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...
