Collateral avoids Ponzi schemes in incomplete markets
(Escola de Pós-Graduação em Economia da FGV, 2001-05-01)
Without introducing neither debt constraints nor transversality conditions to avoid the possibility of Ponzi schemes, we show existence of equilibrium in an incomplete markets economy with a collateral structure.
The Poisson-exponential regression model under different latent activation schemes
(SOC BRASILEIRA MATEMATICA APLICADA & COMPUTACIONALSAO CARLOS SP, 2013-08-02)
In this paper, a new family of survival distributions is presented. It is derived by considering that the latent number of failure causes follows a Poisson distribution and the time for these causes to be activated follows ...
Harsh default penalties lead to Ponzi schemes: a counterexample
(Academic Press Inc Elsevier Science, 2012-05)
Pascoa and Seghir (2009) presented two examples to show that in the presence of utility penalties for default, collateral requirements do not always eliminate the occurrence of Ponzi schemes and equilibria may fail to ...

On Hilbert schemes and Chen-Ruan cohomology.
(2011-10-13)
Through a geometric approach, we explain the origin of the crepant resolution conjecture of Y.
Ruan. More precisely, we calculate the Chen-Ruan cohomology and the quantum corrections of
Ruan for the cohomology of Hilbert ...
Analysis of a sub-optimal scheme of drug dosage in the AIDS treatment
(2003-11-07)
Here the results for CD4+T cells count and the viral load obtained from HIV sero-positive patients are compared with results from numerical simulations by computer. Also, the standard scheme of administration of drugs anti ...

Stability analysis of Crank-Nicolson and Euler schemes for time-dependent diffusion equations
(Springer, 2015-06-01)
In this paper, we study the stability of the Crank-Nicolson and Euler schemes for time-dependent diffusion coefficient equations on a staggered grid with explicit and implicit approximations to the Dirichlet boundary ...
A scheme for inviscid compressible flow, considering a gas in thermo-chemical equilibrium
(World Scientific, 2015-06)
A finite volume scheme for the solution of the unsteady 1D Euler equations, considering the working gas in thermo-chemical equilibrium, is presented. To achieve total variation diminishing (TVD) properties in the numerical ...
Iterative schemes for finding all roots simultaneously of nonlinear equations
In this paper, we propose a procedure that can be added to any iterative scheme in order to turn it into an iterative method for approximating all roots simultaneously of any nonlinear equations. By applying this procedure ...
