Abstract

Con el fin de permitir respuestas renta no lineales en el modelo Almost Ideal Demand System (AIDS) de Deaton y Muelbauer (1980, se propone un sistema de demanda que introduce funciones segmentadas. Este modelo de demanda es estimado con la serie temporal de consumo per cápita de la Economía a Española que abarca desde 1954 hasta 1987. También se analiza el comportamiento empírico del Sistema Quadrático de Gasto (QES) de Howe, Pollack y Wales (1979), y de la extensión cuadrática del modelo AIDS (QAIDS) de Deaton (1984). Por último, se estudia el comportamiento teórico de todos los sistemas estimados, contrastando las restricciones que ser derivan de las propiedades impuestas por la teoría económica sobre la función de gasto. With the aim to incorporate nonlinear income responses in the Almost Ideal Demand System of Deaton and Muelbauer (1980), I propose a generalization of the model, which uses linear spline functions. The model is estimated with the time series of the Spanish economy from 1954 to 1987. I also estimate the well known Quadratic Expenditure Systems (QES) of Howe, Pollack and Wales (1979) , and the quadratic extensión of the AIDS (QAIDS) of Deaton (1984). I compare the results and I investigate the verification of the properties imposed by economic theory on the estimaated expenditure functions.
