Abstract

Abstract:\nThe paper presents a method for computing the curvature implicit in the use of superlative price\nindices. It extends the quadratic lemma and allows us to compute the elasticity of substitution of the\nunderlying preferences in the direction of the observed price change for the Törnqvist and the\nquadratic mean of order r indices. It derives the expressions for the directional shadow elasticity of\nsubstitution and applies the results to the Norwegian CPI data base.\nKeywords: elasticity of substitution, superlative index, consumer price index (CPI).
