Hedonic Price Indexes for Spreadsheets and an Empirical Test for Network Externalities
估计了计算机电子表格程序的特征价格方程，并实证检验该行业是否存在网络外部性。研究发现消费者愿意为兼容Lotus平台、链接外部数据库及提供局域网外部性的电子表格支付显著溢价。1986至1991年间，质量调整后的电子表格实际价格每年下降约15%。
In this article, I first estimate hedonic price equations for computer spreadsheet programs, and then use the analysis to empirically test whether network externalities exist in this industry. The study shows that consumers are willing to pay a significant premium for spreadsheets that are compatible with the Lotus platform and for spreadsheets that offer links to external databases, and a similar premium for spreadsheets that offer local area network externalities. Finally, the quality-adjusted (real) price of computer spreadsheets declined by approximately 15% per year from 1986 to 1991.
