This paper develops a model of residential water demand under a nonlinear budget constraint. The theoretical model for an individual consumer is adapted to yield an aggregate model that preserves the structure of the individual demand function, and that can be used with aggregate (water district...

This paper presents several models of the demand for quality differentiated goods in which the consumer decides which brand of product to select as well as how many units to buy. The models cover a variety of preference structures and can readily be estimated using standard techniques for...
