Continuity Properties of Equilibria in Some Fisher and Arrow-Debreu Market Models

Following up on the work of Megiddo and Vazirani [10], who determined continuity properties of equilibrium prices and allocations for perhaps the simplest market model, Fisher’s linear case, we do the same for: – Fisher’s model with piecewise-linear, concave utilities – Fisher’s model with spending constraint utilities – Arrow-Debreu’s model with linear utilities – Eisenberg-Gale markets.
