• The Journal of Accounting Research and Wiley decided to retract the above article. I disagree with the decision. I believe that the results of the article are academically sound. I provided the Journal with the code, data, and trained model weights to reproduce the results. For parties with reasonable interest, after necessary review, I am also willing to share the codes and model weights.
