Last week we blogged about the peer-reviewed academic literature studying whether piracy harms sales, showing that articles in peer-reviewed journals overwhelmingly find that piracy causes harm to producers by reducing legal sales and revenues. In today’s blog, we will cover a second important policy question regarding piracy: Does piracy harm consumers?
In contrast to the first question, there is little evidence informing this question within the peer-reviewed literature. The reason it is more difficult to determine the effect of piracy on consumers is because there is a major difference between the short run and long run effects of piracy, and it is more difficult to identify and prove long run effects. In the short run, if we assume that the number and quality of creative works produced is fixed, then piracy benefits consumers in two ways. First, consumers who otherwise would have purchased the product at its normal price can now consume the product for free. Second, consumers who otherwise wouldn’t have purchased the product (because their expected value of the product was less than the price) can now consume products they wouldn’t have otherwise been willing to purchase.
But, although piracy may benefit consumers in the short run, it may harm them in the long run. If piracy reduces revenues to producers, economic theory suggests that producers will choose to supply fewer goods and invest less in quality. Does this effect show up in the data? Do consumers lose as a result of piracy? This is a very difficult question, because piracy appeared as a result of the digitization of media goods, and this digitization also brought with it a number of technologies that reduced the cost of producing, distributing, and promoting media products.
There is an established peer-reviewed literature demonstrating that the overall impact of digitization (which includes both piracy and all of these cost-saving technologies) has been to increase the number and appeal of products being offered (see, for example, Waldfogel 2012 and Waldfogel 2015). But this literature leaves unanswered the question of what piracy’s impact would be if it had not been accompanied by such large cost reductions. Would growth in media be higher if not for the revenue-cannibalizing effects of piracy? And does piracy have a redistribution effect on the supply of content?
We are aware of only two studies in the literature addressing these specific questions: Telang and Waldfogel (2014) and Danaher and Smith (2016). Telang and Waldfogel study Bollywood, the Indian film industry, from 1985-2000. They show that after 1985, VHS piracy coupled with a weak copyright regime led to significant reductions in the revenue that filmmakers could make per movie, even conditional on quality. During this time, Telang and Waldfogel show meaningful reductions in both the quantity of Bollywood films produced and the quality of those films, as measured by IMDB consumer reviews. Similarly, Danaher and Smith (2016) show that the number of Academy Award winning films from countries with high levels of piracy has diminished relative to films from countries where piracy has been less impactful. Thus, while not conclusive, the available empirical evidence seems to suggest that piracy may cause long-term harm to consumers by reducing the supply and quality of new content.
But there is one more important question regarding piracy: what types of firm strategies or government policies are effective in mitigating the negative impact of piracy on revenues? We will tackle that question next in a third and final blog post on this subject.
