In recent years a number of empirical studies on household consumer behaviour, based on National Sample Survey (NSS) data, have appeared. In their notable contributions published in this journal Bhatta- charya (1966), Joseph (1966, 1968) have examined the feasibility of adopting the linear expenditure model of Stone (1954, 1964) for India. In the present study the authors consider a system of non-linear Engel curves as an alternative hypothesis of consumer behaviour.
