General Classes of GEKS‐Type Price Indices With Application to Scanner Data
提出了三类广义的GEKS型价格指数，其特例包括常见的GEKS、CCDI和GEKS-W公式，并通过公理化分析推荐了基于Lloyd-Moulton指数的一类，其特例为近期发表的GEKS-L和GEKS-GL指数。
This article addresses the problem of selecting a price index dedicated to scanner data, with attention directed toward multilateral GEKS‐type indices. The article proposes three general classes of GEKS‐type indices, the special cases of which are reduced to the well‐known GEKS, CCDI, or GEKS‐W formulas. The main purpose of the article is to analyze the axiomatic properties of the proposed index classes. The practical conclusion of the analysis seems to be the recommendation of a general class of GEKS‐type indices, which is based on the Lloyd‐Moulton index and of which the recently published GEKS‐L and GEKS‐GL indices are special cases.
