For purpose of Ted’s analysis, a tax professor is initially defined as any full-time law professor at a U.S. law school (1) self-identifying with one of the tax categories in the AALS faculty listing, (2) who has posted at least one tax or tax-related article in abstract or full text on SSRN. Paul Caron’s listing of new hires and lateral transfers is also reflected. Further corrections are made as requested. As is true of Paul Caron’s ranking of individual tax professors, downloads of all SSRN postings of any tax professor, so defined, are then tallied. Articles co-authored by members of a single faculty are counted only once towards that faculty’s tally.
