O conjunto dos equilíbrios dos leilões de primeiro preço
2004-05-06In this note I specify the class of functions that are equilibria of symmetric first-price auctions. -
Conteúdo material do equilíbrio econômico financeiro de contratos de concessão
2016-02-15The dissertation assumes that the initial establishment of the economic and financial balance in the concession agreements have to use theories, concepts and methodologies of other sciences that not only the legal sciences, ... -
Contracting with repeated moral hazard and private evaluations
2005-11-29A repeated moral hazard setting in which the Principal privately observes the Agent’s output is studied. It is shown that there is no loss from restricting the analysis to contracts in which the Agent is supposed to exert ... -
A contractive method for computing the stationary solution of the euler equation
2002-09-01A contractive method for computing stationary solutions of intertemporal equilibrium models is provide. The method is is implemented using a contraction mapping derived from the first-order conditions. The deterministic ... -
The costs and benefits of leaving the EU: trade effects
2017-10Sampson and John Van Reenen?> This paper estimates the welfare effects of Brexit in the medium to long run, focusing on trade and fiscal transfers. We use a standard quantitative general equilibrium trade model with many ... -
Cournot competition under Knightian uncertainty
1998-11-02This article applies a theorem of Nash equilibrium under uncertainty (Dow & Werlang, 1994) to the classic Cournot model of oligopolistic competition. It shows, in particular, how one can map all Cournot-Nash equilibria ... -
Cournot-nash equilibria in continuum games with non-ordered preferences
2008-05In the usual framework of continuum games with externalities, we substantially generalize Coumot-Nash existence results [Balder, A unifying approach to existence of Nash equilibria, Int. J.Game Theory 24 (1995) 79-94; On ... -
Desequilíbrio cambial e crescimento econômico: uma análise empírica baseada no modelo Balassa-Samuelson
2008-06-06Most empirical approaches only use productivity differentials to estimate the Balassa-Samuelson effect. Despite of that, the Balassa-Samuelson model assumes some important hypotheses that are generally ignored. Initially, ... -
Determinacy of equilibria in nonsmooth economies
1999-11Concavifiable preferences are representable by a function which is twice differentiable almost everywhere, by theorem of Alexandroff [Alexandroff, A.D., 1939. Almost Everywhere Existence of Second Differentials of Convex ... -
A dinâmica da economia brasileira em um modelo DSGE com bancos e empreendedores
2019-08-16Este trabalho busca contribuir para uma melhor compreensão de como fricções financeiras e choques financeiros influenciam no surgimento de novas de empresas e, consequentemente, na dinâmica da economia brasileira. Os ... -
Dynamic markets for lemons
2017-05-12Este trabalho investiga o papel da sinalização em um mercado dinâmico de limões. Nós derivamos propriedades gerais dos equilíbrios, e em particular dos equilíbrios totalmente separantes. O equilíbrio separante mais ... -
Efeitos de gastos do governo em um modelo dinâmico estocástico de equilíbrio geral com restrições financeiras
2010-09Recentes evidências empíricas sugerem que o consumo aumenta em resposta a um aumento nos gastos do governo. Essa descoberta não pode ser facilmente reconciliada com os resultados dos modelos de otimização dos ciclos ... -
Empirical measures,learning and sunspot equilibrium
1998-03-12In this paper we construct sunspot equilibria that arrise from chaotic deterministic dynamics. These equilibria are robust and therefore observables. We prove that they may be learned by a sim pie rule based on the histograms ... -
Endogenous borrowing constraints and default when markets are incomplete
2001-09-17Incomplete markets and non-default borrowing constraints increase the volatility of pricing kernels and are helpful when addressing assetpricing puzzles. However, ruling out default when markets are in complete is suboptimal. ... -
Endogenous collateral
2003-11-04We study an economy where there are two types of assets. Consumers’ promises are the primitive defaultable assets secured by collateral chosen by the consumers themselves. The purchase of these personalized assets by ... -
Endogenous collateral: arbitrage and equilibrium without bounded short sales
2001-05-01We study the implications of the absence of arbitrage in an two period economy where default is allowed and assets are secured by collateral choosen by the borrowers. We show that non arbitrage sale prices of assets are ... -
Endogenous debt constraints in collateralized economies with default penalties
2011-06-30In infinite horizon financial markets economies, competitive equilibria fail to exist if one does not impose restrictions on agents' trades that rule out Ponzi schemes. When there is limited commitment and collateral ... -
Endogenous mechanisms and nash equilibrium in competitive contracting games
2009-09-20We model strategic competition in a market with asymmetric information as a noncooperative game in which each firm competes for the business of a buyer of unknown type by offering the buyer a catalog of products and prices. ... -
Ensaio em competição monopolística
1982-11-02This article treats the topic of monopolistic competition, interpreted as a Cournot oligopoly in market equilibrium. The notion of a Cournot oligopoly is discussed, and its relation to the non-cooperative Nash equilibrium ... -
Equilibria in reflexive banach lattices with a continuum of agents
2004-10We consider exchange economies with a measure space of agents and for which the commodity space is a separable and reflexive Banach lattice. Under assumptions imposing uniform bounds on marginal rates of substitution, ...
