We consider the problem of computing market equilibria and show three results. (i) For exchange economies satisfying weak gross substitutability we analyze a simple discrete version of tÃ¢tonnement,â€¦ (More)

We consider exchange economies where the tradersâ€™ preferences are expressed in terms of the extensively used constant elasticity of substitution (CES) utility functions. We show that for any suchâ€¦ (More)

Over the last few years, the problem of computing market equilibrium prices for exchange economies has received much attention in the theoretical computer science community. Such activity led to aâ€¦ (More)
