Show Summary Details


This is the last of five chapters about the cost of living problem and price indices, a typical area for what is understood as choice theory. Together with the previous two chapters, it discusses theoretical matters arising from the finding of S. S. Byushgens (1925) that Irving Fisher's ‘Ideal Index’ is exact if demand is governed by a homogeneous quadratic utility. Specifically, it addresses the A. Wald's ‘New Formula’. The four sections of the chapter are: linear expansions; revealed purchasing power; yhe critical points; and marginal price indices and limits.
