This paper contains a general equilibrium model of an economy with incomplete markets (GEI) with money and default. The model is a simplified version of the real world consisting of a non-bank private sector, banks, a central bank, a government and a regulator. The model is used to analyse...

In this paper we provide a characterization of the welfare properties of rational expectations equilibria of economies in which, prior to trading, agents have some information over the realization of uncertainity. We study a model with asymmetrically informed agents, treating symmetric...

A substantial literature addresses the negative eect on welfare of the release of information in a competitive market economy. We show that the value of information in this setting is typically positive if asset markets are suciently incomplete. More specically, for any competitive equilibrium...

We study a general equilibrium model in which firms choose their capital structure optimally, trading off the tax advantages of debt against the risk of costly default. The costs of default are endogenous: bankrupt firms are forced to liquidate their assets, resulting in a fire sale if there is...

The paper presents a two-country macroeconomic model in which the number of financial assets is endogenous. Imperfect substitutability of assets and international transaction costs give a comparative advantage to large markets, because of demand effects. Agents have more incentives to undertake...

We study a dynamic general equilibrium model in which firms choose their investment level and their capital structure, trading off the tax advantages of debt against the risk of costly default. The costs of bankruptcy are endogenously determined, as bankrupt firms are forced to liquidate their...

We provide a novel theoretical analysis of how index investing affects capital market equilibrium. We consider a dynamic exchange economy with heterogeneous investors and two Lucas trees and find that indexing can either increase or decrease the correlation between stock returns and in general...

Market liquidity is typically characterized by a number of ad hoc metrics, such as depth, volume, bid-ask spreads etc. No general coherent denition seems to exist, and few attempts have been made to justify the existing metrics on welfare grounds. In this paper we propose a welfare-based...

Following the framework of Cetin et al. (finance stoch. 8:311-341, 2004), we study the problem of super-replication in the presence of liquidity costs under additional restrictions on the gamma of the hedging strategies in a generalized black-scholes economy. We find that the minimal...

Market liquidity is typically characterized by a number of ad hoc metrics, such as depth (or market impact), volume, intermediation costs (such as breadth) etc. No general coherent denition seems to exist, and few attempts have been made to justify the existing metrics on welfare grounds. In...
