An Experimental Evaluation of Regret-Based Econometrics
Using data obtained in a controlled ad-auction experiment that we ran, we evaluate the regret-based approach to econometrics that was recently suggested by Nekipelov, Syrgkanis, and Tardos (EC 2015). We found that despite the weak regret-based assumptions, the results were (at least) as accurate as those obtained using classical equilibrium-based assumptions. En route we studied to what extent did humans actually minimize regret in our ad-auction, and found a significant difference between the "high...

The “Internet of Things,” in which everyday objects possess network connectivity that allows them to send and receive data, is poised to radically transform the way we live and work. As part of their collaborative series on engineering and entrepreneurship, the Harvard John A. Paulson School of Engineering and Applied Sciences and the Harvard Business School will host a symposium on the Internet of Things, exploring the thrilling opportunities it provides for technological innovation and social...

Title: Political Turbulence: How Social Media Shape Collective Action
Abstract: How does the changing use of social media affect politics? In a recent book - Political Turbulence, Princeton University Press, 2016 - Helen Margetts and colleagues Peter John, Scott Hale and Taha Yasseri show how social media are now inextricably intertwined with the political behaviour of ordinary citizens, and exert an unruly influence on the political world. As people go about their daily lives, they are invited to...
We initiate a formal research of the privacy-efficiency tradeoff of secure database systems. Such systems, such as CryptDB and Cipher-base, try to mitigate the high costs of full-fledged cryptographic solutions by relaxing the security guarantees they provide. We provide abstract models that capture the basic properties of these systems and identify their fundamental leakage channels. These models allow performing a generic and implementation...
Title: "The Internet Identity Mess and Opportunities for Improvement"
Abstract: Well into the mainstream Internet's third decade, news about large scale theft of private personal data, including authentication information such as passwords, still comes out with alarming frequency. Meanwhile, even when it isn't stolen, this information is generally perceived to be misused and monetized in ways that disadvantage and disempower the average person. Frustratingly, academicians have known since the...

Title: Descending Price Coordinates Approx
Abstract:
When exploring acquisition targets, firms typically begin with the possibilities offering greatest option value and work their way down, as prescribed by optimal search theory. Yet the market designs economists have often prescribed, involving simultaneous or ascending prices, stymie this process. As a result they may be arbitrarily inefficient when one accounts for the costs bidders must invest to...
