Abstract: Hasta la fecha, la mayor parte de los trabajos que han estudiado la demanda de alimentos en Espana han considerado unicamente datos de series temproales o de seccion cruzado. El principal objectivo de este estudio consiste en considerar conjuntamente las dos dimensiones para abordar este problema, tralando de ofrecer al lector unas pantas no solo para estimar sistemas de demanda con un panel de datos sino tambien para contrastar su correcta especificacion. Una segunda caracteristica de este trabajo consiste en definir un esquema general a partir del cual se pueda especificar una forma funcional del sistema de demanda que mejor se ajuste a la informacion disponible, en vez de seleccionar a priori una forma funcional determinda. Los resultados empiricos obtenidos estan en la linea de trabajos anteriores, si bien las elasticidades gasto y precio directas calculadas son ligeramente superiores, sobre todo en el caso de los productos precederos. Al analizar los efectos de las caracteristicas sociodemograficas de los indiciduos, la edad y el porcentaje de miembros de la familia menores de 13 anos son los principales determinantes del consumo de carnes, pescados y azucar, experimentandose un descenso en las cantidades consumidads de estos productos conformen aumentan dichas variables...The demand for food in Spain has been traditionally studied only considering time series or cross section data. This paper aims to analyse food demand jointly considering both data dimensions. It also provides some guidance on how estimate demand systems using a panel data set and on how to carry out misspecification tests. The second main characteristics of this paper is that instead of selecting an a priori functional form, we provide a flexible approach from which the functional form which fits better the data can be selected. Empirical results are consistent with those found in precious literature although expenditure and price elasticities are slightly higher for perishable products. As far as the socio-demographic characteristics of households, the age and the percentage of household members below 13 years are main determinants of meat, fish, and sugar consumption. Consumed quantities of these products decrease as the two considered variables increase.
