Equilibria in security markets with a continuum of agents
(Escola de Pós-Graduação em Economia da FGV, 2003-11-01)
We prove the existence of a competitive equilibrium for exchange economies with a measure space of agents and for which the commodity space is ` p, 1 < p < +∞. A vector x = (xn) in ` p may be interpreted as a security which ...

Competitive equilibria in infinite-horizon collateralized economies with default penalties
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2010-03-16)
Araújo, Páscoa and Torres-Martinez (2002) have shown that, without imposing either debt constraints or transversality conditions, Ponzi schemes are ruled out in infinite horizon economies with default when collateral is ...
Sensitivity analysis of markup equilibria in complementary markets
(Elsevier, 2014)
We study the competitive structure of a market in which firms compete to provide various products
within a bundle. Firms adopt price functions proportional to their per-unit costs by selecting markups.
We consider two ...
Alternative dynamics and stability results in a standard OLG model: an interpretation

Modeling and stability analysis of a microalgal pond with nitrification
(Elsevier, 2017)
Microalgae culture fed with ammonium may face the presence of nitrifying bacteria. The aim of this paper is to propose and analyze a nonlinear system which represents the dynamics of these two species (microalgae and ...
Rolf Mantel and the Computability of General Equilibria: On the Origins of the Sonnenschein-Mantel-Debreu Theorem
(Duke University Press, 2007-12)
In this brief paper we revise the original motivations of Rolf Mantel to pursue a proof of Sonnenschein´s conjecture. We contend that his work on computational models of general equilibrium lead him to seek an alternative ...
On a competitive system with ideal free dispersal
(Academic Press Inc., 2018)
In this article we study the long term behavior of the competitive system {[Formula presented]=∇⋅[α(x)∇[Formula presented]]+u(m(x)−u−bv)inΩ,t>0,[Formula presented]=∇⋅[β(x)∇v]+v(m(x)−cu−v)inΩ,t>0,∇[Formula ...
Essays on competition and returns of inside money
(2003)
In an early paper, Cavalcanti and Wallace (2001) showed, using a computable version of Cavalcanti-Wallace model (CW-1999), that optimal regulation induces banks to pay interests, instead of contracting the money supply in ...
