We apply Geometric Arbitrage Theory to obtain results in mathematical finance for credit markets, which do not need stochastic differential geometry in their formulation. We obtain closed form equations involving default intensities and loss given defaults characterizing the...

A theory of general economic equilibrium with incomplete financial markets is developed with many new features … money. To this end, equilibrium is given a variational formulation that brings fresh tools to the subject. A different way … framework of the model, the proof of equilibrium is able moreover to proceed under far weaker assumptions than usual on the …

We offer new sufficient conditions ensuring demand is downward sloping local to equilibrium. It follows that … equilibrium is unique and stable in the sense that rising supply implies falling prices. In our setting, there are two goods … utility displays nonincreasing absolute risk aversion, then market demand is strictly downward sloping local to equilibrium …

We propose an equilibrium model for coupled markets of multiple energy sectors. The agents in our model are operators … equilibrium in coupled markets of multiple energy sectors. We illustrate via simple examples that these conditions are indeed … market equilibrium problem in more complex computational multilevel equilibrium models, in which uniqueness of lower levels …

To explain the Pareto tail behavior empirically observed in wealth distributions, the quantitative macro literature has occasionally assumed that agents have random discount factors. This paper formally proves that the stationary wealth distribution in a simple Huggett model with random...

This paper presents a method to construct a sequence of approximate policy functions of increasing accuracy on non-local domains. The method is based upon the notion of stable manifold originated from dynamical systems theory. The approximate policy functions are constructed employing the...
