There’s always something to howl about.

So what if lenders are lousy at judging character? Who can’t identify fat people when they’re sitting on the other side of your desk?

Who says all academics are mindless time-wasters? A pair of brave scholars have demonstrated a correlation between obesity and mortgage defaults. A bad credit report is good evidence of insufficient thrift, but a good credit report is evidence of nothing dispositive. A bulging waistline, on the other hand…

We show that obesity is an economically significant predictor of mortgage delinquencies at the county level. In practice, however, loan contracts do not incorporate easily verifiable health risk factors such as obesity. The discrepancy between theory and practice suggests the existence of substantial cross-subsidization and misallocation of funds in the loan market. The potential for business opportunities and policy implications warrants further investigation of our results with more detailed, albeit costly data.

This is pretty dumb, practically speaking, but it’s nice to see that the idea of pre-existing conditions might have a future, now that it’s been outlawed where it actually makes sense, in the health insurance business.

As an aside, our own Tom Vanderwell makes a cameo appearance in this “study.”
