TY - UNPB AB - It has been shown recently that in many different cultural phenomena theturnover rate on the most popular artefacts in a population exhibit someregularities. A very simple expression for this turnover rate has been proposedby Bentley et al. and its validity in two simple models for copying andinnovation is investigated in this paper. It is found that Bentley's formula isan approximation of the real behaviour of the turnover rate in theWright-Fisher model, while it is not valid in the Moran model.
