A Note on the Stochastic Approach to Index Numbers
应用Clements和Izan的指数随机方法到英国酒精数据，发现估计无偏但渐近标准误低估了真实抽样变异性，因此采用自助法获得替代标准误。
In a recent article, Clements and Izan (1987) used the stochastic approach to index-number theory to estimate the rate of inflation and its standard error. Selvanathan (1988) extended their approach to the prices of groups of goods and to prices within groups. In this note, I apply the within-group results to the U.K. alcohol data. Simulation results show that the estimates are unbiased, but the asymptotic standard errors understate the true sampling variability of the estimates. To overcome this problem, I applied the bootstrap technique to obtain alternate standard errors.(This abstract was borrowed from another version of this item.)
