Intuitively taking out loans just to go to college because everyone says so isn't a good idea, and a new study by the NBER finds that in fact, students who left for-profit schools during the 2006-2008 timeframe were worse off after attending. A key factor, as the WSJ reports, is that most of these students never earned a degree, they dropped out. Making matters worse, and certainly contributing to the fact that over 40% of student borrowers don't make payments, is the fact that these students borrowed to attend the colleges.

The working paper, published this week by the National Bureau of Economic Research, tracks 1.4 million students who left a for-profit school from 2006 through 2008. Because students at these schools tend to be older than recent high-school graduates, they've spent time in the workforce. The researchers used Education Department and Internal Revenue Service data to track their earnings before and after they left school.
