COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR<br>Propomos um modelo de equilíbrio geral com securitização de ativos pro- tegidos por colateral físico e discutimos o papel do colateral para evitar, em equilíbrio, expectativas pessimistas em relação as taxas futuras de default. As promessas dos ativos garantidos por colateral são securitizadas em famílias de derivativos Pass-through, que dividem o default de forma prorata, ou de Collateralized Loans Obligations (CLO), que permitem diferentes níveis de prioridade entre os ativos dentro de uma mesma família. No caso de defaul

Abstract:

In this work the problematic issue of price determination in economic theory is re-examined. In the first chapter a state-of-the-art survey regarding the existence of equilibrium and the structure of the equilibrium set in price-setting games is provided. In chapter two a new core concept, the Bertrand core, is introduced and characterized. In chapter three a revealed preference perspective upon the Nash equilibria in price-setting games is provided. In chapter four, the issue of Bayesian equilibrium existence is addressed when traders have incomplete information regarding each others' types.

Abstract:

Cette thèse est centrée sur l’étude d’équations issues de la théorie cinétique des gaz. Dans tous les problèmes qui y sont explorés, une analyse des problèmes linéaires ou linéarisés associés est réalisée d’un point de vue spectral et du point de vue des semi-groupes. A cela s’ajoute une analyse de la stabilité non linéaire lorsque le modèle est non linéaire. Plus précisément, dans une première partie, nous nous intéressons aux équations de Fokker-Planck fractionnaire et Boltzmann sans cut-off homogène en espace et nous prouvons un retour vers l’équilibre des solutions de ces équations avec un

Abstract:

Ce mémoire de thèse est consacré à l’équation de Fokker-Planckpartial_ f=∆f+div(Ef).Il est subdivisé en deux parties :une partie linéaire et une partie non linéaire. Dans la partie linéaire on considère un champ de vecteur E(x) dépendant seulement de x. Cette partie est constituée des chapitres 3, 4 et 5. Dans le chapitre 3 on montre que l’opérateur linéaire Lf :=∆ f + div(E f ) est le générateur d’un semi-groupe fortement continu (SL(t))_{t≥0} dans tous les espaces L^p. On y établit également que le semi-groupe (SL(t))_{t≥0} est positif et ultracontractif. Dans le chapitre 4 nous montrons com

Abstract:

The problem of necessary and sufficient conditions for the existence of a unique Cournot equilibrium has been rarely dealt with in the literature, To date there exists virtually only the formulation of the problem given by Kolstad and Mathiesen (1987). Yet several aspects of their approach are debatable. Here, a new formulation is proposed which considers sets of oligopolies rather than single oligopolies. This allows to obtain a new result which brings out the necessity of some important conditions assumed in Kolstad and Mathiesen and often employed to prove the existence of a Cournot equilib

This thesis provides new equilibrium existence results for markets with information asymmetries and relates them in a novel way to the role of economic intermediation. Under atomless uncertainty, single market linear price equilibria are known not to exist prevalently even when agents are risk averse expected utility maximizers. The notion of prevalence involves essentially picking an economy at random. Bypassing the nonexistence problem is one of the achievements of the nonlinear price decentralization theory.

碩士<br>國立臺灣大學<br>數學研究所<br>101<br>Brouwer’s fixed point theorem is critical to the existence of general equilibria in a complete market. However, [4] pointed out that in an incomplete market, a general equilibrium does not always exist. In this paper, following [2] and [6], we use the invariant property of mod 2 Euler number of Grassmannian manifold to derive a fixed-point-like theorem, and therefore, prove the existence of a weaker “pseudo-equilibrium”. At last, we discuss the genericity of general equilibria, that is, the economy in which the equilibria exist is an open and dense set.
