A Replication of Four Quasi-Experiments and Three Facts from ‘The Effect of File Sharing on Record Sales: An Empirical Analysis’ (Journal of Political Economy, 2007)
(Published in Replication Study)
Abstract
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 quasi-experiments, first, by narrowly using identical data and statistical methods, as well as in a broader sense by extending or augmenting the data or methods. This study concludes that none of the four quasi-experiments provide evidence in support of OS' hypothesis that file-sharing has not harmed record sales.Note of the Editor: The findings should be viewed as tentative until the paper has completed the review process and been published as an article.
