The Baseline Scenario is a blog about "what happened to the global economy and what we can do about it." It’s run by Simon Johnson, a former chief economist of the International Monetary Fund and a professor at the MIT, Peter Boone, an Associate at the Centre for Economic Performance, and James Kwak, a former McKinsey consultant. They make Roubini seem chipper:
The most likely outcome is not a V-shaped recovery (which is the current official consensus) or a U-shaped recovery (which is closer to the private sector consensus), but rather an L, in which there is a steep fall and then a struggle to recover. A “lost decade” for the world economy is quite possible. There will be some episodes of incipient recovery, as there were in Japan during the 1990s, but this will prove very hard to sustain.
