Richard Buckingham, Diane D’Angelo & Susan Vaughn (all of Suffolk) have posted Law School Rankings, Faculty Scholarship, and Associate Deans for Faculty Research on SSRN.  Here is the abstract:

The authors contend that a boom in law school rankings has encouraged many U.S. law schools to take new measures to encourage and publicize faculty scholarship. The establishment of associate deans for faculty research is one such measure. The authors conducted a study to determine the number of law schools that have these dean-level positions. They argue that many law schools have established these positions as part of their efforts to improve their standing in the increasingly important rankings.

The authors begin with a historical overview of the original law school model and discuss how that model evolved over time. They focus on how those changes led to a competitive law school market that helped lay the groundwork for U.S. News & World Report and other law school rankings. They then explore numerous alternative ranking methodologies and conclude with a study of ABA-accredited law schools that have appointed associate deans for faculty research.
