Demand distribution dynamics in creative industries: The market for books in Italy

摘要

We studied the distribution dynamics of the demand for books in Italy. We found that for each of the three broad sub-markets into which the book publishing industry can be classified - Italian novels, foreign novels and non-fiction - sales over a three-year sample can be adequately fitted by a power law distribution. Our results can be plausibly interpreted in terms of a model of interactions among buyers exchanging information on the books they buy.
