Abstract: This paper examines household consumption patterns in Pakistan by estimating three different functional forms of the Engel curve, namely linear, double logarithmic, and Working-Leser, for six different income groups. Using household level data for the year 1984-85, focussing on the impact of household-size and household composition on expenditure patterns. Estimates presented in the paper indicate that the coefficients corresponding to total household expenditure follow a cyclical pattern across different income groups. This is explained in terms of quantitative as well as qualitative changes in the consumption basket. They also point to the existence of economies of scale in the consumption of some of the commodities. The economies of scale are not only different across commodities but also vary widely across income groups. The evidence further highlights that, in general, the composition of the households does not have a significant impact on the consumption patterns in Pakistan.
