This paper provides an introduction to and discussion of the application of the lattice programming method to classic comparative statics problems in consumer theory. These include comparative statics over densities and consumer types, and characterizations of income effects. The partial order...

This paper explores and explains the application of the lattice theoretic approach to classic comparative statics in consumer theory. Through examples of preferences that are not quasiconcave, or not differentiable, or not continuous, the approach is shown to characterize income effects more...
