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)

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 by using identical data and statistical methods where possible, as well as sometimes extending or augmenting the data or methods. This study concludes that the quasi-experiments performed by OS each contain important errors, oversights or inconsistencies that most often, but not completely, overturn the results claimed in the original OS article.
