本文使用详细而全面的扫描仪数据来衡量美国预装软件的恒定质量价格变化。由于冬季假期的销售量会大幅增加，因此考虑到季节性变化是很重要的。使用一种新的方法来构建一个季节性调整的生活成本价格指数，明确占消费者的异质性，我发现，从1997年到2003年，恒定质量的软件价格下降了平均15.9%的年增长率。相比之下，美国劳工统计局（Bureau of Labor Statistics）报告称，预装软件的平均年价格下降幅度仅为7.7%。
This paper measures constant-quality price change for prepackaged software in the US using detailed and comprehensive scanner data. Because there is a large sales surge over the winter-holiday, it is important to account for seasonal variation. Using a novel approach to constructing a seasonally-adjusted cost-of-living price index that explicitly accounts for consumer heterogeneity, I find that from 1997 to 2003 constant-quality software prices declined at an average 15.9% at an annual rate. As a point of comparison, the Bureau of Labor Statistics reports average annual price declines of only 7.7% for prepackaged software.
