We explore enforcement spillovers when sanctions at one entity influence behavior at other entities. Our model illustrates when spillovers arise from a regulatory channel and when they arise from a channel not previously emphasized: product markets. Our model motivates empirically-refutable hypotheses, which we test using data from Clean Water Act manufacturers. We find that penalties create po...

Certificate transparency (CT) is an elegant mechanism designed to detect when a certificate authority (CA) has issued a certificate incorrectly. Many CAs now support CT and it is being actively deployed in browsers. However, a number of privacy-related challenges remain. In this paper we propose practical solutions to two issues. First, we develop a mechanism that enables web browsers to audit ...

If an antitrust authority chooses policies to maximize the number of successfully prosecuted cartels, when do those policies also serve to minimize the number of cartels that form? When the detection and prosecution of cartels is inherently difficult, we find that an antitrust authority’s policies minimize the number of cartels, as is socially desirable. But when the detection and prosecution o...

The link structure of the web is analyzed to measure the authority of pages, which can be taken into account for ranking query results. Due to the enormous dynamics of the web, with millions of pages created, updated, deleted, and linked to every day, timeliness of web pages and links is a crucial factor for their evaluation. Users are interested in important pages (i.e., pages with high author...
