Renaud Foucart,Senior Lecturer in Economics, Lancaster University Management School, Lancaster University. I am an applied microeconomic theorist. This means I try to understand real world puzzles by modelling strategic interactions. This has led me to work on topics as different as smoking bans, Islamic finance, standards and innovation, environmental agreements, urban planning, the comeback of vinyl, online search aggregators and the impact of auditing courts on the selection of politicians. I hold a PhD from Université libre de Bruxelles. Since then I have worked in Oxford, Berlin, Nottingham and now Lancaster University.

The Department of Justice may be on the verge of seeking a break-up of Google in a bid to make it less dominant.
