Lattice Dynamics of Inequity
2018
Journal of Artificial Societies and Social Simulation
Preserved Fulltext
We discuss a model of inequity based on iteration of the Nash multi-agent bargaining game on a lattice. Agent's choices are based on a logit function and gradual decay of memories of past profits. ...
Numerical simulations demonstrate the stability of various dynamical regimes, such as disorder, fairness or inequity, according to parameters and initial conditions. ...

We consider a ferromagnetic lattice spin system with unbounded spins and investigate the relaxation property for the associated stochastic dynamics (the Glauber dynamics) in the finite volume case. ...
Our result can also be viewed as an extension of the equivalence theorem known for compact spin space settings. ...

Adding fluctuations to the segregation dynamics, we observe a sharp phase transition to lower inequality at a critical temperature, accompanied by a sudden change in the distribution of the wealthy elite ...
A spatial concentration of wealth leads to a steady state with increased global inequality and a magnified distinction between local and global measures of combatting poverty. ...

The most striking insight from these findings is the effect of wealth visibility on the dynamics of inequality: conspicuous inequality breeds more inequality. ...
And how do visibility and social comparisons affect the dynamics of inequality when the relevant game is not one of cooperation but of competition? ...
