Abstract

Online advertising is increasingly subject to antitrust scrutiny. Despite this scrutiny, in their 2010 article in this Journal, James Ratliff and Daniel Rubinfeld emphasized that there is a lack of empirical analysis on whether the large offline advertising market disciplines the online advertising market. In this comment, we summarize recent empirical work in economics that begins to fill this void by showing an effect of offline market restrictions on online advertising markets.
