Overview

My research interests lie at the overlap of information technology, society, and economics. They include, primarily, the economics and behavioral economics of privacy and information security, and privacy in online social networks. I am maintaining a page with resources on the economics of privacy. I am interested in the economic impact of privacy protection and privacy intrusions, the relations between privacy and economic rationality, and the dichotomy between expressed privacy attitudes and actual revealed behavior.

My previous research interests included the many ways the interaction and interconnection of human and artificial agents affect highly networked information economies, producing an hybrid form of capital that I call intelligent capital. They also included voter-verifiable electronic schemes for receipt-free, universally verifiable elections with write-in ballots.

A list by publication type is included in my CV.
