This paper develops a micro-founded general equilibrium model of the financial system composed of ultimate borrowers, ultimate lenders and financial intermediaries. The model is used to investigate the impact of uncertainty about the likelihood of governmental bailouts on leverage, interest...

This paper studies the quantitative properties of a general equilibrium model where a continuum of heterogeneous entrepreneurs are subject to aggregate as well as idiosyncratic risks in the presence of a borrowing constraint. The calibrated model matches the highly skewed wealth and income...

In this note we generalize the Negishi approach to equilibrium. We embed a standard one-period exchange economy into a two-period model, where agents' first-period utility functions can be any strictly increasing and concave functions satisfying the lower Inada condition, and prove the existence...

We provide conditions on a one-period-two-date pure exchange economy with rank-dependent utility agents under which Arrow-Debreu equilibria exist. When such an equilibrium exists, we derive the state-price density explicitly, which is a weighted marginal rate of substitution between the initial...

Portfolio constraints often prevent financial derivatives from being synthetically created by primitive assets and thus, open a way for the 'redundant' assets to participate in expanding risk-sharing opportunities. They bring about peculiar portfolios, called 'link portfolios,' at an aggregate...

Investors have different preferences for portfolio skewness and kurtosis, i.e. return asymmetry and tail fatness. We build up a new equilibrium model with three types of investors whose preferences can be characterized by "MV", "MVS" and "MVSK". (M: Mean V: Variance S: Skewness K: Kurtosis) and...

The paper studies the equilibrium value of bid-ask spreads and time- to-trade in a continuous-time, intermediated financial market. The endogenous spreads are the price at which brokers are willing to offer immediacy. In case intermediaries pay trading costs, it includes them too. We determine...

We examine a production-based asset pricing model with an unobservable mean growth rate ollowing a two-state Markov chain and with an ambiguity averse representative agent. Our model requires a low coefficient of relative risk aversion to produce: (i) a high equity premium and volatile equity...

In this paper, I compare the accuracy of the two existing methods for solving stochastic general equilibrium models with dynamic portfolio choice and incomplete markets: one proposed by Hnatkovska (2010) and Evans and Hnatkovska (2005, 2011) (EH), another - attributed to Devereux and Sutherland...

We model tax evasion in the context of an endogenous growth model with two actors: a private agent and the government. The private agent invests his/her endowment of physical capital in the production of a private good. The income derived is used for consumption activities and to finance a...
