|January 2017||Will Ad Blocking Break the Internet?|
with Joel Waldfogel, Johnny Ryan: w23058
Ad blockers allow Internet users to obtain information without generating ad revenue for site owners; and by 2016 they were used by roughly a quarter of site visitors. Given the ad-supported nature of much of the web, ad blocking poses a threat to site revenue and, if revenue losses undermine investment, a possible threat to consumers' access to appealing content. Using unique, proprietary, and site-specific data on the share of site visitors using ad blockers at a few thousand sites, along with Alexa traffic data, we explore the impact of ad blocker usage on site quality, as inferred from traffic ranks, 2013-2016. We find that each additional percentage point of site visitors using ad blockers raises (worsens) its traffic rank by about 0.6 percent over a 35 month period, with stronger eff...
|October 2009||Music for a Song: An Empirical Look at Uniform Song Pricing and its Alternatives|
with Joel Waldfogel: w15390
Economists have well-developed theories that challenge the wisdom of the common practice of uniform pricing. With digital music as its context, this paper explores the profit and welfare implications of various alternatives, including song-specific pricing, various forms of bundling, two-part tariffs, nonlinear pricing, and third-degree price discrimination. Using survey-based data on nearly 1000 students' valuations of 100 popular songs in early 2008 and early 2009. We find that various alternatives - including simple schemes such as pure bundling and two-part tariffs - can raise both producer and consumer surplus. Revenue could be raised by between a sixth and a third relative to profit-maximizing uniform pricing. While person-specific uniform pricing can raise revenue by over 50 p...
