"The Digital Sin City: An Empirical Study of Craigslist’s Impact on Prostitution Trends" (With Jason Chan and Anindya Ghose) [Submitted to ISR] Abstract - The Internet facilitates information flow between sex workers and buyers, making it easier to set up paid sexual transactions online. Despite the illegality of selling sexual services online, Section 230 of Communications Decency Act shields websites from liability for unlawful postings by third parties. Consequently, the websites like Craigslist have become a haven for prostitution-related ads. With increasing number of prostitution-related sites launched over time, it is imperative to understand the link between these sites and prostitution trends. Specifically, in this paper, we quantify the economic impact of Craigslist’s entry on prostitution incidence, and identify potential pathways in which the website affects the sex industry. Using a national panel data for 1,796 U.S. counties from 1999 to 2008, our results suggest that entry of Craigslist to a county is related to a 17.58 percent increase in prostitution cases. In addition, the analyses reveal that a majority of prostitution on Craigslist are induced by organized vice groups as opposed to voluntary participation by independent providers. Further, we find site entry has a stronger impact in counties with past history of prostitution and produces spillover effects in neighboring locations that are not directly served by Craigslist. Sex workers providing niche sexual services are found to increase with site entry. Finally, we find that the observed increase in prostitution arrests cannot catch up with the growth in prostitution trends brought by Craigslist. Our results contribute broadly to the emerging literature on the societal challenges associated with online intermediaries and Internet penetration, and serve to provide guidelines for policy makers in regulating the sex industry in the Internet era.
