We are interested in proving an equilibrium existence result in a general equilibrium model with incomplete nominal asset markets. When we relax the assumption of strict positivity of initial endowments, then, as it is the case for every general equilibrium existence problem, we need to...

This note provides an intuitive and simple proof of the existence of equilibrium in an incomplete ffnancial economy with numeraire assets, when the preferences are represented by concave, strictly increasing functions..

In this paper, several problem reduction techniques are discussed that can be used to reduce the solution time of set partitioning problems. These techniques can be applied in any solution algorithm for set partitioning problems. Besides a short review of the existing literature on preprocessing...

In this paper we argue that in realistically calibrated two period general equilibrium models with incomplete markets CAPM-pricing provides a good benchmark for equilibrium prices even when agents are not mean-variance optimizers and returns are not normally distributed. We numerically...

We build a general equilibrium model where agents are subject to endogenous trading constraints, making the access to financial trade dependent on prices and consumption decisions. Besides, our framework is compatible with the existence of endogenous financial segmentation and credit markets'...

We prove existence of equilibria with proportional transaction costs on asset trading, using homotopy methods.
