Informed Trading And Cybersecurity Breaches, Joshua Mitts, Eric L. Talley

Faculty Scholarship

Cybersecurity has become a significant concern in corporate and commercial settings, and for good reason: a threatened or realized cybersecurity breach can materially affect firm value for capital investors. This paper explores whether market arbitrageurs appear systematically to exploit advance knowledge of such vulnerabilities. We make use of a novel data set tracking cybersecurity breach announcements among public companies to study trading patterns in the derivatives market preceding the announcement of a breach. Using a matched sample of unaffected control firms, we find significant trading abnormalities for hacked targets, measured in terms of both open interest and volume. Our results …

Faculty Scholarship

The emergence of Big Data challenges the conventional boundaries between governing, exchange, and security. It ambiguates the lines between commerce and surveillance, between governing and exchanging, between democracy and the police state.

How is it that governmental, commercial and security interests have converged, coincided, …

Rethinking Privacy, William H. Simon

Faculty Scholarship

Without denying the importance of the effort to define and secure privacy values, …

The International Privacy Regime, Tim Wu

Faculty Scholarship

Privacy has joined one of many areas of law understandable only by reference to the results of overlapping and conflicting national agendas. What has emerged as the de facto international regime is complex. Yet based on a few simplifying principles, we can nonetheless do much to understand it and predict its operation.

First, the idea that self-regulation by the internet community will be the driving force in privacy protection must be laid to rest. The experience of the last decade shows that nation-states, powerful nation-states in particular, drive the system of international privacy. The final mix of privacy protection that …
