We study an environment where the capital structure of banks and firms are jointly determined in equilibrium, so as to balance the benefits of the provision of liquidity services by bank deposits with the costs of bankruptcy. The risk in the assets held by firms and banks is determined by the...

We show that repurchase agreements (repos) arise as the instrument of choice to borrow in a competitive model with limited commitment. The repo contract traded in equilibrium provides insurance against fluctuations in the asset price in states where collateral value is high and maximizes...

We present a model of secured credit chains in which assets generated from intermediation activity and pledged as collateral create fragility. A dealer stands between a borrower and a financier. The dealer borrows from the financier to fund her project, subject to a moral hazard problem, In...

At a competitive equilibrium of an incomplete-markets economy agents' marginal valuations for the tradable assets are equalized ex-ante. We characterize the finest partition of the state space conditional on which this equality holds for any economy. This leads naturally to a necessary and...

This paper re-examines the conditions for the existence of local stationary sunspot equilibria (SSE) in the standard OLG model from a broader perspective than before. We say that local SSE exist around a steady state of a given OLG economy if, in any arbitrarily small neighborhood of the steady...

In a fundamental contribution, Prescott and Townsend (1984) [PT] have shown that the existence and efficiency properties of Walrasian equilibria extend to economies with moral hazard, when agents' trades are observable (exclusive contracts can be implemented). More recently, Bennardo and...

We study the role of traders' meeting capacities in decentralized markets with adverse selection. Uninformed customers choose trading mechanisms in order to find a provider for a service. Providers are privately informed about their quality and aim to match with one of the customers. We consider...
