Monotone comparative statics in general equilibrium

Francesco Ruscitti, Ram Sewak Dubey

Research output: Contribution to journalArticlepeer-review


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.
