How simple regulations can greatly reduce inequality
J.R. Iglesias

TL;DR
This paper introduces a simple regulation-based exchange model that significantly reduces wealth inequality by targeting the poorest agents for wealth redistribution, contrasting with traditional models that lead to extreme wealth concentration.
Contribution
The study proposes a novel exchange model using extremal dynamics to effectively decrease inequality, demonstrating that simple regulations can achieve substantial redistribution.
Findings
A simple regulation targeting the poorest agents reduces inequality.
The model prevents wealth condensation and promotes more equitable wealth distribution.
Simple rules can lead to significant wealth redistribution.
Abstract
Many models of market dynamics make use of the idea of wealth exchanges among economic agents. A simple analogy compares the wealth in a society with the energy in a physical system, and the trade between agents to the energy exchange between molecules during collisions. However, while in physical systems the equipartition of energy is valid, in most exchange models for economic markets the system converges to a very unequal "condensed" state, where one or a few agents concentrate all the wealth of the society and the wide majority of agents shares zero or a very tiny fraction of the wealth. Here we present an exchange model where the goal is not only to avoid condensation but also to reduce the inequality; to carry out this objective the choice of interacting agents is not at random, but follows an extremal dynamics regulated by the wealth of the agent. The wealth of the agent with the…
