The analysis of markets with indivisible goods and xed exogenous prices has played
an important role in economic models, especially in relation to wage rigidity and unemployment.
This paper provides a novel mathematical programming based approach to study pure
exchange economies where discrete amounts of commodities are exchanged at xed prices.
Barter processes, consisting in sequences of elementary reallocations of couple of commodities
among couples of agents, are formalized as local searches converging to equilibrium
allocations. A direct application of the analyzed processes in the context of computational
economics is provided, along with a Java implementation of the approaches described in this
