Associate Professor of Economics at the OII, University of Oxford
Welcome and Biography
Hello, and a humble welcome to my homepage. I am
an academic economist working on industrial economics, with a specialism in the economics of competition in technology and digital markets;
the Director of Graduate Studies at the OII, with overall responsibility for taught and research postgraduate study across four degrees within the department;
I work on projects to apply tools from economics to help understand how online markets and markets for technology goods work, when such markets are most likely to fail, and what policymakers can do to fix them. I am particularly interested in the role of online platforms, online advertising, consumer search, and online media. Much of my work is motivated by ongoing policy or regulatory challenges, and I also work with government, policy making bodies, and regulators to implement insights from my work and from economics more generally in policy.
High-level examples of the kinds of topics that I have covered in my research include
competition in data-rich markets;
the effects of intermediary bias on competition and its implications for consumers;
bundling in technology markets;
price comparison websites and market structure /competition;
the truthfulness of online advertising;
bidding strategies in online auctions.
Most of my research falls within the domain of applied economic theory, especially industrial organisation, information economics, competition (antitrust) policy, and other applications of game theory.
I teach a one-term course in Internet Economics that serves the dual role of introducing social science graduate students to economics as well as covering some of the more important substantive topics in the economics of technology. The course has a conscious slant towards policy analysis and policy-relevant issues. Current topics covered include reputation, information and price discrimination, network effects and switching costs, platform markets, consumer search, competition policy, intellectual property, and data and privacy. Students also get a grounding in micro theory and game theory.
