Nonlinear redistribution of wealth from a stochastic approach
Hugo Lima, Allan R. Vieira, Celia Anteneodo
We investigate the effect of applying nonlinear redistributive taxes to the yard-sale dynamics of assets. An amount of money is collected from each individual (tax) and distributed…
Inequality, a scourge of the XXI century
José Roberto Iglesias, Ben-Hur Francisco Cardoso, Sebastián Gonçalves
Social and economic inequality is a plague of the XXI Century. It is continuously widening, as the wealth of a relatively small group increases and, therefore, the rest of the worl…
What is the potential for a second peak in the evolution of SARS-CoV-2 in emerging and developing economies? Insights from a SIRASD model considering the informal economy
Marcelo A. Pires, Nuno Crokidakis, Daniel O. Cajueiro +2
We study the potential scenarios from a Susceptible-Infected-Recovered-Asymptomatic-Symptomatic-Dead (SIRASD) model. As a novelty, we consider populations that differ in their degr…
Skepticism and rumor spreading: the role of spatial correlations
Marco Antonio Amaral, W. G. Dantas, Jeferson J. Arenzon
Critical thinking and skepticism are fundamental mechanisms that one may use to prevent the spreading of rumors, fake-news and misinformation. We consider a simple model in which a…
Barriers, trapping times and overlaps between local minima in the dynamics of the disordered Ising -spin Model
Daniel A. Stariolo, Leticia F. Cugliandolo
We study the low temperature out of equilibrium Monte Carlo dynamics of the disordered Ising -spin Model with and a small number of spin variables. We focus on sequences o…
Hysteresis and disorder-induced order in continuous kinetic-like opinion dynamics in complex networks
A. L. Oestereich, M. A. Pires, S. M. Duarte Queirós +1
In this work we tackle a kinetic-like model of opinions dynamics in a networked population endued with a quenched plurality and polarization. Additionally, we consider pairwise int…
