This paper uses data from eleven countries on the search volume of select keywords from before and after the surveillance revelations of June 2013, to analyze whether Google users' search behavior changed as a result. The surveillance revelations are treated as an exogenous shock in information about how closely users' internet searches were being monitored by the US government. Each search term was independently rated for its degree of privacy sensitivity along multiple dimensions. Using panel data, our results suggest that cross-nationally, users were less likely to search using search terms that they believed might get them in trouble with the US government. In the US, this was the main subset of search terms that were affected. However, internationally there was also a drop in traffic for search terms that were rated as personally sensitive. Our results suggest that there is a chilling effect on search behavior from government surveillance on the Internet, and that government surveillance programs may damage the international competitiveness of US-based internet firms.
