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 provides an overview of Czech food import demand in the transition period of the 90's. It also provides econometrical estimates of own- and cross-price elasticities and group expenditure elasticities of Czech import demand for a number of foods. Based on the Hausman test for...

Diminishing marginal utility is neither necessary nor sufficient for downward sloping demand. Yet upper-division undergraduate and beginning graduate students often presume otherwise. This paper provides two simple counter examples that can be used to help students understand that the Law of...

Diminishing marginal utility (DMU) is neither necessary nor sufficient for downward-sloping demand. Yet, upper-division undergraduate and beginning graduate students often presumeotherwise. This paper provides two simple counter-examples that can be used to help students understand that the Law...
