    "abstract": "We propose a generic model for multiple choice situations in the presence of\nherding and compare it with recent empirical results from a Web-based music\nmarket experiment. The model predicts a phase transition between a weak\nimitation phase and a strong imitation, `fashion\u0027 phase, where choices are\ndriven by peer pressure and the ranking of individual preferences is strongly\ndistorted at the aggregate level. The model can be calibrated to reproduce the\nmain experimental results of Salganik et al. (Science, 311, pp. 854-856\n(2006)); we show in particular that the value of the social influence parameter\ncan be estimated from the data. In one of the experimental situation, this\nvalue is found to be close to the critical value of the model.",
