Applied Economics, 2011, 43, 4699–4705 Factors determining UK album success Caroline Elliott* and Rob Simmons Department of Economics, Lancaster University Management School, Lancaster University, Lancaster LA1 4YX, UK This article uses a recently compiled dataset on the UK album sales to determine which factors contribute to best-selling album sales success. We control for factors including length of time since release, nationality of artist, artist type and album type, testing the increasing returns to information hypothesis. Information on general public online review scores for the albums in the dataset allows for a strong test of the accuracy of online reviews in predicting music sales, as online reviews are a relatively recent phenomenon, while the release of many of the albums predates the widespread use of Internet. I.
