Abstract

In this paper we consider the problem of computing market equilibrium when utilties are homothetic concave functions. We use the Fisher market model. The problem of finding a tâtonnement process for equilibrium in this case has been the subject of recent papers and determining an approximation is of considerable interest. Our buy-sell algorithm starts with an arbitrary price vector and converges to an ε-equilibrium price vector in time proportional to O(1/ε 2). This process attempts to closely mimic the convergence process of real-life markets.
