Measuring a Dynamic Price Index Using Consumption Data
提出一种构建动态价格指数的新方法，在标准假设下其稳定性与消费者价格指数相当，但在某些时期两者差异显著。
We propose a new method of constructing a dynamic price index (DPI). Under standard assumptions, our DPI is as stable as the Consumer Price Index (CPI). In certain periods, the DPI differs sharply from the CPI.
