The Effect of Graduated Response Anti‐Piracy Laws on Music Sales: Evidence from an Event Study in France
研究法国HADOPI分级响应法律对数字音乐销售的影响，发现消费者对法律的认知提升使法国iTunes音乐销售增长22-25%，且高盗版类型增幅更大。
Despite the problem that filesharing poses to the creative industries, there is little research on the effectiveness of governmental anti‐piracy policies. This study analyzes how the HADOPI graduated response law in F rance affected digital music sales. Using a panel of sales data from the four major labels, we applied a difference‐in‐difference approach, comparing sales trends in F rance to a control group of E uropean countries. We find that increased consumer awareness of HADOPI caused French i T unes music sales to increase by 22‐25%. The observed sales increase is larger in high piracy genres than low piracy ones, strengthening the causal interpretation of our results.
