摘要: In this paper we estimate a complete demand system for Switzerland, with emphasis on food demand, using recent household expenditure survey. The Quadratic Almost Ideal Demand System (QUAIDS) is employed in the analysis of six commodity and non-food groups. quadratic terms QUAIDS were found to be empirically important describing budget behaviour Switzerland. For most groups, inelastic, elasticities ranging between -0.64 -1.02. Cross-price are very low, suggesting limited possibilities substitution All groups necessities, while group luxury. estimated own-price from specification segmented by income show that commodities, (absolutely) consistently higher lower group.
