Economist Robert Brusca thinks he knows:
Right now the job losses in this cycle number 6.9mln, a drop of 5.9% from the peak. It has taken 19 months to get these losses in place. The metrics above suggest that the forecast of how long it will take to get them back should be about 19 months as well (we’ll use 20 months since jobs are still falling). And while that is a long time – nearly two years- it is not so long to restore 6.9mln jobs. If we get them back in 20 months it will take job gains averaging 345,000 per month. Right now that seems like an amazing number. Yet, that is what history says happens. So we’ll see.
