This research links and extends studies in the business and economics disciplines on factors that affect author ordering and co-authorship in research papers to the real estate discipline. Author ordering measured by alphabetic ordering is associated with journal quality, the number of authors on a paper, the rank of the authors' institutional affiliations, and the authors' domiciles. Having a European co-author increases the likelihood of alphabetic author ordering. Within the real estate discipline, alphabetic author ordering becomes more common over time. Also, similar to the pattern from other disciplines, the percentage of co-authored real estate papers increases over the 17-year period investigated. Of the nine journals assessed, the three core business oriented academic real estate journals-Real Estate Economics, Journal of Real Estate Finance and Economics, and Journal of Real Estate Research-have the highest percentage of co-authored papers, as would be expected from the top tier of academic journals.
