New existence of equilibria in generalized SSC (Q1609037)

The referred paper contributes to the mathematical modeling of economic phenomena. It generalizes the model of Social Systems with Coordination (SSC) in the sense that some of its rather restrictive assumptions on interier conditions are not used. Namely, the state correspondence and the strong continuity of agent's preference are not considered. The main results are represented by new existence theorems of equilibria proved by means of the Fan-Glickberg fixed point theorem. Moreover, the Nash equilibrium existence for an abstract economy is derived, and some illustrative examples are shown.
