A Demographic Analogy for Shareowner Accounts
本文用人口学类比方法分析一家大公司的股东账户数据，发现账户关闭率随时间异常稳定、开户后很快关闭的比例极高，这些特征在以往关注市场或投资者的研究中未被注意到。
Abstract A demographic analogy suggests categories for statistical analysis of the shareowner accounts of a large corporation, using data from routine record-keeping systems. The study reveals unexpected stability of account closing rates over time, extremely high proportions of accounts closing soon after opening, and other features unnoticed in previous studies of stock ownership, most of which have focused on the market or the investor.
