part of the economy. In September 2006, with markets everywhere still on the rise, he told a seminar at the International Monetary Fund’s headquarters that the U.S. consumer was just about to “burn out,” and that this would mean a U.S. recession followed by a global “hard landing.” An economist who delivered a response dismissed this as “forecasting by analogy.” The IMF’s in-house newsletter covered Roubini’s talk as a curiosity, under the headline “Meet Dr. Doom.”

Roubini is thus enjoying his moment as the Man Who Was Right, a position no one occupies forever but which he is entitled to for now. As markets have collapsed, the demand for his views and predictions has soared. He travels constantly, and late this spring I met him in Hong Kong to ask what he was worried about next.

Roubini, who is 50, has a tousled look, from his curly black hair to his rumpled clothing. The initial impression he gave was of total physical exhaustion. When he spoke, at mid-afternoon in Hong Kong, he would scrunch his eyes closed tight, as if forcing himself awake, and shove his suit jacket sleeves and shirt sleeves high up from his wrists to his forearms in the same effort.

You often see this paralyzing fatigue in people who’ve recently made the flight to Asia. What was unusual in Roubini’s case is that even with eyes closed he kept emitting high-speed and complex answers, which proved on transcription to consist of well-formed sentences and logical sequences. They were delivered in an accent that is what you might imagine from someone who spent his first 20-plus years in Turkey, Iran, Israel, and Italy before going to the United States as a graduate student at Harvard. In a few cases, I later realized, the polish of his responses was because he was reciting passages from papers he had written, as if from an invisible teleprompter. But mostly he seemed to be drawing on data points and implications that were so much on his mind they could be processed and expressed even when the rest of him was spent.

The conversation was surprising in three ways: for the relatively high grades Roubini gave Treasury Secretary Timothy Geithner, generally the least-praised member of the Obama economic team; for the overall support (with one significant exception) he expressed for the administration’s response to the economic crisis; and for his willingness to look far enough beyond today’s disaster to speculate about the problems a recovery might bring. He was also full of advice about China’s reaction to the world financial crisis, including the suggestion that its options are narrower than its leaders may grasp.
