Mary Spector of Southern Methodist University – Dedman School of Law has written Litigating Consumer Debt Collection: A Study, 31 Banking and Finance Services Policy Report 1 (2012).  Here’s the abstract:

Recent press reports have focused attention on some of the weaknesses in the collection of credit card debt. However, relatively little empirical data exists regarding these deficiencies. The project described in this Article was designed to increase our understanding of how debt buyers and their attorneys conduct litigation to collect consumer debts and the effect of such litigation on consumers and the courts.
