Given the pressure from the Department of Justice, Google agreed to ban pharmacies not certified by the National Association of Boards of Pharmacy (NABP) from sponsored search listings. Using comScore click-through data originated from health-related queries, we study how the ban affects consumer search and click behavior in a difference-in-differences framework using the synthetic control method. We find that non-NABP-certified pharmacies receive fewer clicks after the ban and this effect is heterogeneous. In particular, pharmacies not certified by the NABP, but certified by other sources (other-certified websites), experience an increase in organic clicks that partially offsets the loss in paid clicks after the ban. In contrast, pharmacies not certified by any certification agencies experience much lower rates of substitution in organic clicks. These results suggest that the ban has increased the search cost for other-certified websites, but at least some consumers overcome the search cost by switching from sponsored to organic links. The lower substitution for uncertified websites may be explained by the rising consumer concerns about the quality of drugs sold on uncertified websites after the ban.Working Paper Series (National Bureau of Economic Research)no. w20088.Banning Foreign Pharmacies from Sponsored Search Search • Learning • Information and Knowledge • Communication • Belief • UnawarenessjelcGovernment Policy • Regulation • Public HealthjelcEnergy, Environmental, Health, and Safety LawjelcRetail and Wholesale Trade • e-CommercejelcSearch • Learning • Information and Knowledge • Communication • Belief • UnawarenessGovernment Policy • Regulation • Public HealthEnergy, Environmental, Health, and Safety LawRetail and Wholesale Trade • e-CommerceD83jelcI18jelcK32jelcL81jelcChesnes Matthew1366410Dai Weijia (1366411Jin Ginger Zhe1366412National Bureau of Economic Research.MaCbNBERMaCbNBERBOOK9910708149803321Banning Foreign Pharmacies from Sponsored Search3389016UNINA00896nam 2200217 i 450099100438373780753620250915110126.0250609s2008----it a | b 001a0dita d9788860140333Bibl.
