A byproduct of the COVID-19 pandemic and of social distancing is a sharp increase in online activity. This magnifies existing digital privacy challenges and introduces new ones. There is a lot that we don't yet understand, but some that we do. A short interview that I gave on the issue is available here. It is based on my paper Digital Privacy with Andrea Galeotti and Ruslan Momot.

Thank you to Luohan Academy for covering our work in their Frontiers magazine. While it is correct that we recommend enforcement against online adversaries, our policy recommendations also include regulation of digital businesses, in particular, holding businesses liable for damage to users and a minimal level of data protection requirement. Scroll down for a video of a short talk in which I cover our main results and policy recommendations.

My co-author, Ruslan Momot, is on the US market in Operations Management. In a new paper, Ruslan and I, together with Andrea Galeotti, develop a framework to study Digital Privacy. We find that—contrary to public opinion—advertisement-driven companies do not invariably retain more of their users’ data than do transaction-driven companies, and that measuring the direct damage inflicted by malicious parties on users significantly underestimates the welfare loss and the loss of consumer surplus due to adversarial activity.

In a new paper, joint with Dominique Lauga and Elie Ofek, we study a model of Ratings, Reviews, and the Marketing of New Products. We show that whether consumers share just ratings or full reviews online has implications to the firm's pricing and advertising efforts, and affects profits and welfare.

In a recent paper, joint with Andrea Galeotti, we develop a model of The Market for Online Influence and study the growing practice of Influencer Marketing.  The paper was covered by Changing Business Magazine and by the London Business School Review. Here's a trailer:
