We characterize the essential stability of games with a continuum of players, where strategy profiles may affect objective functions and admissible strategies. Taking into account the perturbations defined by a continuous mapping from a complete metric space of parameters to the space of...

We address a general equilibrium model with limited-recourse collateralized loans and securitization of debts. Each borrower is required to pledge physical collateral, and bankruptcy is filed against him if claims are not fully honored. Moreover, agents have a positive amount of wealth exempt...

In the presence of utility penalties, collateral requirements do not always eliminate the occurrence of Ponzi schemes. Harsh utility penalties may induce effective payments over collateral recollection values. In this event, loans can be larger than collateral costs and Ponzi schemes become...

This paper endogeneizes the utility penalties, initiated by Dubey, Geanakoplos and Shubik (2005), by introducing a benevolent central planner choosing the value of marginal default utility penalties for each consumer. We also prove equilibrium existence with endogenous default penalties for...

Pascoa and Seghir (2009) noticed that when collateralized promises become subject to utility penalties on default, Ponzi schemes may occur. However, equilibrium exists in some interesting cases. Under low penalties, equilibrium exists if the collateral does not yield utility (for example, when...

This paper deals with the existence of equilibrium in a non-classical Overlapping Generations Model with incomplete markets and one-period numeraire assets. The stochastic structure of the model is given by an infinite event-tree in which each node has a finite number of immediate successors....

We are interested in proving an equilibrium existence result in a general equilibrium model with incomplete nominal asset markets. When we relax the assumption of strict positivity of initial endowments, then, as it is the case for every general equilibrium existence problem, we need to...
