The method of meeting trajectories for a linear production-exchange model

We study the exchange model of economics whose participants include both consumers and companies producing goods. The production capacities of the companies are restricted by the expenses of a certain single resource. We study in detail the version of the model with fixed budgets of the participants. We present and justify a method for finding the equilibrium, which develops the original approach of polyhedral complementarity. Under a rather slight assumption of nondegeneracy we show that the algorithm enables us to obtain the equilibrium state in finitely many steps.
