The Nuffield Centre for Experimental Social Sciences of the University of Oxford (CESS) is pleased to announce the Sixth International Meeting on Experimental and Behavioral Social Sciences (IMEBESS) at the Utrecht University, Utrecht, Netherlands, on 2-4 May 2019.

IMEBESS was started as a succession of the International Meeting series on Experimental and Behavioral Economics (IMEBE), and had an inaugural meeting at Nuffield College, University of Oxford in April 2014. Since then the meeting has occurred annually, at the Institute for Advanced Study at Toulouse in 2015, at the Libera Università Internazionale degli Studi Sociali Guido Carli in 2016, at the Universitat de Barcelona in 2017, and at the European University Institute in 2018.

IMEBESS intends to bring together researchers in all areas of the social sciences who are interested in experimental methods. We believe that behavioural economics is increasingly informed by a very diverse range of research traditions. Hence, we are particularly interested in the participation of all social science disciplines with an interest in experimental and behavioural research, including anthropology, economics, political science, psychology, and sociology.

Raymond Duch

Raymond Duch is an Official Fellow at Nuffield College, University of Oxford, and the Director of the Nuffield Centre for Experimental Social Sciences (CESS), which currently has centres in Oxford, Santiago (Chile) and Pune (India).

He is currently the Long Term Visiting Professor at the Institute for Advanced Studies, Toulouse School of Economics, a Director of the European Political Science Association, and Vice-President of the Midwest Political Science Association. He is a member of the UK Cabinet Office Cross-Whitehall Trial Advice Panel to offer Whitehall departments technical support in designing and implementing controlled experiments to assess policy effectiveness.

Professor Duch’s research focuses on responsibility attribution, incorporating elements of theory, experiments and analysis of public opinion. In 2008 he published an award-winning book, The Economic Vote, that demonstrates that citizens hold political parties accountable for economic outcomes. His experiments have identified the information shortcuts that individuals deploy for responsibility attribution. More recently, Professor Duch has conducted experimental research into cheating, exploring its implications for tax compliance, corruption and economic performance. Professor Duch has conducted lab, field and online experiments throughout the world He lectures and also publishes on experimental methods. His research appears in the leading political science and economic journals. He is the founder of Behavioural Analytics that advises public and private clients.

Horne, Washington State University), or how the sharing of compromising information about deviant acts can promote trust and cooperation in extra-legal contexts (with D. Gambetta, EUI Florence).
