Hydrodynamics of Cooperation and Self-Interest in a Two-Population Occupation Model
Jerome Garnier-Brun, Ruben Zakine, Michael Benzaquen
We study the hydrodynamics of a system of agents who optimize either their individual utility (self-interest) or the collective welfare (cooperation). When agents act selfishly, th…
Unlearnable Games and "Satisficing'' Decisions: A Simple Model for a Complex World
Jerome Garnier-Brun, Michael Benzaquen, Jean-Philippe Bouchaud
As a schematic model of the complexity economic agents are confronted with, we introduce the ``SK-game'', a discrete time binary choice model inspired from mean-field spin-glasses.…
Socioeconomic agents as active matter in nonequilibrium Sakoda-Schelling models
Ruben Zakine, Jerome Garnier-Brun, Antoine-Cyrus Becharat +1
How robust are socioeconomic agent-based models with respect to the details of the agents' decision rule? We tackle this question by considering an occupation model in the spirit o…
Thermodynamic bounds on correlation times
Andreas Dechant, Jerome Garnier-Brun, Shin-ichi Sasa
We derive a variational expression for the correlation time of physical observables in steady-state diffusive systems. As a consequence of this variational expression, we obtain lo…
A new spin on optimal portfolios and ecological equilibria
Jerome Garnier-Brun, Michael Benzaquen, Stefano Ciliberti +1
We consider the classical problem of optimal portfolio construction with the constraint that no short position is allowed, or equivalently the valid equilibria of multispecies Lotk…
