Abstract

Utilizando datos a nivel de hogares de la Encuesta de Ingresos y Gastos2006-2007, estimamos cuatro diferentes especificaciones de sistemasde demanda para Colombia, a saber, el sistema lineal de gastos (les),el sistema lineal de gastos extendido (eles), el sistema cuasi ideal dedemanda (aids) y el sistema cuasi ideal de demanda cuadrático (qaids).También calculamos valores de elasticidades gasto, ingreso y precio para diferentes grupos de bienes. Encontramos que la elasticidadgasto de los alimentos se ha mantenido estable a través del tiempo,entre 0,71 y 0,77 para el conjunto de hogares urbanos. Sin embargo,al comparar hogares de diferentes quintiles de ingreso, encontramosque esta elasticidad varía entre 0,58 y 0,85. Este hallazgo debe tenerseen cuenta en el diseno de la política pública. Por su parte, bienes comola salud, la educación y el transporte han dejado de ser bienes de lujoy ahora son bienes necesarios o bienes de elasticidad gasto unitaria,dependiendo del sistema que se use para estimarla. La reducción enlas elasticidades gasto de estos bienes refleja las políticas que se hanllevado a cabo en el país en las últimas décadas.
