Troubling job creation research

Research by financial services firm Northern Trust indicates an additional 86,000 jobs need to be created a month to forestall economic growth.

The research, conducted by Asha Bangalore, assesses the impact of entry of new workers into the economy. Even more troubling, Bangalore's work is built on estimates that the sour economic climate will depress recent trends of how many additional workers are entering workforces.

The measure may be warranted based on historical evidence of growth patterns during recessions, however, it still should be noted that without such an impact and basing projections more on recent trends ,an additional 140,000 jobs would have to be created a month.

U.S. employers created an additional 11,000 jobs in November.
