Do milk marketing orders affect various demographic groups differently? To answer this question, we use supermarket scanner data to estimate an incomplete demand system for dairy products. We use these estimates to simulate substitution among dairy products and the welfare impacts of price...

We propose a Generalized Quadratic Utility (GQU) model for an incomplete demand system with binding non-negativity constraints which is flexible in income and price effects. The model accounts for zero consumption using choke prices identified by Kuhn-Tucker conditions. The GQU demand system can...

We consider the impact of taxes on the quantity and quality produced by a competitive firm of goods, such as wine, for which market value accrues with age. Our analysis found the following: an increase in the volumetric retail tax collected at sale increases quality, so that the basic...

Gorman’s theory of demand is extended comprehensively to incomplete systems. The incomplete systems approach dramatically increases this class of models. The separate roles of symmetry and adding up are identified in the rank and the functional form of this class of models. We show that...

Engineering models generally find that most consumers are unwilling to adopt energy efficient appliances, even though the financial returns are positive. It is commonly thought that this is either due to market imperfections such as an incomplete credit market, very high intertemporal consumer...
