唱片市场的层次结构
Hierarchical structure in phonographic market
摘要：
我发现了一个拓扑安排的资产交易在一个唱片市场相关联的一个有意义的经济分类。我继续使用最小生成树和资产之间的相关性寿命，但现在不在股票市场。这是第一次尝试使用这些方法对唱片市场，我们有艺术家，而不是股票。一个艺术家的价值是由唱片销量决定的。该图是从计算世界上最受欢迎的30位艺术家之间的相关系数矩阵开始，通过考虑每周唱片销售对数的差异的同步时间演变来获得的。这种方法提供了唱片市场的层次结构和信息，音乐流派是有意义的，根据客户。
英文摘要：
I find a topological arrangement of assets traded in a phonographic market which has associated a meaningful economic taxonomy. I continue using the Minimal Spanning Tree and the Life-time Of Correlations between assets, but now outside the stock markets. This is the first attempt to use these methods on phonographic market where we have artists instead of stocks. The value of an artist is defined by record sales. The graph is obtained starting from the matrix of correlations coefficient computed between the world's most popular 30 artists by considering the synchronous time evolution of the difference of the logarithm of weekly record sales. This method provides the hierarchical structure of phonographic market and information on which music genre is meaningful according to customers.
