Andrew Clark holds a PhD from the London School of Economics. He is currently a CNRS Research Professor at the Paris School of Economics (PSE), and previously held posts at Dartmouth, Essex, CEPREMAP, DELTA, the OECD and the University of Orléans. His work has largely focussed on the interface between psychology, sociology and economics; in particular, using job and life satisfaction scores, and other psychological indices, as proxy measures of utility, and thus to help us to understand the structure of individual preferences and therefore of behaviour. His broad area of study is social interactions and social learning. He has published across a variety of journals in Economics and Psychology, and refereed for 160 different journals.
