People on twitter might be joking, but in all seriousness, we would see a bigger boost in spending and hence economic growth if the earthquake had done more damage.
As one of the comments at the link puts it, "Japan's economy should be skyrocketing, then."
Why stop there? Get some flash "Economic Recovery" mobs ready to go smash some windows.
You know who benefits from this? The hometowns of whoever the NBA Championship, World Series and the Superbowl. Riots in the streets, turning cars over and burning couches.
This is the sort of economic recovery Detroit, Michigan revels in.
Kinda Related: You know who can use a good earthquake riht about now? Illinois.
Illinois lost more jobs during the month of July than any other state in the nation, according to the most recent Bureau of Labor Statistics report. After losing 7,200 jobs in June, Illinois lost an additional 24,900 non-farm payroll jobs in July. The report also said Illinois’s unemployment rate climbed to 9.5 percent. This marks the third consecutive month of increases in the unemployment rate.
Update: Allahpundit at Hot Air has some doubts if it's really Krugman or some parody.
Is it real or just a goof? Kevin Williamson isn’t sure and neither am I, but given that this is the same guy who fantasized recently about the Keynesian awesomeness of an alien invasion, it’s at least a toss-up. All day long I’ve felt relieved that the quake caused only very minor damage, but now suddenly I’m bummed that the Brooklyn Bridge didn’t fall into the river. Maybe we can get DHS or the NYPD to blow it up? That’s a few thousand jobs right there.
Here's the deal. As with the space aliens comment, Krugman has said some stupid things in the past. The line between what's parody and what he really has said tends to get blurry.
Update II: It's fake but accurate:
[H]ere’s the man himself weighing in. It wasn’t his Google+ page. Duly noted, and I apologize for the error. But I hope he addresses the argument in the fake tweet on his blog. If World War II ended the Great Depression, why is it outrageous to think a Keynesian might see an economic boon to a natural calamity?
What a bummer.
