We develop an abstract framework to analyze equilibrium existence in dynamic economic models with incomplete financial participation and price dependent financial constraints. Since we do not impose financial survival assumptions, our abstract model is a tool to analyze general equilibrium...

We develop a general equilibrium model with differential information and incomplete financial participation. Agents endogenously update information from commodity prices and financial contracts. Without require financial survival assumptions, we prove equilibrium existence in a model where the...

This paper presents a dynamic general equilibrium model with default and collateral requirements. In contrast with previous literature, our model allows for liquidity contractions and general prepayment specifications. We show that liquidity substantially affects credit and prepayment risks, and...

We characterize essential stability of Cournot-Nash equilibria of generalized games with a continuum of players. As application, we rationalize the active participation of politically engaged individuals as the unique essential equilibrium in an electoral game with a continuum of Cournot-Nash...

It is well known that, under uniform impatience, positive net supply assets are free of bubbles for non-arbitrage kernel deflators that yield finite present values of wealth. However, this does not mean that prices cannot be above the series of deflated dividends for the deflators given by the...

When infinite-lived agents trade long-lived assets secured by durable goods, equilibrium exists without any additional debt constraints or uniform impatience conditions on agents' characteristics. Also, regardless of whether assets' net supply is positive or zero, price bubbles are absent when...

In infinite horizon incomplete market economies, when the seizure of collateral guarantees is the only mechanism enforcing borrowers not to entirely default on their promises, equilibrium exists independently of the choice of collateral bundles.In these economies, we analyze if generic...

We develop a two period general equilibrium model with incomplete financial markets and differential information. Making endogenous the traditional informational restriction on consumption, we allow agents to obtain information from physical and financial markets. Thus, the investment in...

Consider a game with a continuum of players where only a finite number of them are atomic. Objective functions and admissible strategies may depend on the actions chosen by atomic players and on aggregate information about the actions chosen by non-atomic players. Only atomic players are...

When infinite-lived agents trade long-lived assets secured by durable goods, equilibrium exists without any additional debt constraints or uniform impatience conditions on agents' characteristics. Also, price bubbles are absent when physical endowments are uniformly bounded away from zero.
