| Abstract: | 
This study examines the impact of peer-to-peer (P2P) file-sharing on the 
Australian theatrical film industry. Using a large data set of torrent 
downloads observed on three popular P2P networks, we find evidence of a sales 
displacement effect on box office revenues. However, although statistically 
significant, the economic significance of this displacement appears relatively 
small. To establish causality, we make use of two precedent-setting Australian 
Federal Court case rulings, as well as observed levels of contemporaneous 
downloading in geographically separated markets within Australia. We observe 
that the release gap between the US and Australian markets is a key 
contributor to piracy early in a film's theatrical life; this finding provides 
a partial explanation for the industry's move toward coordinated worldwide 
rele ases. |
