The Measurement of Inflation: A Stochastic Approach
用随机方法测量通货膨胀，将每种商品价格变化视为对潜在通胀率的独立观测，通过平均所有价格来估计通胀，并推导标准误差，用澳大利亚数据验证。
The stochastic approach to index number theory views each commodity price change as an independent observation on the underlying rate of inflation so that inflation can be estimated by averaging over all the prices. This article extends the approach by (a) allowing for sustained changes in relative prices, (b) showing the link with Divisia index numbers, and (c) deriving standard errors for the inflation estimates. The results are illustrated with Australian data.
