Physique statistique de phénomènes collectifs en sciences économiques et sociales

[摘要] This article shows how statistical physics may contribute to the modelling of collective phenomena in economics and social science. The main topic here is the study of the global (aggregate) behavior of a large population, when the agents make choices under social influence. We present several examples, starting from pioneering works in economics and sociology, such as those of T. Schelling whose approach has all the flavour of physicists’ approaches.
