A notion of ''behavioral heterogeneity'' of a finite population of households is modelled. It is shown that the higher the degree of behavioral heterogeneity the less sensitive depends the aggregate consumption expenditure ratio upon prices.As a consequence, behavioral heterogeneity implies a...

The following question is analyzed: under what circumstances can one a stable (i.e., time invariant) functional relationship which links aggregate consumption in period t with aggregate income in period t and another "determinants" of consumtion that refer to periods prior to period t and can be...

Using the Family Expenditure Survey (FES) data for the United Kingdom (UK), the paper specifies and estimates a ’complete’ Hilden- brand Kneip (HK) model of consumption, extending earlier efforts that were ’partial’ in nature. As the estimated parameters in the ’partial’ HK model are...

This paper attempts to provide empirical evidence of the positive definiteness of the mean income effect matrix, a sufficient condition for market demand to satisfy the {\it law of demand} derived by H\"{a}rdle, Hildenbrand and Jerison [HHJ(1991)]. Increasing heterogeneity in spending of...

J.M. Grandmont claims in his paper "Transformations of the Commodity Space, Behavioral Heterogeneity, and the Aggregation Problem" (1992) to model "behavioral heterogeneity". By a specific parametrization he defines a subset of all demand functions and assumes that the distribution of the...
