<p>Interestingly, the authors of the revealed preferences working paper </p>
<p>are now preparing their work for peer-reviewed journal publication (as I learned from an email from one of the co-authors). I think it will be interesting to see how their claims will be edited and refined in response to referee comments, and what the scholarly response to the hoped-for published paper will be. I think their methodology is a valuable addition to the discussion of how to rank colleges, but I have confirmed through email with that co-author that the authors certainly don't claim that the rankings they found in one dataset are written in stone for all time. Maybe student preferences are changing, and almost for sure the data set they had was not exactly representative of all students who aspire to enroll at the most-preferred colleges, but their oversampling of one group of students had a plausible practical reason, and produced a preliminary report that has generated a lot of interest debate about methodology.</p>
