| RESUMEN: En este trabajo se analiza la demanda de alimentos en España considerando la relación existente entre salud y dieta. Se plantea la maximización de una función de utilidad que depende de las cantidades demandadas de los distintos alimentos y del nivel de salud alcanzado, sujeto a dos restricciones: la presupuestaria y la relativa a la función de producción de salud. La solución al problema conduce a la estimación conjunta de un sistema de ecuaciones con dos componentes, una ecuación referida a la calidad de la dieta y un sistema de demanda de alimentos. Los resultados obtenidos indican, por un lado, que la introducción de la calidad de la dieta en un sistema de demanda (frente a un modelo que incluya únicamente renta y precios) modifica las... |

| The objective of this paper is to analyze the Spanish demand for food taking into account the consumer's concern about the relationship between food diet and health. This concern is forcing food demand analysts to assume that consumer utility is a function of nutrients instead of simply the food products themselves. A CBS demand model has been considered to model the new demand function obtained, which is estimated with a complete panel data set. Ten broad categories, nine nutrients and the most relevant socio-economic variables have been considered. Finally, after an appropriate model selection strategy, expenditure, price and nutrient elasticities, as well as main sociodemographic effects, have been calculated. |

| The objective of this paper is to analyse consumers’ attitudes and acceptability of GM food products in Spain. From the methodological point of view, a three-equation model of consumer behaviour is estimated assuming a kind of causal chain among the degree of knowledge, attitudes and buying intentions. Explanatory variables include socioeconomic characteristics of respondents as well as endogenous variables of the previous equations. The model provides a better knowledge of how attitudes and buying intentions towards GM food are formed. Higher educated consumers, more concerned about labelling information and less about price, and regular buyers of organic foods show a higher (not necessarily better) knowledge on GM technology and its consequences.... |

| In this paper, the Spanish demand for food away from home is analysed. A panel data set is built and appropriate techniques for estimating limited dependent variable models have been applied. Results indicate that where there are zero expenditures, these are largely due to infrequency of purchase rather than to abstention or to economic reasons. Furthermore, important differences appear among households. On the one hand, those households whose head is a highly-educated person, male, young and living on a salary in a large town are more likely to purchase food away from home. On the other hand, increases in income only provokes more than proportional increases in expenditure for those households headed by an unschooled person, a female or a person older... |
