Florian Bersier

Florian Bersier is an OII DPhil student. He has interests in online reputation, online trust and - more generally - information economics and behavioural economics.


Florian Bersier is currently reading for a DPhil (read PhD) at the Oxford Internet Institute (OII), University of Oxford, with the generous support of a Scatcherd European scholarship and an Economic and Social Research Council studentship.

Florian's research focuses on the determinants and mechanisms of electronic interactions, that is interactions taking place in the cyberspace. Title of the thesis: "Economic Analysis of Interactions in Cyberspace: From eReputation to eTrust".

To be concise, Florian is especially interested in developing economic models able to explain the formation/dynamics of online reputation and the agents' decision to interact with specific entities on the Web.

Prior to coming to Oxford, Florian was a student at the École Polytechnique, Palaiseau, France. During his graduate studies at Polytechnique, Florian accomplished both a Masters in Quantitative Economics and Finance jointly organized by the Department of Applied Mathematics and the Department of Economics at the École Polytechnique, and the Department of Economics and Finance at HEC-Paris, and a research-oriented Masters in Economic Analysis and Policy housed by the Paris School of Economics and the École Normale Supérieure. He also holds a Bachelor of Science in Economics from the University of Lausanne, Faculty of HEC, Switzerland, a Diploma in Economics from the University of Kent, UK, and is a former Microengineering student at the Swiss Federal Institute of Technology.

Regarding his research experience, Florian has worked as a research assistant at the Paris School of Economics and has been an active member of the research team working both at the London School of Economics (LSE) and at the Centre de Sciences Humaines (CSH), New Delhi, India, on the 2008-2009 Palanpur sixth survey (so-called Palanpur, India's economic 'revolution': A perspective from six decades of economic development in a North Indian village). The research team at LSE was and is still headed by Professor Nicholas Stern and the team at CSH by Dr Himanshu.

Beside his academic life, Florian is an experienced web developer, hacker and an Open Source converted and preacher.

Last but not least, as a member of St Antony's College, Florian feels really concerned by the diverse, complex and significant challenges the world we live in faces and strongly believes that the Internet represents one of the most efficient and relevant tools to use and develop in view of dealing with such challenges.
