Consumption of the Colombian Households, 2006-2007: Estimations of Demand Systems (El Consumo De Los Hogares Colombianos, 2006-2007: Estimación De Sistemas De Demanda)
Using household data from the 2006 Income and Expenditure survey, we provide a new estimation of demand systems for Colombia. We estimate three different specifications of demand systems, namely, the Linear Expenditure System (LES), the Extended Linear Expenditure System (ELES) and the Almost Ideal Demand System (AIDS). We also calculate expenditure, income and price elasticities for different groups of goods. We find that the expenditure elasticity of food has remained stable over time, around 0.77. Clothing is no longer a luxury good and has become a good with unitary expenditure elasticity. Health and Education are still luxury goods but their expenditure elasticities have decreased over time.
