https://maxkasy.github.io/home/files/papers/correction_adaptiveexperimentspolicy.pdfI have read the correction, but honestly I don't understand anything: othe original paper, the critique, and the correction. I feel really stupid. It would take maybe half year to read and figure out this literature, and I am not able to make such investment.
What is disconcerting however is that this board is so lame. People work on hard problems, they make mistakes, mistakes get fixed, people move on. No reason for hate and anymosity hereon.Mistakes should be detected at the review stage. Econometrica usually has 4 referees. Given that none found the mistake implies that they were not chosen well. It does not reflect well on the editor, who is, im my view, really responsible here. The issue is that Imbens is not technically strong enough and has too much of a bias towards certain literatures that he never should havd been the econometrics editor for econometrica.
Hmmm… but he has a great taste for what’s important, and he can ask any tooled up bros to referee. Referees made the mistake but I don’t know whether they were strong or weak. We just won’t know.
