This paper considers the long-run effects of BSE on meat consumption in the United Kingdom using data from the Expenditure and Food Survey. We estimate a dynamic AIDS demand system of household food consumption, with long-run effects captured via an adstock index of adverse media coverage. The...

A test of the adding up condition in demand systems is crucial for determining whether a share format is admissible when the number of sample goods is smaller than the number of commodity choices available to consumers. This test requires the estimation of a demand system in a quantity format....

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...

Economic data with substantial seasonality are likely to have unit roots in more than one frequency. Using non-alcoholic beverage expenditure data from the United Kingdom, we empirically show that the absence of unit roots in one frequency (e.g. monthly) does not imply the absence of unit roots...

Food away from home (FAFH) comprises nearly half of all U.S. consumer food expenditures. Hence, policies designed to influence nutritional outcomes would be incomplete if they did not address the role of FAFH. However, because of data limitations, most studies of the response of food demand to...

This paper considers the estimation and testing of demand systems when the number of sample goods is smaller than the number of commodity choices available to consumers. In this case, the demand system is incomplete. The large majority of papers that appeared in the literature specifies and...

This paper analyses the impact of food safety information about the 'mad-cow' crisis on the demand for different types of fresh meat and fish in Spain. The theoretical model explicitly incorporates food safety information in the consumers' utility function, from which demand equations are...

This paper analyses the world demand for fibers using the system-wide approach with three dimension—product X space X time. We investigate to what extent differences in international consumption patterns of fibers can be explained by differences in incomes and prices faced by different...

We consider nested utility function with nonhomothetic subutility functions. We express demand functions for aggregate goods in terms of marshalian and hicksian demands associated with the standard consumer problem of maximization of aggregate utility function. We also presents a simple method...
