This paper decomposes changes in Marshallian expenditure shares functionover time into economic effects and demographic effect. Economic effects are decomposed into a total substitution effect, an income effects and a habit effect. The analysis is based on the Linearized AIDS model. The empirical results indicate that (i) demographic effect rather than economic effects was the main driving force in explanining changes in expenditure shares for all food items except dairy products and fruits, and (ii) economic effects explaining changes in expenditure shares vary across food items.
