On equilibrium existence with endogenous restricted financial participation

Abstract
Without requiring either financial survival assumptions or linear spanning conditions over financial spaces, we prove equilibrium existence in an abstract incomplete market economy with endogenous restricted financial participation. We apply our results to general financial structures including nominal, real and collateralized asset markets.
