Households' food consumption behaviour in Argentina: A quadratic demand system with demographic effects

The objective of this paper is to analyze household's food consumption behaviour in Argentina by comparing two cross sectional estimations of a quadratic demand system (QES). WE employ data from the National Expenditure Survey at household level (2004-05 and 2012-2013). The estimated system is augmented with demographical variables in order to examine changes across different household types. We estimate quality adjusted prices and we account for any selectivity bias in our data. Additionally, we propose an exercise that consists on calculating equivalence scales frome stiamted expenditures for each household type. Results allow us to analyze and discuss welfare changes over the last decade. In particuluar, changes in food consumption are led by alterations in relative prices; inflation process unequally affects consumption of food categories for different types of households, implying that households' budget is being reallocated.
