Abstract

We develop a general equilibrium model with incomplete financial participation and price dependent financial constraints. In our model, equilibrium exists even when agents do not have access to all financial contracts. For instance, exclusive credit lines and investment clubs are compatible with our framework. We also extend the literature of incomplete financial participation to include debts backed by price dependent collateral, and non-ordered preferences negatively affected by the amount of default.
