This paper examines links between the way in which a household spreads their food expenditure over time and the dietary quality of the food they purchase. I find that households who make more frequent, smaller food purchases buy healthier foods than households who make fewer, larger purchases....

An exactly aggregable system of Gorman Engel curves for U.S. food consumption is developed and implemented. Box-Cox transformations on prices and income nest functional form. The model nests rank up to rank three. The model is estimated by nonlinear three-stage least squares with annual time...

We consider the impact of taxes on the quantity and quality produced of goods, such as wine, for which market value accrues with age by a competitive producer. Any pair of taxes that includes a volumetric sales tax and any one of three other types of tax – an ad valorem sales tax, an ad...

Duality methods for incomplete systems of consumer demand equations are adapted to the dual structure of variable cost functions in joint production. This allows the identification of necessary and sufficient restrictions on technology and cost so that the conditional factor demands can be...

This chapter presents the indirect preferences for all full rank Gorman and Lewbel demand systems. Each member in this class of demand models is a Generalized Quadratic Expenditure System (GQES). This representation allows applied researchers to choose a small number of price indices and a...

A structural inter-temporal model of agricultural asset arbitrage equilibrium is developed and applied to agriculture in the North-Central region of the U.S. The data is consistent with a unifying level of risk aversion. The levels of risk aversion are more plausible than previous estimates for...

Determining the impacts on consumers of government policies affecting the demand for food products requires a theoretically consistent micro-level demand model. We estimate a system of demands for weekly city-level dairy product purchases by nonlinear three stage least squares to account for...
