WORKING out of cramped, bare offices in a downtown building here in Washington, President-elect Obamas economic team spent the final weeks of 2008 trying to assess how bad the economy was. It was during those weeks, according to several members of the team, when they first discussed academic research by the economists Carmen M. Reinhart and Kenneth S. Rogoff that would soon become well known.
Ms. Reinhart and Mr. Rogoff were about to publish a book based on earlier academic papers, arguing that financial crises led to slumps that were longer and deeper than other recessions. Almost inevitably, the economists wrote, policy makers battling a crisis made the mistake of thinking that their crisis would not be as bad as previous ones. The wry title of the book is This Time Is Different.
In my interviews with Obama advisers during that time, they emphasized that they knew the history and were determined to avoid repeating it. Yet of course they did repeat it. After successfully preventing another depression, in 2009, they have spent much of the last three years underestimating the economys weakness. That weakness, in turn, has become Mr. Obamas biggest vulnerability, helping cost Democrats control of the House in 2010 and endangering his accomplishments elsewhere.
By any measure, Mr. Obama and his team faced a tremendously difficult task. They inherited the worst economy in 70 years, as well as an opposition party that was dedicated to limiting the administration to one term and that fought attempts at additional action in 2010 and 2011. And the administration can rightly claim to have performed better than many other governments around the world.
But their claim on having done as well as could reasonably have been expected to have avoided major mistakes is hard to accept. They considered the possibility of a long, slow recovery and rejected it.
In the early months of the crisis, Mr. Obama and his aides made clear that they would try to learn from the errors of the Great Depression and do better. They achieved that goal. They also left a whole lot of lessons for the people who will have to battle the next financial crisis.
