KRUGMAN: OK. So on the first half of that question, I only know what Jan tells me.... We're looking for rising unemployment over at least the next few months.... I would have guessed that we probably see unemployment continuing to rise, right up to the end of 2011.... And as for when we return to something that looks like full employment, I think the maximum likelihood estimate is, basically, never.... There's nothing visible on the horizon that will cause that to happen... no policy... aiming at returning to full employment... no technology that will drive a large amount of business investment. Historically, in the aftermath of large financial crises countries recover by having a huge exchange rate depreciation, which then leads to an export boom, but since it's basically the whole advanced world that's caught up in this, and there aren't any other planets to export to, that's not going to happen....
he last time we had a global financial crisis, the recovery to full employment was accomplished by a coordinated, large fiscal expansion, known as World War II.... We ought to be doing everything you can. We ought to be having quantitative easing, we ought to be having another round of stimulus.... You'd have to have... stimulus big enough to bring capacity utilization back up to a high enough level that business investment really starts going again....
