		| Under certain conditions on the excess demand function, it is shown that the set of equilibrium prices coincides with the set of maximizers of a potential function. 
Therefore, monotone comparative statics techniques can be employed to study how equilibrium prices change when there are shocks to the parameters of the model. 
As a by-product of our analysis, it turns out that the set of equilibrium prices is a convex lattice. |
