Fun fact: overriding regulatory data with #alternativedata is also what Dennis, Gerardi & Schenone do to support the EFA-best-paper-award-winning claim that #airlinepaper’s results aren't robust to reasonable alternative empirical choices. (The difference to Rock & Rubinfeld is that they don’t call it “reformat” when they come up with #alternativedata. They call it “alternative mapping”, among other things.)
