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...

The paper is about the economic modelling of aggregate consumption expenditure with particular emphasis on the distribution effects of income. Under certain assumptions on the evolution over time of the population of households ("structural stability") we shall derive a first order approximation...

We study changes of the distribution of income, age, occupation, household size via their marginal and conditional densities. The data consists of cross sectional samples from the population of Brithish households drawn over the years of 1968 - 1995. Estimation is carried out nonparametrically...
