The influential piracy paper by Professors Oberholzer-Gee and Strumpf, although mainly based on proprietary data, contained an 'important complement' to the main results, consisting of four "quasi-experiments" using publicly available data. This replication examines all of these...

Through a stroke of luck, a referee report in the review process at the JPE has been positively identified as the Oberholzer-Gee/Strumpf (O/S) response to my earlier comment.

Felix Oberholzer-Gee and Koleman Strumpf, in their recent paper on file-sharing, provide numerous additional tests and facts to support their overall conclusion that file-sharing has a benign impact on record sales. In this note I attempt to replicate their additional tests and check their...
