The Growth of Network Computing: Quality‐Adjusted Price Changes for Network Servers
研究网络服务器质量调整价格的变化，发现偏好特征价格指数比标准匹配模型指数下降更快，主要原因是标准模型因淘汰过时型号而产生选择偏差。
This article investigates the evolution of quality-adjusted prices for servers motivated by two facts. First, the recent productivity acceleration in the US is closely linked to the spread of IT of which networked computing is a large component. Second, the growth of network computing itself has been fostered by the rapid growth in the quality and quantity of server hardware and software. The preferred hedonic price index fell much more rapidly than the standard 'matched model' price index, mainly due to the selection bias in the standard model arising from the exit of obsolete models, which would have had the fastest price falls.
