Cost-benefit analyses of book repair

Has anyone out there done a cost-benefit analysis of repairing
general collection [library] materials in-house v. outsourcing same?
I have looked at the University of Pennsylvania/CCAHA report.  I've
also heard that Columbia University did such an analysis in the late
'80s or early '90s, but have not been able to lay hand or eye on a
copy of it. Any information would be greatly  appreciated.
