      abstract = {This paper develops a model for demand-system estimations,  whose coefficients are own-price Marshallian elasticities  and elasticities of substitution between goods. The model  satisfies the homogeneity, symmetry and, eventually,  adding-up restrictions implied by consumer theory. It is  primarily useful for the estimation of the demands of  several goods of the same industry or group of products.  The characteristics of the model are compared to other  existing alternatives (logarithmic, translog, AIDS and  QUAIDS demand systems). The model is finally applied to  estimate the demands for several carbonated soft drinks in  Argentina, and its results are presented together with the  ones obtained with the other estimation methods.},
