This document compares several methods of computing price and quantity indices, with special reference to the small-change computations used by GEMPACK. It also discusses the problem of 'path-dependence' that might arise when using change equations which have no corresponding levels form. Accompanying worked examples, using Excel and GEMPACK, can be downloaded from item TPMH0049 in the CoPS archive.
